Instead of the original March 2025 deadline, vinyl chloride reports are now due by June 11, 2025, and the rest by September 9, 2025. This extension helps manufacturers and importers meet the rules without rushing, keeping everyone safe and informed.

Analyzed Economic Effects

3 provisions identified: 2 benefits, 1 costs, 0 mixed.

Reporting Rule Requires Unpublished Studies

The TSCA Health and Safety Data Reporting rule requires manufacturers (including importers) of 16 specified chemical substances to submit lists and copies of certain unpublished health and safety studies to the EPA. This requirement applies to those manufacturers and importers for the listed chemical substances.

Vinyl Chloride Deadline Extended

If you manufacture or import vinyl chloride, the reporting deadline for submitting lists and copies of certain unpublished health and safety studies to EPA was changed from March 13, 2025 to June 11, 2025. This gives manufacturers and importers more time to prepare their submissions under the TSCA Health and Safety Data Reporting rule.

Other 15 Chemicals Deadline Extended

If you manufacture or import any of the other 15 specified chemicals covered by the rule, the reporting deadline to submit lists and copies of certain unpublished health and safety studies to EPA was changed from March 13, 2025 to September 9, 2025. The extension is intended to help manufacturers and importers meet the rule without rushing.
