Question 1: What kind of method shall be applied to the calculation of the Customs Value of the import goods?
The "Transaction Value Based Method (Actually paid or payable + Additional costs)" under the Japan Customs Tariff Law is the primary method that should be initially considered for application.
Please bear in mind that the Invoice Value is not always equal to the Customs Value.
This Primary method is to calculate the Customs Value based on the "Value of the Import Transaction".
The definition of "Value of the Import Transaction" is that, when the import transaction of the import goods has made, the price actually paid or payable regarding the import transaction by the buyer to or for the benefit of the seller for the import goods, and adjusted by certain additional costs such as transportation costs, to the extent that such costs have not been included in the price actually paid or payable for the imported goods.
Customs value = Transaction value = Actually paid or payable※1 + Additional costs※2
※1: The price actually paid or payable is the total payment made or to be made by the buyer to or for the benefit of the seller for the imported goods. It includes a settlement by the buyer whether in whole or in part, of a debt owed by the seller and other indirect
payment for the seller by the buyer. In principle, the price actually paid or payable shall not include the following charges or costs, provided that they are distinguished from the price actually paid or payable for the imported goods:
1) Charges for construction, erection, assembly, maintenance or technical assistance is undertaken after importation of the imported goods;
2) Transportation costs after importation;
3) Duties and taxes imposed on the imported goods in Japan.
However, if the price actually paid or payable will not be able to be grasped by the whole amount including the above costs, then it shall be the total amount including such costs.
※2:For instance, transportation fee and insurance fee (CIF basis), commissions, etc.
In case of calculating the Customs value based on the transaction value, the calculation of the customs value should be based on invoice and other documents which are able to verify the price actually paid or payable of the imported goods and to be adjusted certain additional costs such as the transportation costs.

Japanese Customs System Reform: Clarification of Importer Definitions
Starting October 1, 2023, Japanese Customs has instituted a pivotal reform aimed at addressing the issue of foreign sellers improperly designating third parties (such as forwarders or customs agents) as importers.
This revision necessitates foreign corporations to utilize an Attorney for Customs Procedures (ACP) to assume the role of Importer of Record (IOR) directly in many cases. The practice of merely nominally appointing another entity as the importer is no longer feasible.
Notably, foreign corporations that act as importers themselves, through the engagement of ACP, are eligible for Japan Consumption Tax (JCT) benefits. (link: Consumption Tax Treatment and Benefits of Using ACP).
As a dedicated ACP firm, we ensure compliance with the law to facilitate correct import procedures, allowing you to trust us with your importation requirements confidently. We are eager to engage in further discussions with you.
Revisions Effective October 1, 2023:
Definition of the Importer
- Regarding a cargo imported under import transaction, an importer is equivalent to “a person who imports a cargo” defined in Article 6-1 (1), General Notification of the Customs Act. ..... This means, the Consignee, etc., in the case of imports conducted through normal transactions between an overseas seller and a Japanese buyer
- In the cases other than above, an importer is a Person Having the Right of Disposal of the import cargo at the time of import declaration. If there is another person who acts on the purpose of the import*, that person is also included :In case of a cargo imported:
- under lease contracts, a person who rents and uses the cargo.
- for consignment sales, a person who sells the cargo in the name of himself/herself (consignee) by accepting the commission.
- for processing or repairing, a person who processes or repairs the cargo.
- for disposal, a person who disposes the cargo.Importer Defined as the “Person Having the Right of Disposal”
One of the most notable aspects of the amendment is the clarification that the “person having the right of disposal” is regarded as the importer under Japan Customs law. The term “right of disposal” is similar to ownership, but not identical. Although there is no explicit definition in the customs-related legislation, according to Japan Customs, it refers to the authority to decide how the goods will be handled after being released into Japan—for example, whether to sell the goods or to enter into a sales contract.
