China GB Testing
What is the China GB Testing?
GB is an abbreviation of "GUO JIA BIAO ZHUN," the Chinese pinyin for National Standards
(国家标准). Apparel, decorative, and household textile products manufactured or sold in China must comply with
the requirements of GB 18401 - National Textile Products Basic Safety Technical Code.
*Since 2008, we have been the first domestic testing and certification organization to collaborate with
Chinese national institutions, providing testing and consulting services for exports to China.
