# Nylon (PA6, PA66): Regulation

Nitrous oxide, cyanide and EU carbon pricing

Source page: https://www.materialinsights.org/chemicals/nylon/regulation/

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.
