TSCA Act background

The United States Toxic Substances Control Act (Toxic Substances Control Act), referred to as TSCA. The bill aims to comprehensively consider the environmental, economic and social impact of chemical substances circulating in the United States and prevent "unreasonable risks" to human health and the environment. After several revisions, TSCA has become an important regulation for effective management of chemical substances in the United States.

In January 2021, the U.S. Environmental Protection Agency (EPA) restricts the use of these five persistent, bioaccumulative, and toxic (PBT) chemical substances in accordance with the final rules for five persistent, bioaccumulative, and toxic (PBT) chemical substances published by TSCA in the Federal Register.

TSCA control scope

Chemical substances or chemicals that are circulated in the United States and belong to the TSCA regulatory category.


With the introduction of new EPA regulations, TSCA hazardous substance control will be implemented in phases from March 8, 2021. Relevant companies need to pay attention to the qualification of products in advance, otherwise they will be prohibited from listing.
