Hello. It is the moat of the caretaker.

I have explained the outline of the system for PSE, PSC, radio wave legal aptitudes, etc., and the meaning of obtaining certification, but this inspection procedure is a particularly selling point of our company.

This is because there are many pages that explain the inspection procedure while quoting pages such as the Ministry of Economy, Trade and Industry, but in the end, it is subjective to the last, but I get the impression that you have never actually done a test such as PSE, PSC, or radio wave technical aptitude test.

If you have actually done the inspection, the expression used while quoting the page will be a word that is in line with practice, and in a word, you can immediately tell whether it is real or not.

Our company's purpose is not to explain the system, but to find out how to pass certification.

Therefore, we would like readers who are interested in authentication to grasp only the minimum points and leave the details to the rest.

This time, I will explain the flow of PSE certification, and from the next time onwards, I will write about the flow of PSC certification and Radio Law certification.


Pse certification flow

Citation: Ministry of Economy, Trade and Industry website "Electrical Appliance and Material Safety Law _ Flow of Notification and Procedures"

Start with the PSE (Electrical Appliance and Material Safety Act) inspection procedure. It cites the flow of the Ministry of Economy, Trade and Industry.

Business act

I will omit the explanation of whether or not the electrical appliances are subject to PSE.

When you are subject to PSE, the chart is divided on whether or not to sell the product (business act), but if a series of inspections etc. have already been completed by someone, it is also possible to sell it as it is.

Sales at Mercari may fall under this category.

However, such a pattern is almost impossible, so basically if you are going to do a business act, you will proceed to the next "business notification".

Business notification

The Ministry of Economy, Trade and Industry page says, "If you want to start a new business, you must submit a 'business notification' to the Bureau of Economy, Trade and Industry within 30 days of the start.", but I think that there are no people who see this page who start a "manufacturing" business, so I will talk about it on the premise of "import" business.

The PSE test takes at least 45 days, so it is possible to actually submit a notification in time even after all the inspections have been completed, and I think that is more reasonable.

Samples prepared are attached to the website of the competent Bureau of Economy, Trade and Industry (an organization that accepts documents to be applied to the Ministry of Economy, Trade and Industry). If necessary, it is also possible to ask an expert such as an administrative scrivener to create it.

Confirmation of standard compliance

To put it simply, it is a sample test performed on an inspection agency.

The flow is very simple, but depending on the choice of which inspection institution to use at this time, the inspection cost will vary greatly.

For example, it takes time and effort to send samples to Japan inspection agencies even though the production area is China. Also, while Chinese inspection institutions are basically cheaper, I think it is simply a waste that we cannot make that choice just because we do not know how to utilize them overseas.

On the other hand, there are also certifications of the most difficult degree that are only recognized by Japan inspection organizations, so it is necessary to use Japan inspection agencies.

The important thing is to choose the most suitable inspection organization that suits your company's plan, and we also accept such consultations, so please do not hesitate to contact us.

Going back to the subject, it is necessary to submit technical documents such as specifications and product schematics as well as samples to inspection organizations.

Also, in the case of overseas production, the sample to be submitted is out in one shot if it does not have Japan specifications.
Be careful not to submit default samples without knowing it.

If you look only at the flow, such a thing is not written, so it is necessary to understand that in advance and negotiate documents with the factory that will respond to the inspection.

What kind of documents are necessary in the first place? Can we communicate it ourselves? If you are worried, please do not hesitate to consult us.

The required documents vary depending on the product, but our specialized staff will explain to the factory in Chinese and English, so you can be entrusted with work with peace of mind.

Specified electrical appliances and materials_Conformity inspection

As I have mentioned before, PSE is classified into specified electrical appliances and materials (commonly known as rhombic PSE) and non-specified electrical appliances (commonly known as round PSE).

Conformity inspection means production plant inspection.

In other words, specific electrical appliances and materials require a production plant inspection, and production plant inspections are not required except for specified electrical appliances, and once the sample inspection is completed, the next manufacturing and import step will proceed as it is.

It is a little difficult to read from this flow, but whether to certify with either a specific electrical appliance or a specific electrical appliance material or a specific electrical appliance material is known from the early stages, and it must be known.

