- 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.
- Listed on the Australian Inventory of Industrial Chemicals (AICIS), so it can be introduced into Australia as an existing industrial chemical.
Import dutyOK
- About ₹27,730 duty on every ₹1,00,000 of import value (CIF).
- Made up of basic customs duty 7.5%, social welfare surcharge 0.75% and IGST 18%. IGST can usually be claimed back as input tax credit.
