Import dutyOK

About 27.73% of the import value (estimate)
  • About ₹27,730 duty on every ₹1,00,000 of import value (CIF).
  • No tariff line names this chemical, so we worked out its likely heading from its structure: 2933, heterocyclic compounds with nitrogen hetero-atom(s) only (ring containing nitrogen).
  • 82 of 88 lines under heading 2933 pay basic customs duty 7.5%; with social welfare surcharge and IGST 18% that makes about 27.73%.
  • No 8-digit line under heading 2933 names it, so it falls under one of its "Other" lines: 2933 19 99 (Other › Other); 2933 29 90 (Other › Other); 2933 34 00 (Compounds containg an unfused pyridine ring (whether or not hydrogenated) in the); 2933 39 29 (Derivatives of pyridine › Other); 2933 39 90 (Other › Other); and 6 more. The other 77 lines are for named chemicals; which "Other" line applies depends on the exact structure.
  • Confirm the exact 8-digit code with your customs broker before you import.
