Agarwood Identification and Standards: Evolution of Testing Methods and Grading Criteria

Agarwood identification is shifting from experience-driven to instrument-assisted analysis alongside standard-based grading, reshaping trust and trading rules in the industry.

Phenomenon: Diversified Testing Methods and Refined Grading Criteria

In recent years, agarwood identification has shown a trend of diversified testing methods and increasingly refined grading criteria. Feedback from production areas indicates that traditional sensory evaluation—visual inspection, aroma, and burning—remains widespread, but more practitioners and consumers are turning to instrumental analysis for auxiliary judgment. According to publicly available industry information, techniques such as gas chromatography-mass spectrometry, infrared spectroscopy, and high-performance liquid chromatography are being gradually introduced for authenticity and quality assessment, with some testing bodies establishing fingerprint libraries of characteristic agarwood compounds. Meanwhile, grading criteria are transitioning from relatively vague categories like “sinking, semi-sinking, non-sinking” and origin labels toward multi-dimensional indicators including oil content, density, aromatic characteristics, and microscopic structure. Industry group standards and local standards have been issued successively, providing clearer specifications for terminology, classification, and testing methods, though a unified national grading system is still being explored.

Cause Analysis: Technology Maturity, Market Expansion, and Standard Supply

Multiple drivers underlie this evolution. First, the maturation and cost reduction of analytical testing technologies have moved instrumental identification from laboratories to broader commercial applications, providing quantifiable bases for authenticity determination and quality grading. Second, the continued expansion of the agarwood market, with a growing consumer base and increased online transactions, demands greater information symmetry, pushing identification and grading toward transparency. Third, standard-supply entities—industry organizations and research institutions—are advancing standards for terminology, classification, and testing methods, laying the foundation for unified grading criteria. Additionally, the cultural dual attributes of agarwood as both traditional incense material and collectible prompt the market to seek balance between “experiential heritage” and “scientific quantification.” Feedback from production areas shows rising demand for distinguishing plantation from wild agarwood, further driving refinement of testing methods.

Implications for Practitioners and Consumers: Anchoring on Standards, Viewing Results Rationally

For practitioners, the evolution of testing methods and grading criteria means adjusting business logic. On one hand, pricing relying solely on experience or origin labels faces challenges; building traceable quality records and proactive testing will become means to enhance competitiveness. On the other hand, following standard developments and participating in standard promotion can help reduce disputes in transactions. For consumers, understanding the scope and limitations of testing methods is crucial—instrumental analysis can assist in authenticity checks, but aromatic experience and craftsmanship value still require comprehensive judgment. Refined grading criteria do not equate to absolute superiority or inferiority; consumers should view test reports rationally and avoid making single indicators the sole basis for decisions. At the industry level, standardization of testing and grading helps build trust mechanisms, but the perfection of a unified standard system still takes time.
