Over 130 Confidential Chemicals Added to TSCA Non-Confidential Inventory

On May 29, 2024, the U.S. Environmental Protection Agency (EPA) released the latest version of the Toxic Substances Control Act (TSCA) Inventory, which includes 886,770 chemical substances, of which 42,377 are active chemicals. This update to the TSCA Inventory includes the addition of more than 130 substances formerly on the confidential list and 29 existing substances.

For businesses exporting chemicals to the United States, it is crucial to first verify whether the chemicals are listed on the TSCA Inventory. This determines whether they are considered existing substances under the Act, which in turn defines their regulatory obligations. CIRS has updated its database with the latest TSCA Inventory data. Companies in need of this information can conduct a free search at the following website: https://www.chemradar.com/

The TSCA Inventory is updated twice a year to ensure accurate and current chemical data. The next update is expected in early 2025. ChemRadar will continue to provide the latest TSCA Inventory updates.

Confidential Inventory vs. Non-Confidential Inventory

A chemical on the TSCA Non-Confidential Inventory can be identified as an existing U.S. chemical by name or CAS number. For chemicals on the Confidential Inventory, a confidential search is required. U.S. companies must submit a bona fide intent to the EPA for an official inquiry.

Active Substances & Inactive Substances

Under the TSCA Comprehensive Update Act, substances used commercially within ten years are labeled as active, prioritized for screening, and first in line for risk assessments if deemed high-priority. Companies must submit Form B to the EPA to activate inactive substances for production, import, or use. Both active and inactive substances are classified as existing substances in the U.S., requiring enterprises to fulfill two specific obligations.

a. Chemical Data Reporting (CDR)
Entities must submit electronic reports via e-CDRweb for sites with annual chemical production or importation exceeding 25,000 pounds (11.3 metric tons). Reports are required every four years.

b. Significant New Use Reporting (SNUR)
Entities planning to produce or use chemicals designated by the EPA for significant new uses must notify the EPA 90 days in advance. This allows the EPA to review and manage potential risks to human health and the environment.
