Fake Agarwood: How to Spot Treated Chips, Beads and Carvings Before You Buy

Fake agarwood is any material sold as resinated Aquilaria wood when its colour, scent or weight did not come from the tree's own resin. It ranges from plain wood dressed up to look dark, to real low-grade agarwood dressed up to look like a higher grade.

One measurable benchmark does exist. According to Liu et al. (2013), the Chinese Pharmacopoeia requires no less than 10% alcohol-soluble extractive in agarwood; induced samples in the study reached 11.60–18.08%, while two wild samples scored 10.56% and 19.30%.^[7]

Genuine agarwood forms when an Aquilaria tree responds to wounding and infection by filling damaged tissue with aromatic resin. That resin is a complex mix dominated by sesquiterpenes and 2-(2-phenylethyl)chromones.^[1] No soak, dye or glue reproduces that chemistry inside the wood.

The incentive to fake is simple. Agarwood is among the most expensive natural raw materials in the incense and fragrance trade, and the price climbs steeply with resin content.^[2] Therefore a fake does not need to be perfect; it only needs to move a piece up one or two grades.

Treated Is Not Always Fake

Not every treated product is a fraud. Bakhoor, for example, is wood chips soaked or blended with oils and aromatics on purpose, and buyers know it. Our own bakhoor incense chips are sold as exactly that, not as natural oud.

The line is the label. A treated product sold as treated is a legitimate item with its own price. However, the same chip sold as natural "Grade A oud wood" becomes fake agarwood, because the buyer is paying for resin that is not there.

We see the problem from the supply side. Our founder grades every lot of our plantation chips by look, aroma, resin content and the sink test, and we know how real resin behaves under each test. That is the knowledge we share in this guide, so you can apply the same checks to any supplier, including us.

You spot fake agarwood chips by checking four things in order: grain, cold smell, behaviour under low heat, and what the inside looks like. A genuine chip stays consistent across all four, while a treated chip usually fails at least one.

These are the same broad criteria that grading literature describes for agarwood: appearance, aroma, resin content and density.^[3] At our grading table in Dian Bai we use visual inspection, aroma, resin content and the sink test for the same reason. No single check is enough on its own.

Look at the Grain, Not the Colour

Real resin follows the structure of the wood. Under good light and a 10× loupe, you see dark streaks and patches running along the grain, mixed with brown transition zones and some pale, unreacted wood.

Dye behaves differently. It tends to colour the whole surface evenly, gathers in cracks and end grain, and often looks flat rather than layered. Moreover, a piece that is black everywhere, with no gradient at all, deserves a closer look rather than a higher price.

Plantation chips in particular rarely look uniform. On our table we see resin lines, patches and pale areas side by side, even in good grades. A lot where every chip looks identical is unusual for natural material.

Smell It Cold Before You Heat It

Most genuine agarwood smells quiet at room temperature. You may notice a soft woody, slightly sweet or resinous note close to the nose, but the full aroma only appears with heat.

Fragrance-soaked fakes often reverse this. They smell loud and perfumy straight out of the bag, sometimes with a sharp, alcoholic or sugary edge. If a sealed bag fills the room before you open it, ask why.

A simple extra check is the paper wrap. Leave a few chips folded in plain white paper overnight. Oily stains or a strong transferred scent suggest the surface carries added oil rather than resin locked inside the wood.

The Low-Heat Test

Heat tells you more than any other quick test. Place a small sliver on an electric heater at a low setting, or on a mica plate over charcoal, and let it warm slowly rather than burn.

A genuine piece releases its scent gradually. The aroma changes over several minutes, moving through sweet, woody and deeper resinous notes, and the smoke stays thin and pale. Our guide to burning oud wood chips covers heater settings in more detail.

Fakes tend to give the game away early. Added fragrance often flashes off in the first minute, then leaves a flat, burnt-wood smell. Furthermore, dyes, lacquers and some fillers can produce dark, sooty smoke, a chemical note or a sticky residue on the plate.

Scrape, Split and Wipe

Surface treatments rarely go all the way through. With the seller's agreement, split one sample chip or scrape a fresh face with a clean blade. Real resin continues inside in the same pattern you saw outside.

A dyed chip often shows a pale core under a dark skin. Similarly, a soaked chip may smell strongly on the outside and weakly on the freshly cut face, which is the opposite of what natural resin does.

Finally, wipe a chip with a cotton swab dampened with alcohol, then with water. Colour that transfers to the swab points to dye or stain. Natural resin can leave a faint brownish trace, so compare against a reference piece rather than judging the swab alone.

Fake Agarwood Incense and Price Red Flags

Sticks and cones are easy to fake because the agarwood is ground up. A strong perfume smell before lighting, harsh or acrid smoke and heavy, oily ash all suggest added fragrance rather than real agarwood powder.

