Thai manufacturers shipping to Japan, particularly in auto parts, electronics components, food and agricultural products, and rubber and plastics goods, are routinely routed through a Japan-based trading company or intermediary that ends up named as the importer of record on the customs declaration. That arrangement is convenient administratively, but it removes the Thai manufacturer from the customs valuation chain, weakens its control over how preferential origin claims are filed, and makes it dependent on a third party for information about its own shipments. A different structure exists for manufacturers that already hold genuine commercial control over the goods they export: Attorney for Customs Procedures (税関事務管理人, ACP), a status that allows a non-resident company's own name to appear on the Japan import declaration (輸入申告) without establishing a Japan entity.
Thailand's Export Profile to Japan and the Importer-of-Record Problem#
Thailand is one of Japan's most consistent Southeast Asian trading partners. Auto parts and automotive components, electronics and electronic components, processed food and agricultural products, and rubber and plastics goods make up a large share of Thailand-to-Japan trade flow, reflecting Thailand's position as a manufacturing and assembly base for both regional and Japanese-affiliated supply chains.
For manufacturers in these categories, the identity of the importer of record on the Japan side carries legal weight. Japan Customs' standard for who may be named as importer turns on disposition rights (処分権限), meaning the party named must have substantive commercial authority over the goods, such as the right to decide their use, resale, or disposal, not merely a role as a documentation placeholder. A Thai manufacturer that sells directly to a Japan buyer, retains title through the point of sale, and bears the commercial risk of the transaction meets that standard on its own. When such a manufacturer is nonetheless routed through an intermediary importer, it typically has weaker visibility into how the customs valuation, the origin claim, and the tariff treatment on its own goods were actually filed.
Japan's Trade Agreement Network with Thailand: JTEPA and RCEP#
Japan and Thailand have a bilateral economic partnership agreement (the Japan-Thailand Economic Partnership Agreement, 日タイ経済連携協定, JTEPA), and both countries are also parties to the wider Regional Comprehensive Economic Partnership (RCEP). This means that qualifying goods manufactured in Thailand and exported to Japan may be eligible for preferential duty treatment under either framework, depending on which agreement's rules of origin the specific product line satisfies and which set of cumulation and processing rules is more favorable for that product.
Aplash does not state specific tariff percentages in this article because the applicable preferential rate depends on the HS classification of the goods, the origin criteria the goods meet, and the tariff schedule in force under JTEPA or RCEP at the time of import. What is consistent across both agreements is the documentation burden: claiming preferential treatment requires a certificate of origin or an origin declaration that satisfies the invoked agreement's rules, and the party best positioned to substantiate that documentation is the party that can speak directly to the underlying transaction, meaning the actual manufacturer, not an intermediary standing between the manufacturer and Japan Customs. Exact duty rate and origin-criteria determinations should be confirmed through Aplash or through an advance ruling with Japan Customs before being relied upon commercially.
ACP: Staying the Named Importer Without a Japan Entity#
The Customs Act (関税法) contains a mechanism that lets a non-resident company, meaning a company with no address, residence, or office in Japan, remain the legal importer named on the Japan import declaration while a Japan-resident agent handles the procedural interface with Japan Customs on its behalf. This appointment is Attorney for Customs Procedures (税関事務管理人, ACP). No title to the goods passes to the ACP agent at any point, and no Japan entity is created. The Thai manufacturer stays the importer of record. Aplash, as the Japan-resident ACP agent, files the appointment notification with the relevant Customs office, serves as the statutory point of contact for Customs inquiries, and manages post-clearance documentation obligations.
This bears directly on the JTEPA and RCEP point above. When the Thai manufacturer itself is the named importer, its own transaction price is the customs valuation basis and its own origin documentation is what gets filed, rather than an intermediary's resale terms and an intermediary's handling of the origin claim. It also matters for ordinary commercial reasons: brand control, pricing discipline, and the customer relationship in Japan stay with the manufacturer rather than being intermediated by a third party appearing as the legal importer.
