# Sodium silicate: Regulation

Low risk, abundant inputs, slippery spills

Source page: https://www.materialinsights.org/chemicals/sodium_silicate/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 and eye irritation (category 2) for neutral grades; skin corrosion for metasilicates and low-ratio grades | UN3253 (metasilicate); solutions usually not regulated | Alkaline burns and eye damage; slippery spills. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | REACH registration; soda ash production in EU ETS | Carbon cost passes through soda ash |
| **US** | Generally recognised as safe uses in some food applications (indicative) | Allows food and water uses |

#### India

| Rule | Effect |
|---|---|
| **BIS IS 381 specification for sodium silicate (indicative)** | Sets commercial grades |
| **State pollution control board consent for furnaces** | Air emission limits for small furnaces |

#### Trade measures

- None found

#### Supply risk

Low: raw materials are abundant and producers are spread across many countries. Local supply depends on soda ash availability.
