About PTCA

The Porcelain Tile Certification Agency (PTCA) was established jointly by the Ceramic Tile Distributors Association (CTDA), representing distributors, and the Tile Council of North America (TCNA), representing manufacturers.

Together these two groups of ceramic tile industry leaders represent a total of more than 500 distributors and manufacturers. PTCA is a result of their belief that misunderstandings on the definition of porcelain tile and mislabeled products result in complex and often costly problems. They have agreed that a product certification program for porcelain tile will help mitigate these problems.

Under the program, manufacturers who want to "prove" their product is really porcelain (meeting the water absorption criteria of the American national standard) can have their product tested to determine compliance with that criteria. Use of the porcelain certification mark on their product packaging, marketing materials, and more confirms that compliance.