IOR
ACP is not the only structure available to a non-resident manufacturer that wants to reach the Japan market. Aplash's separate Importer of Record (IOR) service is for manufacturers that want to step out of the import chain: Aplash itself takes title through a buy-and-sell arrangement and becomes the named importer.
ACP
IOR and ACP are distinct legal frameworks with different parties named on the declaration and different liability and tax-recovery paths; they are never interchangeable and are never presented as alternatives to each other. This article addresses the manufacturer that wants its own name on the declaration, which is the ACP case.
ACP vs Using a Customs Broker Alone#
A Thai manufacturer that already works with a licensed customs broker (通関業者) in Japan may reasonably ask why ACP is a separate consideration. The two roles are not substitutes. A customs broker prepares and files the import declaration on behalf of whoever is named as importer, but a customs broker does not, and cannot, resolve the underlying problem that a non-resident company has no standing before Japan Customs to be named as importer in the first place. The Customs Act's non-resident provision is what allows a non-resident to be named importer at all, by requiring that a Japan-resident agent, the ACP, stand behind that appointment as the statutory contact point.
In practice, most Thai manufacturers that use ACP will still want their import declarations physically prepared and filed by a licensed customs specialist. Aplash coordinates that filing as a separate element of a combined engagement; the ACP appointment itself is a legal status rather than a filing service. A manufacturer that already has its own broker relationship in Japan may only need the statutory ACP appointment layered on top; a manufacturer without an existing broker relationship typically needs both the appointment and the filing coordination. Exact scope and cost depend on shipment volume, product classification, and whether the manufacturer already has a broker in place, and should be confirmed with Aplash directly before any general description is relied on.
Practical Registration and Setup Steps#
At a high level, bringing a Thai manufacturer onto an ACP structure follows a consistent sequence:
(a) Corporate verification: Aplash reviews the Thai entity's corporate registration documents and confirms the entity's authority to appoint a Japan-resident agent, typically through a board resolution or power of attorney.
(b) Non-resident status confirmation: Aplash confirms the manufacturer has no Japan address, residence, or office, since ACP is available only to non-resident principals; if the manufacturer already has a Japan-registered entity, ACP does not apply and a different structure is appropriate.
(c) ACP appointment filing: Aplash files the appointment notification with the relevant Japan Customs office, naming Aplash as the statutory 税関事務管理人 for the manufacturer's shipments through that office. This filing cannot be made retroactively; it must precede any import declaration under the arrangement.
(d) Customs clearance coordination: if the manufacturer does not already have its own Japan customs broker relationship, Aplash coordinates preparation and filing of the actual import declarations through a licensed customs specialist, as a separate service layer from the ACP appointment itself.
(e) Tax agent and invoice registration, if consumption tax recovery is needed (see below).
(f) Ongoing compliance: Aplash retains required records, serves as the point of contact for any Customs inquiry, and manages port-specific filings if the manufacturer ships through more than one Japan Customs office, since each additional port requires its own appointment filing.
JCT Recovery Under the ACP Route#
Recovering Japan consumption tax (JCT) paid at import follows the same framework applied across Aplash's ACP engagements, described here at the framework level without a fixed price point. The non-resident Thai manufacturer, having appointed Aplash as ACP, separately appoints a Tax Agent (納税管理人) to handle its Japan tax filings, and registers as a Qualified Invoice Issuer (適格請求書発行事業者) if it intends to issue qualified invoices for downstream Japan sales. Import JCT paid at clearance becomes creditable against output JCT once this full structure, the ACP appointment, the Tax Agent appointment, and the Qualified Invoice Issuer registration, is in place. The consumption tax return itself is filed by a Licensed Tax Accountant (税理士); the underlying agent appointments and registrations do not require a tax accountant's license to establish. Without all three elements in place, import JCT becomes an unrecoverable cost to the manufacturer.
