EPA Tweaks Chemical Rules to Ease Some New Uses

## Summary

The EPA is updating rules about certain chemicals to make it easier to use some new ways without extra paperwork, based on fresh data and past reports. Companies making or using these chemicals need to know the new rules start January 11, 2027, so they can stay in the clear and avoid surprises. This update helps keep everyone safe while cutting down on unnecessary red tape.

## Abstract

EPA is amending significant new use rules (SNURs) issued under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for certain chemical substances identified herein, which were the subject of premanufacture notices (PMNs) and significant new use notices (SNUNs). This action amends the SNURs by allowing certain new uses reported in the SNUNs or PMNs without additional notification requirements, modifying the significant new use notification requirements based on the actions and determinations for the SNUN or PMN submissions or based on the examination of new test data or other information, and making technical amendments to several SNURs. EPA is issuing these amendments based on review of new and existing data for the chemical substances.

## Effects PRIA read

- New SNUR effective and promulgation dates: cost, medium. The final rule becomes effective January 11, 2027, and for purposes of judicial review is promulgated at 1 p.m. (EST) on November 24, 2026. If you manufacture, process, or use the listed substances, these are the dates by which the new SNUR requirements take effect.
- SNUN submission costs for firms: cost, high. If you submit a Significant New Use Notice (SNUN), EPA estimates total preparation and submission costs of about $45,000 per SNUN for large business submitters and about $14,500 per SNUN for qualifying small business submitters. These estimates include the user fee and registration costs.
- Reduced SNUN user fee for small businesses: benefit, medium. Qualifying small businesses pay a reduced SNUN user fee of $6,480 instead of $37,000, which EPA says reduces the total SNUN submission cost to about $14,500 for small firms. EPA states this reduced fee is available under the fee rules (40 CFR 700.45(c)(1)(ii) and (d)).
- Export notification one-time cost: cost, low. If you export a substance subject to a SNUR, you must submit a one-time export notification to EPA the first time you export to a particular country; EPA estimates the per-notification cost at approximately $106. The total cost depends on how many countries you export to.
- Cutoff date for ongoing uses: Oct 28, 2025: cost, medium. EPA designates October 28, 2025 (the date of publication of the proposed rule) as the cutoff for determining whether a use is 'ongoing.' If a person began commercial manufacture or processing for a use after that publication date and before the final rule's effective date, they must cease the activ…
- Some reported new uses now allowed without extra notice: benefit, medium. EPA states it is amending SNURs by allowing certain new uses reported in SNUNs or PMNs to proceed without additional notification requirements and by modifying notification requirements based on review of SNUN/PMN submissions and new test data. This change may reduce the number of new SNUNs some fi…
- Specific recordkeeping requirements for listed substances: cost, low. For some amended SNURs EPA imposes specific recordkeeping obligations: e.g., for PMN P-03-622 recordkeeping per Sec. 721.125(a)-(i) and (k) applies, and for the microorganism Trichoderma reesei (Sec. 725.1080) recordkeeping per Sec. 725.950(b)(2)-(4) and documentation of compliance with paragraph (…
