Rules in IndiaOK
- Not on the Indian banned-pesticide, drug-precursor, narcotic, psychotropic or new-drug lists we check.
- Normal factory, storage and GST rules still apply.
Exporting from IndiaOK
- Not on the SCOMET export-control list or the precursor export list.
- The buyer’s country may still have its own import rules.
Global treaties & export marketsCHECK
- Its structure (a perfluorooctane sulfonyl group (C8F17SO2)) fits the Stockholm Convention listing “Perfluorooctane sulfonic acid (PFOS), its salts and perfluorooctane sulfonyl fluoride (PFOSF)” (Annex B): production and use are restricted worldwide to the purposes the treaty allows.
- Its structure (a perfluorooctane sulfonyl group (C8F17SO2)) falls under the Rotterdam Convention prior-consent entry “Perfluorooctane sulfonic acid, perfluorooctane sulfonates, perfluorooctane sulfonamides and perfluorooctane sulfonyls”.
- Each importing country has said whether it accepts this chemical; an export must follow that decision. Check the country’s import response on pic.int before you ship.
- No EU REACH registration found: an EU importer (or your only representative) must register it before importing a tonne or more a year. Medicines and pesticide actives follow their own EU rules.
- Not on the US TSCA Inventory: EPA needs a premanufacture notice before it can be imported, unless it is a pesticide, drug or food additive, which TSCA does not cover.
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: 2935, sulphonamides (sulphonamide group).
- All lines under heading 2935 pay basic customs duty 7.5%; with social welfare surcharge and IGST 18% that makes about 27.73%.
- No 8-digit line under heading 2935 names it, so it falls under one of its "Other" lines: 2935 50 90 (Other perfluorooctane sulphonamides › Other); 2935 90 90 (Other › Other). The other 14 lines are for named chemicals; which "Other" line applies depends on the exact structure.
