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

The credibility of an agarwood authentication certificate depends on the qualifications of the issuing institution, the completeness of test items, and the rigor of the conclusion. This article teaches you to quickly judge a certificate's value from three dimensions: institution, test items, and conclusion, avoiding misleading invalid certificates.

1. Institution: Who issues the certificate determines its baseline

The first thing to check is the issuing institution. Authoritative institutions usually have CMA (China Inspection Body and Laboratory Mandatory Approval) or CNAS (China National Accreditation Service for Conformity Assessment) qualifications and have long focused on wood or aromatic material testing. If the certificate comes from an unknown association, cultural company, or non-testing entity like 'XX Agarwood Research Institute', its conclusion is for reference only and cannot be used as a basis for transactions. It is advisable to prioritize certificates issued by provincial or higher forestry academies, customs technical centers, or professional aromatic material testing laboratories. When examining the institution, you can compare it with the list of compliant institutions in the Identification Pillar Page.

2. Test items: What was tested matters more than the conclusion

Test items on a formal agarwood certificate typically include: species identification (e.g., Aquilaria of Thymelaeaceae), whether artificially treated (dyed, oil-injected, high-pressure, etc.), density (sinking or not), alcohol-soluble extract content, etc. If the certificate only says 'agarwood' without specific test items and data, it is a 'qualitative certificate' with limited reference value. Pay special attention to whether the certificate includes key items such as 'non-destructive testing' or 'microscopic observation'. For special categories like kyara, also check whether slice analysis or component spectrum comparison was performed; for details, refer to the identification points in the Kyara Pillar Page.

3. Conclusion: Rigor of wording determines credibility

The conclusion should clearly state 'conforms to agarwood characteristics' or 'Thymelaeaceae Aquilaria components detected', rather than vague phrases like 'suspected agarwood' or 'has agarwood characteristics'. If the conclusion includes 'further testing recommended', it means the certificate has not given a final judgment. In addition, the certificate number, test date, tester's signature, and institution seal are indispensable. Consumers can verify the authenticity of the certificate through the institution's official website or phone. For more interpretation of certificate conclusions, see the case analysis in the Chinese Incense Studies · Agarwood Identification special topic.

In short, an effective agarwood authentication certificate should have: a qualified institution, test items with data, and a conclusion with basis. All three are indispensable; never place an order based solely on the certificate cover or 'authenticity guaranteed' wording.
