The Ceramic Tile Distributors Association (CTDA) and the Tile Council of North America (TCNA) will launch the Porcelain Tile Certification Agency (PTCA) to certify porcelain tile. The initiative is motivated by installation problems, liability concerns and marketplace confusion.

The program, designed to benefit manufacturers, distributors and end-users impacted by non-porcelain tile misrepresentations, will consist of an application process that involves manufacturers submitting samples of each tile series to be certified, and by paying fees involved with the testing, as well as initial and annual certification fees. Recertifying tile every three years will also be required.
