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
- Not listed by the Stockholm Convention (persistent pollutants), the Rotterdam Convention (prior consent before export) or the Montreal Protocol (ozone layer).
- Registered under EU REACH, so EU importers can buy it under an existing registration.
- Active on the US TSCA Inventory, so it can be imported into the US without a new-chemical notice.
- Listed on the Australian Inventory of Industrial Chemicals (AICIS), so it can be introduced into Australia as an existing industrial chemical.
- EU: harmonised classification as a reproductive toxicant category 1B (CLP Annex VI, index 005-005-00-1). It may not be sold to the general public in the EU as such or in mixtures above the limit (REACH Annex XVII, entries 28-30), and its use at work must be minimised.
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: 2931, other organo-inorganic compounds (e.g. organo-phosphorus, organo-silicon) (phosphorus, silicon or boron bonded to carbon).
- All lines under heading 2931 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.
