U.S. Toxic Substances Control Act Chemical Inventory

Since 1977, the TSCA Inventory has grown to include the identities of over 83,000 chemical substances. This dataset lists non-confidential chemical substances manufactured or imported in the United States. The U.S. Environmental Protection Agency maintains this list of non-confidential chemical substances submitted under the Toxic Substances Control Act to manage risks to human health and the environment.

Use Cases

• Cross-reference chemical substance identities from the inventory with other regulatory or hazard databases for compliance screening.
• Analyze the growth of the inventory over time by tracking Notices of Commencement to identify trends in new chemical introductions.
• Filter the inventory to identify substances based on their confidential or non-confidential status for public transparency studies.

Strengths

• Contains over 83,000 chemical substance identities, providing a broad scope of industrial chemicals in U.S. commerce.
• Maintained by the authoritative U.S. Environmental Protection Agency with a documented update process via Notices of Commencement.
• Has a long temporal coverage, with data collection governed by a rule established in 1977.

Limitations

• Contains only non-confidential chemical identities, omitting substances protected as confidential business information.
• The dataset's structure and available features (columns) are not specified in the input, limiting understanding of its analytical depth.
• May not include real-time updates, as substances are added following a formal EPA review and notification process.
