Certification Requirements

The Porcelain Tile Certification Agency (PTCA) has established a certification program for manufacturers and sellers of porcelain tile. The program is based upon strict compliance with the requirements of conforming porcelain tile defined as ceramic tile that has a water absorption of 0.5% or less, when tested in accordance with ASTM C373.

PTCA owns the exclusive rights to the PTCA Certification Mark, referred to as the Mark, which it has granted others limited rights to use in connection with promotion of its certification program. The Mark is set out in attachment C of the program participation agreement and is shown here:

Frequently Asked Questions

Q: What is PTCA?

A: It is a joint creation of TCNA & CTDA to meet an industry need to certify if tiles meet the water absorption requirements for porcelain. PTCA was created because tiles are being sold in the U.S. that were marked as porcelain, but which were in fact not porcelain.

Q: How does PTCA benefit the industry?

A: This program is designed to directly benefit consumers purchasing porcelain tile and indirectly, everyone involved in the supply chain (i.e. manufacturers, distributors, retailers, etc.). Having certified tile helps end the confusion caused by tiles being misrepresented as porcelain and provides an assurance to the consumer that the tiles they purchase are truly porcelain.

Q: What tests have to be performed for my tile to qualify as porcelain?

A: The ASTM C373 test for water absorption. Five (5) tile samples are tested, and if the average water absorption is 0.5% or less, then that tile qualifies to be certified as porcelain.

Q: How much does it cost to participate?

A: The initial certification and participation fee is $500 for the first qualifying series submitted and $100 for each additional series. These fees do not include testing. Participants shall renew their certification annually for a fee of $100 per series, up to a maximum of $1000 for the duration of the agreement.

Q: Do I have to have my tiles retested at some point to continue being certified?

A: Yes. For participants that manufacture certified tile, re-qualifying tests must be performed every three years. For all other participants re-qualifying tests must be performed annually.

Q: Where can I get the paperwork necessary to submit my tiles for certification?

A: The participation agreement can be found here and should be submitted to PTCA. Click here to obtain the testing order form to submit directly to Tile Council’s testing lab.

Q: Do I have to send all colors in a series to get that series qualified?

A: No, only the lightest color in the series should be submitted for testing.

Q: How many samples do I need to submit for testing?

A: Five (5) samples that are at least 12" x 12". For mosaics, twenty (20) samples of the largest size in the series are needed per test.

Q: I need my results quickly! Does PTCA offer expedited service?

A: Yes, TCNA’s testing lab offers expedited service. For tests initiated within 24 hours, there is a 100% surcharge. For test initiated within 3-5 days, the surcharge is 50%. Contact TCNA’s testing lab at 864-646-8453 for expedited testing.

Q: What happens if my tile qualifies as porcelain?

A: You will receive a confirmation letter from TCNA’s testing lab, and a copy will be sent to PTCA. PTCA will then send you the PTCA logo (after it receives a copy of the participation agreement and payment of fees).
