Customs Valuation: Determining the Import Declaration Value
Please note that an invoice value cannot automatically be used as the customs value for import declaration purposes.
Primary determination method
In general, the primary method of customs valuation in Japan is the transaction value method, which is based on the price actually paid or payable for the imported goods, adjusted to a CIF basis. This is referred to as the principal method of determination under Article 4, Paragraph 1 of the Customs Tariff Act of Japan.
However, this method can be used only where there is an “import transaction” under the Customs Tariff Act. In general, an “import transaction” requires both of the following conditions:
- There is a sale/purchase transaction for the goods being imported into Japan; and
- The buyer is located in Japan.
For example, where goods are sold by an overseas seller to a Japanese buyer/importer, and the Japanese buyer imports the goods into Japan, the CIF-adjusted sales price may generally be used as the declared customs value.
On the other hand, if a foreign importer purchases goods from an overseas supplier before importing them into Japan, that overseas purchase price cannot normally be used as the customs value for the Japanese import declaration. This is because there is no import transaction involving a buyer located in Japan.
If your case does not meet the above requirements, the customs value must be determined using one of the alternative valuation methods

Customs duty is generally calculated by multiplying the customs value by the applicable duty rate, which varies depending on the HS code of the goods.
Import consumption tax is generally calculated by multiplying the customs value plus customs duty by the applicable consumption tax rate, which is currently 10%.
Exceptional determination method
In cases where a non-resident company imports goods into Japan and the above requirements are not met, the primary valuation method cannot be applied. In such cases, simply using the invoice value as the customs value is not appropriate.
To determine the customs value in these situations, it is necessary to apply one of the alternative valuation methods provided under Japanese customs law.
Several methods may be considered under the alternative valuation framework, including:

- Transaction Value of Identical or Similar Goods Method: If you have previously imported goods that possess identical or similar conditions to the goods in question, the transaction value of those goods can be used.
- Domestic Selling Price Method (Deductive Method): If you can identify the sales price (can be an estimated sales price), the domestic selling price method can be employed.
- Cost of Production Method (Cost plus Method): If the exporter is a manufacturer and can provide production costs, the production cost method may be applicable.
If none of the above methods are suitable, “Other methods” are utilized as a flexible determination method, taking into account the calculation methods mentioned earlier.
In the practical scene, most of the cases we use this “Other methods” which is a determination method in a flexible way through considering the previously mentioned calculation methods.
One example of this “other methods” approach is the valuation method commonly used for Amazon FBA import cases. This is a type of deductive method based on the estimated selling price in Japan.
For more details, please see: “Amazon FBA Japan: Import Deductive Valuation Method.”
Avoiding Customs Valuation Problems
In recent times, there have been numerous instances of trouble arising from incorrect Customs Value settings.
In the worst-case scenario, goods may fail to clear customs, resulting in significant detention fees and eventual return shipment.
At ACP Japan, we specialize in establishing appropriate Customs Values. We can assist in conducting consultations with Japan Customs on behalf of our clients, effectively avoiding any potential issues down the line.
For Amazon’s FBA business, there is a recommended calculation formula for the declaration value. If you would like to learn more about it, please don’t hesitate to contact us!
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
Under Japan Customs practice, the importer is determined as follows.
For cargo imported under an import transaction, such as a normal transaction between an overseas seller and a buyer in Japan, the importer is the buyer in Japan, namely the person who imports the cargo as referred to in Article 6-1(1) of the General Notification of the Customs Act.
In cases other than the above, the importer is the person who has the right to dispose of the import cargo at the time of import declaration.
In addition, another person acting for the purpose of the import, such as those listed below, may also be treated as the importer:
- for cargo imported under a lease contract, the person who rents and uses the cargo;
- for cargo imported for consignment sales, the trustee who sells the cargo in their own name under the consignment arrangement;
- for cargo imported for processing or repair, the person who processes or repairs the cargo; and
- for cargo imported for disposal, the person who disposes of 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.

Japan Qualified Invoice System and Compliance JCT (Japan Consumption Tax)
Recently, many companies have been registering as Qualified Invoice Issuers for Japanese Consumption Tax (JCT) due to the new invoice system introduced in October 2023. This new system is similar to the EU’s VAT invoice system.
After October 2023, your Japanese customer can’t claim input JCT tax credits unless the sellers(suppliers) issue a qualified invoice that is written a JCT number. To issue a qualified invoice, sellers(suppliers) need to be a taxable entity and get a JCT number.
Before October 2023:
Any customer (Company-B) who paid for goods or services could deduct input JCT regardless of whether the seller (Company-A) was registered for JCT. There was no requirement to verify the tax status of the seller.
After October 2023:
Any customer (Company-B) can only deduct input JCT if Company-A, the seller, is registered and can provide a qualified invoice with a JCT registration number. If Company-A cannot issue such an invoice, Company-B may choose not to continue purchases from them.
If Company-A sells only to consumers and not businesses, it may not need to issue qualified invoices since consumers typically do not claim JCT tax returns.

Once Company-A obtains a JCT invoice registration number, it becomes a taxable entity required to file JCT returns regularly.
For non-resident entities (Company-A) importing and selling in Japan, the standard procedure involves three steps:
- Pay import JCT to customs: 10% of the import customs value.
- Collect JCT from customers in Japan: 10% of the sales price.
- File a JCT tax return and pay the net JCT to the tax office.
If Company-A paid the import JCT as the importer using an Attorney for Customs Procedures (ACP), they need only pay the net amount of sales JCT minus import JCT.
If Company-A paid the import JCT but was not the importer, they must pay all the collected sales JCT without deducting the import JCT.
Therefore, using an ACP to act as the Importer of Record (IOR) is crucial for managing JCT deductions and refunds. If another company acts as the IOR, you cannot deduct the import JCT, resulting in significant costs.
We strongly recommend using our ACP services to ensure you can act as IOR, optimizing your JCT handling. Our team has extensive experience helping clients become importers and successfully manage their JCT responsibilities. You can rely on our expertise to navigate these complexities.
