Distilled Cardanol from Cashew Nut Shell Liquid
Distilled cardanol is a refined fraction of cashew nut shell liquid, primarily containing meta-substituted alkyl phenols derived from anacardic acid decarboxylation. It serves as a key bio-based monomer for resins and coatings. Still classified under HTS 1302.19.91.20 when imported as cashew nut shell liquid derivative without full chemical transformation.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If further purified to >95% cardanol as industrial-grade phenolic compound
High-purity cardanol meeting chemical specification thresholds moves to Chapter 29 as phenols, separate from crude vegetable extracts.
If blended with solvents or additives for direct industrial application
Prepared chemical mixtures for specific uses like paints fall under Chapter 38 as chemical preparations rather than extracts.
If heavily processed into natural gum substitutes
Advanced modification resembling natural rubber gums would shift to Chapter 40, though rare for CNSL.

Import Tips & Compliance
• Require supplier distillation specs showing vacuum distillation process without synthetic additives
• Label clearly as 'distilled CNSL' to avoid misclassification as pure chemicals
• Test for residual anacardic acid levels to confirm processing stage

Raw Cashew Nut Shell Liquid (CNSL)
Raw cashew nut shell liquid is a natural vegetable extract obtained from the pericarp of cashew nuts during processing. It consists primarily of phenolic compounds like anacardic acid, cardanol, and cardol, making it a versatile industrial raw material. Classified under HTS 1302.19.91.20 as a specific type of other vegetable sap or extract.
Technical Grade Cashew Nut Shell Extract (CNSL 60%)
Technical grade CNSL extract contains approximately 60% phenolic content from cashew nut shells, standardized for industrial use in friction materials and paints. It remains a direct vegetable sap/extract without exclusionary additives like sugars or medicaments. HTS 1302.19.91.20 specifically covers this cashew-derived product.
Decarboxylated Cashew Nut Shell Liquid for Resins
Decarboxylated CNSL undergoes heating to convert anacardic acids to cardanols, yielding a stable extract for phenolic resin production. This semi-processed form retains its identity as cashew nut shell liquid extract. Falls squarely under HTS 1302.19.91.20 as specified vegetable extract.
