Steps
Go to EPA's 'Recognized Third-Party Certifiers' page (epa.gov/formaldehyde/recognized-third-party-certifiers-under-formaldehyde-emission-standards-composite-wood)
Download the current 'Recognized Third-Party Certifiers (TPCs) under TSCA Title VI' PDF list
Cross-check the TPC name against the separate 'Suspended or Revoked Third-Party Certifiers' PDF before relying on their certification
Note the page's last-updated date, since the list is only updated periodically, not in real time
For California-bound products, also check CARB's Certified Mills List, since CARB and TSCA Title VI maintain separate (though harmonized) certifier recognition
Known gotchas
There is no queryable API or live database for TPC status — EPA publishes static PDF lists that must be manually cross-referenced
EPA proposed rule updates in February 2026 to further align TSCA Title VI with CARB's ATCM — re-check for rule changes before assuming current chamber/testing requirements are unchanged
