Import dutyOK

About 24.49% of the import value (estimate)
  • About ₹24,490 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: 2904, sulphonated, nitrated or nitrosated derivatives of hydrocarbons (nitro, nitroso or sulphonic acid group).
  • All lines under heading 2904 pay basic customs duty 5%; with social welfare surcharge and IGST 18% that makes about 24.49%.
  • No 8-digit line under heading 2904 names it, so it falls under one of its "Other" lines: 2904 10 90 (Derivatives containing only sulpho groups, their salts and ethyl esters › Other); 2904 20 90 (Derivatives containing only nitro or only nitroso groups › Other); 2904 35 00 (Perfluorooctane sulphonic acid, its salts and perfluorooctane sulphonyl fluoride); 2904 99 90 (Other › Other). The other 22 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.
