There are news about TSCA deadline for manufacturers and processors . They must notify to EPA (US Environmental Protection Agency) by 5th August 2019 to redefine Inactive substances to Active in the TSCA (Toxic Substances Control Act) inventory. After this date, it's compulsory to submit the Activity Alert Form (NOA-B) within 90 days from the use of an inactive substance.
From its reforming on 22nd June 2016, TSCA relies heavily on the inventory to define new or existing substances in US commerce. After that date, more than 85,000 substances have been updated by EPA. In “The Inventory Reset Rule” published on 11th of August 2017, it's reported that companies notify the EPA during 2018 about substances designated as active, and any substance not notified would be considered inactive. The revised inventory has only about one-half of the substances designated as active so it is very important to check your substances.
