,On April 15, 2026, the World Trade Organization (WTO) circulated notification G/TBT/N/USA/2271 submitted by the United States, announcing the availability of draft risk evaluations for 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[g]-2-benzopyran (HHCB) and phthalic anhydride under the Toxic Substances Control Act (TSCA). The measure is issued by the U.S. Environmental Protection Agency (EPA). The draft evaluations assess whether these chemical substances pose an unreasonable risk to human health or the environment under their conditions of use, including potential impacts on susceptible populations. The evaluations are conducted based on the best available scientific evidence and focus solely on risk considerations, without accounting for economic or other non-risk factors. The EPA is inviting public comments on the draft risk evaluations as part of the regulatory review process. The outcome of these evaluations will inform future regulatory actions, including potential risk management measures if unreasonable risks are identified. The notification is currently open for public consultation, with comments accepted until June 15, 2026. The proposed dates of adoption and entry into force are yet to be determined.
