Direct answer: A maker buying agarwood is buying wounded wood with a paper description — a named tree, a known district, a resin band, a form as shipped, and a water reading, each tied to a method. Until that description exists, every figure on the table is a number with no referent.
Key facts:
- The traded wood is the dark core that forms around injury; how much of it a piece holds varies block by block, even inside one log.
- Most volume on the market is farmed. Forest wood is limited, takes decades to lay down, and often needs licences.
- Chinese dealers sort density with a basin of water. 奇楠 sits outside that ladder rather than at its top.
- Fakes are built to pass a float check, so checking needs more than one signal and a lab for species.
- Numbers and floors are quoted case by case. The comparison that counts is landed cost per usable unit.
- A piece proves a product. A trial proves a seller.
What the Word Names
Direct answer: The word names a state of wood, not a product line. A healthy Aquilaria stem is pale, light, and nearly scentless; the dark deposit comes only after the tree is wounded or infected, and it settles unevenly around the damage.
The biology sets the trade difficulty. A tree that has never been damaged has barely anything to sell. Once bark or sapwood is breached — by weather, insects, animals, or a grower’s blade — the tree walls off the injury with a dense, scented deposit. That deposit is what a burner recognises. The pale fibre around it is filler.
The deposit rarely fills a trunk like liquid in a bottle. It follows the wound, spreads along the grain, and leaves untouched wood beside loaded wood. Two blocks cut from one log can sit at opposite ends of the quality range, and neither is mislabelled. This is the first reason a bare figure is unreadable: the seller may be describing the best face of a mixed lot, the average, or the worst.
The price mechanism works the same way. Deposit occupies space that fibre would otherwise fill → density climbs → a kilo holds more scent and less inert wood → the useful yield per kilo rises → the asking figure rises with it. What shifts hands, in the end, is scented mass rather than weight.
Two trees dominate the trade a maker will meet. Aquilaria sinensis (白木香, báimùxiāng) is native to the south of China and holds a long domestic history. Aquilaria malaccensis is the chief source across the region and sits on the CITES lists. Hainan and Vietnam are held in high regard among Chinese buyers that lifts both the asking figure and the story wrapped around it. The agarwood ingredient page covers the botany and the legal standing in more detail.
Standing deserves its own note. A famous district can ship plain wood; an unknown farm can ship excellent wood. Paying extra for a name is defensible when the name is on paper and the piece supports it. Paying for the story alone is another transaction, and it is not purchasing.
The Basin Test and What It Cannot Show
Direct answer: A piece that stays up, hangs in the basin, or goes down is being sorted by density, and density tends to track deposit. The check is a useful first sort and a weak proof, as mass can be added with no deposit at all.
Chinese dealers use three working bands: 沉水 (chénshuǐ), which goes down; 半沉半浮 (bàn chén bàn fú), which hangs in the water; and wood that stays at the surface. The names describe behaviour, not botany. A fourth term, 奇楠 (qínán), gets used as if it were the next step up, and that is where the terms mislead.
| Behaviour in water | Trade band | How it acts on heat | Where makers use it |
|---|---|---|---|
| Stays at the surface | Floats | Light, brief, mild | A backing note inside a blend |
| Hangs mid-basin | 半沉半浮 | Medium body, slow fade | Daily sticks, coils, blend stock |
| Goes down | 沉水 | Dense, long, deposit-forward | Premium sticks, chips, heating |
| Soft, dents under a fingernail | 奇楠 | Fragrant before any heat | Hobby pieces, small top-note work |
奇楠 is a state of its own, not a higher score. Dealers describe it as oil holding wood together in place of wood holding oil; it feels soft, releases scent at room temperature, and turns up far less often than the sinking bands. Rarity makes it a target for swapping, which is why the qínán buying guide exists as its own page.
A float result establishes density. It does not establish species, district, or honesty. Wood loaded with oil or resin is made to sink, and it will pass the basin with no argument. Treat the water as one clue among many, never as the last one. The wider terms, with the five-colour ladder used by some dealers, sit in the agarwood grading guide.
