The California Department of Toxic Substances Control (DTSC) has decided not to classify styrene as a chemical of concern in children’s products, including toys — a significant outcome for the toy industry following extensive technical input from The Toy Association™ and other stakeholders.
The decision, published recently in DTSC’s decision document, concludes that the available scientific evidence does not support regulating styrene in children’s products. Styrene is widely used across many consumer goods, including certain toy materials, and the agency’s determination means no additional regulatory action will be taken on the substance at this time.
“This is a major advocacy win for the toy industry and a strong example of how meaningful engagement in the regulatory process can lead to science-based outcomes,” said Kathrin Belliveau, chief policy officer at The Toy Association™. “Our members provided extensive technical expertise demonstrating that styrene is used safely in children’s products, and we appreciate DTSC’s careful review of the evidence. This decision reinforces the importance of ensuring regulatory actions are grounded in sound science and practical product use.”
The outcome follows a multi-year evaluation process initiated by DTSC. In October 2024, the agency released a “Background Document on Phthalates, Styrene, and Formaldehyde in Children’s Products,” which summarized research on the three substances and sought public comment to determine whether additional regulations — including potential bans — might be warranted in California.
In response, The Toy Association solicited input from member companies, its technical committees, and other expert resources to inform the industry comments. The Association submitted its response to DTSC in January 2025, alongside feedback from more than a dozen companies and industry organizations. Later in October 2025, DTSC requested additional technical information from The Toy Association specifically related to styrene. The Association provided detailed scientific data on the use of styrene in various product categories, demonstrating that regulating the substance as a chemical of concern was not warranted. DTSC’s conclusion reflects the scientific evidence provided by the industry and other stakeholders throughout the review process.
DTSC is now evaluating phthalates and formaldehyde individually. Decisions regarding these two substances have not yet been issued, but the agency is expected to move forward with considerations related to phthalates later this summer.
The Toy Association will continue to keep the industry apprised of developments regarding state regulations.
