Expands recycled content marketing claim requirements from plastic food containers only to all products sold in California

Requires manufacturers to base recycled content claims on actual physical recycled content in products, prohibiting credit-based mass balance accounting, "book-and-claim" accounting, and similar approaches

Defines "postconsumer" as material that would otherwise be destined for disposal after completing its intended end use, excluding manufacturing byproducts commonly reused within the original fabrication process

Locks compliance standards to the Federal Trade Commission Guides for Environmental Marketing Claims as they read on January 1, 2026

Maintains existing requirement that manufacturers provide recycled content documentation to the public upon request, with civil penalties for violations