Farmed Wood, Forest Wood, and the Paper Behind Each
Direct answer: Most stock on the market is farmed, and the useful asks are which farm, which wounding method, and which band it can repeat — not if farmed wood is real.
A farm works to a schedule. Growers wound standing trees, sometimes with a cultured inoculum, wait while the tree answers, and cut when the deposit has had time to develop. The cycle is long by agricultural measures and short by forest measures, which is the reason farmed wood can be sold as a steady product: same district, same method, a similar band across cuts, and enough volume to reorder.
Forest wood tracks no schedule. The tree is wounded by chance, the deposit accumulates over decades, and what reaches the market is whatever survived. Strength can be extraordinary. Predictability is not part of the offer, and the paperwork can be heavy: wood from listed species may need licences before it crosses a border.
| Ask | Farmed | Forest |
|---|---|---|
| Can the band be repeated next season? | In most cases, within a range | Rarely |
| Is the figure steady? | Comparatively | No |
| What paper travels with it? | Farm records, species sheet | Species sheet plus licences where listed |
| What does it offer a line? | Continuity | Strength and story |
The farm label says how the tree was grown. It says little about deposit load, and it is not a quality grade. A careful farm can produce serious stock; a careless one can produce wood that is technically farmed and aromatically thin. The same caution runs in reverse for “wild,” which is an origin rather than a promise.
Form, Grind, Wetness
Direct answer: The form you receive decides which problems travel with the lot. Chips keep their shape, powder exposes far more surface to air, and wetness decides how either acts once it reaches the mill.
Three lines belong in every order, whatever the band: form, grind for powder, and water content with the method used to read it.
- Form. Blocks, chips, or milled powder. Chips keep their shape and resell on their own; powder is what sticks, cones, and coils consume.
- Grind. The sieve the powder passes, plus the allowance for oversize. An even spread packs and burns evenly; a wide one leaves hard flecks that scorch.
- Water. The reading at dispatch and the method behind it — oven, meter, or estimate. A figure with no method behind it is a rumour with a decimal point.
Grind is easier to check than to describe. A sieve stack sorts powder into bands, and the useful figure is not one number but the shape of the spread: how much rests above the working screen, how much passes the finest, and how much sits in the middle. Oversize particles behave like grit — they scorch at the tip before the rest of the rod has caught — while the finest dust packs into the binder and slows the burn. A mill that reports only “fine powder” has told you little about the spread. Ask for the sieve designation, the share held on each screen, and the milling date; powder shifts as it sits, and a sheet from last season covers another lot.
Dust brings a handling cost too. A powder with a heavy fine fraction cakes at the bag mouth, lifts when the lid comes off, and coats the mixer before it reaches the paste. Static in a dry room makes it worse. That is a workshop nuisance rather than a defect in the wood, and it becomes a wood fault when the dust is lost in handling and the delivered weight no longer matches the recipe.
The mechanisms behind the complaints are not mysterious. Powder carrying too much water → particles stick and cake in the bag → mould risk climbs in a warm store → the burn spends heat driving water off in place of releasing scent → the stick reads dull and may gutter. Powder that is too dry → the paste turns crumbly at the die → rods crack in handling → the burn runs hot and fast → the scent flashes and dies. Neither failure is the seller’s fault by default; both are brief failures.
The window is set by the binder, the rest of the recipe, and the dampness of the room. Numbers do not carry between shops with another press, climate, or recipe. The powder and resin guide covers the format trade-offs, and the manufacturing quality-control guide holds the same logic down the line.
How Powder Becomes a Stick
Direct answer: A buyer who understands the next step writes a better powder brief. A stick is not powder pressed into a shape; it is a paste, a forming route, and a drying schedule working together.
Binder comes first. A Japanese-style stick may rely on makko, a bark powder that burns cleanly and holds scent quietly. A Chinese or Indian masala may use a gum, a resin, or a honey-water mix. A charcoal-core stick is another architecture: scented paste coats a combustible core in place of forming the whole rod. Each route asks its own thing of the agarwood. A binder that wants a fine, dry powder will misbehave with a damp, coarse one, and no lab sheet on the wood can predict that.
