▍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).

▍Why MCM?
● In 2014, rechargeable lithium battery became mandatory in Taiwan, and MCM began to provide the latest information about BSMI certification and the testing service for global clients, especially those from mainland China.
● High Rate of Pass: MCM has already help clients to obtained more than 1,000 BSMI certificates till now in one go.
● Bundled services: MCM helps clients successfully enter multiple markets in worldwide through one-stop bundled service of simple procedure.
Recently International Electrotechnical Commission EE has approved, released and canceled several CTL resolutions on batteries, which mainly involves portable battery certification standard IEC 62133-2, energy storage battery certificate standard IEC 62619 and IEC 63056. The following is the specific content of the resolution:In December 2022, CTL issued a resolution that the voltage of the battery pack products cannot exceed 60Vdc. There is no clear statement about voltage limit in IEC 62133-2, but it refers to the IEC 61960-3 standard.
The reason why this resolution was cancelled by CTL is that “the upper voltage limit of 60Vdc will restrict some industry products from undergoing this standard test, such as power tools, etc.”
Similarly, in the interim resolution issued in December last year, it was proposed that when charging at the method of Article 7.1.2 (requiring charging at the upper and lower charging temperature limits), although in Appendix A.4 of the standard it states that when the upper/lower charging temperature is not 10℃/45℃, the expected upper charging temperature needs to be +5℃ and the lower charging temperature needs to -5℃. However, during the actual test, the +/-5°C operation can be omitted and charging can be carried out according to the normal upper/lower limit charging temperature.
This resolution was passed at this year’s CTL plenary meeting.
