# Polymer additives: Regulation

How lead, PFAS and UV-328 bans shift additive demand

Source page: https://www.materialinsights.org/chemicals/polymer_additives/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 phenolic antioxidants not classified; some organotins: reproductive toxicity and STOT; lead stabilisers: reproductive toxicity cat 1A | varies; organotins UN2788 or UN3146 | Lead and some organotin compounds are toxic; PFAS processing aids persist. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | REACH restriction on lead in PVC, Regulation (EU) 2023/923 | lead stabilisers phased out |
| **Global** | Stockholm Convention listing of UV-328 (2023) | UV absorber substitution |
| **EU** | Proposed universal PFAS restriction | fluoropolymer processing aids under pressure |
| **EU/US** | Food contact rules (EU 10/2011, FDA) | positive lists for additives in packaging |

#### India

| Rule | Effect |
|---|---|
| **BIS standards for PVC pipes moving to lead-free stabilisers (indicative)** | shift to Ca-Zn and organotin |
| **Plastic Waste Management Rules (EPR)** | recycled content raises re-stabilisation demand |

#### Trade measures

- US trade measures affecting Asian suppliers (Songwon, 2025)

#### Supply risk

Low for standard grades; specialty light stabilisers have few suppliers.
