How to Read Agarwood Authentication Certificates: Institution, Items, and Conclusion

This article explains how to interpret agarwood authentication certificates: from the authority of the institution, the scientific nature of test items, to the rigor of conclusion statements. Combined with Chinese incense appraisal knowledge, it helps you avoid certificate traps and rationally judge agarwood authenticity and quality.

1. Authentication Institution: Whose Certificate is Credible?

The first step in reading an agarwood certificate is to confirm the qualifications and credibility of the issuing institution. Currently, domestic agarwood testing institutions fall into three categories: national or provincial quality inspection institutes (such as NGTC, CQC), forestry research institutes (such as the Research Institute of Wood Industry, Chinese Academy of Forestry), and third-party commercial testing companies. Prioritize institutions with CMA (China Metrology Accreditation) or CNAS (China National Accreditation Service) marks, as such certificates have legal effect. Be wary of unqualified 'fly-by-night' institutions or overseas-registered 'international certifications' whose certificates often lack binding force. It is recommended to check the institution whitelist in the Agarwood Identification Pillar Page to avoid being misled by false endorsements.

2. Test Items: Which Indicators Truly Reflect Agarwood Quality?

Test items on a regular certificate usually include: tree species identification (whether it is from the Thymelaeaceae Aquilaria genus), oil content (alcohol-soluble extract), density (sinking or not), microscopic structure (vessels, rays, etc.), and characteristic components (such as 2-(2-phenylethyl)chromones). Among them, tree species identification is fundamental, while oil content and density are key to quality grading. However, note that a certificate is only responsible for the 'submitted sample', not the entire batch. If the certificate items only list subjective aspects like 'appearance' or 'odor', its reference value is limited.

3. Conclusion Statements: How to Understand the Results?

Certificate conclusions usually have three expressions: 'Conforms to agarwood characteristics', 'Agarwood components detected', or 'No agarwood components detected'. The first two indicate the sample is agarwood or contains agarwood components, but do not equate to 'natural wild' or 'high quality'. For example, 'conforms to agarwood characteristics' only means the tree species and basic structure are correct, not excluding artificial induction or compressed agarwood. If the conclusion is vague (such as 'suspected agarwood'), be cautious. In addition, the certificate should include sample photos, number, and test date, and its authenticity can be verified on the institution's official website. For special categories like Kyara, it is recommended to combine with the specific identification points in the Kyara Pillar Page for comprehensive judgment.

4. Common Traps and Countermeasures

Common market issues include: certificate swapping (genuine certificate with fake goods), expired certificates, and one-sided certificates that 'only identify tree species but not resin formation'. Countermeasures: check whether the certificate number matches the physical photo; request the merchant to provide a test report from the same batch as the actual product; for high-priced agarwood, send it to an authoritative institution for testing yourself. Meanwhile, learn basic identification knowledge from the Agarwood Encyclopedia to improve your own judgment and not blindly trust certificates.
