LISUN actively participates in the relevant work of GB (GuoBiao), and all series of products meet the relevant requirements of GB, and vow to contribute to the quality control of the products made in China!

Guobiao standards or GB standards are the Chinese national standards issued by the Standardization Administration of China (SAC), the Chinese National Committee of the ISO and IEC. GB stands for Guobiao (simplified Chinese: 国标; traditional Chinese: 國標; pinyin: Guóbiāo), Chinese for national standard.

Mandatory standards are prefixed “GB”. Recommended standards are prefixed “GB/T” (T from Chinese language 推荐; tuījiàn; ‘recommended’). A standard number follows “GB” or “GB/T”. GB standards are the basis for the product testing which products must undergo during the China Compulsory Certificate (CCC) certification. If there is no corresponding GB Standard, CCC is not required.
