Import Tips
• Provide Certificates of Analysis (COA) confirming hexacyanoferrate composition to verify classification under 3206.49.55.00
• Label packages with pigment type, purity, and safety data sheets (SDS) for DOT and EPA compliance during import
• Avoid common pitfall of classifying as general inorganic pigment (3206.10); specify ferrocyanide/ferricyanide basis
