Three Tickets Into the Japanese Market: PSE, PSC and Food-Contact Materials

Japan has one of the densest sets of rules in Asia, but its compliance requirements are not vague: once you identify which law a product falls under, who the obligated party is, and which marks and documents are required, the path becomes clear. The three gates that cross-border e-commerce and store-based sourcing run into most often sit in electrical safety, consumer product safety and food-contact materials.

Ticket one: PSE (Electrical Appliances and Materials Safety Act)

The Electrical Appliances and Materials Safety Act (commonly known as the DENAN Act) divides electrical products into two groups. Specified Electrical Appliances and Materials cover a little over one hundred categories with higher risk (for example certain power adapters, chargers and electric heating appliances); these must undergo conformity inspection by a registered conformity assessment body in Japan and carry the diamond PSE mark. Categories outside the specified list, more than three hundred of them, allow the manufacturer or importer to self-confirm conformity with the technical standards and carry the circle PSE mark.

The critical point is who is obligated. The legal duty sits with the manufacturing business or importing business inside Japan: it must submit a business notification to the Ministry of Economy, Trade and Industry, retain inspection records and test reports, and ensure the labelling is complete (business name, rated values, year of manufacture and so on). For an overseas factory this means there must be a Japanese importer carrying that obligation, or a qualified agent completing it. Whether that chain is connected should be confirmed at the sampling stage, otherwise the goods cannot be legally sold even after they reach the port.

Ticket two: PSC (Consumer Product Safety Act)

The Consumer Product Safety Act targets consumer products that may cause personal injury in use. Typical categories designated as specified products requiring the PSC mark include toys for children under 36 months, baby beds, lighters, pressure cookers, motorcycle helmets, climbing ropes and oil bath units. Some of these also require conformity inspection by a registered inspection body, making them a double gate.

Toys are the category most often underestimated here. If a product is positioned for children under three, it faces both PSC and the ST mark requirements of the Japan Toy Association. The ST mark is a voluntary certification scheme of the association, but mainstream retail channels essentially treat it as a precondition for shelf space. Labelling the applicable age is therefore not a marketing copy issue but a compliance classification issue: writing the age as three and above to sidestep PSC, once judged to be improper labelling, brings consequences far more serious than doing one more certification.

Ticket three: food-contact materials

Under the Food Sanitation Act, requirements for utensils, containers and packaging moved to a positive list system for synthetic resins from June 1, 2020, allowing only substances listed in the list, and the transition period ended on June 1, 2025. Tableware, food storage boxes, drinking cups, kitchen tools and food packaging are all covered, and materials such as silicone, melamine, PP and PET all fall within scope.

In practice, three things matter. First, the compliance declaration for the material: upstream resin or moulding suppliers must provide proof that the material conforms to the positive list. Second, migration test data: parts in direct contact with food must be tested under conditions matching their use (fatty, acidic, alcoholic, high temperature). Third, business registration: manufacturing or importing utensils, containers and packaging requires a business notification as prescribed. A single generic food-grade test report is usually not enough to pass a Japanese importer's compliance review.

Beyond the three tickets: radio and energy efficiency

Products with wireless functions (Bluetooth, Wi-Fi) also need a technical standards conformity certificate under the Radio Act, that is the technical conformity mark (技適マーク, giteki mark); products with lithium batteries face additional UN38.3 and transport assessment requirements for air freight. If a product involves energy efficiency labelling (some home appliances, for example), the labelling obligations under the Energy Conservation Act must also be checked. These are usually handled in parallel with PSE, and the time cost should be added up together when scheduling.

Getting it done: build compliance into the sampling schedule

A four-step approach is recommended. Step one, make the legal classification at the product selection stage and specify which of PSE, PSC and food-contact requirements the product falls under, or how many of them. Step two, secure the Japanese domestic obligated party and confirm who bears the business notification and labelling duties. Step three, commission a testing body with the corresponding qualification, and write consistency control between test samples and mass production samples into the order terms. Step four, design labels and instructions so that placement, language and content meet the requirements, and complete document archiving before the first shipment arrives.

Compliance cost must go into the quotation in advance. A PSE or PSC test is usually charged per project, food-contact migration testing is charged by combination of material and condition, and multi-material products often stack up. When ESTROUTE helps clients connect with Japanese channels, the compliance assessment is normally completed before pricing, so that clients are not caught in the passive position of having agreed a sample deal only to see cost double because of certification.

FAQ

What is the difference between the diamond PSE mark and the circle PSE mark?

The diamond PSE mark applies to Specified Electrical Appliances and Materials (a little over one hundred higher-risk categories) and requires conformity inspection by a registered conformity assessment body in Japan. The circle PSE mark applies to categories outside the specified list (more than three hundred) and allows the manufacturer or importer to self-confirm conformity with the technical standards.

Can an overseas factory complete Japanese compliance on its own?

In most cases no. The obligated party for PSE and PSC is the manufacturer or importer within Japan, who must file the business notification and keep inspection records. There must therefore be a Japanese domestic entity carrying that responsibility, and the overseas factory has to cooperate with it.
