Published quotes for PSE certification range from about US$1,700 to over US$50,000 for what is described as the same thing. Underneath that spread there is one fixed reference point.
For products in the “specified” category the conformity assessment is carried out by a registered inspection body, and Article 35 requires each domestic body to file its fee calculation method with the Ministry of Economy, Trade and Industry. The Act does not make those filings public, but one body, TÜV Rheinland Japan, publishes its own basis.
How much does PSE certification cost?
There is no single answer, but there is a reference point that can be checked. TÜV Rheinland Japan, a registered inspection body, publishes its calculation basis for conformity assessment fees for specified electrical appliances. The version dated 1 October 2025 lists 26 product items, with estimated fees between JPY 950,000 and JPY 2,300,000. The document states these are estimates for a typically designed sample and may vary with the conditions of a given project.
| Product category (specified electrical appliances) | Fee |
|---|---|
| Earth leakage circuit breakers; portable power generators | JPY 2,300,000 |
| Electric ride-on devices (電気乗物 — a legacy term for electrically driven amusement ride-ons, not road vehicles or e-bikes, which fall outside this scope) | JPY 1,700,000 |
| Refrigerating and freezing showcases; ice cream freezers; vending machines; automatically washing and drying toilets | JPY 1,500,000 |
| Rubber and synthetic resin insulated wires; sheathed flexible cords | JPY 1,400,000 |
| Thermal fuses; socket-outlets; multiple socket-outlets | JPY 1,100,000 |
| Electric storage water heaters; electric heating hot cupboards | JPY 1,050,000 |
| Cartridge fuses; attachment plugs; electric heated toilet seats; electric pumps; electric toys | JPY 1,000,000 |
| Transformers; electric therapeutic bath controllers; AC/DC power supplies | JPY 950,000 |
Source: TÜV Rheinland Japan, Calculation basis of conformity assessment fee for specified electrical appliances and materials, 1 October 2025. Selected rows; the document lists 26 items in total. Figures are one body’s estimated basis, not an industry-wide tariff.
Two things limit how far that table can be pushed. The document states the figures are estimated fees for a typical designed product sample, and sets out two separate mechanisms. Costs may be added by man-hours for component testing or special construction. Fees are calculated separately where Appendix 12 of the interpretive notice applies, where the product has more built-in components or functions than a typical sample, or where the body has no handling record for that product group — a list the document leaves open with “and so on”. The document does not state whether the figures include consumption tax, and does not mention factory inspection costs. And it is one body among several; each files its own basis.
Why do published quotes differ by more than ten times?
Quotes differ mainly because they cover different things and, in several cases, different regulatory categories.
A quotation of US$1,700 for a “diamond PSE” product sits below every figure in the table above — a gap that holds at any USD/JPY rate seen in recent years. That points to one of three things: the product is not a specified electrical appliance, the assessment is not included in that price, or a valid type certificate already exists and is being relied on.
The third case is worth knowing about. Article 9(1) carries a proviso: where a certificate under item (ii) is already held for the same type and the period set by Cabinet Order has not elapsed, the assessment is not repeated. Appended Table 1 sets that period per item at seven years for 27 items, five for 21 and three for 3. A type certified two years ago does not need paying for again.
Category confusion is common enough to appear on the first page of search results. At least one widely ranked English page labels round PSE as the category for complex products and diamond PSE as the one for standard products. The Act works the other way round, and the difference is where most of the cost sits.
Diamond PSE and round PSE: where the cost difference comes from
Diamond PSE covers “specified electrical appliances”, defined in Article 2(2) of the Electrical Appliance and Material Safety Act as those where the structure, method of use or conditions of use make danger or harm particularly likely. The specific items are fixed by Cabinet Order — Appended Table 1 lists ten top-level categories, Appended Table 2 lists twelve for everything else.
Under Article 9, a notified business handling a specified electrical appliance must undergo conformity assessment by a registered inspection body before sale, obtain a certificate and retain it. Article 9(1) sets out two routes: assessment of the appliance itself, or assessment of a test sample together with the inspection equipment at the business’s factory or place of business.
The second route is why factory inspection appears in diamond PSE quotations and not in round PSE ones.
Article 8 — conformity with the technical standards, the business’s own inspection, and retention of the records — applies to every appliance in scope, specified ones included. For products outside the specified list that is the whole of the obligation, and no third-party assessment is mandated. Specified appliances carry Article 9 on top of it, which Article 10(1) confirms by conditioning the mark on Article 8(2) “and” Article 9(1).
