# Construction chemicals: Regulation

How carbon declarations are entering concrete tenders

Source page: https://www.materialinsights.org/chemicals/construction_chemicals/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 |
|---|---|---|
| most admixtures unclassified or mild irritants; isocyanates respiratory sensitisers; epoxy resins skin sensitisers; cement-based products cause skin and eye damage | varies by product; none for most admixtures | Worker exposure to isocyanates and epoxy in floors and sealants; chromium(VI) in cement-based mortars. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | EN 934-2 admixture standard and CE marking; REACH diisocyanate restriction requiring training (from Aug 2023); EN 15804 EPDs | EPDs and low-carbon concrete criteria are entering public tenders. |
| **US** | ASTM C494 admixture specification; Buy Clean rules requiring EPDs for concrete in some states | Pushes producers to publish carbon data for mixes. |

#### India

| Rule | Effect |
|---|---|
| **BIS IS 9103 concrete admixtures; IS 456 code of practice for concrete** | Sets performance requirements for admixtures used in structural concrete. |
| **BIS quality control orders on some construction products (indicative)** | Raise compliance cost for importers. |

#### Trade measures

- No anti-dumping duty on construction chemicals found in sources reached

#### Supply risk

Low: formulation is local and inputs are widely available. The main exposure is to ethylene oxide and acrylic acid prices, which rose with oil in 2026.
