How to Identify Agarwood — Sample Assessment and Method Limits

Tell us what needs to be established before sending material: a sensory comparison, botanical identification, a specified adulterant question or a commercial grade opinion. These are different questions and may require different methods. A photograph or a pleasant scent is not enough to resolve them all.

A sensory assessment records the sample’s observed character against stated references. It is not a measured resin percentage, proof of species, geographic origin, wild source or an objective kyara classification.

GC-MS can examine compounds covered by an appropriate preparation and analytical method. It may help investigate specified substitutions or adulterants, but does not automatically identify every carrier, synthetic reconstruction or dilution. Detection limits, reference material, sample preparation and interpretation must be stated.

Distilled oil and a solvent or CO₂ extract need different interpretation. Do not assume a routine volatile profile quantifies all resin constituents or chromones. The absence or presence of a selected peak is not, on its own, proof of botanical identity, grade or authenticity.

For independent work, agree the laboratory, method, sample amount, identification, report scope, cost and timing in advance. Confirm any relevant accreditation and its actual scope rather than implying that every arranged analysis carries blanket accreditation.

The laboratory report should identify the submitted sample and the work performed. We can help read its stated findings and limitations. No report establishes the condition of untested material simply because it shares a trade name or supplier.

A retained portion, lot markings and dated photographs can support sample traceability. They do not turn a nonrepresentative sample into proof of an entire lot. Agree any representative sampling and chain-of-custody procedure before testing if that distinction matters.

Material from another supplier can be considered, with their paperwork supplied for context. We do not publish an unsupported percentage or share of samples that are misdescribed. An unfavourable result must be explained against the actual method rather than a presumption about the seller.

Our commercial grading opinion is not legally binding and is not a substitute for legal, insurance or regulatory advice. Whether any report is suitable evidence for a dispute is for the relevant adviser or authority to determine.

Confirm the amount and shipping requirements with the selected laboratory before dispatch. The sample minimum for purchasing our oil remains 5 g; analytical sample requirements are a separate matter. Completion dates depend on the method and laboratory schedule rather than a universal five-to-eight-day promise.
