The U.S. Environmental Protection Agency (EPA) is finalizing a rule that will restrict imports of perfluorinated chemicals that could be used in carpets. The regulation will require companies to report to EPA all new uses, including in domestic and imported products, of these chemicals once used for soil and stain resistance in carpets.

The rule known as a Significant New Use Rule under the Toxic Substances Control Act, requires that anyone who intends to manufacture (including import) or process any long-chain perfluoroalkyl carboxylic (LCPFAC) chemicals for use in carpets or carpet products submit a notification to EPA at least 90 days before beginning the activity, providing the agency with an opportunity to review and, if necessary, place limits on manufacturers or processors who intend to reintroduce or import products with these chemicals.
