Nylon (PA6, PA66): Regulation

Nitrous oxide, cyanide and EU carbon pricing

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
polymer not classified; caprolactam irritant; HMDA corrosive (skin corrosion category 1B)	not regulated (polymer)	Upstream hydrogen cyanide (ADN) and nitric acid oxidation (adipic acid) carry major-hazard risk; adipic acid emits N2O.

Main rules

Where	Rule	Effect
EU	EU ETS covers N2O from adipic acid and nitric acid production	Forces abatement; adds carbon cost
EU	End-of-life Vehicles Regulation proposal with recycled plastic content targets (2023 proposal)	Would require recycled polymer in new cars, including nylon
US	EPA GHG Reporting Program subpart E (adipic acid)	N2O emissions reported plant by plant
China	N2O abatement under national climate plans (indicative)	Uneven abatement at Chinese adipic acid plants

India

Rule	Effect
DGTR anti-dumping investigation on caprolactam (October 2026)	Could raise PA6 raw material costs
Textile PLI scheme for man-made fibres (2021)	Supports nylon and polyester textile capacity
MSIHC Rules 1989	Covers caprolactam and ammonia handling

Trade measures

DGTR caprolactam anti-dumping investigation (Oct 2026)
No polyamide-specific Indian duty found in sources reached

Supply risk

PA66 supply risk fell sharply as Chinese ADN came on stream. Remaining risks are China's dominance of PA6 chips and the concentration of ADN in a few plants. Not on critical raw material lists.
