Japan Product Safety Four Laws Revision — Effective December 25, 2025! Cross-Border Seller Emergency Response Guide
At the end of 2024, Japan's Ministry of Economy, Trade and Industry (METI) officially released major revisions to the four product safety laws (Electrical Appliance and Material Safety Law, Consumer Product Safety Act, Gas Business Act, and LP Gas Act). The core change: for the first time, overseas cross-border e-commerce operators are brought under legal supervision — meaning Chinese sellers on Amazon Japan, Rakuten, and other platforms must formally comply with Japanese regulatory requirements.
Effective date of new regulations: December 25, 2025
With less than 7 months until full enforcement, this article outlines a complete compliance roadmap for businesses.
Overview of the Four Product Safety Laws
These four revised laws together form the backbone of Japan's consumer product safety regulatory system:
| Law Name | Abbreviation | Scope | Key Requirements |
|---|---|---|---|
| Electrical Appliance and Material Safety Law | PSE Law | Electrical products (457 designated items) | PSE mark + technical standards conformity certificate |
| Consumer Product Safety Act | SG/CSC Law | Consumer products (specified products: baby cribs, helmets, climbing ropes, etc.) | SG/PSC mark + conformity inspection |
| Gas Business Act | PSLPG Law (Gas) | Gas appliances | PSLPG mark + technical compliance |
| LP Gas Act | PSLPG Law (LPG) | Liquefied petroleum gas equipment | Technical standards conformity |
Focus: Electrical Products Covered by the PSE Law
The PSE Law has the broadest impact of the four. Its 457 regulated products fall into two categories:
| Category | Number of Products | Compliance Requirement | Representative Products |
|---|---|---|---|
| Specified Electrical Appliances (Category A) | 116 items | Mandatory third-party certification (METI-registered bodies) | Power adapters, electric water heaters, electric fans |
| Non-Specified Electrical Appliances (Category B) | 341 items | Self-confirmation + self-retention of technical documents | Phone cases (with battery), USB charging cables, LED lighting |
Most cross-border e-commerce sellers deal in Category B products (341 items) and should focus on self-confirmation and technical document compliance requirements.
Core Concept: Designated Import Operator (Tokutei Yunyū Jigyōsha)
The most important new concept in this revision is the Designated Import Operator, defined as:
"An overseas operator who sells electrical appliances (foreign-manufactured goods) to general consumers in Japan via the internet, meeting conditions specified by METI ministerial ordinances."
Simply put: any Chinese seller who sells products regulated by the four laws to end consumers in Japan through e-commerce platforms is classified as a Designated Import Operator.
Obligations as a Designated Import Operator
| Obligation | Description |
|---|---|
| Appoint a Japan Agent (Domestic Administrator) | Must designate a responsible representative based in Japan as the METI contact point |
| Technical Standards Conformity Confirmation | Category B products require self-confirmation of conformity to Japanese technical standards; Category A requires third-party certification |
| Marking Obligation | Affix PSE/SG/PSLPG marks and importer information on the product or packaging |
| Document Retention Obligation | Retain technical conformity documents for at least 3 years |
| Incident Reporting Obligation | Report major product accidents to METI |
Japan Agent (Domestic Administrator) System Explained
The Domestic Administrator (commonly known as "Japan Agent") is the most critical compliance element under the new four-law regime. According to METI ministerial ordinances, Designated Import Operators must designate a natural person or legal entity within Japan as the Domestic Administrator.
Duties of the Japan Agent
- Receive and forward METI supervision and inspection notices
- Retain copies of technical standards conformity confirmation documents
- Report incidents to METI when they occur
- Serve as the contact point for Japanese consumers (product recalls, etc.)
Japan Agent Options
| Option | Cost (JPY/year) | Applicable Scenarios |
|---|---|---|
| Japan agency service provider | 50,000-150,000 JPY | Most SME sellers |
| Japan branch/subsidiary | Self-funded by enterprise | Already have a presence in Japan |
| Japanese partner (importer) | Depends on agreement | Have stable Japanese partner |
Important note: The Japan Agent is not merely an "address holder." If a product safety incident occurs, the Japan Agent may bear joint legal liability. Choosing a reliable, professional Japan Agent service is critical.
METI Registration Process
For Category B electrical products, the core compliance registration process:
Step 1: Confirm the Product Is Regulated
Check the METI list of designated electrical appliances to determine if your product requires the PSE mark. It is recommended to make this determination early in product development.
Step 2: Technical Standards Conformity Confirmation
For Category B products, companies must test and evaluate products against Japanese electrical appliance technical standards. This can be done through:
- In-house testing (requires Japanese standards testing capability)
- Commission a CNAS-accredited laboratory in China to issue test reports
- Commission a locally accredited laboratory in Japan
Step 3: Appoint a Japan Agent
Complete Japan Agent appointment and report to METI before the Domestic Administrator system takes effect. Must be completed by December 25, 2025.
Step 4: Affix the PSE Mark to Products
Label the following information on the product or packaging:
- PSE mark (diamond for Category A/specified products, circle for Category B)
- Notifying business operator name (importer name)
- Rated specifications (voltage, power, etc.)
Step 5: Document Archiving
Retain technical conformity confirmation documents, test reports, etc. for at least 3 years.
Penalties for Violations
| Violation | Penalty |
|---|---|
| Selling products without PSE mark | Up to 1 year imprisonment or fine up to 1,000,000 JPY |
| Failure to appoint Japan Agent | Business improvement order → business suspension order |
| False marking | Up to 1 year imprisonment or fine up to 1,000,000 JPY |
| Failure to retain technical documents | Business improvement order |
| Non-cooperation with METI inspection | Fine (up to 100,000,000 JPY for corporations) |
METI has the authority to conduct random inspections of imported products in coordination with customs. The risk of non-compliant products being detained or destroyed by customs must also be taken seriously.
Timeline and Implementation Recommendations
| Timeline | Action Items | Urgency |
|---|---|---|
| June-July 2025 | Complete product category determination; confirm if within four-law scope | Critical |
| August-September 2025 | Begin technical standards conformity confirmation (testing); appoint Japan Agent | Critical |
| October-November 2025 | Complete PSE/SG mark application; METI registration | High |
| December 25, 2025 | New regulations take effect; full enforcement begins | — |
Frequently Asked Questions
Q: I sell phone cases on Amazon Japan — do I need PSE certification?
A: If the phone case contains a built-in battery or charging function (e.g., battery case), it falls under Category B of the PSE Law, requiring technical standards conformity confirmation and PSE marking. Plain protective cases without electrical functions do not.
Q: Do all cross-border sellers need to appoint a Japan Agent?
A: Only if you qualify as a "Designated Import Operator" (i.e., selling imported electrical products/consumer goods directly to Japanese consumers). If you sell through a Japanese importer (You → Japanese Importer → Japanese Consumer), the Japanese importer bears PSE responsibility — but this is uncommon in the platform model.
Q: Can I use a friend or relative as the Japan Agent?
A: The law does not prohibit it, but the Japan Agent bears actual legal and administrative responsibilities (receiving METI notices, cooperating with inspections, incident reporting, etc.). It is recommended to use a professional Japan Agent service provider to mitigate risk.
Q: What documents are required for Category B product self-confirmation?
A: Key documents include: product technical specifications, test reports (demonstrating conformity to Japanese electrical appliance technical standards), circuit diagram/BOM, product photos, nameplate/PSE mark design drafts, etc.
