- 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 1B, mutagen category 1B (CLP Annex VI, index 613-001-00-1). 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 ₹27,730 duty on every ₹1,00,000 of import value (CIF).
