Electrical products sold in Japan fall under the Electrical Appliances and Materials Safety Act (DENAN) and must carry the PSE mark. Specified products, which carry the diamond PSE mark, need assessment by a registered conformity assessment body. Non-specified products, with the circle PSE mark, are self-declared. The Japanese manufacturer or importer must notify METI. Global Approbation prepares testing and documents for your Japanese partner.

| Notification | The business (Japanese manufacturer or importer) notifies METI and takes responsibility for compliance |
| Online sellers | Recent amendments tighten the rules for overseas businesses selling directly to Japanese consumers, including appointing a representative in Japan |

Japan PSE: Frequently Asked Questions
What is the difference between diamond and circle PSE?
Diamond PSE covers specified, higher-risk products that need third-party conformity assessment. Circle PSE covers non-specified products, which are self-declared.
Can an Indian company notify METI?
The notification is made by the business that manufactures or imports in Japan, usually your Japanese importer. We prepare the technical evidence.
Do mobile batteries need PSE?
Yes. Lithium-ion power banks are regulated under PSE.
Is PSE the same as TELEC?
No. PSE covers electrical safety. MIC/TELEC (Giteki) covers radio equipment.
Regulations, standards and deadlines change. Scope, testing route and timelines are confirmed product by product after our applicability review. Global Approbation is a consultancy and does not itself issue certificates; approvals are granted by the relevant authority, accredited laboratory or certification body.