Mixing is where water turns into a number. Powder and binder are combined with water until the mass holds and does not stick to the bowl. Too little water and the paste crumbles at the die; too much and the rod slumps, dries slowly, and cracks as it shrinks. The mixer’s hand is a real instrument, but it is not a record. A shop that logs water added, batch weight, and room damp can repeat a result next month; one that works by feel repeats it only while the same person stands at the bench.
Forming offers two common routes. Extrusion forces paste out of a die, fixing diameter and surface finish. Hand-rolling winds paste around a splint or presses it coreless, leaving small variations in density that change how the stick lights and how it burns down. Neither route is superior in the abstract. The test is a full run against the agreed brief, not a pretty sample.
Drying is the step most often underestimated, and it produces the clearest failure chain in the process. A rod leaves the die soft and water-heavy → it is racked in moving air → surface water leaves first while the core stays wet → if the rod is pulled early, a damp core sits inside a dry skin → it lights unevenly and the hidden water cools the flame. Rush the other way and the chain inverts: surface shrinks ahead of the interior → tension builds along the skin → hairline cracks open → the rod fails in the box, not on the shelf.
Curing comes after drying in some traditions. Finished sticks rest in a sealed space for days or weeks while water equalises and the scent settles. The rest adds little; it redistributes what is already present. A stick judged straight off the rack is not the same object as that stick after a month in a closed box, and a buyer who signs off the first has signed off a moving target.
All of this shows why a trial batch beats a piece in the post. The piece says what the wood is. The trial says what it does when it meets your binder, your water, your die, and your drying room. The second answer decides if an order can become a product.
What the Flame Does
Direct answer: Scent leaves the wood before the wood burns, and that is why a stick perfumes the air. Deposit turns to vapour at temperatures well below the point where cellulose breaks down, so the scent load reaches the nose ahead of the smoke.
Watch a lit tip closely and the process separates into stages. Heat comes from the coal behind the tip; water leaves first; the scent fraction vaporises and drifts upward; the woody structure then chars and gives the visible smoke. A piece with a heavy deposit releases more scent in that middle stage, which is why good wood smells generous before it smells burnt.
Packing shifts the stages. A fine, tightly pressed powder leaves little space for air between particles → the coal creeps forward slowly and coolly → more of the scent fraction distils in place of combusting → the burn is slower and rounder, and the risk of going out rises. A coarse, loosely packed rod lets air in → the coal runs hot → scent is burned rather than distilled → the scent turns sharp and the finish is ashy. Neither outcome is a property of the wood alone; both are properties of the rod.
Water sits in the same chain. Turning water into steam consumes heat, so a damp core steals warmth from the coal → the tip cools → the burn stalls, gutters, or tunnels down one side. A stick that is too dry has the opposite fault: it runs hot, races over the scent fraction, and leaves a thin, papery finish. The target window is narrow, and it belongs to the product, not to the wood.
Binder behaviour finishes the picture. Makko burns to a clean ash and adds little of its own; some gums leave a harder residue and a heavier smoke; a charcoal core shifts where the heat sits and how fast the rod advances. A buyer who knows the burn it wants can ask for a grind and a water reading that suit it. A buyer who only asks for “the best wood” has left the outcome to the press operator.
Residue is the last page of the test. Clean grey ash that falls apart suggests a complete burn and a modest binder load; a hard, dark clinker suggests gum, mineral matter, or a core that never fully burned. A greasy film on the burner points back to loading or to a deposit that was never properly cured. None of these readings names a species, and all of them tell you if the rod is behaving the way the brief asked.
Three Ways a Kilo Is Doctored
Direct answer: Doctoring takes three usual shapes: pale wood stained and perfumed, a tree from another family dressed in the name, and low-grade wood loaded with oil or resin to raise its weight.
The cosmetic route starts with non-loaded Aquilaria wood, dyes it dark, and soaks it in scent. The tell is evenness — the deposit is patchy and tracks the grain, while a soaked piece is generally coloured to the edge of every face. The plant route swaps the species entirely: a cheaper wood, scented and passed off as agarwood. Anatomy is the only trustworthy tell, and anatomy needs a lab. The structural route loads poor wood with oil or resin so it gains weight, which is why such wood can pass a float check that honest low-grade wood would fail.
