CPA Grademark Certification Program

CPA offers several certification programs (i.e. formaldehyde emissions [HCHO]; physical and mechanical properties [PMP]; engineered wood siding and trim [EWST]; an Eco-Certified Composites [ECC]) for panel producers.  The CPA Grademark Certification Program place a premium on in-plant quality control programs validating personnel, laboratory techniques, and recordkeeping.  Each program has a quality control manual that contains the procedures to meet the requirements of the regulation (e.g. CARB ATCM 93120) or standards (e.g. ANSI A208.1 Particleboard, A135.6 Engineered Wood Siding, A135.7 Engineered Wood Trim and CPA 4-11 ECC Sustainability Standard).  MORE INFO


CPA has full service auditors, located in strategic areas of North America, who can service your plants in support of certification programs or to collect samples for independent testing or CARB reapplications.
