TSCA: Overview and Regulatory Framework

What is the purpose of TSCA?

The Toxic Substances Control Act (TSCA), enacted in 1976, empowers the US Environmental Protection Agency (EPA) to require reporting, recordkeeping, and testing of chemical substances. Its primary goal is to ensure that chemicals in commerce do not present an unreasonable risk to human health or the environment. TSCA applies to all chemical substances, including those used in industrial, commercial, and consumer products, and mandates pre-manufacture notification (PMN) for new chemicals before they enter the market.

How does TSCA impact chemical procurement and compliance?

For B2B procurement professionals, TSCA compliance is essential when sourcing chemicals from the US or importing them into the US. Manufacturers and importers must ensure that substances are listed on the TSCA Inventory or have undergone the required pre-manufacture notification process. Non-compliance can result in enforcement actions, product recalls, or market access restrictions. The 2016 amendments to TSCA strengthened the EPA’s authority to evaluate and restrict existing chemicals, increasing scrutiny on substances like PFAS and certain phthalates.

What are the key components of TSCA compliance?

Key elements include the TSCA Inventory (a list of chemicals currently in commerce), the PMN process for new chemicals, and the ability of the EPA to impose restrictions, testing requirements, or bans on chemicals deemed hazardous. Companies must maintain accurate records and may be required to submit data on chemical safety, especially under the Significant New Use Rule (SNUR) framework.

TSCA works alongside other US regulatory frameworks such as REACH (EU), GHS (global hazard communication), and the Clean Air Act. Compliance with TSCA often requires coordination with SDS, CoA, and regulatory documentation to ensure full transparency and traceability in chemical supply chains.