Checking works as a sequence rather than a single trick. Cut a face and look at how the deposit sits. Warm a sliver gently and see if the scent opens in stages. Burn a small piece and read the smoke and the residue. Float a piece, knowing what the float can and cannot prove. Each step costs minutes; none is final alone.
The authentication database collects recorded cases, and the substitution cross-reference shows how one trade name can hide more than one kind of wood. Both are useful before a bargaining session, not after it.
Drawing a Sample Worth Keeping
Direct answer: A piece is proof only when it was pulled to match a description on paper, taken from the lot actually offered, and sealed before anyone handled it.
Put species, district, growing method, band, form, grind, and water on one page. Send the page and ask for a piece drawn to match it. A beautiful piece with no reference to that page is a gift, not a sample. In a warehouse, draw from more than one spot in the stack; at a distance, ask who drew the piece and how it was chosen. Wood from the top of the sack shows the best case, never the case being priced.
Then run the checks: warm a sliver, burn a sliver, cut a face, float a piece. Seal the portion you accept, label it with date and batch code, and keep it. Every later arrival gets compared with that sealed piece rather than on memory. What a piece cannot show is repetition; a trial order answers that. The samples program sets out the wider process.
Writing a Brief That Can Be Enforced
Direct answer: A brief becomes enforceable when each attribute names a method, a limit, and a remedy. Strip out the third and the first two become decoration.
| Attribute | Wording that invites argument | Wording that can be checked |
|---|---|---|
| Band | “Sinking grade” | Test method, piece size, water temperature, observation time |
| Water | “Dry” | Method, tested portion, tolerance either side of target |
| Grind | “Fine powder” | Sieve designation, oversize allowance, milling date |
| District | “The region” | District, farm or forest, seller batch code |
| Acceptance | “Buyer’s satisfaction” | Named inspector, window, sealed reference, remedy |
The acceptance clause decides if a dispute can be won. “Buyer’s satisfaction” sounds protective and is close to unenforceable, as it names a feeling rather than a test. A named inspector, a stated inspection window, a sealed reference piece, and a remedy — replacement, credit, or return — turn the feeling into a procedure.
Figure and order floor belong in the same paper, but they come last. Band, form, amount, port, and paper all move the figure. Ask what shifts it, what the floor is for this exact combination, and which papers travel with the batch. Currency and validity belong in the same conversation; a number with no expiry is not an offer.
Paper, Weight, and What Each Proves
Direct answer: Weight, papers, and lab work each answer one question and leave a second one open; the buyer has to know which is which.
| Figure or sheet | What it establishes | What it leaves open |
|---|---|---|
| Gross weight | Stock plus packing | If tare was weighed or estimated |
| Net weight | Stock as delivered | If the basis is dry |
| Dry-basis weight | Weight at a stated water content | If the method was agreed |
| Species sheet | Which tree, which district, per the seller | If the wording is true |
| Analysis sheet | Deposit, water, grind as tested | If the tested piece represents the lot |
| CITES permit, where listed | Legal travel | If the wood matches the permit |
| Phytosanitary paper | Plant-health admission | Which species |
Paper proves a claim, not the stock behind it. Check the issuer, match the amount and species to the invoice and batch code, and reject a sheet vague enough to describe any consignment in the trade. A lab can identify anatomy, measure water, test microbial load and residues, and report deposit under a named method. It cannot make a non-representative piece represent a ton. Commission a test on a specific ask rather than an abstract worry.
Water deserves its own paragraph: most disputes begin there. An oven-dry result is the reference: a weighed portion is dried to a steady mass, and the loss is reported as a percentage. A handheld meter gives a comparative reading in seconds and is useful for sorting pieces on a table, not for settling a claim. The portion counts as much as the instrument — a chip and a powder dry at unlike rates, and a surface reading on a damp day reads the room as much as the wood. Write the method, the portion size, and the tolerance into the brief, then read the arrival with the same instrument the seller used. Two procedures produce two numbers and one argument. The factory vetting guide turns this paper into a seller list.
