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
not classified as a polymer; residual styrene and butadiene (carcinogen category 1A) limited
not regulated
Butadiene handling at plants carries fire, explosion and carcinogen risks; fire in bale storage.
Main rules
Where
Rule
Effect
EU
Tyre Labelling Regulation (EU) 2020/740
Rewards low rolling resistance, favouring SSBR and silica
EU
REACH Annex XVII entry 50 PAH limits in extender oils
Forced switch from aromatic oils to TDAE in oil-extended SBR
EU
Euro 7 (Regulation (EU) 2024/1257) tyre abrasion limits to follow
Will regulate tyre wear particles
US
EPA NESHAP for polymers and resins; butadiene exposure limits (OSHA)
Plant emission controls
India
Rule
Effect
DGTR final findings, 20 March 2026: anti-dumping duties recommended on ESBR from EU, Japan, Korea, Russia and Thailand
Raises import parity by $51-319/t once notified by the finance ministry (notification not confirmed in sources reached)
BIS star labelling for tyres (rolling resistance, wet grip; indicative)
Could raise SSBR demand
Hazardous and Other Wastes Rules: end-of-life tyre EPR (2022)
Tyre makers must ensure recycling of waste tyres
Trade measures
India ESBR anti-dumping duties recommended March 2026
EU sanctions on Russian goods affect Sibur's European sales (indicative)
Supply risk
Moderate. Many producers, but tied to butadiene, a by-product of naphtha cracking. Natural rubber offers partial substitution.
