UK manufacturers exporting to Japan operate under a different trade agreement than their EU counterparts, and the distinction is not a formality. The UK-Japan Comprehensive Economic Partnership Agreement (CEPA) came into force on 1 January 2021 as a standalone bilateral agreement, separate from the EU-Japan Economic Partnership Agreement that continues to apply to EU member states. A UK manufacturer with no Japan-registered office or subsidiary faces the same structural question every non-resident exporter faces: who is the legal importer named on the Japan import declaration (輸入申告), and how is a preferential tariff claim made on that declaration? This post covers the Attorney for Customs Procedures (税関事務管理人) structure for UK manufacturers, how UK-Japan CEPA origin procedures differ from relying on the EU-Japan framework, and how consumption tax (消費税, JCT) recovery works once CEPA is in place.
Post-Brexit: Why the EU-Japan EPA No Longer Applies to UK Goods
Before the UK left the EU customs and trade framework, UK-origin goods exported to Japan could qualify for preferential tariff treatment under the EU-Japan Economic Partnership Agreement, because the UK was an EU member state at the time that agreement was negotiated. That route no longer exists. Since the UK's departure from the EU, UK exporters cannot claim EU-Japan EPA preferential rates on any shipment, regardless of similarity to a previously qualifying EU-origin product. UK-Japan trade preference now runs exclusively through the UK-Japan CEPA, negotiated bilaterally and structured with its own rules of origin, its own origin declaration process, and its own product-specific origin criteria.
The UK-Japan CEPA is substantially modeled on the EU-Japan EPA framework, which means the mechanics will look familiar to a UK manufacturer or trade compliance team that has exported into Japan before. It is not, however, the same agreement, and preference cannot be claimed by reference to the EU-Japan EPA schedule or by treating the two agreements as interchangeable. Each shipment's eligibility, applicable origin rule, and any preferential rate must be assessed against the UK-Japan CEPA specifically, per the good's own HS classification.
The Structural Problem: No Japan Entity, No Direct Filing
A UK manufacturer without a Japan-registered office, residence, or address cannot file a Japan import declaration in its own name and cannot itself claim CEPA preference on that declaration, because the declaration requires a party capable of being recognized as the importer under Japan's customs framework. Two distinct structures resolve this. They are legally separate frameworks, they are never interchangeable, and a UK manufacturer should not treat them as two flavors of the same service.
IOR (Aplash as Importer of Record). Under the Importer of Record structure, Aplash purchases the goods from the UK manufacturer and clears them through Japan Customs in Aplash's own name. Aplash is the named importer on the import declaration and, because Aplash is the importer of record, Aplash is the party that would claim CEPA preference on a qualifying shipment. The tariff benefit flows through Aplash's cost structure and is reflected in the price at which the goods are resold onward to the Japan buyer, rather than appearing directly on the UK manufacturer's own books. IOR suits a UK manufacturer that wants no Japan customs identity, ships at low frequency, or sells under a distribution arrangement where the Japan-side buyer or distributor is expected to carry import responsibility.
ACP (UK Manufacturer as Importer via Attorney for Customs Procedures). Under the Attorney for Customs Procedures structure, the UK manufacturer remains the legal importer named on the Japan import declaration. This is the direct consequence of the Customs Act (関税法) provision governing resident-agent appointment for non-resident importers, reinforced by the October 2023 reform requiring the party with actual disposal authority (処分権限) over the goods, meaning the true owner, to be the named importer rather than a nominal stand-in. The UK manufacturer appoints Aplash as its Japan-resident agent, the 税関事務管理人, to handle customs procedures on its behalf. Aplash does not take title to the goods under this structure and does not become the importer; that is the structural role IOR fills instead. Because the UK manufacturer is the named importer, the manufacturer, not Aplash, claims UK-Japan CEPA preference directly on its own import declaration. Consumption tax recovery is also available to the manufacturer under this structure once the correct registration chain is in place, covered below. ACP is available only when the UK manufacturer is a non-resident of Japan, meaning no Japan address, residence, or office. A manufacturer with an incorporated Japan entity is its own importer and engages a licensed customs broker (通関業者) directly; in that case neither ACP nor IOR from Aplash applies.
The choice between these two structures depends on the manufacturer's distribution arrangement in Japan, its appetite for holding a Japan tax and customs identity, and whether it wants direct ownership of the CEPA duty savings and JCT recovery position, or wants the entire import process handled off its own compliance register.
UK-Japan CEPA Origin Procedure
A UK manufacturer claiming CEPA preference as the named importer under ACP must support the claim with an origin declaration prepared under the UK-Japan CEPA's own rules, not the EU-Japan EPA's rules, even where the underlying mechanics resemble each other. In general terms, this means:
(a) The exporter (the UK manufacturer or its authorized representative) prepares an origin declaration on the commercial invoice or another commercial document, in the form and wording prescribed under the UK-Japan CEPA, rather than relying on any EU-issued origin instrument.
