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

To read an agarwood certificate, focus on three aspects: whether the issuing institution has CMA/CNAS accreditation, whether test items cover key indicators (e.g., ethanol extract content, agarotetrol), and whether the conclusion clearly distinguishes natural agarwood from artificially treated wood. This article provides a step-by-step guide to help you quickly assess certificate credibility.

1. Institution: Qualifications and Authority

The issuing institution is the primary criterion. A legitimate institution should hold CMA (China Inspection Body and Laboratory Mandatory Approval) or CNAS (China National Accreditation Service for Conformity Assessment) accreditation, and the certificate number should be verifiable online. Be wary of unqualified or vaguely named 'associations' or 'centers'. It is advisable to prioritize laboratories recognized in forestry, pharmaceutical, or agarwood research fields. For more on institution verification, see the Identification Pillar Page.

2. Test Items: Comprehensiveness of Indicators

Test items reflect the depth of authentication. Common items include sensory evaluation (appearance, aroma), microscopic identification, thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC) for agarotetrol, and ethanol extract content. A high-quality certificate specifies test methods and result data, not just 'compliant'. If key chemical indicators are missing, the conclusion's credibility is limited. For deeper understanding of testing standards, refer to Chinese Agarwood Studies · Identification.

3. Conclusion: Clarity and Rigor

The conclusion should clearly determine whether the sample is natural agarwood and whether it has been artificially treated (e.g., dyeing, oil injection, high pressure). Vague statements like 'suspected agarwood' or 'possesses agarwood characteristics' require caution. Also, ensure the certificate corresponds to the actual item (photo, weight, number) to avoid certificate swapping. If the conclusion is 'natural agarwood', supporting data should be attached. For terminology, see the Agarwood Encyclopedia.

4. Additional Points

A certificate is not the sole basis; combine it with physical observation and experience. For high-value agarwood (e.g., kyara), obtain reports from multiple institutions for cross-verification. Kyara identification has its particularities; refer to the Kyara Pillar Page.

In short, when reading a certificate, check three things: institution qualifications, test items, and conclusion wording. Only when all three are satisfactory does the certificate have reference value.
