Power Banks / Batteries Japan PSE Certification

In recent years, accidents involving portable lithium-ion storage batteries (i.e., power banks) have occurred frequently. On February 1, 2018, the Ministry of Economy, Trade and Industry (METI) of Japan issued a public announcement regarding a partial revision to the ministerial ordinance explaining the technical standards for electrical appliances and materials. It revised the "Interpretation Concerning the Scope of Electrical Appliances and Materials (March 21, 2012, Commerce Bureau No. 1)" to explicitly stipulate that portable lithium-ion storage batteries (power banks) will henceforth be subject to the Electrical Appliances and Materials Safety Act (DENAN) and handled in accordance with its provisions.

Since February 1, 2019, it is no longer permitted to manufacture, import, or sell any power banks that do not meet the requirements of Japan's PSE regulations.

Since February 1, 2019, portable electrical appliances' lithium batteries and portable lithium-ion storage batteries (mobile batteries) with an energy density of 400Wh/L or more must bear the circular pse mark on the product. Furthermore, they must meet the standard requirements of J62133(H28) (aligned with JISC8712(2015) or IEC62133(2012)) under Appendix 9 or Appendix 12.

Regulation Details

1. Official Website Details

On February 1, 2018, Japan's METI released an announcement revising the scope of lithium batteries subject to the circular PSE control. Lithium-ion batteries for portable appliances and portable battery packs were newly added as subjects of the circular PSE control. A one-year transition period was implemented for these newly added subjects.

3. JJR LAB Tips

According to this revision, in addition to lithium batteries, portable appliances equipped with replaceable rechargeable lithium batteries, and portable batteries (such as power banks, Bluetooth headsets, Bluetooth speakers, electronic cigarettes, etc.) also fall under the scope of the circular PSE control under the Electrical Appliances and Materials Safety Act.

Please note: This newly added product scope still exclusively applies to lithium batteries with an energy density of 400Wh/L or more. Those with an energy density below 400Wh/L remain exempt from the control, just as before.

pse certification Process

1.Application: The applicant provides samples (power bank/battery) and application documents;

2.Testing: JJR LAB conducts sample testing;

3.Confirmation: The applicant confirms the draft report;

4.Issuance: JJR LAB issues the final test report.

Required Documents

1.Application form

2.Product user manual

3.Circuit principle diagram

4.Critical components list

5.Block diagram

6.Electronic label

Sample Requirements:

1.For power banks using cylindrical cells: 37 power bank samples and 98 battery cells are required.

2.For power banks using prismatic pouch cells: 37 power bank samples and 108 battery cells are required.

The testing cycle takes one month.

Japan meti registration

The PSE certification for power banks became mandatory on February 1, 2019, with the testing standard being JIS C 8712 (J62133). Customers must have their products tested at a CNAS-accredited battery laboratory. The Japanese importer will then use the test report to register with METI (Ministry of Economy, Trade and Industry) in Japan.

METI Registration Process:

1. Notification of Business: A declaration by the Japanese importer, which includes manufacturer information, product information, and the date of signature.

2. Approval Certificate: An approval certificate issued by the Ministry of Economy, Trade and Industry of Japan. The importer must use the PSE secondary certificate to register with METI in order to obtain this approval certificate.

3. Registration and Declaration: Japanese buyers must register and declare to Japan's METI within one month after purchasing the goods. Only a Japanese trading company registered in Japan is eligible to apply for METI registration.