This is because, for example, if the product you are considering certification is a specified electrical appliance material, you must dispatch inspectors to the production plant, and since the number of items other than product inspection will increase, it is necessary to grasp what you will inspect.

There are various costs involved in certification, but when considering the cost-effectiveness of being able to keep down where it should be suppressed, it seems that it is worth considering which one to choose.

In addition, factory inspection is Japan inspection agency confirms whether the factory has costly production equipment, etc. when producing PSE-related products, whether it is a factory or a Chinese factory.

There will be no problem if the factory is doing PSE inspection many times, but if you are going to undergo PSE inspection for the first time, it cannot be denied that there are severe parts without consulting by a third party.

It is also possible that a sample inspection has passed, but the factory inspection has failed.

Regardless of whether it is a Japan factory or a Chinese factory, we also provide a service called pre-factory inspection guidance. We also provide on-site guidance at the factory as necessary, and it has become a service that has been very well received, especially by customers who are PSE certified for the first time. Please feel free to consult us about this.

Manufacturing and import

After all the certification tests are over, I hope that you will be able to manufacture and import in a sunny manner.

In addition, I think that the PSE certificate will be issued by this time, so even if you do the "business notification" mentioned above at this timing, it will be enough in time.

Voluntary inspection

For details, I wrote before, "PSE, PSC, Metrology Law, Radio Law Conformity, etc. are not all completed once certification is completed. Even after certification, voluntary inspections etc. are required, and there are also trial purchase tests by related ministries and agencies." Please refer to the article "What is PSE and PSC Voluntary Testing?"

Basically, I think that factory inspection reports are fine, but we also check whether they can be presented to the Ministry of Economy, Trade and Industry and prepare our own format.


Actually, this is the part where we receive the most inquiries from customers.

We receive a lot of consultations with the content of "Even though we have certified with our own money, we are worried that the Chinese factory will divert the certified product to another company or sell it without permission at our company".

That's exactly how you feel.

This can also be prevented with a certain amount of know-how, but the most important point is to control all authentication at your company I believe that it is.

For example, if you can pay for certification but do not know the detailed technical part well, if the certification practice is left to the Chinese factory, as mentioned above, there is a high possibility that the factory will start doing arbitrary things after certification.

We are designing the process so that the certification can proceed under the leadership of the client, and we also accept consultation on the control of certified products, so please do not hesitate to contact us.


I think that the company can sell this freely, but if necessary, it is also possible to consult with us about sales channel development.

How much does it cost to authenticate?

It's a question I get asked a lot, and it's not that I don't teach it in a mean way, but it's really different from product to product, so I can't answer it easily.

As a question, I am asked roughly, "How much is PSE certification?", but there is a difference between the specified electrical appliances and materials mentioned above and other specified electrical appliances, and there is a big difference in the presence or absence of factory inspection by the inspection institution and the location of the factory, so I would be grateful if you could have such information when you first ask a question.

Our strengths: Estimates are possible without technical documentation

Even so, I think that some market views are also necessary after all.

Depending on the thing, excluding our fee of 200,000 yen (excluding tax), about 300,000 yen to 1.5 million yen will be the general market price. It varies greatly depending on the thing, so I think that you can contact us first.

In addition, if you use an inspection institution in China (overseas), the inspection cost itself will be tax-exempt.

Our strengths include many years of experience and experience, so we may be able to estimate roughly even without technical documentation. Japanese inspection agencies are often said to need technical materials for estimates, and it may take time just to prepare the materials.

Adapter factories often have certified specific electrical appliances in-house

As a bonus, for AC adapters (commonly known as DC power supply units), there are many cases where the factory has already certified specific electrical appliances and materials.

We can also search for the AC adapter that suits your product and arrange the necessary conformity certificate and counterpart.

Customers want to know how to pass the system, not explain the system

Again, what customers want to know is not an explanation of the PSE system, but how to pass the PSE exam.

From the perspective of an expert, this page may also have objections and objections as if it were a corner of a heavy box, but at least we have written it based on our company and our customers' experience as "minimum necessary information to pass certification".
