Korean manufacturers exporting to Japan through Japanese trading companies or distributors as nominal importers are operating under a customs structure that the October 2023 Japan Customs reform has made non-compliant in the majority of standard configurations. The compliance exposure is direct: a customs declaration naming the wrong party as importer carries penalties under the Customs Act (関税法), and the import consumption tax (消費税) paid at clearance is permanently irrecoverable if the named importer does not match the party that holds genuine commercial control over the goods. This article explains how the Attorney for Customs Procedures (税関事務管理人) structure lets a Korean manufacturer stay named as importer of record on Japan customs declarations without a Japan entity, what the Korea-specific setup process involves, and how the structure interacts with preferential tariffs under the Japan-Korea Economic Partnership Agreement and RCEP.
Why Korean Manufacturers Are Affected by the October 2023 Reform
The October 2023 Japan Customs clarification established a substantive standard for who qualifies as importer of record (輸入者) on a Japan import declaration (輸入申告): the named importer must hold genuine disposition rights (処分権限) over the goods. Disposition rights means the legal authority to determine what happens to goods after customs clearance, including the right to set the sale price to end buyers, direct distribution channels, and retain or reallocate stock.
Before 2023, the default structure in much of the Korea-Japan trade corridor involved the Korean manufacturer shipping goods under arrangements where a Japanese trading company (商社), distributor, or freight forwarder handled the import declaration in its own name. The Japanese party was named as importer of record as an operational convenience. In the majority of these arrangements, the Korean manufacturer was setting the commercial terms, retaining title during transit, or directing how goods were handled after clearance. Under the post-2023 standard, that party holds disposition rights and should be the named importer. The Japanese intermediary, acting only as a logistics or distribution conduit, does not.
The consequence is that Korean manufacturers relying on Japanese intermediaries as nominal importers under arrangements where the manufacturer retains commercial control are filing declarations that do not accurately identify the importer. The Customs Act (関税法) treats this as a false declaration. The business also loses the ability to reclaim import consumption tax paid at clearance, because only the party named on the declaration can credit that tax against output consumption tax on Japan sales.
Korea is Japan's third-largest import source. The affected product categories span the full breadth of Korean export strength: semiconductors and displays, steel and metals, petrochemicals, automotive parts, consumer electronics, beauty and cosmetics (화장품), food products including kimchi (김치), packaged snacks, and seafood. Any Korean manufacturer in these categories whose Japan import declarations currently name a Japanese third party as importer should assess whether that arrangement reflects genuine disposition rights or is a nominal structure that no longer meets the post-2023 standard.
The Two Compliant Structures
A Korean manufacturer exporting to Japan has two structurally distinct compliant options. These two structures are not interchangeable, and they are not alternatives to select based on preference. The applicable structure depends on who genuinely holds disposition rights over the goods.
Structure A: Japanese buyer as importer, where a genuine buy-sell relationship exists. If the Korean manufacturer sells goods outright to a Japanese company that takes full title, bears commercial risk, and has independent authority to resell, reprice, or redistribute those goods without direction from the Korean seller, that Japanese company holds genuine disposition rights and qualifies as importer of record under the post-2023 standard. This is a compliant arrangement, provided the distribution agreement as actually structured reflects a real buy-sell relationship rather than an agency, consignment, or logistics arrangement. Korean manufacturers should review their Japan distribution agreements for provisions that undercut the Japanese party's genuine independence: price protection clauses, guaranteed buyback rights, manufacturer-directed resale pricing, or stock-return mechanisms can all bring a nominally buy-sell arrangement below the disposition-rights threshold.
