The U.S. Environmental Protection Agency (EPA) has issued important regulations under TSCA (Toxic Substances Control Act) for Deca-BDE (Decabromodiphenyl Ether) and PIP (3:1) (Phenol, Isopropylate Phosphate 3:1). These changes came into force on January 21, 2025. The amendments aim to reduce the risks associated with these chemicals for both human health and the environment. The amendments were finalized following public feedback and additional data collection.
The regulations specifically target Deca-BDE, a flame retardant used in electronics, textiles and aerospace. Key updates include requiring the use of personal protective equipment (PPE) in certain processing processes, prohibiting the release of Deca-BDE into water during production, and extending the compliance date for critical uses such as cable insulation in nuclear power plants. In addition, products are allowed to contain undesirable amounts of Deca-BDE at concentrations below 0.1%.
Similar regulations have been made for PIP (3:1), making the use of PPE mandatory in manufacturing and processing processes related to the use of this chemical as a plasticizer and flame retardant. For PIP (3:1), EPA has extended compliance dates for certain applications, while allowing commercial distribution of these substances in new and replacement parts. The regulations aim to reduce exposure to these chemicals and ensure safe conditions of use, especially in sectors where alternatives are not available.
These regulations reflect EPA’s ongoing commitment to reduce the environmental and health impacts of hazardous chemicals under the TSCA framework. The changes take an important step forward in protecting workers and the general public, and mean that industries will need to adapt to the new requirements. These regulations will be implemented following a thorough review process and feedback from stakeholders.
