Flow of Procedures for Notifying Suppliers
1. Confirmation of the Names of Electrical Appliances and Materials
To begin with, confirmation is made of whether the electrical products correspond to "electrical appliances and materials" in the scope of the Act. Generally, products and parts that are connected to an AC power supply for use may fall under Electrical Appliances and Materials.
"Electrical appliances and materials" are designated in Appended Table 1 and 2 of the Order for Enforcement of the Electrical Appliances and Materials Safety Act. "Electrical appliances and materials" are divided into 20 classifications, with each category having an "electrical appliance and material name" and determinations made of the targeted sphere (upper limits of rated power consumption, etc.). There are names of electrical appliances and materials for 457 items (as of March, 2019), with 116 of those items determined to be Specified Electrical Appliances and Materials, which are especially liable to cause hazards and/or threats of troubles occurring. The other items (Non-Specified Electrical Appliance and Materials) are classified into 341 items. The procedures required for Notifying Suppliers differ depending upon the category into which an item is assigned.
Appropriate names of Electrical Appliances and Materials are determined according to the following criteria:
- Determine the name by the intended use, function, etc. rather than by the model name or other general names.
- If two or more functions are provided, consider the names of all the functions.
- To determine whether a product is subject to control under the Act or not, the information about it, such as the structure and ratings are needed.
- Parts packed with the equipment must also be checked.
What item fail to correspond to “Electrical Appliances and Materials”?
All electrical products do not fall under the category of Electrical Appliances and Materials Safety Act.
The Electrical Appliance and Material Safety Law targets electric products directly connected to indoor wiring equipment in general households (defined as being directly supplied with electricity from power outlets). Accordingly, electric product main units operated through detachable AC adaptors*1 and items operated by batteries are not targeted under this category.
Examples:
- Electric product main units operated through detachable AC adaptors (game machines、synthesizers, rechargeable electric shavers, etc.)
- Electric products supplied with electricity through amplifiers (speakers, electric guitars, microphones and other products without built-in amplifiers)
- Certain telecommunications equipment (personal computers*2、PC peripheral equipment, telephones、facsimiles, amateur radio sets, etc.)
*1. AC adaptors themselves are targeted as Specified Electrical Appliances and Materials (DC power source devices).
*2. Some personal computers with TV tuner are targeted
2. Notification of the Commencement of Business to METI
Manufacturers and Importers of the electrical products that fall under Electrical Appliances and Materials (Notifying Suppliers) must notify METI of such business within 30 days from the commencement of the business, in submitting the Notification of Business for Manufacturing/ Importing Electrical Appliances and Materials.
Notifications are required for each of the type classifications of the Appended Table 1 of the regulation for Enforcement of the Electrical Appliances and Materials Safety Act with the matters of notification requirements as follows;
- Address
- Name
- Business commencement date
- Classification of import electrical appliances and materials
- Type classification of electrical appliances and materials in question
- Name, title and address of manufacturer of electrical appliances and materials in question
- Name and address of plant or business establishment
Notifying Suppliers must also notify METI when they transfer such business to someone else, when they change the content of the business, and when they decide to discontinue such business.

3. Obligation to conform to the Technical Requirements
Notifying Suppliers must comply their products with the Ministerial Order to Provide Technical Standards for Electrical Appliances and Materials, in which the technical requirements correspond for all Electrical Appliances and Materials are stipulated as essential requirements.
The concrete technical standards harmonized with these essential requirements are denoted in the Circular Notice of Interpretation for the Ministerial Order to provide Technical Standards for Electrical Appliances and Materials, in which there are two types of technical standards — the traditional Japanese standards in the Appendix Table 1 to 11, and the standards based on IEC standards with some deviations*1) in the Appendix Table 12. While the Notifying Suppliers may freely choose which type of technical standards to apply, it is not possible to select and apply mixture of the technical standards in the Appendix Table 1 to 11 with the standards in the Appendix Table 12 except as otherwise expressly provided.
It is necessary to note that satisfying the foreign standards does not mean fulfillment of the obligation in the Electrical Appliances and Materials Safety Act, even if the products have earned the CE mark or the UL mark.
Type of Electrical Appliances and Materials | |

