Under the 2016 TSCA amendments, EPA has 90 days to review and make a determination on a new chemical before the manufacturer can commence production of the new substance (or import the substance) can enter the marketplace. If needed, TSCA authorizes EPA to extend the review period by an additional 90 days, totaling 180 days.
Of the 431 new chemicals under TSCA review, 52 are active and currently under review within the 90-Day TSCA-mandated review period.
383 new chemicals, representing 88.9% of active PMN cases, have been under EPA review for more than 90 days. The 90-day backlog of PMN cases decreased by 0.5% since December 24, 2024.
250 active PMN cases, or 58%, have been under review for 365 days or more. The 365-day backlog has decreased by 0.8% since December 24, 2024.
As the demand for innovative chemistries grows, the backlog of new chemicals awaiting TSCA review beyond the 90-day period is impeding investments in the production of new and innovative chemicals here in the United States.
70% of ACC member companies surveyed reported choosing to introduce new chemicals outside the U.S. due to uncertainties and challenges with the EPA’s New Chemicals Program.
Since June 22, 2016, there have been 36 PMN reviews completed within the 90-Day TSCA-mandated review period.
