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

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

Phenomenon: Diversified Testing Methods and Parallel Grading Criteria

In recent years, agarwood authentication has shown a clear trend of diversified testing methods running parallel with multiple grading criteria. Feedback from production regions indicates that traditional sensory-based authentication—looking, smelling, touching, and water-sinking tests—remains widespread, but more practitioners are introducing instrumental analysis such as gas chromatography-mass spectrometry, infrared spectroscopy, and microscopic structure observation to assist in judging authenticity, origin, and quality. Meanwhile, grading criteria have not formed a unified industry-wide standard. Terms such as "sinking grade," "semi-sinking grade," and "floating grade" are used differently across institutions, production areas, and trading scenarios. Some markets are beginning to use quantifiable indicators such as oil content, density, and aroma characteristics as grading references. According to publicly available industry information, the enrichment of testing methods and the dispersion of grading criteria constitute the basic landscape of agarwood authentication today.

Cause Analysis: Technology, Demand Differentiation, and Standard Lag

Multiple factors contribute to this phenomenon. First, technology is a core driver. Falling costs of instrumental analysis and the emergence of portable devices have enabled more practitioners to access and use testing methods, pushing authentication from pure experience toward experience plus data. Second, market demand is clearly differentiated. High-end collectors and daily consumers have different requirements for authentication accuracy—the former relies more on authoritative testing and grading endorsement, while the latter focuses on cost-effectiveness and basic authenticity—making unified grading criteria difficult. Third, standard development lags behind market growth. Agarwood involves multiple variables including tree species, origin, resin formation method, and processing techniques. Developing unified standards requires interdisciplinary collaboration and extensive sample accumulation. Currently, industry standards, group standards, and local standards coexist, and a consensus grading system covering the entire chain has not yet formed. In addition, cultural cognitive differences affect acceptance of grading criteria; different markets prefer different aroma types, making full objectification of grading standards challenging.

Implications for Practitioners and Consumers: Embrace Testing, Understand Grading, Watch Standards

For practitioners, the evolution of testing methods means authentication capabilities need to upgrade from single experience to composite skills. It is advisable to understand the principles and limitations of mainstream testing methods, use test reports appropriately as support in transactions, and avoid over-reliance on single indicators. The dispersion of grading criteria requires practitioners to clarify the grading basis used in communication to reduce disputes caused by terminology ambiguity. For consumers, understanding the diversity of testing methods helps establish reasonable authentication expectations and avoid blind faith in single test conclusions; understanding differences in grading criteria helps focus on specific indicators rather than just grade labels when purchasing. At the industry level, standard development is still in progress, and both practitioners and consumers can follow relevant standard developments and participate in forming industry consensus.