Price helps in one direction only. A price far below the market for the stated grade is a warning sign, but a high price proves nothing. If a retail purchase turns out to be fake, keep the packaging, receipt and photos, and use the seller's or marketplace's dispute process promptly.

No. The sink test proves that a piece is denser than water, not that the density comes from agarwood resin. It is a useful grading tool, but it is one of the easiest checks to fool.

• What it shows: resin is denser than pale Aquilaria wood, so heavily resinated pieces can sink. That is the origin of the Chinese "sinking" grade (沉水).
• What it misses: weighted fillers, some dense substitute woods and waterlogged material can sink too. A sinking piece can still smell poor on the heater.
• How to use it: combine it with the grain, cold-smell and heat checks above. A piece that sinks but smells weak when heated is a red flag, not a bargain.
• Grade label: on our D, C, B, A, AAA scale, many AAA pieces sink, but sinking alone does not make a piece AAA.

We explain how to run the test properly, and what results mean, in our guide to sinking agarwood.

Beads and carvings are where fake agarwood is hardest to catch, because you cannot cut a finished bracelet or sculpture to look inside. Therefore you rely more on grain, weight, consistency and the seller's documents.

Finished pieces also carry a higher price per gram than chips. For example, our bracelets are priced by weight from $18/g and carvings start from $98 per piece, so even a small upgrade in claimed grade changes the invoice a great deal.

Beads and Bracelets

Start with the grain. A bead turned from solid agarwood shows the same streaks and patches as a chip, and no two beads on a strand look exactly alike. A strand of perfectly matched, evenly dark beads is more typical of pressed powder or dye.

Next, look at the drill holes with a loupe. Solid wood shows grain running through the hole, and the hole edge stays crisp. Pressed composites often show a granular or glossy, uniform texture inside, and dye may be paler deep inside the hole than on the surface.

Smell matters as well. A genuine bead smells soft and warms up slowly against the skin. A bead that smells loudly of perfume on day one and faintly a week later was probably soaked. Our round-bead multi-wrap agarwood bracelet page shows how natural grain looks on a finished strand.

Carvings and Display Pieces

Carvings invite surface tricks. A sculpture can be carved from plain or low-grade wood and then stained, waxed or lacquered so the whole piece reads as dark resin.

Check the hidden surfaces first. Undersides, deep recesses and the base are harder to treat evenly, so colour differences often show there. In addition, look for soft, glossy filler in cracks and insect holes, and for glue lines where dark pieces join pale ones.

Ask how the piece was finished. Some carvers apply a light oil or wax for protection, which is normal if disclosed. However, a heavy coating that hides the grain makes grading impossible, and a reputable seller should say what was applied. Our agarwood carvings collection lists carvings by grade and size so buyers can compare like with like.

Fake oud oil is a separate problem from fake agarwood wood, and it needs separate tests. The usual issues are dilution with carrier oils, extension with cheaper materials, and synthetic "oud" fragrance sold as natural oil.

Quick checks such as a blotter test and evaporation over a day can raise flags. However, for a confident answer on oil, lab analysis matters more than for wood. Gas chromatography–mass spectrometry (GC-MS) separates and identifies the volatile compounds in a sample, so it can show whether the typical agarwood markers are present.^[4]

We provide GC-MS reports on request for our oils, including our hydro-distilled oud oil, which starts from $7.00/g with a 10 g MOQ. For the full bench protocol, adulterants and red flags, read our pure oud oil testing guide. Here we keep the focus on wood.

Is My Oud Perfume Original?

Shoppers often ask whether an oud perfume is original. Two different questions hide in that phrase. One is whether the bottle is a genuine product of the brand on the label, which only the brand or an authorised seller can confirm. The other is whether the perfume contains real agarwood oil at all.

Most mainstream oud perfumes use an oud accord built from aroma chemicals, sometimes with a small amount of natural oil. That is legal and normal. If real agarwood content matters to you, ask the seller for the percentage of natural agarwood oil and, for oils sold as pure, a GC-MS report.

All Aquilaria species have been listed in CITES Appendix II since 2004, so international trade in wood and many products needs export documents where required.^[5] Annotation #14 exempts some finished, retail-packaged products, so check the current annotation text for your exact product.

A permit does not grade the wood. Nevertheless, a supplier willing to name the species on official paper is easier to hold to account than one who cannot. Trade studies have long noted how many grades and trade names circulate in agarwood markets, which is exactly why written descriptions matter.^[6]

Every wholesale shipment from us travels with a grading note or certificate and a CITES Appendix II export permit where required. Our CITES permit walkthrough explains the paperwork step by step, and our agarwood grading guide explains how the D to AAA scale works. That scale is our own internal system, not an ISO or CITES standard.
