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

This article teaches you how to interpret agarwood authentication certificates: from the authority of the issuing institution, the completeness of test items, to the rigor of the conclusion, three steps to identify the value of a certificate and avoid being misled by invalid certificates.

1. Check the Institution: Who Issues the Certificate Determines Credibility

The first element of an agarwood authentication certificate is the issuing institution. In China, institutions that can issue agarwood certificates fall into three categories: national or provincial quality supervision and inspection institutes, forestry research institutes, and third-party commercial testing companies. Among them, institutions with CMA (China Metrology Accreditation) and CNAS (China National Accreditation Service) marks have legal validity and industry credibility. If the certificate only has an institution name without qualification marks, or the name is vague and unverifiable, the certificate's reference value is extremely low. It is advisable to verify the institution's qualification on the official website of the Certification and Accreditation Administration before viewing the certificate. For more basic knowledge about the agarwood identification system, please refer to the Identification Pillar Page.

2. Check the Test Items: Whether the Content Covers Key Indicators

A standard agarwood authentication certificate usually includes test items such as: wood species identification (to determine whether it is from the Thymelaeaceae family, Aquilaria genus), analysis of characteristic agarwood components (such as chromones), alcohol-soluble extract content, and whether it has been artificially treated (e.g., dyeing, oil injection, compression). If the certificate only states "agarwood" without specific test items and data, it is an invalid certificate. In particular, note that some certificates only perform "wood species identification," which can only prove the material is agarwood wood but cannot prove the quality and authenticity of the resin formation. A complete set of test items should answer two questions: "Is it agarwood?" and "What is the quality?" For detailed analysis of agarwood components and quality, please see the Agarwood Encyclopedia.

3. Check the Conclusion: Whether the Statement is Clear and Has Limiting Conditions

The conclusion part of the certificate is the most likely to be misleading. A standard conclusion should clearly state the test basis, test results, and final judgment, for example: "After testing, the sample is Aquilaria sinensis of the Thymelaeaceae family, contains characteristic agarwood components, and no artificial treatment traces were detected." If the conclusion only says "conforms to agarwood characteristics" without mentioning test methods and data, or uses vague wording such as "suspected" or "possible," it should be treated with caution. In addition, the certificate should indicate the sample number, test date, and tester to ensure traceability. For special varieties such as Kyara, the certificate conclusion should also indicate whether it meets the specific standards for Kyara.

4. Common Misconceptions and Key Points Summary

Misconception 1: Having a certificate means it is real agarwood. In fact, the certificate is only responsible for the submitted sample, and the testing capabilities of different institutions vary greatly. Misconception 2: The thicker the certificate, the more authoritative. The key lies in the test items and conclusion, not the number of pages. Misconception 3: Ignoring the certificate's validity period and sample correspondence. It is recommended to check whether the sample photo on the certificate matches the actual item when purchasing. Summary: Check institution qualification, test items, and conclusion statement—all three are indispensable. Mastering these methods, you can independently judge the value of an agarwood authentication certificate.
