Import dutyOK

About 27.73% of the import value (depends on the line)
  • About ₹27,730 duty on every ₹1,00,000 of import value (CIF). Some lines under this subheading pay a different rate.
  • The EU customs inventory (ECICS) classifies it under CN 3204 12 00, so its HS subheading is 3204 12.
  • India splits subheading 3204 12 into 47 lines: 3204 12 11 (Azo dyes › Acid yellows), duty 10%; 3204 12 12 (Azo dyes › Acid oranges); 3204 12 13 (Azo dyes › Acid red); 3204 12 14 (Azo dyes › Acid violets); 3204 12 15 (Azo dyes › Acid blues); 3204 12 16 (Azo dyes › Acid greens); and 41 more.
  • Basic customs duty 7.5% on 43 of them; with social welfare surcharge and IGST 18% that makes about 27.73%.
  • Lines that name a chemical are for that chemical; one that no line names goes under "Other" (3204 12 19, 3204 12 29, 3204 12 39).
  • Confirm the exact 8-digit line with your customs broker before you import.
