Our Commitment to Quality

Since 2005, Tet Design has proudly maintained ISO 9001:2008 certification, originally granted by Moody International (now Intertek). As part of our ongoing commitment to excellence, we are currently upgrading our systems to meet the latest ISO 9001:2015 standards. This reflects our dedication to continually improving our quality management system to exceed customer expectations and deliver consistent satisfaction.

Our manufacturing facility is located in a spacious, green area in Nakhon Pathom; just about an hour’s drive from the Bangkok Metropolitan Area.

We warmly invite you to visit us and explore our exclusive designs and latest collections. We would be delighted to arrange a meeting and personally welcome you.
