Customs Valuation in Japan – overall structure


Basically the import consumption tax and customs duties are imposed when import declaration is made, those are calculated by multiplying the import declaration price by the tariff rate. The determination of the import declaration price should be decided by the importer under him/her responsibility.

The import declaration price (customs value) is determined by the following steps.

※Please note that this article is drafted mainly aiming to make understandings as capturing big picture, therefore it does not describe details regarding Japan Customs Tariff Law.

Sale transaction exists between importer and exporter YES → [1] Principle determination method
  NO ↓
Already imported goods which meet the identical or similar conditions of the import goods YES → [2] Use of the transaction value of identical or similar goods method
  NO ↓
Able to identify the sales price and costs incurred in Japan YES → [3] Use of the domestic selling price method
  NO ↓   ↕  selectable [3] or [4]
Exporter is a manufacturer and able to provide production cost YES → [4] Use of the production cost method
  NO ↓
[5] Other methods





[1] Principle determination method

In principle, if the import is made based on the import transaction※1, we can use the principle determination method.

※1:Import transaction is a transaction that a buyer in Japan makes a sale transaction with an overseas seller for shipping the goods to Japan, and the goods actually arrive in Japan.


The Customs Value is the transaction price paid by the buyer to the seller, plus the additional expenses.

Customs value  =  Transaction price  =  Actually paid or payable※2  +  Additional expenses※3

※2: The Customs value of imported goods shall be the transaction value, that is the price actually paid or payable by the buyer to or for the benefit of the seller for the imported goods relating to the import transaction.

※3:For instance, transportation fee, insurance fee, commissions.


The principle determination method cannot be used for certain import cases, for instance, if there is no sales transaction, goods are traded free of charge, etc. In these cases, the following alternative methods are applied for the determination of the Customs Value.


[2] Use of the transaction value of identical or similar goods method


If you already imported identical or similar goods, the customs value can be determined by using those goods if conditions raised by the following can meet.

Conditions of being identical goods

  1. The imported goods should have exported approximately within one month before or after the export date of the targeting import goods.
  2. The imported goods should have produced in the same country as the targeting import goods.
  3. The imported goods should have an identical shape, quality and value as the targeting import goods.

Conditions of being similar goods

  1. Same requirement as previously mentioned 1.2. in identical goods.
  2. The imported goods has similarity in terms of shape, component and functions. And it should be interchangeable with the targeting import goods.


(2)Documents need to prepare

  • The materials to prove the identity and similarity. e.g. specification document, photos.
  • The customs clearance documents related to the referenced identical / similar goods, such as invoice, import permissions.



[3] Use of the domestic selling price method


In case customs value cannot be determined by the previous methods, the determination method [3] using of the domestic selling price or [4] using of the production cost can be applied. Upon request by importer, the priority of between [3] and [4] are selectable.

If we look at the [3] use of the domestic selling price method, the calculation is made by follows.

Customs value = Domestic selling price※4 - (general expenses required for the domestic sales of identical / similar goods, domestic transportation costs, and paid taxes & customs duties etc.)


(2)Documents need to prepare

  • The evidence to prove the domestic selling price
  • The materials to prove the domestic expenses (Invoice receipt from logistic companies, invoice receipt to confirm the paid taxes & customs duties)


[4] Use of the production cost method


When the manufacturing cost of the imported goods can be identified, the customs value can be determined by follows.

Customs value = Production cost of the import goods + (general profits and expenses of export sales of identical / similar goods and the transportation costs until arrival at the port in Japan) 


(2)Documents need to prepare

  • The evidence to prove the manufacturing cost, such as accounting ledger of the producer
  • The materials to prove the profit and expenses added to the production costs, such as  invoices


[5] Other methods


If the methods mentioned previously cannot be used, Other methods will be applied.

Practically, in many cases, we apply this other methods.


As an example, we’d like to introduce one of the other methods which is applying to Amazon FBA’s case, that overseas seller ship and import their goods to Japan.

Customs value = Selling prices in average※5 - Deductible costs (e.g. FBA fee, Referral fees)※6 

※5:Average of the selling prices is basically for the goods soled in past 30days on Amazon’s website.

※6:The deductible costs incurred after the arrival of the imported goods in Japan can be considered as deductible costs.


(2)Documents need to prepare

  • The materials to prove the selling prices in average, and deductible costs you use for the calculation.

This revision mandates foreign entities to comply with new regulations, which include the compulsory utilization of an Attorney for Customs Procedures (ACP). Under this new framework, it is expressly forbidden for foreign sellers to appoint another Japanese service provider in the role of Importer of Record (IOR).

How does the Japanese New Invoice System affect?  – Advantage of using ACP –

Recently, many companies register JCT (Japanese Consumption Tax) because the new invoice system for JCT will start in October 2023. The concept of the new invoice system is very similar to the EU’s VAT invoice system.

Your Japanese customer can’t claim input 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 the Invoice system is introduced (before Oct 2023):

  • A company that paid consideration of goods or services (=Company-B) is able to deduct Input JCT of the consideration regardless of whether the vendor (issuer of invoice, =Company-A) is a JCT-taxable or Non JCT-taxable company.
  • There is no way to confirm whether the vendor (=Company-A) is JCT-taxable or Non JCT-taxable company.

After the Invoice system is introduced (after Oct 2023):

  • A company that paid consideration of goods or services (=Company-B) is able to deduct Input JCT of the consideration only if the vendor (Company-A) has its invoice registration number.
  • Company-B requests Company-A to issue the qualified invoice. If Company-A cannot submit qualified invoice, Company-B will no longer want to buy from Company-A.

**If Company-A only sells to consumers (not business entities), it may not require for Company-A to issuethe qualified invoice since normally consumers would not tend to do tax return. 



Once the Comapny-A (Seller/Supplier) obtains the JCT invoice registration number, which means this company becomes a taxable entity that is obligated to file JCT tax returns on a regular basis.

For the case of a non-resident entity (Company-A), when Company-A imports and sells to customers in Japan, following 3 steps are the standard procedure.

(1) Pay import JCT to a customs office, 10% of the import customs value when Company-A imports.
(2) Obtain JCT from a customer in Japan, 10% of the sales price when Company-A sells
(3) Submit JCT tax return
   (3-1) If you paid (1) as IOR = Importer, which means you appoint ACP, then you’re required to pay only the difference amount (2) – (1)
   (3-2) If you paid (1) but you were not IOR = Importer, then you’re required to pay all the amount of (2). You can’t deduct (1).


Please be careful that only the IMPORTER can deduct the input JCT (import consumption tax) at the time of tax filing mentioned above (3). In other words, if another IOR service provider became the IMPORTER when you import, basically it would not be possible for the non-resident entity to deduct the input JCT (import consumption tax). Therefore, you have to pay all the amount of (2) to a tax office (mentioned above (3-2).

On the other hand, if you import with ACP, means that you became an IMPORTER thus you can deduct the input JCT (import consumption tax), when you do JCT tax return mentioned above (3). Therefore, you only need to pay the difference amount (2) – (1) to a tax office (mentioned above (3-1).

This is one of the significant advantages to use ACP service, not IOR service.

For this reason, we strongly recommend using ACP so that you can become IOR.
