# Hydrochloric acid: Regulation

Corrosive fumes and the danger of mixing with bleach

Source page: https://www.materialinsights.org/chemicals/hydrochloric_acid/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 |
|---|---|---|
| Skin Corr. 1B; Eye Dam. 1; STOT SE 3 (respiratory irritation); Met. Corr. 1 | UN1789 | Corrosive fumes; reacts with metals to give hydrogen; mixing with hypochlorite releases chlorine gas. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | REACH; CLP; Drug precursor regulation (Category 3) | HCl is a scheduled precursor; export licences for some destinations |
| **US** | DEA List II chemical; EPA risk management for anhydrous HCl | record keeping |
| **UN** | 1988 Convention Table II | monitored as a drug precursor |

#### India

| Rule | Effect |
|---|---|
| **BIS standard IS 265 for hydrochloric acid (indicative)** | sets grades and purity for domestic supply |
| **MSIHC Rules 1989** | storage and handling |

#### Trade measures

- None significant

#### Supply risk

Low; supply is local and abundant wherever chlorine is made. Shortages occur only during regional chlor-alkali outages.
