New uses for certain chemicals now need US environmental regulator approval

US environmental regulators now require pre-approval for new uses of specific chemical substances. Companies cannot make or import these chemicals for new purposes until the regulators review and approve the plan.

Companies cannot just start using these chemicals in new ways. They must wait 90 days for the US environmental regulators to review their plans. The regulators can then block or change those plans, adding time and cost to bringing new chemical applications to market.
