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

To read an agarwood certificate, check three things: institution qualification (CMA/CNAS), test items (species, origin, oil content, etc.), and conclusion wording (natural/artificial, grade). This guide provides practical interpretation to avoid misreading.

1. Institution: Qualification and Authority Determine Validity

The issuing institution is the first checkpoint for judging an agarwood certificate's credibility. In China, a legitimate testing institution should carry the CMA (China Inspection Body and Laboratory Mandatory Approval) mark, and some authoritative bodies also have CNAS (China National Accreditation Service for Conformity Assessment) accreditation. The certificate should clearly state the institution's name, address, qualification number, and verification method. If there is no CMA mark or the institution name is vague, the certificate has no legal effect and can only be for reference. Additionally, some industry-specific research institutes or associations issue technical certificates, whose credibility should be evaluated comprehensively. It is advisable to prioritize third-party testing institutions with both CMA and CNAS qualifications, or refer to the list of common authoritative institutions in the Identification Pillar Page.

2. Items: Whether the Test Covers Key Indicators

A formal agarwood certificate lists test items, commonly including: species identification (whether it belongs to the Aquilaria genus of Thymelaeaceae), origin analysis (via composition or isotopes), oil content (alcohol-soluble extract), characteristic component content such as agarotetrol, and detection of artificial additives (e.g., pitch, rosin, chemical fragrances). If the certificate only states "agarwood" without specific items, the information is insufficient. For special categories like Kyara, attention should be paid to whether characteristic component analysis is included; refer to the Kyara Pillar Page for key identification points. Consumers should check whether the certificate items match the product claims; for example, if "Hainan wild" is claimed but the certificate lacks origin identification, the conclusion is insufficiently supported.

3. Conclusion: Wording and Grade Determination

The conclusion section usually gives judgments such as "conforms," "detected," or "not detected." Note that the conclusion may only apply to the submitted sample, not the entire batch; the terms "natural agarwood" and "artificial agarwood" must have clear evidence (e.g., whether artificial fragrance components are detected); grade determination (e.g., special grade, first grade) should be accompanied by a standard number if based on institutional standards. In addition, the certificate should bear signatures of the tester, reviewer, and approver, as well as the test date, and its authenticity can be verified via the institution's website or phone. If the conclusion is vague or lacks key information, treat it with caution. For more identification details, see the Chinese Fragrance Studies · Agarwood Identification topic, or systematically study the certificate interpretation chapter in the Agarwood Encyclopedia.

4. Key Points and Conclusion

Reading an agarwood certificate can be summarized as "three checks": first, institution qualification (CMA/CNAS); second, item coverage (species, origin, composition, additives); third, conclusion wording (scope, basis, signatures). A certificate is an auxiliary tool and should be combined with sensory evaluation of the actual product and market common sense. When purchasing, ask for the original or a clear copy of the certificate and keep transaction records. Mastering these methods will help avoid being misled by false certificates.
