# Ammonium sulphate: Regulation

Low hazard, high dependence on Chinese export policy

Source page: https://www.materialinsights.org/chemicals/ammonium_sulphate/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 |
|---|---|---|
| generally not classified; some suppliers list eye irritation | not regulated | Low hazard; by-product grades can carry heavy metals or organics from source processes. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | Fertilising Products Regulation 2019/1009 contaminant limits; CBAM covers fertilisers from 2026 | Chinese AS faces CBAM costs from 2026, prompting the 2025 rush of imports |
| **EU** | REACH registration | standard |
| **Codex / food** | Food additive E517 | food-grade specifications |

#### India

| Rule | Effect |
|---|---|
| **Fertiliser (Control) Order 1985: AS at least 20.6% N and 23% S (indicative)** | quality specs |
| **Nutrient Based Subsidy covers AS (20.6-0-0-23)** | subsidy per kg N and S caps farm price |

#### Trade measures

- China export inspections on fertilisers since late 2021, eased for some products in March 2026 (Argus)
- EU CBAM from 2026

#### Supply risk

Low for the product (many by-product sources), but trade depends heavily on Chinese export policy.
