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.
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.
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.