Structure B: Korean manufacturer as importer of record via Attorney for Customs Procedures. Under Article 95 of the Customs Act (関税法), a non-resident entity with no Japan address, office, or residence can be named as importer of record on Japan customs declarations by appointing a Japan-resident agent as its Attorney for Customs Procedures (税関事務管理人). The attorney acts as the statutory contact point for Japan Customs, accepts service of all customs notices and inquiries, and coordinates the import declaration process. The Korean manufacturer is named on the import declaration as the legal importer and retains full title to and commercial control over the goods throughout. The attorney takes no title; no buy-sell transaction with the attorney occurs.
For Korean manufacturers whose Japan commercial arrangements do not involve a genuine buy-sell distributor, or who have commercial reasons to maintain their own importer identity in the Japan market, Structure B is the operative path. The discussion in this article focuses on Structure B.
Three Required Registrations
Establishing the Attorney for Customs Procedures structure requires three registrations with two separate Japanese government authorities. All three must be completed before the first import declaration is filed under the Korean manufacturer's name.
(a) ACP Notification with Japan Customs. The Japan-resident attorney files the ACP notification form (税関事務管理人届出書) with the relevant Japan Customs office. This filing records the appointment formally, identifies the non-resident Korean manufacturer as the importer, and specifies the ports of entry where declarations will be filed. A single notification does not extend across ports: each customs office where the manufacturer intends to clear goods requires its own filing. Aplash handles this filing as part of the ACP engagement.
(b) Tax Representative Appointment with the National Tax Agency. The Korean manufacturer must appoint a Tax Representative (納税管理人) with Japan's National Tax Agency (国税庁) under applicable tax administration law. This registration establishes the Japan-resident point of contact for consumption tax matters arising from the non-resident's import activity. The Tax Representative appointment is legally distinct from the ACP appointment and involves a separate filing with a separate government authority, though in practice Aplash typically serves in both roles for the same client.
(c) Qualified Invoice System Registration. The Korean manufacturer must register as a Qualified Invoice Issuer (適格請求書発行事業者) under Japan's Qualified Invoice System (インボイス制度), administered by the National Tax Agency. This registration is the prerequisite for claiming import consumption tax paid at clearance as an input tax credit and for issuing tax-compliant invoices to Japanese buyers. The National Tax Agency's processing window for registration runs approximately four to six weeks. Import consumption tax paid before registration is complete cannot be credited retroactively. QIS registration is the critical-path item in the setup timeline and must be initiated at engagement start, not after the ACP notification has been filed.
The ACP notification and Tax Representative appointment can be initiated in parallel. The practical setup timeline for Korean manufacturers is typically four to six weeks from engagement start to all three registrations being in place.
Korea-Specific Document Authentication
Korean corporate documents require formal authentication before they can be relied upon in Japanese government filings. The process is well-established and follows a predictable path.
Korea acceded to the Hague Convention Abolishing the Requirement of Legalisation for Foreign Public Documents in 2019. This means Korean public documents can be apostilled directly by Korean authorities, removing the need for consular authentication chains. The relevant authenticating authority is the Ministry of Foreign Affairs of Korea (외교부), which issues apostilles on documents within its scope.
In practice, the documents required for Japan Customs ACP notification and National Tax Agency registration include: the Korean manufacturer's corporate registration certificate (법인등기부등본), the business registration certificate (사업자등록증), and authorization documents confirming the signatory's authority to appoint an ACP. These documents must carry a Korean apostille and, where the documents are in Korean only, certified Japanese or English translations.
The apostille path in Korea is operationally straightforward. Korea's apostille infrastructure handles volume efficiently, and the turnaround from document preparation to authenticated document is generally faster than in jurisdictions without Hague Convention membership. Aplash coordinates the document checklist and translation requirements at onboarding.
EPA and RCEP Preferential Tariffs: How the IOR Structure Affects Origin Claims
Korea-Japan trade benefits from two preferential tariff frameworks: the Japan-Korea Economic Partnership Agreement (日韓EPA) and the Regional Comprehensive Economic Partnership (RCEP, 地域的な包括的経済連携協定). The interaction between these frameworks and the importer-of-record structure is a point that Korean manufacturers frequently overlook.
