China Testing & Certification International Group Co., Ltd. (CTC, Stock Code 603060) originated from the testing and certification business of China Building Materials Academy in the 1950s. After 70 years of unremitting efforts and persistent pursuit, the company has formed five business categories: detection and testing, certification and evaluation, testing instruments and intelligent manufacturing, measurement and calibration, scientific research and technical services, committed to providing customers with technical services and comprehensive solutions of detection and testing, certification and evaluation, appraisal, consultation, training, and instruments and equipment in fields of quality, environmental protection, green, safety, health, and energy conservation.

The development of dry-mix mortar in China began in the 1980s and 1990s. In the early 2000s, with the introduction of national policies on energy conservation and emission reduction, external thermal insulation rendering and bonding mortars became the driving force for the development of dry-mix mortar. In recent years, specialized mortars such as tile adhesives have brought another wave of growth to the dry-mix mortar industry. Since 2012, the market has grown at an annual rate of no less than 30%, making China the world’s largest producer and consumer of dry-mix mortar.
We have a professional testing team capable of providing differentiated testing services, helping your products stand out while meeting general market requirements.