From Quoted Figure to Cost per Unit
Direct answer: The figure per kilo is an input, not the cost of the product. Yield, water loss, rejects, freight, duty, and tied-up capital sit between the offer and the finished unit.
Build the model backward from the unit you will sell. A kilo of wet stock delivers less dry stock than the invoice implies, and the water was paid for at wood price. A band that raises the reject rate lifts the effective cost of every good unit, as the failures carry the same freight and duty as the successes. Payment terms lock capital for the journey and output window, and no quotation shows that cost.
The habit is to compare landed cost per usable unit. That needs a trial, a yield measurement, and an honest reject count — more work than lining up two offers, and the only comparison that matches the output call. Suppose one seller quotes less but a tenth of the batch fails inspection; the surviving stock can cost more than a dearer lot that converts cleanly. The arithmetic is the buyer’s own, and no seller will do it for them. The MOQ and pricing guide covers the quotation side.
Clauses, Payment, and Freight
Direct answer: Most disputes about a batch are settled by wording agreed before dispatch, not by the argument after it. Payment and freight terms divide cost, risk, and control, and folding them into one delivered figure hides who is exposed at each step.
| Clause | What it protects | The version that fails |
|---|---|---|
| Tolerance | The line between a deviation and a reject | One figure for every attribute, no remedy |
| Retention piece | The shared reference a dispute is argued over | “Pieces may be kept,” with no custodian |
| Acceptance window | Time to check before money is committed | A window shorter than the lab turnaround |
| Rework | A middle remedy short of rejection | Silent on who pays and what comes after failure |
| Force majeure | Predictability when harvest or export fails | A clause drafted for a factory, not a farm |
| Title and risk | Who owns the goods at each point | Risk passing before a check can happen |
Each weak version removes the middle ground. A contract that offers only accept and reject pushes both sides toward a fight; tolerance, rework, and a named reference give them a path out. Agreeing those clauses before the first order is not pessimism. It is what makes the relationship usable when trouble turns up.
Payment terms deserve the same precision as the stock. A deposit before output, a balance once papers are presented, and a letter of credit each shift risk somewhere. The cheaper-looking term often moves exposure to the moment when the buyer has the least leverage. Freight holds its own constraints: agarwood is bulky relative to value in some forms, picks up water, and frequently crosses borders with licences attached. Stowage factor — the space a given mass occupies — can matter more than weight when a container is planned, and damp in the hold can undo a water target that was right at dispatch. The packaging and shipping guide covers the workings; the buying point is that freight belongs in the brief, not in the aftermath.
Insurance is a set of definitions, and one definition counts more than the rest to a plant buyer: the exclusion for loss caused by the goods’ own state. A policy priced on a low declared value caps recovery at that figure. The chain runs quietly: declare low to save premium → the policy is priced on the declared figure → a total loss occurs → the payout stops at the figure you declared → the gap becomes an uninsured loss. Under-insuring is not a saving. It is a bet that the cargo will not fail.
After It Lands
Direct answer: The first hour after arrival is the cheapest evidence a buyer will collect, and the way the stock is stored decides whether the brief survives the month.
Weigh the stock, take a water reading, photograph the packing and labels, and seal a piece from the delivered batch. Compare it with your reference, not with memory. A weight that matches the invoice and a water reading that does not is a finding. So is stock that looks right and smells flatter than the sealed piece.
Packing should seal against air and water vapour, not merely contain the stock. Powder equilibrates faster than chips and loses its lighter notes sooner. Keep the store dry and closed; a damp corner invites mould, and a hot corner speeds the loss of top notes. The storage and longevity guide covers what happens after receipt.
A buyer who treats storage as part of purchasing avoids complaints that look like seller failures and are really post-arrival losses.
The Broker in the Middle
Direct answer: Many lots pass from hand to hand and never change owner. A broker can add real service — translation, aggregation, licences, freight — and can also add distance between the buyer and the party who must fix a fault.
Trace the chain and the risk becomes clear. Farm, aggregator, broker, exporter, importer: each hand adds cost and removes a little information. A broker may never see the lot, may quote from a photograph, and may be paid by the seller, the buyer, or both. None of that is improper. It becomes trouble only when the buyer assumes the broker is the principal.
