Every answer, with its source
Rules in IndiaOK
- Not on the Indian banned-pesticide, drug-precursor, narcotic, psychotropic or new-drug lists we check.
- On India’s hazardous chemicals list (MSIHC Rules 1989). Importers must send the State authorities the consignment details and full safety information before each import (30 days ahead where possible, never later than the import date) and keep import records.
Exporting from IndiaOK
- Not on the SCOMET export-control list or the precursor export list.
- Not approved as a pesticide in the EU: food sent there must carry almost none of it.
- The buyer’s country may still have its own import rules.
Global treaties & export marketsOK
- Not listed by the Stockholm Convention (persistent pollutants), the Rotterdam Convention (prior consent before export) or the Montreal Protocol (ozone layer).
- 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.
- Active on the US TSCA Inventory, so it can be imported into the US without a new-chemical notice.
- EU: harmonised classification (CLP Annex VI, index 017-026-00-3): Press. Gas, Ox. Gas 1, Acute Tox. 2, Skin Corr. 1B, Aquatic Acute 1. Suppliers in the EU must label it this way.
- EU: harmonised classification (CLP Annex VI, index 017-026-01-0): Acute Tox. 3, Skin Corr. 1B, Aquatic Acute 1. Suppliers in the EU must label it this way.
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 name: 2811, other inorganic acids and inorganic oxygen compounds of non-metals (named compound).
- All lines under heading 2811 pay basic customs duty 7.5%; with social welfare surcharge and IGST 18% that makes about 27.73%.
- Confirm the exact 8-digit code with your customs broker before you import.
SafetyNO DATA
- No classification does not mean it is safe.
- Always read the supplier’s safety data sheet (SDS) before handling.
Food residue limitsCHECK
- India (FSSAI) has no specific limit, so the default 0.01 mg/kg applies to food.
- EU: not approved; most EU food limits are at the detection limit.
Price and suppliersNO DATA
- Post a requirement and we will find suppliers for you.
