Ammonium sulphate: Regulation

Low hazard, high dependence on Chinese export policy

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.