Article 27 applies to both, and it is the provision that bites: a business manufacturing, importing or selling may not sell an appliance not bearing the Article 10(1) mark, or display it for the purpose of sale. Article 10(1) itself does not command the mark — it entitles a business that has discharged its obligations to affix one.
Can an agent obtain PSE certification on your behalf?
An agent can prepare, test and coordinate. What an agent cannot do is become the party the Act holds responsible. Article 3 places the notification obligation on the business that manufactures or imports; Article 8 places the technical-standard conformity and record-keeping obligations on that same notified business; Article 9 requires that business to hold the certificate.
Where the importing business is itself located outside Japan, the Act contemplates a domestic administrator rather than a substitute obligation holder: Article 3(1)(ii) defines such a business as a specified import business and requires it to notify the name and address of a person in Japan responsible for preventing the spread of danger and harm caused by the imported appliance. Arrangements that place another company’s notification on your product are a different matter, and carry legal exposure for both parties.
How long does PSE certification take?
No official timeline is published. Providers state figures between roughly 8 and 16 weeks, with longer periods for complex products, but those are self-reported and not traceable to a public source, so they are best treated as indicative only.
What is knowable is which variables move the schedule. Article 9(1) offers the two assessment routes described above, and a route that involves inspecting equipment at the factory adds scheduling that per-unit assessment does not. Whether test data against the technical standards already exists is the other large factor.
JET, one of the main registered inspection bodies, publishes no fee schedule or lead time on its site — only a quotation request. That is consistent with the structure: Article 35 requires each domestic registered inspection body to establish operational rules and file them with the Ministry, and those rules must state the method for calculating conformity assessment fees. The method is filed; the resulting number for a given product is quoted case by case.
What to have ready before requesting a quotation
Whether a product falls inside Appended Table 1 determines almost everything else, so that question comes first. Product specifications, the intended model range, existing test reports against the relevant technical standards, and the factory’s inspection equipment are the inputs a body needs to price the work.
The list of bodies you can approach is published by the Ministry of Economy, Trade and Industry. Its register of conformity assessment bodies covers both domestic and foreign registered bodies. The column that narrows the list is not the name or the address but the category of specified electrical appliances each body is registered for. There are nine domestic registered bodies, and their registered categories differ: JECTEC (Japan Electric Cable Technology Center) holds only the electric wires category; the Japan Quality Assurance Organization holds five; TÜV Rheinland Japan holds nine (checked 14 August 2026). A body that is not registered for your product category will not return a quotation.

Frequently asked questions
How much does it cost to obtain PSE certification?
For specified electrical appliances, the published calculation basis of one registered inspection body, TÜV Rheinland Japan, estimates conformity assessment at between JPY 950,000 and JPY 2,300,000 depending on the product item, as of 1 October 2025. That covers the assessment only, and is one body’s basis rather than a fixed national rate. Products outside the specified list do not require third-party assessment at all.
What is PSE certification?
PSE is the mark required under the Electrical Appliance and Material Safety Act before an electrical appliance may be sold in Japan. Article 27 prohibits selling or displaying for sale any appliance lacking it. Every appliance in scope requires the business’s own testing and record-keeping under Article 8. Specified electrical appliances carry a diamond mark and require third-party conformity assessment on top of that; everything else carries a round mark and stops at Article 8.
Can someone obtain the PSE mark on my behalf?
An agent can handle preparation, testing and coordination, but the Act places the notification, conformity and record-keeping obligations on the manufacturer or importer itself. A specified import business notifies a domestic administrator in Japan for danger-prevention purposes; that is not the same as transferring the obligation to another party.
How long does PSE certification take?
There is no officially published lead time. Providers commonly state 8 to 16 weeks, longer for complex products, but these figures are self-reported. The larger schedule variables are which assessment route under Article 9(1) applies, and whether test data against the technical standards already exists.
What is the difference between diamond PSE and round PSE?
Diamond PSE applies to specified electrical appliances — those the Cabinet Order lists as carrying particular risk — and requires conformity assessment by a registered inspection body before sale. Round PSE applies to everything else in scope, where the business tests against the technical standards itself and retains the records. The mandatory third-party step is why the two differ in cost.
