Effective October 1, 2023: Motor Vehicle Tires Containing N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD)

The California Department of Toxic Substances Control (DTSC) has finalized a regulation pursuant to the Safer Consumer Products (SCP) Regulations to list a new Priority Product: motor vehicle tires containing N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD), effective October 1, 2023.

Domestic and foreign manufacturers of motor vehicle tires (as defined in the regulation) that contain 6PPD and whose products are placed into the stream of commerce in California must submit a Priority Product Notification (PPN) for those products by November 30, 2023. After submitting the PPN, manufacturers have the option to submit one of the following through CalSAFER by March 29, 2024:

The responsibility to comply falls first on manufacturers, but if a manufacturer fails to comply, the responsibility to comply may shift to importers or retailers, if DTSC notifies them accordingly.

Manufacturers of motor vehicle tires whose products do not contain 6PPD need not take any action.
