News Details

The United States Environmental Protection Agency (EPA) has issued a final rule establishing 29 Significant New Use Rules (SNURs) under the Toxic Substances Control Act (TSCA). The rule requires manufacturers, importers, and processors to notify the EPA at least 90 days in advance of introducing any new or modified use of specified chemicals. These substances include specialty chemicals and industrial intermediates, many of which are identified by generic names because their identities are claimed as confidential business information. 

The measure will take effect on July 21, 2026, and aims to ensure that any new application of these substances undergoes a thorough risk assessment before entering the market.  

Wider Control over Industrial Activities 

The regulation applies to chemical use in industries such as manufacturing, petroleum refining, and consumer product development. It covers activities such as production, processing, distribution, disposal, and environmental release.  

Certain practices such as spray applications, uncontrolled emissions, or disposal methods outside approved standards are categorized as “significant new uses”, which trigger mandatory EPA review. The rule also enforces requirements for: 

• Workplace safety measures (protective equipment, exposure controls) 

• Hazard communication (labels and warnings) 

• Controls on environmental release, particularly water contamination 

These provisions aim to limit human exposure and environmental impact from chemicals that may pose health risks.  

Compliance Costs and Industry Response 

EPA estimates that each Significant New Use Notice (SNUN) submission could cost approximately $45,000 for large companies and $14,500 for small businesses, including preparation and regulatory fees.  

While these costs may seem high, the agency notes that only a limited number of such notices are typically filed annually. Reduced fees and exemptions are available for small businesses to ease the financial burden. Additionally, export and import activities involving these chemicals must meet certification and notification requirements to ensure compliance with U.S. safety laws.  

Focus on Public Health and Environmental Protection 

The central goal of the SNUR framework is to prevent potential harm before it occurs. By requiring advance notification, the EPA can evaluate risks related to human health, workplace exposure, and environmental release. If necessary, the agency can impose restrictions or prohibit certain uses entirely. 

Implications for Global Trade and Regulation 

The new rule is also significant for international trade because exporters supplying chemicals to the United States must comply with these updated standards. The rule reflects EPA's continued implementation of the TSCA new chemicals program by requiring advance notification before designated significant new uses are initiated. 

Overall, the regulation represents a shift toward stricter oversight, ensuring that innovation in chemical use is balanced with safety and sustainability considerations.
