What

Which TSCA items should I focus on?

For electronic products, supply chain components, or raw materials, the primary focus should be on the five PBTs and the ten substances on the First Priority List. PBTs refer to Persistent, Bioaccumulative, and Toxic substances mentioned in TSCA Section 6. The ten First Priority List substances were identified by the EPA in 2016 as requiring urgent risk evaluation; all ten have now completed evaluation and are identified as posing risks.

Who

Who needs to comply with US TSCA?

Chemical substances, articles (finished products), and end-products manufactured in or imported into the United States are subject to TSCA regulations. To ensure product compliance, brand owners also require their suppliers to perform due diligence to ensure the supply chain is free of restricted substances.

Why

Why comply with US TSCA?

TSCA aims to reduce the risks that toxic chemical substances pose to the environment or users. Products that do not meet TSCA requirements not only fail to satisfy buyer specifications but also face heavy fines from regulatory authorities, which can reach up to USD 49,772 per day.

When

When did US TSCA take effect?

The management rules for the five PBTs took effect on February 5, 2021. For the ten First Priority List substances, formal management rules have been announced successively since 2024.
