  • Holding 5 t or more on one site brings the major-accident rules (notify the site, safety audits, emergency plans); 50t or more also needs a safety report.

Exporting from IndiaOK

No export licence needed
  • Not on the SCOMET export-control list or the precursor export list.

Global treaties & export marketsOK

No treaty or export-market restriction found
  • 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 (CLP Annex VI, index 016-001-00-4): Flam. Gas 1A, Press. Gas, Acute Tox. 2, Aquatic Acute 1. Suppliers in the EU must label it this way.

Import dutyOK

About 27.73% of the import value (estimate)
  • 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: 2830, sulphides; polysulphides (sulphide).
  • All lines under heading 2830 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.

  • Fatal if inhaled
  • Very toxic to aquatic life
  • Always read the supplier’s safety data sheet (SDS) before handling.

Storage, transport & PESOCHECK

PESO licence needed
  • A gas under pressure: filling, storing or transporting it in cylinders needs PESO approval, and large storage tanks need a licence under the SMPV(U) Rules.
  • Ships as UN 1053 / UN 1228 / UN 2448 (Poison Gas Flammable Gas): dangerous-goods rules apply by road, sea (IMDG) and air (IATA), with labels, packaging and a transport document.
