New Chemicals Analysis

Section 5 of the 2016 TSCA amendments require EPA to determine if a new chemical substance poses an unreasonable risk before the chemical can be manufactured in or imported to the United States.  The statute requires EPA to make this determination within 90 days and allows EPA to extend the review period up to an additional 90 days. 

Of the 379 new chemicals under TSCA review, only 22 have been under review for less than 90 days.

The remaining 357 new chemicals have been under TSCA review for more than 90 days, creating a backlog of advanced chemistries ensnared in the EPA’s review pipeline. 

The number of chemicals under review for greater than 90 days accounts for 94% of the chemicals currently under review with 254 of those PMNs, approximately 67% of the total PMNs,  under review for greater than 1 year.

EPA’s inability to meet the statutorily mandated 90-day deadline to conduct new chemical reviews coupled with the drop in the number of completed chemical reviews has created a significant backlog in the New Chemicals Program, threatening American innovation and manufacturing. 

In a 2022 survey of ACC member companies, 70 percent of respondents reported that they have decided to introduce new chemicals outside of the U.S. due to uncertainties and challenges with the EPA’s New Chemicals Program.

Understanding ACC’s Tracking of EPA’s Progress in TSCA New Chemical Reviews

ACC developed these visualizations to help interpret and track EPA’s performance of the TSCA New Chemicals Program. The data and information were compiled from the following EPA sources: 1) the New Chemicals case tracker and, 2) the Premanufacture Notices (PMNs) and Significant New Use Notices Table