*1) Because grounding outlets are not common in Japan, and the earthing system for electric power distribution lines is different between Japan (TT earthing system) and Europe (TN earthing system), it is necessary to ensure safety concerning Electrical Appliances and Materials. On the other hand, the standards for protection against electrical shocks have been eased because of the lower power supply voltage. These are the major reasons for these deviations.
No particular stipulations are made with regard to the methods to use for compliance conformation to the technical standards. Generally speaking, however, because of the difficulties involved for importers in confirming compliance with technical standards on their own, this obligation may be fulfilled through methods that include the following;
- Request that testing be performed by overseas manufacturers, with the said test reports obtained and compliance confirmed.
- Request that testing be performed by conformity assessment bodies.
Exemption of Standards Compliance
When the electrical appliances and materials should be utilized for the specified purposes, the technical standard compliance obligation may be waived with approval from the Minister of Economy, Trade and Industry. Such approval can be obtained for the products to be sold to foreign travelers (products that are in compliance with foreign standards and used in other countries), the products used in special locations, the antique lighting stands, etc.
4. Obligation to Conduct Self-inspections
Notifying Suppliers are obliged to conduct Self-inspections of Electrical Appliances and Materials to confirm their conformity to technical requirements, as well as preserve records of such inspections for three years, in accordance with the Regulation for Enforcement of the Electrical Appliances and Materials Safety Act.
There are difference in the methods of Self-inspections between the Specified Electrical Appliances and Materials (Category A) and the Non-Specified Electrical Appliances and Materials (Category B).
Self-inspections for the Specified Electrical Appliances and Materials
The Self-inspections for the Specified Electrical Appliances and Materials (Category A) consist of three types of inspection;
- Inspection conducted in manufacturing processes
This inspection must be conducted constantly with respect to the structure, material, and performance of said Specified Electrical Appliances and Materials by a method deemed appropriate for ensuring conformity to technical requirements according to the manufacturing method. - Inspection conducted on finished products
This inspection must be conducted on every finished products, in other words, on a product-by-product basis. Test items of the inspection differ depending on the type of Specified Electrical Appliances and Materials as following table.
Specified Electrical Appliances and Materials | Test Items | |
---|---|---|
Fuses (thermal fuses with a container, excluding fuses with a container that is not charged) | Appearance | |

Self-inspection for the Non-specified Electrical Appliances and Materials
In case of the Non-Specified Electrical Appliances and Materials (Category B), it is adequate only to conduct inspection on finished products as the obliged Self-inspection. This inspection must be conducted on every finished products, in other words, on a product-by-product basis. Test items of the inspection differ depending on the type of Non-Specified Electrical Appliances and Materials as following table.
Non-Specified Electrical Appliances and Materials | Test Items |
---|---|
|

Self-inspection Records
Notifying Suppliers are required to custody the inspection records including following six items.
- Product name and classification by product type of Electrical Appliances and Materials and outline of the structure, material, and performance
- Date and place of inspection
- Name of the person who conducted inspection
- Quantity of Electrical Appliances and Materials inspected
- Inspection method
- Inspection results
The inspection records can be prepared in any form as long as the form includes the necessary items stipulated by the Act. However, the record should show a relationship with product specifications, inspection specifications (test methods), criteria for judgment results, etc. Such a record does not satisfy the legal requirements like just states “Conforms to the Act,” or states that inspection has been passed in appearance, dielectric strength test, and energization test.
In the case of importer that does not own inspection equipment, outsourcing of the self-inspections is accepted. However, because the legal responsibilities under the Electrical Appliances and Materials Safety Act pertain fully to the importer, steps must be taken to keep the inspection records at the importer, be prepared to immediately submit those records to the METI or other authorities upon request and have the capacity to explain the compliance confirmation.
5. Obligation to Undergo Conformity Assessment on the Specified Electrical Appliances and Materials
Notifying Suppliers must fulfill the following obligations by the time such Electrical Appliances and Materials are sold.
However, conformity assessment can be omitted for other Electrical Appliances and Materials of the same product type if the certificate of conformity is valid or if an official copy of the equivalent of the certificate of conformity from overseas manufacturers is retained.
- Obligation to undergo conformity assessment of Specified Electrical Appliances and Materials by the registered conformity assessment body (Registered CAB).
- Obligation to obtain and preserve a valid certificate of conformity
The Registered CAB is conformity assessment body that has been registered by the government to conform to International Standard (ISO/IEC 17065) for its capability. As a neutral and fair third party, the Registered CAB verify conformity with the Technical Requirements through testing the samples of products submitted by Notifying Suppliers, and verify suitability of the inspection equipment at the factories.
