Specialty amines and ethanolamines: Regulation
Flammable, corrosive and sometimes sensitising: the hazards
What this tab covers How it is regulated and what could disrupt supply: hazard classification, rules in the EU, US and India, anti-dumping duties and other trade measures, and supply-risk notes.Hazards
| Classification | UN number | Key risks |
|---|---|---|
| flammable gas or liquid (methylamines, ethylamines); skin corrosion cat 1 (most amines); acute toxicity; EDA respiratory sensitiser | UN1061, UN1032, UN1235, UN2491, UN1604 | Corrosive and flammable; secondary amines can form carcinogenic nitrosamines, a concern for drug impurities and for amine-based carbon capture emissions. |
Main rules
| Where | Rule | Effect |
|---|---|---|
| EU | REACH restriction on DMF (from 12 Dec 2023) and NMP (from 2020) | cuts use of amine-derived solvents unless exposure limits are met |
| US and EU | Regulator limits on nitrosamine impurities in drugs (from 2018 onwards) | tighter purity specs for amines used in APIs |
| Global | Chemical Weapons Convention schedules for some ethanolamines (TEA, MDEA) | export reporting for triethanolamine and N-methyldiethanolamine |
India
| Rule | Effect |
|---|---|
| MSIHC Rules 1989 (methylamine listed as hazardous) | safety reporting and storage limits |
| Petroleum and Explosives Safety Organisation (PESO) rules for pressurised gas storage | licensing for anhydrous amine tanks |
| Chemical Weapons Convention Act 2000 reporting for scheduled chemicals such as TEA | export and production declarations |
Trade measures
- No current anti-dumping duty on major amines was found in the sources used (check DGTR)
Supply risk
Moderate. Products are made by few producers each, and India depends on imported methanol, ammonia and ethanolamines that pass through the Gulf. Not on critical lists.
