Most foreign companies evaluating an Importer of Record (IOR) provider in Japan start with price and turnaround time. Those matter, but they are not the questions that determine whether the arrangement actually protects you. The Customs Act (関税法) places specific legal weight on who is named on the import declaration (輸入申告) and who holds disposition authority (処分権限) over the goods at the moment of clearance. If your provider cannot answer precisely how that works in its own operation, the label on their pitch deck ("IOR") may not match the legal substance of what they are doing. This is a due-diligence checklist for the buyer's side of that conversation, not a comparison of named vendors.
Why This Distinction Is Worth Slowing Down For
An IOR provider that genuinely takes title to your goods, files the import declaration in its own name, and bears the resulting customs liability is a fundamentally different counterparty than one that files paperwork on your behalf while you remain the legal importer. Both structures are legitimate. The problem arises when a provider markets the second structure using the language of the first, because the liability allocation, the tax mechanics, and your own regulatory exposure are different in each case.
Question 1: Who Is Actually Named on the Import Declaration?
Ask the provider, in writing, whose name appears on the import declaration filed with Japan Customs, and ask them to confirm this in the contract, not just in a sales call. A provider that genuinely functions as IOR is the named importer: it holds legal title to or a legal right over the goods at the time of declaration, and it is the party Customs will pursue for undervaluation, misclassification, or duty shortfall.
If the answer is vague ("we handle the customs side" or "our partner clears it"), press further. A provider that files under your company's name, or under a broker's name with you remaining the substantive importer, is not operating an IOR structure. It may be running an Attorney for Customs Procedures (税関事務管理人) arrangement under Customs Act Article 95, where a Japan-resident agent handles procedures on behalf of a non-resident importer who remains named. That is a valid and separate service. It is not the same liability profile as IOR, and a provider that blurs the two in its marketing is a signal worth taking seriously, not a technicality.
Question 2: Does the Provider Genuinely Take Title, or Is This ACP Dressed As IOR?
Name-lending (名義貸し), appearing on a customs declaration without genuine commercial substance behind it, is not a gray area under the Customs Act. A provider that lists itself as importer without an actual purchase agreement, without title transfer, and without a subsequent re-sale to your organization is exposing itself, and by extension you, to a false-declaration risk.
Ask for the mechanics in plain terms: does the provider purchase the goods from your overseas seller under its own name, take delivery risk, and then re-sell to your Japan-side buyer under a separate invoice? A provider that cannot describe a purchase-and-resale chain, an entity that took title before the goods cleared and title that changed hands again afterward, is likely running a procedural or agency arrangement while using IOR terminology. Ask specifically: "If these goods are damaged or lost between purchase and resale, who bears that loss?" A genuine IOR provider answers that question immediately, because the answer is "we do." A provider running a disguised agency arrangement will hedge, because contractually, they may not.
This distinction is not cosmetic. It determines whether the provider's balance sheet stands behind your import, or whether you remain the real party in interest regardless of what the marketing materials say.
Question 3: Consumption Tax Input Credit and Qualified Invoice Issuance
A genuine IOR provider pays import consumption tax (輸入消費税) under the Consumption Tax Act (消費税法) at the point of clearance and, on re-sale to you, issues a Qualified Invoice (適格請求書) under Japan's Qualified Invoice Issuer system. That invoice is what allows your Japan-side buyer to claim input tax credit on the transaction.
Ask the provider three things: (a) is the provider registered as a Qualified Invoice Issuer, and can it show its registration number; (b) does the re-sale invoice separately itemize the goods cost, duties, and consumption tax pass-through, or is it bundled in a way that obscures the tax treatment; (c) who bears the risk if a Qualified Invoice is issued incorrectly and your buyer's input credit claim is later challenged. A provider that cannot answer the registration question directly, or that treats invoice formatting as an afterthought, is creating a downstream tax problem for your Japan buyer that will surface long after the shipment has cleared.
Question 4: How Should Deposit, Bond, and Working-Capital Exposure Be Structured?
IOR arrangements frequently require security deposits or bonds, particularly for temporary admission, high-value cargo, or goods subject to closer customs scrutiny. Before signing, get clarity on three points: (a) is the deposit or bond amount passed through to you at the actual cost the provider incurs, or is there an undisclosed markup baked into the figure; (b) is any arrangement or handling fee for managing the deposit itemized as a separate, disclosed line, rather than folded silently into the deposit amount itself; (c) what is the provider's documented process and timeline for returning the deposit once the transaction closes or the goods are re-exported.
A provider unwilling to separate the pass-through cost from its own fee, or unable to state a concrete return timeline in the contract, is asking you to carry undefined working-capital exposure. This is covered in more depth in Aplash's dedicated guide on deposit and bond cost structures; the point for vendor selection is simply that the contract, not a verbal assurance, must state these terms.
Question 5: How Is Post-Clearance Audit Exposure Allocated?
Japan Customs conducts post-clearance audits (事後調査) that can occur well after a shipment has cleared and the transaction has closed commercially. This is one of the most frequently underspecified areas in IOR contracts, because the exposure is deferred and easy to paper over at signing.
Ask directly: if Customs reopens the declared value, classification, or origin determination on a shipment months after clearance, who is contractually obligated to respond to the audit, who bears any resulting duty reassessment or penalty, and does the provider's obligation to cooperate survive termination of the underlying service agreement. A provider whose contract is silent on post-clearance audit allocation is leaving you to discover, potentially years later, that the entity named on the original declaration either cannot be reached or disclaims responsibility. Because the named importer is the party Customs will pursue, this allocation should track the same logic as Question 1: the entity named on the declaration bears the audit exposure, and the contract should say so in explicit terms.
Red Flags Checklist
Treat any of the following as a reason to slow down before signing:
(a) Liability language that describes the provider's role using words like "facilitate," "coordinate," or "process on your behalf" without ever stating who is legally named on the import declaration.
(b) No written scope statement identifying, in the contract itself, which entity appears as importer on the customs filing. A provider that will not put this in writing is not a provider you can rely on if Customs later asks the same question.
(c) An inability or unwillingness to walk through the resale invoice mechanics: the purchase price from your seller, the resale price to your buyer, and how duties and consumption tax are itemized between the two.
(d) Reluctance to explain, when asked directly, whether the arrangement is IOR (provider is the importer) or an Attorney for Customs Procedures structure (you remain the importer). A provider that treats these as interchangeable, or presents them as "options" rather than structurally distinct services, either does not understand the distinction or is obscuring it.
(e) No contractual language addressing post-clearance audit responsibility, deposit/bond return timelines, or what happens if the provider ceases operations while a shipment is still within Japan Customs' audit window.
What a Legitimate Provider's Contract Should Explicitly State
A contract that reflects genuine IOR substance should state, at minimum: (a) the provider's legal name as it will appear on the import declaration; (b) confirmation that the provider takes title to the goods under a purchase agreement prior to declaration, and re-sells under a separate agreement following clearance; (c) the provider's Qualified Invoice Issuer registration and its obligation to issue a compliant qualified invoice on resale; (d) itemized treatment of any deposit or bond, distinguishing the pass-through amount from any arrangement fee, with a stated return timeline; (e) an explicit allocation of responsibility and cost for post-clearance audit, valuation challenges, and any resulting duty reassessment, including whether this obligation survives contract termination; (f) a liability cap and carve-outs consistent with the risk actually being transferred, not a boilerplate limitation that contradicts the "we are your importer" framing elsewhere in the same document.
If a provider's contract cannot produce these terms in writing, on request, before signature, that is itself the answer to the due-diligence question.
