Recognized Third-Party Certifiers under the Formaldehyde Emission Standards for Composite Wood Products Rule

This page contains the names of Third-Party Certifiers (TPCs) recognized by EPA to provide certification services under the Formaldehyde Emission Standards for Composite Wood Products Rule. All producers of composite wood panels are required to have their products tested by an EPA-recognized TPC to ensure their products are compliant with the formaldehyde emission standards found in the rule. TPCs are accredited and overseen by EPA-recognized Accreditation Bodies (ABs). This list of EPA-recognized TPCs is updated periodically.

This page also contains the names of TPCs whose EPA recognition has been suspended or revoked. Read about the process of suspending or revoking a TPC’s recognition status under the Formaldehyde Emission Standards for Composite Wood Products Rule.
