Import dutyOK
- 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: 2932, heterocyclic compounds with oxygen hetero-atom(s) only (ring containing oxygen).
- All lines under heading 2932 pay basic customs duty 7.5%; with social welfare surcharge and IGST 18% that makes about 27.73%.
- No 8-digit line under heading 2932 names it, so it falls under one of its "Other" lines: 2932 19 90 (Other › Other); 2932 20 90 (Lactones › Other); 2932 99 90 (Other › Other). The other 15 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.
SafetyOK
- Always read the supplier’s safety data sheet (SDS) before handling.
