Spot fake or dyed agarwood chips from Indonesia by checking three things: natural black-brown “tiger-stripe” veining (never a uniform, plastic-black tone), genuine sinking density in water, and a clean, evolving aroma when heated on a hot plate. Dyed, oil-injected, or resin-soaked imitations fail at least one of these tests.
Why are fake and dyed agarwood chips so common?
Agarwood is one of the world’s most valuable raw materials, and that value invites imitation. Market commentary in 2026 notes that superior pure wild agarwood can reach around US$290,000 per kilogram, while artificial or low-grade plantation material may sit near US$100 per kilogram. That gap is so wide that sellers have every incentive to dress up cheap wood as premium resin — dyeing pale kemedangan black, soaking it in fragrance oil, or pressing powder into chip shapes.
For buyers this is a sourcing risk, not a curiosity. Brands ordering white-label material — bulk chips, powder, or private label oud oil — inherit whatever was faked upstream, and a single dyed shipment can stall a product line before it launches. The tests below are the cheapest insurance you can buy.
What does genuine tiger-stripe resin look like?
Real agarwood forms when Aquilaria trees respond to injury or fungal infection by depositing dark, fragrant resin through the wood. That process is slow and uneven, so authentic material shows irregular black-brown veining — the “tiger-stripe” pattern — threading through paler wood. It is never a flat, saturated, plastic-like black across the whole surface.
Indonesian chips are commonly sorted across about nine grades, with the key tiers being Super A, Super B, Super C, and Sabak; the remaining grades mostly denote wood size and resin quantity. Grading rests on three objective criteria, and each one doubles as an authenticity check:
| Criterion | What genuine chips show | How fakes fail |
|---|---|---|
| Density | Higher-resin pieces sink or sit low in water | Light wood forced to sink via oil or embedded weights |
| Resin saturation | Irregular black-brown tiger-stripe veining | Uniform, even black surface from dye |
| Aromatic intensity | Fragrance builds and shifts under gentle heat | Strong smell cold, then vanishes when heated |
Higher resin content correlates with stronger fragrance, higher density, and a higher grade — so the three signals should agree. When a chip looks jet-black but barely smells on heat, the story does not add up.
Which physical tests actually work?
You do not need a lab. Four low-cost checks catch most fakes:
| Test | Method | Genuine result |
|---|---|---|
| Water immersion | Drop a chip in room-temperature water | High-resin pieces sink; grade tracks how fast |
| Hot-plate / steam | Warm a chip gently, do not burn it | Layered aroma that evolves over minutes |
| Scrape | Scratch the surface with a blade | Dye reveals a pale wood core; real resin runs deep |
| Burn | Ignite a sliver briefly | Clean, sweet smoke; no acrid chemical or plastic smell |
The scrape test is the fastest way to catch dye. Genuine resin penetrates the wood, so a fresh cut stays dark; surface dye shears off to show light wood underneath. On the hot plate, real agarwood releases a fragrance that opens, deepens, and mellows — sprayed fragrance oil tends to smell intense straight away and then disappear, because it never soaked into resin that was not there.
What are the biggest red flags of dyed or treated chips?
- A uniform, matte or glossy black with no visible grain or veining
- Colour that transfers to a damp white cloth or to your fingers
- An oily, greasy film or a solvent smell in the bag
- Chips that all sink identically regardless of size or shape
- A powerful cold aroma that collapses the moment heat is applied
- Suspiciously uniform sizes and shapes, hinting at pressed powder
- A “wild Super A” price on wood that shows none of the density or veining to match
Remember that grading systems are industry conventions that vary by region and tradition — they are not an official Indonesian national standard. A seller’s grade label is a starting point for negotiation, not proof.
How does price expose a fake?
Price is one of the loudest authenticity signals. As of 2026, plantation agarwood chips run roughly USD 500-7,000 per kilogram depending on grade (low-resin to super), and oud or agarwood oil runs about USD 30,000-80,000 per kilogram — figures that are indicative, with any final quote confirming grade and scope. Treat these as a grade-dependent band, not a single number.
At retail, buyer guides quote Indonesian chips near USD 5-15 per 10 g for low grade (C/D), USD 20-60 per 10 g for mid grade (B/A), and USD 100-300+ per 10 g for premium Super A, with natural oud oil at USD 200-1,000+ per ml. One common comparison lists wild A-grade chips at USD 50-120 per 10 g, cultivated B-grade chips at USD 20-40 per 10 g, and agarwood powder at USD 10-25 per 10 g. If a vendor offers “Super A” at powder prices, you are almost certainly looking at dyed or reconstituted material.
Does the paperwork tell you anything?
Yes — and it matters legally as well as for authenticity. Most Aquilaria and Gyrinops species are listed under CITES Appendix II, so international trade is regulated. Legal export requires a CITES export permit plus a BKSDA recommendation and is subject to a Non-Detriment Finding confirming trade will not harm wild populations; Indonesia’s 2024 NDF set a wild Aquilaria malaccensis quota of 24,110 kg. CITES paperwork also distinguishes source code W (wild) from P (plantation), and plantation material is generally easier to permit and more sustainable. Documented, plantation-sourced chips with a clear paper trail are far less likely to be the mystery batches that get dyed. This site is a sourcing broker and information hub, not a permit authority — always confirm current requirements with the CITES Management Authority (Indonesia) and your import country, and never accept a seller’s promise of guaranteed clearance as proof of quality.
Frequently Asked Questions
Can dyed agarwood chips still pass the water sink test?
Yes. Sinking only proves density, not authenticity. Fakers weigh light wood down by injecting it with heavy oils or embedding small weights, so treated chips sink convincingly. Always pair the water test with a scrape and a hot-plate aroma check — genuine resin runs deep and smells layered under gentle heat, while a doctored chip reveals pale wood and a thin, chemical scent.
Does a strong smell straight from the bag mean the chips are real?
No — often the opposite. Untreated agarwood is fairly subtle cold and only releases its full, evolving fragrance when gently heated. A powerful aroma at room temperature usually means the wood was sprayed or soaked in fragrance oil. Warm a sample: real chips deepen and shift over minutes, while scented fakes smell intense at first, then fade fast to almost nothing.
Is cheaper plantation agarwood automatically fake?
No. Plantation (cultivated) agarwood is completely legitimate and is generally easier to export legally, carrying CITES source code P. It is genuinely lower priced than rare wild material, which is honest pricing, not fraud. “Fake” refers to misrepresentation — dyed, oil-injected, or powder-pressed wood sold as premium grade. Judge a chip by its veining, density, and aroma, not by whether it was farmed or wild.
