EPA Extends the Reporting Deadline for 2024 Chemical Data Reporting Period 

The EPA is extending the submission deadline for 2024 Toxic Substances Control Act (TSCA) Chemical Data Reporting (CDR) reports from September 30 to November 22, 2024. The CDR regulations require manufacturers (including importers) of chemicals listed on the TSCA Chemical Substance Inventory (TSCA Inventory) to report data on the manufacturing, processing, and use of those chemicals every four years. For the 2024 data submission period this applies to activities conducted during the calendar years 2020-2023.

The CDR database helps EPA and a variety of interested parties—including communities, other regulatory agencies, industry, researchers and nongovernmental organizations—understand the types, quantities, and uses of chemicals produced domestically or imported into the United States. Understanding how chemicals are being used also helps EPA screen and prioritize chemicals to identify and evaluate potential human health and environmental effects.

EPA is extending the submission deadline in response to recent concerns related to the 2024 reporting tool and technical issues with the ability of the reporting tool to correctly capture substantiations for chemical identity confidential business information (CBI) claims across multiple chemicals. When the copy function in the reporting tool is used, some of the questions and their responses are not copied and are not included with the submission. The reporting tool also prevents a user from adding the missing information if the copy function was used. EPA anticipates that the reporting tool will be working properly by the end of September. This issue only affects submissions with multiple CBI claims. As of now, approximately 29 submissions involve at least one CBI claim for a chemical identity. EPA has not yet confirmed how many of these 29 submissions involve more than one chemical identity being claimed as CBI. This extension only applies to the 2024 submission period.
