As previously mentioned in another article ("Announcement from Japan Customs | Mandatory to Use ACP in Many Cases – Attorney for Customs Procedure"), from October 2023, overseas sellers, especially those on e-commerce platforms like Amazon, Rakuten, and Shopify, are now necessary to utilize ACP and become the Importer of Record (IOR) themselves. Therefore, schemes involving designating other Japanese corporations as the IOR are no longer feasible. Despite clear directives to this effect, we observe certain IOR businesses providing unauthorized IOR services.

The prevalence of such questionable practices necessitates this article as a cautionary note. Sellers operating in Japan must strive to understand and comply with the correct legal framework and avoid unnecessary penalty.

Problematic Practices – Violation of Customs Laws

There are instances where transactions seem to exist between overseas businesses and Japanese IORs (who are merely importers in name), with manipulated documents like invoices reflecting undervalued declared prices for customs clearance. In reality, these goods are not directly shipped to fulfillment centers like Amazon but temporarily stored in domestic warehouses. Here, they are labeled before being sent to the final fulfillment destination. This scheme aims to avoid detection by customs as e-commerce products. Such actions are illegal and not in compliance with the law, and I strongly urge an immediate cessation of these practices.

Importing through illegal schemes often leads to undervalued import declarations. Even if customs clearance is initially granted, subsequent Post Clearance Audit by customs can lead to substantial penalties. Legally, the IOR is liable for these payments, which can lead to disputes between overseas sellers and IOR businesses. Typically, the financial burden of import duties and taxes falls on the overseas sellers, making conflicts predictable.

Both the uninformed overseas businesses using these illegal schemes and the IOR operators bear responsibility.

Observing extremely low prices for products by overseas sellers on e-commerce platforms like Amazon often gives an impression of an unfair competitive environment. Legitimate overseas businesses pay appropriate taxes and add these costs to their selling prices, putting them at a disadvantage against sellers who avoid proper tax payments. This unfairness is precisely why the customs system was revised in October 2023.

For businesses with low compliance awareness, the issues likely extend beyond just declared values. Often, they might also be non-compliant with intellectual property laws and other regulations.

Concerns Over Cost Impact of Customs Valuation/Import Declarations

When overseas sellers import goods for e-commerce into Japan, whether through ACP or as the another IOR company, there is no "import transaction" with a Japanese buyer, leading to the exceptional determination method for declared import values, typically based on the domestic selling price.

There are concerns about high valuation leading to excessive duties and taxes. However, this is a determination method based on the Customs Tariff Law, which must be adhered to. The cost impact of the valuation is not as significant as often feared.

The taxes on import are mainly customs duties and consumption tax. Japan’s import tariffs are relatively low on a global scale, and many industrial products are duty-free. As for consumption tax, which is a uniform 10%, it is an indirect tax borne by the final consumer, not a cost for the overseas seller. Taxable businesses regularly file consumption tax returns to the tax office, adjusting the tax paid on imports against the tax collected from sales, neutralizing the cost impact. However, this necessitates that the overseas business itself becomes the importer, achievable only through using ACP.

With the start of the consumption tax invoice system in October 2023, many overseas businesses might have registered as qualified invoice-issuing entity. For B2C businesses, registration as a qualified invoice-issuing entity is not always necessary, but many companies seem to register without fully understanding the system. I recommend that overseas businesses seek advice from qualified professionals to navigate these changes correctly.

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 who has a right to disposition 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.

Please Be Aware

In cases where foreign corporations (non-residents) without an office in Japan import goods, failure to properly prepare an Importer of Record (IOR) through an Attorney for Customs Procedures (ACP) or similar means can result in goods being held at customs, leading to significant delays and costs. To avoid such risks, please make thorough preparations.

If an ACP is needed, it is crucial to utilize the services of an experienced ACP well-versed in customs-related laws and regulations. The import and export operations of non-residents/foreign corporations using an ACP are treated as unique cases. Many customs brokers are not familiar with these procedures, leading to incidents where goods are detained for extended periods due to unsuccessful explanations to customs. (Customs will not permit the import if the explanations provided by the importer or customs broker are unsatisfactory, resulting in the goods being detained until customs is convinced.)

We highly recommend utilizing our services as professional experts in customs, knowledgeable about customs-related laws and regulations. With a proven track record of resolving numerous issues through direct consultations with customs officers and customs brokers, our clients supported as an ACP now exceed 100 companies.
