American Trademarking Agencies

U.S. engineered wood products are manufactured to conform to North American voluntary national standards, proprietary standards as well as some European Standards.  The trademark that appears on the product is the manufacturer’s assurance that the product conforms to the standard indicated on the trademark.

Several independent agencies provide quality assurance services to U.S. manufacturers of which APA – The Engineered Wood Association and TECO Corporation are two major participants.
