CN code 320300 covers colouring matter of vegetable or animal origin, including dyeing extracts, as well as preparations based thereon. This includes natural indigo, cochineal dyes (carmine, carminic acid), curcumins, sandalwood dyes, lawsone (henna), and other natural pigments and dyes. These products find application in the textile, food, cosmetic, and pharmaceutical industries. Classification requires confirmation of the natural origin of the colouring substance, as synthetic equivalents are classified under other headings of Chapter 32. Preparations based on natural colouring matter also fall under this heading.

Import of natural colouring matter into the EU is subject to the REACH Regulation. These substances must be registered with ECHA, and the importer is required to hold an SDS. Dyes used as food additives are subject to additional requirements under Regulation (EC) No 1333/2008 on food additives and must have EFSA authorisation. Dyes for cosmetics are subject to Regulation (EC) No 1223/2009 on cosmetic products and must be listed in Annex IV. CLP labelling is required for all commercial forms. Some natural dyes may be contact allergens, requiring appropriate warning labels. Products from cochineal may be subject to CITES provisions.

When clearing colouring matter under CN code 320300, documentation confirming natural origin, chemical specification, and intended product use must be presented. For food-grade dyes, a health certificate and compliance with food safety requirements are necessary. CITES-listed dyes require an import permit. Tariff preferences are available under EU trade agreements, including the GSP system for developing countries. Export of natural colouring matter is not subject to special export restrictions unless the product is classified as a dual-use good. Verification in the TARIC database is recommended before each transaction.

When importing Colouring matter of vegetable or animal origin (CN 3203 00) into the EU, VOC content regulations under Directive 2004/42/EC must be considered. Decorative paints and automotive refinish products have established VOC limits. CLP classification requires appropriate GHS pictogram labelling on packaging. Pigments containing heavy metals (lead, cadmium, chromium VI) are subject to strict REACH restrictions (Annex XVII). Importers must have SDS sheets and ensure labelling complies with destination country regulations.
