HFC: phase-down starts 2028
  • HFC-32 is controlled by the Montreal Protocol (Annex F, group I): a hydrofluorocarbon (HFC) under the Kigali Amendment. India freezes HFC use in 2028 and cuts it in steps from 2032; there is no trade ban today.
  • 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.
