Most discussions of IOR and ACP focus on the customs mechanics: who is named on the import declaration, how JCT recovery works, and what happens when a shipment is held for inspection. Those are the operational questions. The strategic question, the one that matters when something goes wrong, is about legal liability. Japan has a product liability framework that imposes direct obligations on manufacturers and importers when a defective product causes personal injury or property damage. The structure used to import the goods determines the legal exposure of each party in the chain. An overseas manufacturer choosing between IOR and ACP is not only choosing a customs compliance model; it is making a decision about which party bears direct legal exposure under Japanese product liability law if a product defect causes harm.
Japan's Product Liability Framework
Japan's Product Liability Act (製造物責任法, PL Act), which came into force in 1995, establishes strict liability for manufacturers and importers of defective products. Under strict liability, a claimant does not need to prove negligence. The claimant must establish that the product had a defect, that the defect caused the damage, and that the party being sued falls within the category of liable parties. Proof of fault is not required.
The liable parties under the Product Liability Act (製造物責任法) are:
(a) The manufacturer (製造業者): the party that manufactured the product.
(b) The importer (輸入業者): the party that imported the product into Japan for sale or distribution.
(c) A party whose name or trademark appears on the product in a way that suggests to a reasonable consumer that they are the manufacturer, even if they are not the actual manufacturer.
The importer category is what creates the direct structural dependency between the IOR/ACP choice and product liability exposure in Japan. The "importer" in the PL Act context is the party who brought the goods into Japan for the purpose of supplying them in the Japanese market. This is not a technical customs-declaration question; it is a commercial-purpose question. But the customs structure creates strong evidentiary signals about who that party is.
Product Liability Under an IOR Structure
Under an IOR buy-and-sell arrangement, Aplash is the named importer on the Japan customs declaration. Aplash purchased the goods from the overseas manufacturer, cleared customs, and re-sold the goods to the Japan buyer. Aplash is a commercial actor in the supply chain in Japan: it imported the goods and it sold them into the Japanese market.
Under the Product Liability Act (製造物責任法), Aplash, as the importer who placed the goods in the Japan market, potentially falls within the importer liability category. At the same time, the overseas manufacturer remains the manufacturer and retains manufacturer liability under the PL Act regardless of the import structure used.
What this means practically:
(a) A Japan buyer or end consumer who suffers harm from a defective product has two potential PL Act defendants: the overseas manufacturer (as manufacturer) and Aplash (as importer and the party that re-sold the goods in Japan).
(b) Aplash's IOR service agreements include indemnification provisions from the overseas manufacturer. The commercial understanding between Aplash and its IOR clients is that the manufacturer indemnifies Aplash for product liability claims arising from defects in the manufacturer's goods. But indemnification is a contractual right; it does not prevent a PL Act claim from being asserted against Aplash in the first instance.
(c) Aplash's product liability exposure as IOR is a real cost component of the IOR service model. It is part of why IOR fees are structured as they are, and why Aplash conducts KYC and goods compliance review as part of onboarding.
(d) For the overseas manufacturer under IOR, the commercial consequence of a Japan product liability event runs through the indemnification framework in the IOR agreement. The manufacturer's direct legal exposure in Japan under the PL Act is as the original manufacturer, not as the importer (because Aplash is the importer in this structure).
Product Liability Under an ACP Structure
Under an ACP arrangement, the overseas manufacturer is the named importer on the Japan customs declaration. The manufacturer holds disposition rights over the goods at import and is the party who placed the goods into the Japanese market. After customs clearance, the manufacturer sells or distributes the goods to Japan buyers through its commercial arrangements.
Under this structure, the overseas manufacturer holds both manufacturer liability and importer liability under the Product Liability Act (製造物責任法). There is no intermediate importer in the chain with a potential PL Act obligation between the manufacturer and the Japan buyer. Aplash's role is limited to the statutory ACP agent function: coordinating customs procedures on behalf of the manufacturer. Aplash does not take title, does not re-sell the goods, and does not itself distribute the goods in Japan. Aplash's role under ACP does not place it within the importer liability category of the PL Act.
What this means practically:
(a) Under ACP, the overseas manufacturer concentrates both manufacturer and importer liability in its own entity. A Japan buyer or end consumer who suffers harm has one primary defendant under the PL Act: the manufacturer.
(b) This is a simpler liability structure for the manufacturer in terms of direct legal control. The manufacturer is not sharing PL Act exposure with an intermediary; it holds the complete liability position and can design its product liability insurance and recall procedures accordingly.
(c) The concentration also means the manufacturer bears the full economic cost of any Japan PL Act claim without a contractual indemnification relationship to call on. Under IOR, the manufacturer indemnifies Aplash; under ACP, there is no Aplash entity to indemnify because Aplash does not hold importer liability in the first place.
