▍BSMI Introduction Introduction of BSMI certification
BSMI is short for Bureau of Standards, Metrology and Inspection, established in 1930 and called National Metrology Bureau at that time. It is the supreme inspection organization in Republic of China in charge of the work on national standards, metrology and product inspection etc. The inspection standards of electrical appliances in Taiwan are enacted by BSMI. Products are authorized to use BSMI marking on the conditions that they are in compliance with safety requirements, EMC testing and other related tests.
Electrical appliances and electronic products are tested according to the following three schemes: type-approved (T), registration of product certification(R) and declaration of conformity (D).
▍What is the standard of BSMI?
On 20 November 2013, it is announced by BSMI that from 1st, May 2014, 3C secondary lithium cell/battery, secondary lithium power bank and 3C battery charger are not permitted to access to Taiwan market until they are inspected and qualified according to the relevant standards (as shown in table below).

On December 29, 2022, GB 31241-2022 “Lithium ion cells and batteries used in portable electronic equipment —— Safety technical specifications” was released, which will replace the version GB 31241-2014. The standard is scheduled for mandatory implementation on January 1, 2024.GB 31241 is the first Chinese mandatory standards for lithium-ion batteries. It has attracted a lot of attention from the industry since its release and has a wide range of applications. Lithium-ion batteries that apply to standard GB 31241 have been using CQC voluntary certification, but in 2022 it has been confirmed that they will be converted to CCC mandatory certification. So the release of new version of GB 31241-2022 foreshadows the upcoming release of CCC certification rules. Based on this, the following are two recommendations on the current battery certification for portable electronic products:For the time being, it is not recommended to update the CQC certificate to the latest version. As the implementation rules and requirements for CCC certification will be released soon, if you go to update the CQC certificate, you will still need to do a new update when the CCC certification rules are released.In addition, for the already existing certificate, before the issue of CCC certification rules, it is recommended to continue to update and maintain the validity of the certificate, and cancel them after obtaining the 3C certificate.It is ok to continue to apply for CQC certification, and if there is a new test standard, you can choose the new standard for testing
