The Chemical Data Reporting (CDR) rule, under section 8(a) of the Toxic Substances Control Act (TSCA), imposes reporting requirements on manufacturers and importers of chemicals listed on the TSCA Inventory. Every 4 years, information regarding the manufacturing, processing, and use of such substances must be reported.
Under the CDR Rule, manufacturers (importers) are specifically obligated to report if:
- They have a chemical on the TSCA Inventory as of June 1, 2024
- The chemical(s) are above any applicable regulatory threshold, and
- There is no specific exemption from the requirement to report
For the 2024 submission period, manufacturers and importers are subject to the reporting requirements based on activities conducted during the calendar years 2020 through 2023.
EPA expects that updated guidance documents on submitting information to the CDR database will be available in the fall of 2023.
