Based on the second meeting on inspection regulations for portable power supplies and other commodities convened by the Bureau of Standards, Metrology and Inspection (BSMI) of the Ministry of Economic Affairs, Taiwan on May 5, 2026, the new inspection method for portable power supplies is expected to be officially announced in July or August 2026. After the announcement, industry players may submit applications in accordance with the new method.

For certificate renewal: Holders of old certificates must complete testing in accordance with the new method within one year from the announcement date and submit a renewal application to BSMI actively, with the deadline being July 1, 2027. Certificates that have not been renewed by July 1, 2027 will be directly revoked by BSMI. Relevant parties are requested to pay close attention to the validity period of their certificates.
With the upcoming implementation of the new standard, several inspection requirements have been adjusted. First, the nail penetration test shall only apply to portable power products with a capacity of 160 Wh or below. Currently, battery packs and single cells are not required to undergo the penetration test during certification. In addition, products such as Bluetooth earbud cases, hearing aids, smart watches, smart glasses, and wireless microphones are exempt from the penetration test.
Second, the “R” character track on portable power supplies must be supplemented with the RoHS marking, as shown in the attached figure. (Note: The image shows graphical representations of compliance logos accompanied by the text “R30001 RoHS” and “R30001 RoHS(XX,XX)”, with the Chinese character “或” meaning “or” between the sets).
Regarding factory qualifications, portable power supply factories must provide an ISO certificate. There are three optional inspection methods for application: Provide an ISO certificate issued by a TAF-accredited body. Undergo a factory inspection Conduct batch-by-batch inspection. Information regarding TAF-accredited bodies is for reference only and will be confirmed after the official publication of the new standard. It should also be noted that the new standard may later require CNS 62133 batteries to also provide an ISO certificate issued by a TAF-accredited body; this item is yet to be formally confirmed and shall be subject to the official announcement. We will continue to monitor and follow up on the follow-up developments of this new standard.
