Taiwan: Planned BSMI certification for Stationary Lithium Battery Storage Appliances

 

Taiwan has announced its intention to make Stationary Lithium Battery Storage Appliances subject to its national product conformity certification BSMI.

To achieve net-zero carbon emissions by 2050, it is expected that renewable energy power generation equipment and energy storage systems will gradually enter households. Due to the risks associated with thermal runaway in lithium-ion batteries used in energy storage systems, the BSMI proposes to add stationary lithium battery storage appliances into the mandatory inspection scope. Two alternative conformity assessment procedures are made available for the choice of applicants, i.e. Registration of Product Certification (RPC) or Type-Approved Batch Inspection (TABI).

The inspection scope is inspection scope: battery capacity not exceeding 20kWh, with bidirectional power transfer function between the device and the utility grid or other equipment, or equipped with solar photovoltaic module input capability.

Related requirements are:

1. The inspection for the above listed commodity, no matter imported and domestically produced, will begin from 1 July 2025. The import regulation code is C02. From the announcement date, the BSMI can accept applications for Type Approval Batch Inspection and Registration of Product Certification for the above listed commodity.
2. Those who apply for a certificate to the BSMI from the date of announcement shall provide the type test report that meets the inspection standards. The certificate shall be issued after the examination by the BSMI. The validity period of the certificate shall be three years from the date of issuance. (If the issuance date is before 30 June 2025, the effective date will begin from 1 July 2025 and the expire date will be 30 June 2028).
3. The technical documents required for type testing shall comply with the requirements specified in the “Directions Governing Type Approval of Electrical and Electronic Commodities.”
4. Fees for product type-testing: Charged in accordance with the fee regulations of the BSMI’s designated testing laboratory.
5. Fees for product registration of product certification and type approval batch-by-batch inspection: Charged in accordance with the relevant provisions of the “Regulations Governing Fees for Commodity Inspection.”
6. The inspection standards of the products listed in the table shall be the version published in this announcement. If any updated version is available, the BSMI shall publish the implementation date of the updated version in further announcement.
7. The above listed products should indicate the presence of restricted substances in accordance with Section 5 “Labeling” of CNS 15663 (2013) (the example format shown in Table 1 and Table 2) on the body, packaging, label, or instructions. However, for those who provide (disclose) the presence of restricted substances via webpage, the URL link should be clearly stated on the body, packaging, label, or instructions. The location of the indication is not subject to the provisions of Section 5.3 of CNS 15663.
8. After the above listed products are approved by the BSMI for the issuance of certificate, the labeling requirements are as follows:

(1) Based on “Regulations Governing the Use of Commodity Inspection Mark”, the Commodity Inspection Mark shall be printed by the certificate holders. The identification number of the Commodity Inspection Mark consists of “A Letter (R or T),” “Designated Code (5 digits)” and “the presence conditions of the restricted substance” (e.g., RoHS or RoHS (XX,XX)).

(2) The identification number shall be placed below or right next to the graphic symbol and “the presence conditions of the restricted substance” shall be indicated in the second row.

(3) The product inspection mark is not designated with a fixed size, but it should be marked prominently on the product body in an appropriate proportional size. It should be made of durable materials, with clear and legible content that is not easily worn out, and it should be affixed permanently. For those who obtained the Registration of Product Certification before 30 June 2025, they may print the product inspection mark themselves in accordance with the above regulations from the date of obtaining the certificate.
