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 July 25, 2022, Bureau of Standards, Metrology and Inspection (BSMI) issued a draft on the implementation of voluntary product verification of lithium battery used in electric vehicles. On August 16, BSMI officially announced its plan to implement a voluntary verification mode on electrics vehicles with less than 100 kWh, which is composed of Product Test and Conformity Type Statement. Test standard is CNS 16160 (version of year 110), referring to ECE R100.02.
On October 5, 2017, BSMI issued To Implement Regulations for the Inspection of chargers and other four commodities used in electric bicycles, which came into effect on the same day; and become mandatory on January 1, 2019. The Regulations specify the certification requirements for secondary lithium cell/battery used in electric bicycles and secondary lithium cell/battery used in electric assisted bicycles.
Taiwan BSMI Group III stated in a document sent to the general BSMI testing laboratories on July 21, 2022, that a laboratory system management system will be implemented to strengthen the management of designated laboratories and to keep track of the testing progress and situation. The relevant implementation is as follows.
