# Ammonia: Regulation

Toxic clouds, chokepoints and sanctions risk

Source page: https://www.materialinsights.org/chemicals/ammonia/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 |
|---|---|---|
| Flammable gas cat 2; gas under pressure; acute toxicity (inhalation) cat 3; skin corrosion cat 1B; aquatic acute 1 | UN1005 | Large releases form toxic clouds; ammonia storage near cities is a major-hazard risk. Fuel use raises N2O and NOx concerns. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | Seveso III (50 t lower tier, 200 t upper tier); REACH; CBAM covers ammonia (CN 2814) from 2026 | site safety; carbon cost on imports from 2026 |
| **EU** | Tariffs on Russian and Belarusian nitrogen fertilisers rising from 2025 to 2028 (indicative) | shifts EU imports away from Russia |
| **US** | EPA Risk Management Program; 45V and 45Q credits for low-carbon ammonia | safety and decarbonisation incentives |
| **IMO** | Interim guidelines for ammonia as ship fuel (2024, indicative) | enables ammonia-fuelled vessels |

#### India

| Rule | Effect |
|---|---|
| **MSIHC Rules 1989 (ammonia is a listed hazardous chemical)** | on-site and off-site emergency plans |
| **National Green Hydrogen Mission SIGHT Mode 2A green ammonia auctions (2025)** | 724 kt a year contracted, incentive Rs 8.82/kg in year 1 falling to Rs 5.30/kg in year 3 |
| **Nutrient Based Subsidy for DAP/NPK** | passes imported ammonia cost into subsidised fertiliser prices |

#### Trade measures

- EU CBAM from 1 Jan 2026 on ammonia
- EU tariffs on Russian nitrogen fertilisers (2025, indicative)
- US tariff free (USGS)

#### Supply risk

Feedstock and chokepoint risk: gas price shocks and Hormuz. Russia is a large exporter subject to sanctions risk. Nitrogen is not on EU, US or India critical minerals lists, but fertiliser supply is treated as strategic in India.
