How to Read Agarwood Appraisal Certificates: Institution, Tests, and Conclusion

The key to reading an agarwood appraisal certificate lies in three elements: the authority of the issuing institution, the relevance of the test items, and the rigor of the conclusion. A credible certificate should come from a professional body with CMA/CNAS accreditation, include key indicators such as tree species, alcohol-soluble extracts, and characteristic compounds, and avoid simply stating 'true' or 'false'. This article teaches you how to interpret each part of an agarwood certificate and avoid being misled.

1. Institution: Who Is Qualified to Issue an Agarwood Certificate?

The authority of an agarwood appraisal certificate first depends on the issuing institution. In China, legally valid testing institutions must be accredited by CMA (China Metrology Accreditation) or CNAS (China National Accreditation Service for Conformity Assessment). Common authoritative bodies include the Research Institute of Wood Industry under the Chinese Academy of Forestry, the Forest Products Quality Inspection and Testing Center of the National Forestry and Grassland Administration, and some provincial forest product quality inspection stations. If a certificate is only stamped by a non-testing organization such as an 'XX Fragrance Association' or 'XX Culture Research Society', its conclusion is for reference only and has no legal effect. Internationally, well-known organizations like SGS or CITES laboratories can also issue relevant reports, but note whether their testing standards apply to agarwood. When examining a certificate, first verify the institution's accreditation number and check its authenticity on the official website.

2. Test Items: Which Key Indicators Are Tested?

A professional agarwood certificate should list specific test items. Core items include: tree species identification (determining through wood anatomy whether it belongs to the Thymelaeaceae family, Aquilaria or Gyrinops genus), alcohol-soluble extract content (reflecting resin content, an important indicator of quality), characteristic chemical composition analysis (e.g., using gas chromatography-mass spectrometry to detect agarwood-specific compounds such as 2-(2-phenylethyl)chromones), and density or sinking test (to assist in judging resin accumulation). If a certificate merely states 'identified as agarwood by experts' without specific data and test methods, its credibility is low. For a detailed classification and interpretation of appraisal items, refer to our Identification Pillar Page, which systematically outlines the applicable scenarios of various testing methods.

3. Conclusion: Is the Statement Rigorous and Objective?

A formal certificate usually does not simply state 'true' or 'false', but provides a specific description. For example: 'The sample is Aquilaria sinensis of the Thymelaeaceae family, with an alcohol-soluble extract content of XX%, and characteristic agarwood compounds detected.' For kyara, the conclusion may read 'conforms to kyara characteristics' or 'kyara-specific compounds detected', but will not easily make a definitive judgment. It is important to note that no single test can 100% determine origin or whether it is wild, so conclusions are often 'supportive' or 'exclusionary'. If a certificate contains marketing language such as 'absolutely wild' or 'top-grade kyara', be cautious. To learn more about kyara identification standards, see the Kyara Pillar Page. In addition, agarwood identification combines traditional experience with modern science; the wisdom of Chinese incense studies can be found in the Chinese Incense Studies · Agarwood Identification section.

4. Common Traps and Verification Points

Forged or 'knock-off' certificates exist in the market. When verifying, pay attention to: whether the certificate number can be queried on the official website, whether the sample photo matches the actual item, whether the test date is reasonable, and whether the institution's seal is clear. Additionally, some certificates only provide 'material identification' without quality grading; consumers should distinguish between 'appraisal certificates' and 'grading certificates'. To systematically learn agarwood identification, it is recommended to start with the Agarwood Encyclopedia to build an overall cognitive framework.

Conclusion

The key to understanding an agarwood appraisal certificate is to recognize authoritative institutions, carefully read test items, and treat conclusions rationally. A certificate is an auxiliary tool, not the sole basis; combining sensory evaluation with professional learning will lead to more accurate judgment of agarwood value.
