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.
- Holding 100 kg or more on one site brings the major-accident rules (notify the site, safety audits, emergency plans).
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 marketsOK
- 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 015-181-00-1): Flam. Gas 1, Press. Gas, Acute Tox. 1, 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: 2850, hydrides, nitrides, azides, silicides and borides (named compound).
- All lines under heading 2850 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.
SafetySTOP
- Catches fire easily
- Gas under pressure

- Causes severe skin burns and eye damage
- Fatal if inhaled
- Very toxic to aquatic life
- Always read the supplier’s safety data sheet (SDS) before handling.
Storage, transport & PESOCHECK
- 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 2199 / UN 3525 (Poison Gas Flammable Gas): dangerous-goods rules apply by road, sea (IMDG) and air (IATA), with labels, packaging and a transport document.
Food residue limitsOK
- India (FSSAI) has no specific limit, so the default 0.01 mg/kg applies to food.
- EU: approved as a pesticide.
