▍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).

Chinese authority issued an exposure draft of amended version of 25 Requirements on Preventing Electrical Production Accident. The Chinese National Energy Administration made this amendment by arranging discussion with electrical organizations and experts to conclude the experience and accidents happened since 2014, in order to conduct more effective supervise and prevent hazards from happening.
In the exposure draft 2.12 mentions several requirements on lithium-ion batteries in order to prevent fire happening at electrochemistry energy storage station:
Mid-large electrochemistry energy storage shall not use ternary lithium-ion batteries or sodium-sulfer batteries. Echelon traction batteries are not applicable, and should be taken safety analysis based on traceable data.
Lithium-ion batteries equipment room shall not be established in assembly occupancies nor should be set in buildings with residents or basement area. Equipment rooms shall be established in one layer, and shall be pre-fabricated. For one fire compartment the capacity of batteries shall be no more than 6MW`H. For equipment rooms with capacity larger than 6MW`H, there should be automatic fire extinguish system. The specification of the system shall follow 2.12.6 of the exposure draft.