(b) The origin declaration must exist before the goods ship. It cannot be produced retroactively after Japan Customs clearance has already occurred.
(c) The goods must satisfy the UK-Japan CEPA's own product-specific rules of origin for the relevant tariff heading. Origin is not automatic simply because the goods were manufactured in the UK; the applicable origin criterion, and whether the good qualifies for a preferential rate at all, depends on the specific HS classification and must be confirmed on a per-product basis.
The UK-Japan CEPA's tariff schedule and rules of origin are structured by HS heading, and the applicable rate and origin test for any given product must be confirmed against the agreement text and the good's own classification before the first shipment, not assumed from a general description of the product category. This guide does not assert a specific origin threshold, preferential rate, or tariff schedule figure for that reason.
ACP and CEPA Preference Are Compatible, Not Coupled
ACP status and a CEPA preference claim answer two separate questions and do not depend on each other. ACP under the Customs Act's resident-agent provision answers the procedural question: who is Japan Customs' point of contact for a non-resident importer, and how does that importer lawfully appear on the declaration without a Japan presence. CEPA preference answers the tariff question: at what rate are the goods assessed, based on origin and classification. A UK manufacturer can hold ACP status, file under its own name as importer, and separately claim CEPA preference on each qualifying shipment. Neither mechanism constrains the other, and a UK manufacturer that already holds ACP status for non-preferential shipments does not need a different structure to begin claiming CEPA preference; it needs the correct origin documentation.
JCT Recovery for UK Manufacturers Under ACP
Under ACP, the UK manufacturer is the importer of record and pays consumption tax at the Japan border on import clearance. That tax is not a permanent cost if the correct registration chain is completed:
(a) ACP appointment with Japan Customs. Aplash files the 税関事務管理人届出書 on the manufacturer's behalf, establishing the manufacturer as the named importer under the Customs Act.
(b) Appointment of a consumption tax payment administrator (消費税の納税管理人) with the National Tax Agency. The manufacturer appoints a Japan-resident party, which Aplash can serve as directly, giving the manufacturer a tax-side presence in Japan capable of filing consumption tax returns.
(c) Registration as a Qualified Invoice Issuer (適格請求書発行事業者) under Japan's Qualified Invoice System, if the manufacturer conducts B2B sales in Japan. This registration is what makes the import consumption tax paid at the border creditable against output tax on the manufacturer's Japan sales.
Without all three registrations, import consumption tax remains an unrecoverable cost sitting outside the manufacturer's Japan tax position. With all three in place, it is offset against output tax through the manufacturer's own JCT filings, prepared by a licensed tax accountant (税理士) for the substantive tax computation and return filing.
Common Mistakes UK Manufacturers Make
Assuming EU-Japan EPA eligibility carries over. It does not. Any UK-origin shipment claiming preference into Japan must be assessed under the UK-Japan CEPA's own rules of origin, independently of whether the same product previously qualified under the EU-Japan EPA before Brexit.
Treating the UK-Japan CEPA and EU-Japan EPA as one framework because the structures look similar. The similarity in drafting does not make the agreements interchangeable. Origin declarations and the underlying legal basis for the claim must all reference the UK-Japan CEPA specifically.
Filing before the ACP appointment is on record. The 税関事務管理人届出書 cannot be filed retroactively. Any shipment cleared before the appointment is registered with Japan Customs is declared under a different importer identity.
Skipping one of the three JCT registration steps. Partial registration, for example holding ACP status without the consumption tax payment administrator appointment, leaves import JCT stranded as a permanent cost.
Assuming a specific duty rate or origin threshold applies without checking the product's HS classification. The UK-Japan CEPA's origin rules and preferential rates vary by tariff heading. Confirm the applicable rule for the specific product before the first shipment.
Timeline: What to Allow
ACP registration with Japan Customs typically runs several weeks from the time the completed 税関事務管理人届出書 is filed. UK-side origin documentation preparation, including confirming the applicable UK-Japan CEPA rule of origin for the product's HS classification, should proceed in parallel rather than after the ACP filing. A UK manufacturer new to CEPA preference claims, or new to Japan ACP structures generally, should build in time for HS classification confirmation before committing to a shipment date, since the origin declaration cannot be prepared correctly without first confirming which origin rule applies.
Conclusion
The UK-Japan CEPA gives UK manufacturers their own dedicated preferential tariff route into Japan, structurally independent of the EU-Japan EPA. Combined with an ACP appointment, a UK manufacturer can hold the Japan importer identity itself, claim CEPA preference directly, and recover import consumption tax, all without establishing a Japan entity.
