- Not on the US TSCA Inventory: EPA needs a premanufacture notice before it can be imported, unless it is a pesticide, drug or food additive, which TSCA does not cover.
- 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 reproductive toxicant category 1B (CLP Annex VI, index 613-140-00-8). 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).

- Basic customs duty 7.5% on every one of them; with social welfare surcharge and IGST 18% that makes about 27.73%.
- Lines that name a chemical are for that chemical; one that no line names goes under "Other" (2941 90 19, 2941 90 90).
