New EPA Rules for Chemical Use: What Manufacturers Need to Know

You might care about this because the Environmental Protection Agency (EPA) is putting in place new rules for certain chemicals. These rules are called Significant New Use Rules, or SNURs. They are for chemical substances that the EPA has already looked at and issued orders for under a law called the Toxic Substances Control Act, or TSCA. Basically, if someone wants to start using these chemicals in a new and important way, they have to tell the EPA first. This notification gives the EPA 90 days to check if the new use is safe. Manufacturers and processors cannot just start using these chemicals in new ways without the EPA's approval. The goal is to make sure any new chemical use is carefully reviewed to prevent potential harm. This final rule becomes effective on July 21, 2026. The EPA will review the required notification and make a decision before the activity can begin. This process helps ensure that new uses of these substances meet safety standards. What makes this rule particularly interesting is how it adds another layer of protection. These aren't just new chemicals. These are chemicals that have already been reviewed and are subject to existing EPA orders. The SNURs ensure that any new activities with these already regulated chemicals still go through a strict evaluation process. It means the EPA can step in and require more information or even stop a new use if there are concerns. This prevents companies from finding ways around existing rules by slightly changing how a chemical is used, thinking it's outside the scope of current regulations. It reinforces the idea that public and environmental safety comes first, even for substances already in use. The rule also covers what happens if someone starts a new use after the proposed rule but before the final rule is effective. In such cases, they would have to stop the activity until all EPA requirements are met. If you work in chemical manufacturing or petroleum refining, or if you import or export chemicals, this document directly affects you. Specifically, companies classified under NAICS codes 325 and 324110 should pay close attention. Any business that manufactures, processes, or plans to use these specific chemical substances in a new way will need to follow these rules. Importers also need to be aware because they must certify that their shipments comply with all TSCA rules. Exporters also have reporting duties for certain chemicals. The cost for submitting a Significant New Use Notice (SNUN) is estimated at $45,000 for large businesses and $14,500 for small businesses. There are also costs for export notifications. Basically, if your business handles these regulated chemicals, understanding these SNURs is important to avoid issues and ensure you are following the law.