(d) Manufacturers operating under ACP with significant Japan volume, particularly in categories with personal injury risk (consumer electronics, medical equipment, food supplements, tools, vehicles), should ensure their product liability insurance covers Japan specifically as the jurisdiction where they hold importer status. General international product liability policies may not automatically extend to Japan-named-importer exposure.
The Consumer Product Safety Act and Recall Obligations
The Product Liability Act (製造物責任法) is the primary liability framework, but it is not the only relevant one. The Consumer Product Safety Act (消費生活用製品安全法) imposes specific obligations on "suppliers" (事業者), a category that includes manufacturers and importers, when a serious accident involving a product is reported. Obligations include:
(a) Reporting serious accidents to the Minister of Economy, Trade and Industry (経済産業省) within ten days of learning of the accident.
(b) Cooperating with investigations by the National Institute of Technology and Evaluation (製品評価技術基盤機構, NITE).
(c) Implementing recall or corrective action when directed by the ministry or when the supplier determines a safety issue exists.
Under IOR, the "supplier" for Consumer Product Safety Act (消費生活用製品安全法) purposes is a fact-specific determination depending on who distributed the product and in what capacity. Aplash as the importer and re-seller is a strong candidate for "supplier" obligations on the Japan side. Under ACP, the overseas manufacturer as named importer and distributor is the supplier.
The practical implication: companies operating under either structure with consumer-facing goods in Japan should understand their recall obligations before a product safety event occurs, not while managing one.
Comparing the Liability Profiles
The two structures produce meaningfully different liability distributions:
IOR:
- Overseas manufacturer: manufacturer liability under PL Act; indemnification obligation to Aplash under IOR agreement.
- Aplash: importer liability under PL Act (as re-seller in Japan); covered by manufacturer indemnification contractually, but exposed in the first instance.
- Japan buyer/end consumer: can claim against both manufacturer and Aplash.
ACP:
- Overseas manufacturer: manufacturer liability AND importer liability under PL Act; full liability concentration in the manufacturer entity.
- Aplash: no PL Act importer liability (agent role only, no title, no re-sale).
- Japan buyer/end consumer: primary claim is against the manufacturer.
Neither profile is universally superior. The question is which liability position is more manageable given the manufacturer's specific risk profile, insurance coverage, and Japan market strategy.
For manufacturers with robust global product liability insurance programs that explicitly cover Japan-as-named-importer exposure, the ACP concentration is manageable and the absence of a shared-liability intermediary simplifies claim handling. For manufacturers who prefer to limit their direct Japan legal exposure and operate through an intermediary who bears some of the importer-side risk, IOR is the structure that achieves that outcome, at the cost of the IOR fee structure and the indemnification obligation.
What to Check Before the First Shipment
For both IOR and ACP:
(a) Confirm that the manufacturer's product liability insurance covers Japan. Many global policies exclude specific jurisdictions or cap coverage in non-home markets. Japan should be verified as an included jurisdiction before goods enter the market.
(b) Ensure there is a product safety file for the goods being imported. Japan Customs does not routinely require safety documentation at import for most product categories, but having a technical file supports recall and investigation cooperation if a safety event occurs.
(c) Confirm the product's compliance with any applicable product safety standards in Japan. For electrical products, the Product Safety Act (製品安全四法) and PSE certification requirements apply. For products intended for children, construction materials, gas appliances, and other regulated categories, sector-specific compliance is a prerequisite for legal sale, not just a commercial requirement.
For ACP specifically:
(d) Ensure the manufacturer's product liability insurance explicitly covers the manufacturer's role as named importer in Japan. The Japan-based importer liability is a distinct insured status from the manufacturer's home-market exposure.
(e) Build product recall procedures that are operable in Japan. The manufacturer, as the party with statutory obligations under the Consumer Product Safety Act (消費生活用製品安全法), must be capable of initiating recall actions, notifying the ministry, and coordinating product retrieval from the Japan market. Without a Japan commercial presence, these operations require a designated Japan-based coordinator.
For IOR specifically:
(f) Review the indemnification provision in the IOR service agreement carefully. Confirm that it covers product liability claims arising in Japan from defects in the manufacturer's goods, not only from errors in Aplash's customs handling.
(g) Confirm Aplash's role as re-seller and named importer is addressed in the manufacturer's product liability insurance as a covered entity under the indemnification framework. Some liability insurers require disclosure of downstream re-sellers in the covered distribution chain.
The Legal Question That Belongs to a Qualified Attorney
Product liability law in Japan is complex and fact-specific. The analysis above describes the structural framework: who is the importer, who is the manufacturer, what roles carry PL Act liability. The application of that framework to a specific product, a specific harm, and a specific distribution chain is legal analysis, not customs compliance work. The choice between IOR and ACP affects legal exposure in Japan. That choice should be made with an understanding of the liability implications, and for manufacturers in high-risk product categories, the implications should be reviewed with a qualified attorney (弁護士) in Japan before the first shipment, not after the first claim.
