- Normal factory, storage and GST rules still apply.
Exporting from IndiaOK

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: 2934, nucleic acids and other heterocyclic compounds (ring containing S).
- All lines under heading 2934 pay basic customs duty 7.5%; with social welfare surcharge and IGST 18% that makes about 27.73%.
- No 8-digit line under heading 2934 names it, so it falls under one of its "Other" lines: 2934 92 00 (Other › Other fentanyls and their derivatives); 2934 99 90 (Other › Other). The other 7 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.