Under both frameworks, the importer named on the Japan customs declaration is the party that formally invokes the preferential tariff rate and must hold the qualifying origin documentation at the time of declaration.
Under RCEP, origin is demonstrated by a Certificate of Origin (원산지증명서 / 原産地証明書) issued in Korea under the RCEP rules of origin. Under the Japan-Korea EPA, the relevant document is Form KJ, which serves as the origin declaration under the bilateral agreement.
The structure matters in two ways. First, if the importer of record on the Japan customs declaration is the Japanese trading company or distributor rather than the Korean manufacturer, the origin documentation must be held by and produced by that Japanese importer at declaration. The Korean manufacturer cannot invoke preferential rates on behalf of a Japanese importer who happens to be clearing the goods. Second, where the Korean manufacturer is the importer of record under Structure B, the manufacturer holds the origin documentation directly and can invoke the preferential rate on its own declaration, provided all eligibility requirements are met.
The practical implication: Korean manufacturers selling goods to Japan that qualify for preferential tariff treatment under RCEP or the Japan-Korea EPA, but whose current import structure names a Japanese intermediary as nominal importer, may also be failing to claim preferential rates correctly. The ACP structure, by placing the Korean manufacturer as named importer, creates the direct chain from the origin documentation to the import declaration that both frameworks require.
Whether any specific goods qualify for preferential treatment under RCEP or the Japan-Korea EPA depends on the applicable rules of origin and the tariff classification of the goods. These determinations are fact-specific and outside the scope of this article.
Consumption Tax Recovery: The Financial Case for the ACP Structure
The financial argument for the ACP structure in high-volume Korea-Japan trade flows is the consumption tax (消費税) recovery. Japan's consumption tax rate is 10 percent on standard-rated goods. Import consumption tax is assessed on the customs value of the goods at clearance and is paid by the named importer.
Under a nominal importer arrangement where the Japanese trading company is named on the declaration, the import consumption tax is paid by the Japanese importer. The Korean manufacturer, not being the named importer, has no mechanism to claim that tax back. The consumption tax paid at clearance becomes a permanent cost embedded in the supply chain.
Under the ACP structure, the Korean manufacturer is the named importer and pays the import consumption tax directly. Through the Tax Representative appointment and Qualified Invoice System registration described above, the manufacturer can claim that import consumption tax as an input tax credit against output consumption tax on its Japan sales. For manufacturers selling into Japan at scale, this recovery is material. On a consignment of goods with a customs value of 100 million yen, the import consumption tax at the standard rate is 10 million yen. Without the ACP structure, that sum is a cost. With the ACP structure in place and the QIS registration completed, it is creditable.
The recovery path requires all three registrations to be functional before the import declaration is filed. The JCT recovery setup, covering the Tax Representative appointment and QIS registration coordination, is a one-time cost. The input tax credit mechanism then operates on a rolling basis across all subsequent shipments under the manufacturer's importer registration.
Aplash's Role
Aplash acts as Attorney for Customs Procedures (税関事務管理人) for the Korean manufacturer under Article 95 of the Customs Act (関税法). Aplash files the ACP notification with Japan Customs, serves as the statutory contact point for all Japan Customs inquiries directed at the non-resident importer, and coordinates the import declaration process with a licensed customs specialist (通関士). Aplash also serves as Tax Representative (納税管理人) and files the required notifications with the National Tax Agency, coordinating QIS registration in the same setup process.
The ACP engagement does not involve Aplash taking title to goods or acting as buyer or seller in the Korea-Japan transaction. The Korean manufacturer remains the importer of record, the owner of the goods, and the commercial counterparty to its Japan customers throughout.
For Korean manufacturers considering the IOR structure instead, in which a Japan-resident entity purchases the goods and clears them in its own name, that is a structurally distinct service with different implications for title, tax, and commercial relationships. It is addressed separately.