Four asks sort the relationship quickly. Who owns the goods at this moment? Who drew the piece I was sent? Whose name sits on the invoice? Who answers if the arrival fails the brief? The answers tell you if you are dealing with a principal who can remedy a loss or an intermediary who can only apologise for one.
A broker earns a place when the alternative is worse. Small lots from a number of farms are hard to assemble alone; export licences and freight are easier with someone who does them weekly; a good broker knows which mill’s word can be trusted. The cost is a margin and a layer of translation, and the fix is documentary: name the mill in the brief, require the batch code on the invoice, and keep the sealed reference in your own store rather than the seller’s.
The trap is a broker who presents a farm’s paperwork as his own. Ask for the mill name and check that the species sheet and permit describe the same lot, not merely the same region. A relationship with a broker is worth having; a relationship with a broker in place of a seller is not.
When Supply Tightens
Direct answer: A rising market shifts which risk dominates, from getting a good figure to getting any stock at the agreed band.
The mechanism is easy to trace and needs no villain. Demand outruns harvest → holders wait for a better figure → spot availability thins at the top bands first → buyers who must produce bid up what remains → the gap between bands widens → buyers trade down → a product briefed on one band quietly receives another. Every step is rational, and the drift comes from a brief that never carried a swap rule.
Forward cover fixes the amount and band for a future arrival. It protects the schedule and puts the risk onto a batch that does not exist yet. The clause that makes it usable is the reference: the future lot is measured by the sealed piece and the brief on paper, with a rejection right if it fails. Cover with no such reference is a bet on a stranger’s harvest.
A qualified second source is slower and worth more. Qualifying an alternative costs pieces, trials, and time, which is why buyers postpone it until a shortage forces the issue. Do it while stock is plentiful, accept a band that overlaps the incumbent’s, and keep the relationship warm with small orders. That alternative is the only thing that lets a buyer refuse a bad batch during a shortage.
Judging Scent in a Salesroom
Direct answer: A salesroom is the worst place to judge scent, as the air already holds other people’s products and your nose has been working all day. Build a quiet test of your own.
Time comes first. A nose needs rest between pieces, and a room needs air. Smell one, step away for a few minutes, then try the next. Five pieces in a row do not produce five impressions; they produce one impression and four adaptations, and the fifth is being judged by a nose that has stopped registering the first four.
Temperature comes second. A cold piece hides its top notes and exaggerates the wood. Warm it gently and the order shifts: light fractions lift first, heavier notes come after. That sequence holds information. A piece that smells complete when cold and adds little when warm may be carrying a surface scent; a piece that is quiet cold and unfolds in stages is behaving like sound wood.
Contrast comes third. Judge a candidate beside a known reference, never in isolation. The reference can be a sealed piece from a passed batch or a wood you already trust. With no reference beside it, “sweet” and “resinous” float free; with one, they become differences. The nose is good at comparison and poor at absolutes.
Wording comes fourth. Most buyers describe scent with a handful of borrowed words and then argue as if the words were measurements. A useful note is concrete: where the sweetness sits, if it comes early or late, if the dry-down is clean or dusty, if the smoke leaves a residue in the throat. Concrete notes last across batches; adjectives do not.
Fatigue comes last, and it is the one buyers deny. After hours in the trade your judgment declines and you will not feel it. Stop. The best test is often the first one after a break, on a piece that has been sealed and labelled.
Why Bad Lots Get Signed Off
Direct answer: Most bad stock is not smuggled past a buyer. It is signed off by one, under a predictable set of pressures.
The first pressure is the piece. A seller chooses what to send, and even an honest seller sends the best one, as that is what pieces are for. The buyer forms an impression from an object that is not representative, and the impression survives into the bulk order. The fix is procedural: draw from more than one spot, ask how the piece was selected, and compare the delivered stock with the sealed reference rather than with the memory of a beautiful piece.
