CAS 9003-07-0 · TSCA · United States of America

Polypropylene (PP) under TSCA

(C3H6)n · 聚丙烯

Status: Listed. Polypropylene is on the TSCA Inventory and is currently listed as TSCA Active. Light-regulatory profile. NOT on EPA RMP threshold list. NOT on DEA scheduling. NOT on Cal Prop 65. NOT on TRI Section 313 list. NO active US AD case on Chinese-origin PP currently. Section 301 List 3 25% additional duty applies on Chinese-origin PP (HS 39021000). FDA 21 CFR 177.1520 indirect food-additive applications for plastic food-contact materials. State-level single-use plastics legislation (California + Maine + New York extended-producer-responsibility laws).

The US PP lane has **light regulatory profile**. Section 301 List 3 25% additional duty applies. Major US producers: ExxonMobil, **LyondellBasell (a leading PP producer; verify the most recent global PP nameplate against the LyondellBasell investor site before quoting world-largest rank or a specific Mt/yr figure)**, Phillips 66 / CP Chem, INEOS Olefins & Polymers, Total Petrochemicals. State-level single-use plastics legislation drives recycled-content + EPR.
