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.
- 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 carcinogen category 1A, mutagen category 1B (CLP Annex VI, index 601-013-00-X). 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 ₹21,240 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: 2901, acyclic hydrocarbons (hydrocarbon).
- All lines under heading 2901 pay basic customs duty 2.5%; with social welfare surcharge and IGST 18% that makes about 21.24%.
- Confirm the exact 8-digit code with your customs broker before you import.

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 1010 (Flammable Gas): dangerous-goods rules apply by road, sea (IMDG) and air (IATA), with labels, packaging and a transport document.
