If you manufacture or sell products in the U.S., recent Environmental Protection Agency (EPA) announcements under the Toxic Substances Control Act (TSCA) may impact you. In December 2024, the EPA finalized new rules that further restrict or phase out the use of several chemicals, including three widely used solvents: trichloroethylene (TCE), perchloroethylene (PCE), and carbon tetrachloride (CTC).

These changes follow earlier TSCA restrictions on persistent, bioaccumulative, and toxic (PBT) substances like phenol, isopropylated phosphate (PIP 3:1), decabromodiphenyl ether (DecaBDE), 2,4,6-tris(tert-butyl)phenol (2,4,6 TTBP), hexachlorobutadiene (HCBD), and pentachlorothiophenol (PCTP).

What’s Changing With TCE, PCE & CTC?

The EPA’s actions are part of a continuous process of reviewing chemicals and setting rules to protect public health and the environment. Here’s what the new rules mean:

TCE

TCE is a volatile organic compound historically found in industrial cleaners, adhesives, and automotive maintenance products. Under the final rule, TCE will be banned from most uses within one year. Certain critical industrial applications have a bit more time but will need to implement strict workplace protections to continue operating legally.

PCE

PCE has been widely used in dry cleaning, paint removers, and manufacturing processes. The new rule phases out most uses of PCE within three years. Dry cleaners will have up to 10 years to switch to safer alternatives, giving the industry time to adopt new, PCE-free technologies. For any ongoing allowed uses, companies must set up strong safety measures in their workplaces.

CTC

CTC has a long history of regulation and was banned in consumer products decades ago. However, it still appears in some industrial processes. The new rule solidifies the end of discontinued uses and requires robust workplace protections for any uses that continue. Companies will have three years to put these safeguards in place.

PBT Substances Remain on the Radar

In addition to these new rules, the EPA is revisiting and updating regulations on PBT substances such as PIP 3:1, DecaBDE, 2,4,6 TTBP, HCBD, and PCTP. While those existing rules stay in effect for now, more changes could be on the way. This is part of an ongoing effort to ensure safer materials and greater transparency in the supply chain.

What Does This Mean for Your Company?

If you operate in the U.S. or sell products there, it’s more important than ever to stay informed. These restrictions might affect the materials you use, the products you sell, and your overall processes. Here’s what you can do:

  • Review your products and supply chains for restricted substances now. Don’t wait until a substance is banned or heavily regulated — start exploring safer alternatives today.
  • The EPA requires you to document the presence of restricted chemicals and maintain those records for at least three years. Having solid documentation on hand helps you respond quickly to new rules and avoid compliance issues.
  • If you identify restricted substances in your products or materials, let your supply chain partners and customers know right away. Clear, timely communication can prevent surprises and costly disruptions.

Preparing for the Future

TSCA restrictions aren’t going away — they’re expanding. More chemicals are being evaluated, and more rules will likely follow. It’s a good idea to stay informed, engage with regulatory developments, and be prepared to pivot as needed.
