EPA Adds 206th PFAS Compound to Toxics Release Inventory as Reporting Requirements Expand
EPA Adds 206th PFAS Compound to Toxics Release Inventory as Reporting Requirements Expand
What Changed
EPA finalized a rule on February 23 adding sodium perfluorohexanesulfonate (PFHxS-Na) to the Toxics Release Inventory (TRI). Companies using 45 kg or more annually must report starting from January 1, 2026, with first reports due July 1, 2027. This brings the total number of PFAS compounds on the TRI to 206.
The addition was triggered by the Fiscal Year 2020 National Defense Authorization Act, which requires automatic TRI listing once EPA completes a toxicity assessment for a PFAS compound. EPA finalized its toxicological review of PFHxS in January 2025.
Why It Matters
The TRI is the primary public database for tracking chemical releases and waste management at industrial facilities across the United States. Each PFAS addition expands the scope of mandatory corporate reporting and puts more data into the public record.
PFHxS and its salts have been used in metal plating, firefighting foam (AFFF) formulations, and surface treatment processes. If your facility handles PFAS-containing products, this expansion means you should evaluate whether any of your materials contain PFHxS-Na and track quantities against the 45 kg reporting threshold.
"This addition ensures communities have the right to know what chemicals are being used and released in their neighborhoods," said Doug Troutman, EPA assistant administrator for chemical safety and pollution prevention.
Key Details
- Chemical added: Sodium perfluorohexanesulfonate (PFHxS-Na)
- Reporting threshold: 45 kg (approximately 100 lbs) per year
- Reporting period start: January 1, 2026 (retroactive)
- First reports due: July 1, 2027
- Total PFAS on TRI: 206 compounds (9 added in 2025, 7 added in 2024)
- Legal basis: FY2020 National Defense Authorization Act — automatic listing upon completed toxicity assessment
What Chemical Buyers Should Do Next
The pace of PFAS additions to the TRI is accelerating. The NDAA mechanism means that every time EPA completes a toxicity review of a PFAS compound, it automatically gets added to the inventory with no additional rulemaking needed.
For companies that buy or use chemical products in manufacturing, water treatment, or surface finishing, this creates a practical imperative: know what is in your supply chain. Request detailed composition data from suppliers, particularly for any products that may contain fluorinated compounds. The 45 kg threshold is low enough that even moderate-volume users could trigger reporting obligations.
Review your current chemical inventory for any PFAS-containing products. Cross-reference against the full TRI PFAS list to determine whether your facility has new reporting duties. If you are uncertain about product compositions, contact your suppliers for Safety Data Sheets and Certificates of Analysis that detail fluorinated compound content.
Alliance's Take
The expanding PFAS reporting landscape is something Alliance Chemical takes seriously. As a supplier, we prioritize providing complete documentation — including Safety Data Sheets and Certificates of Analysis — so our customers can evaluate their materials against evolving regulatory requirements.
If you work with fluorinated compounds or PFAS-adjacent products, now is the time to audit your inventory against the updated TRI list. Alliance Chemical stocks a range of water treatment chemicals and lab-grade reagents with full documentation available at order.

Frequently Asked Questions
What is the new PFAS compound added to the EPA Toxics Release Inventory?
The EPA recently finalized a rule adding sodium perfluorohexanesulfonate (PFHxS-Na) to the Toxics Release Inventory (TRI). This addition brings the total number of PFAS compounds on the list to 206. The listing was triggered by the National Defense Authorization Act following a completed toxicity assessment finalized in January 2025.
What are the reporting requirements for PFHxS-Na under the TRI?
Facilities that use 45 kg or more of sodium perfluorohexanesulfonate annually must comply with reporting requirements. The reporting period began retroactively on January 1, 2026. Companies must submit their first reports by July 1, 2027, to remain compliant with the expanded EPA safety and environmental regulations for tracking chemical releases.
Why was PFHxS-Na added to the Toxics Release Inventory?
Under the Fiscal Year 2020 National Defense Authorization Act, PFAS compounds are automatically added to the TRI once the EPA completes a toxicity assessment. Following the finalization of the toxicological review for PFHxS in early 2025, the compound was added to the public database to track industrial releases and waste management.
How should chemical buyers prepare for expanded PFAS reporting requirements?
Industrial facilities should audit their current chemical inventories for products containing fluorinated compounds. Buyers should request detailed composition data, Safety Data Sheets, and Certificates of Analysis from suppliers to determine if they meet the 45 kg reporting threshold. This ensures accurate tracking of substances used in metal plating and surface treatments.
