# Activated carbon: Regulation

Self-heating piles and airless vessels: the hidden hazards

Source page: https://www.materialinsights.org/chemicals/activated_carbon/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; dust may form explosive mixtures; self-heating in bulk | UN1362 (when classified) | Self-heating in large piles, dust explosion and oxygen depletion in wet carbon vessels. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **US** | EPA PFAS National Primary Drinking Water Regulation (April 2024; PFOA and PFOS limits 4 ppt) | Large demand for GAC beds and reactivation |
| **US** | Anti-dumping order on certain activated carbon from China (since 2007) | Shifts US imports to coconut and domestic coal carbon |
| **EU** | Recast Drinking Water Directive (EU) 2020/2184 PFAS limits from 2026 | Raises demand for carbon and other PFAS treatment |
| **International** | Minamata Convention on mercury | Supports carbon injection at combustion plants |

#### India

| Rule | Effect |
|---|---|
| **BIS IS 2752 specification for activated carbon (indicative)** | Grades for water treatment |
| **Coconut Development Board export promotion** | Supports coconut by-product exports |
| **State pollution board consents for kilns** | Air emission limits on charcoal pits and kilns |

#### Trade measures

- US anti-dumping duties on Chinese activated carbon (since 2007)
- No Indian duty found

#### Supply risk

Low overall, but coconut carbon depends on a few producing countries and on shell charcoal supply, which tightened in 2025. Not on critical lists.