The second pressure is the calendar. A launch date or a customer promise makes “yes” more attractive than “not yet.” Under time pressure the inspection window shrinks, the lab test slips, and the acceptance clause gets signed as drafted. The wood did not improve; the room for the call did. A buyer who knows this sets the window before the launch date is fixed.
The third pressure is social. A seller is pleasant, responsive, and generous with pieces. A buyer who has spent weeks building the relationship does not want to be the person who rejects the lot. That reluctance is human and costly. The defence is to keep the relationship apart from the verdict: a named inspector, a reference on paper, and a remedy that does not require anyone to be called a liar.
The fourth pressure is the spreadsheet. An over-budget order is visible; a slightly wrong order is not. The wrong batch enters the warehouse, gets consumed gradually, and the cost turns up as a hundred small adjustments rather than one bad line. By the time the pattern is clear, the proof has been burned. Intake records matter more than they look, as they turn a slow invisible loss into a dated fact.
A Second Source, Qualified Early
Direct answer: A second source is cheap to qualify while you do not need it and very costly to qualify while you do.
The arithmetic is asymmetric. Qualifying an alternative takes pieces, trials, and time, and produces no revenue. Skipping it produces no cost until the incumbent fails, and then the cost is a rushed swap, a reformulation, and a product change at the worst moment. The expense is deferred, not avoided.
A qualified alternative is also a yardstick. A buyer with two comparable sources knows what the market looks like, can test an incumbent’s figure on a real offer, and can refuse a bad batch and keep the line running. A buyer with one source has a relationship, which is worth having, and no leverage, which is not.
The mistake is to qualify the second source on an identical brief. That produces a substitute that acts the same, which is useful, and a qualification that was easy, which is suspicious. A better second source overlaps but does not duplicate: an outside district, a slightly narrower band, a form the line can absorb. The overlap gives compatibility; the difference gives options. Switching costs also live in the files. A new seller with no kept reference, no batch history, and no intake records is not qualified, even if the first consignment looks right — with no such records, every order is a first order.
Two Bands, One Product
Direct answer: The choice between a middle band with paper behind it and a top band with no paper is not a choice between good and better. It is a choice between two risk profiles, and the product decides which one fits.
Suppose a maker can take a steady 半沉半浮 lot from a named farm, or a 沉水 lot of uncertain origin at a figure that looks like a steal. The instinct is to take the top band, as the label sounds better. Run the comparison on what reaches the customer.
| Question | Middle band, on paper | Top band, no paper |
|---|---|---|
| Can it be reordered? | Yes, inside a stated range | Unknown until a second lot turns up |
| Cost per usable unit? | Predictable once yield is known | Unknown; rejects and water can erase the saving |
| What can the label claim? | A band and a district, both checkable | A band, with little behind it |
| And at a rejection? | Remedy named in the brief | Whoever answers the phone |
| What does the customer notice? | Steadiness across the year | A brilliant first batch, then drift |
The middle band wins four rows and loses one. That is the usual shape of the choice. A top band earns its premium when the product sells on rarity and the claim can be checked; it becomes a liability when the product sells on steadiness and nobody can check anything.
There is a second-order effect. A line built on a steady band can raise its price later by improving the recipe, the finish, or the story. A line built on a trophy batch has to find another trophy next season, at whatever the market asks, or quietly change its nature. Continuity is an asset that never turns up on the invoice.
None of this is an argument for rejecting top-band wood. The argument is about buying it for a product that cannot carry its risk. The band belongs to the wood; the fit belongs to the line.
Old Texts, Modern Claims
Direct answer: The old pharmacy had its own words for this wood — it moves qi and warms the centre — and that is traditional belief, not clinical proof.
Three kinds of record get conflated in a sales pitch. Ritual: centuries of use in temples and homes, real as custom. Textual: a high place in the old manuals of scent, with the basin check as old trade custom. Lab bench: modern work on the resin’s volatile fraction. Each stands inside its own category. None is a claim about what the wood does inside a person. Buy on provenance, band, and steadiness; this page offers no health claim.
The Author’s Stand
Stand: The brief on paper is the only part of an order that survives the people who made it. A buyer who opens with a figure has passed over the question that gives the figure its sense.
Why: One word spans a spread wide enough that two unspecific numbers cannot be compared. Faking goes where the discount is, so haggling before checking is an argument about the nature of a counterfeit. A workshop needs stock it can order again, not a piece it can admire once.
Boundary: “Old and wild” is not a synonym for “right.” Forest wood is not worthless; a maker needs repetition, and forest supply is the hardest supply to repeat. When an exceptional lot turns up at a tempting figure, the question is not how beautiful it is, but if a second lot exists.
Note: An opinion drawn from purchasing habit, not a checked claim about any seller. IncenseHub works with Chinese plant stocks, and this page sets out a buying method rather than making a claim about stock or price.
Yard Terms
Direct answer: Many arguments begin as wording problems, so keep a short glossary and insist that each term means the same thing on both sides of the table.
| Term | Pinyin | What it refers to |
|---|---|---|
| 报价 | bàojià | The quoted figure; ask what it includes |
| 样品 | yàngpǐn | A piece; ask where it was drawn from |
| 大货 | dàhuò | Bulk goods, beyond the single sample |
| 批号 | pīhào | Batch number; the thread that ties records together |
| 留样 | liúyàng | A kept piece, held by both sides |
| 含水率 | hánshuǐlǜ | Water content; the figure behind most disputes |
| 目数 | mùshù | Mesh count; the sieve the powder passes |
| 熏蒸 | xūngzhēng | Fumigation, often a border requirement |
| 提单 | tídān | Bill of lading |
| 让步接收 | ràngbù jiēshōu | Taking a lot below the brief, with an adjustment |
Two terms repay attention. 含水率 is the one to listen for, since a seller who volunteers both a water figure and a method has been asked before. 让步接收 names the concession explicitly, which helps: a middle remedy with a name is easier to haggle over than an argument about goodwill.
FAQ
Q: How does a maker begin an agarwood order?
By writing the stock down before asking what it costs. Settle the acceptable species and district, if farmed or forest wood is allowed, the band the product can carry, and the form and grind the line needs. Put that on one page and request a piece drawn to match it. Two sellers become comparable only when both are quoting on the same page.
Q: Is farmed agarwood good enough for a product line?
For most lines, yes. Wounding starts the deposit on a schedule, so farmed supply regrows and repeats far better than forest supply. It is generally less loaded than wood cut from old forest, and that gap is real. What it offers in exchange is a known district, a steady band, and enough volume to reorder. A line that has to smell the same next year often gains more from that than from a rare piece at peak strength.
Q: How can a buyer spot a doctored lot?
Use more than one check. Cut a face: the deposit is patchy and tracks the grain, while loading pools in channels. Warm a sliver: real wood opens in layers, doctored stock often reads flat or perfumed. Burn a sliver and read the smoke. Float a piece, but do not trust the float alone, as loading is built to pass it. A lab is the only definitive check on species.
Q: What belongs in an agarwood brief on paper?
All that shifts the product: species, district, farm or forest, band, form, sieve range for powder, water content with its test method, packing, batch code, and the acceptance procedure. A brief with no method is an opinion; one with no remedy is a wish. Ask if a third party could check an arrival against that page and reach the same verdict you would.
Q: Why do two farms growing the same species smell unalike?
Since species sets a range, not a fixed scent. The make-up of the deposit shifts with the wounding method, the tree’s years, soil and water, the part of the trunk cut, how long the deposit matured, and how the wood was dried. Two lots of Aquilaria sinensis can share a plant name and land in unalike scent families — one resinous and sweet, a second dry and woody. That is why a brief names the district and the band as well as the species, and why a sealed reference holds more weight than a species sheet alone.
Summary
- Agarwood is the dark, loaded core that forms around injury in more than one tree of the genus Aquilaria, not one uniform staple.
- Species, district, farm or forest, band, form, grind, and water content make up the brief.
- The basin measures density; loading is built to satisfy it.
- A piece proves a product, and only a trial proves a seller.
- Numbers and floors are quoted per case; the meaningful comparison is landed cost per usable unit.
- A band that can be repeated beats a trophy that cannot.
- The process is memory: if the file cannot reconstruct the call, the lesson is lost.
