Product Liability and Warranty Litigation in Hong Kong

Hong Kong product liability may arise in both tort (negligence) and contract, with criminal aspects under sectoral product safety statutes. Liability in negligence is fault-based. There is no enacted strict liability regime.

In the contractual sphere, the Sale of Goods Ordinance (Cap. 26) (SOGO) forms a central pillar of Hong Kong’s product liability regime, particularly for warranty‑type or defective‑goods disputes. Under SOGO, implied conditions require that goods be of merchantable quality, fit for purpose, and correspond with their description or sample. Breach of these implied terms does not depend on the seller’s fault or knowledge, and liability may arise even where the seller has exercised all reasonable care and was not negligent. However, this should be distinguished from “strict liability” in the product liability sense; SOGO imposes liability for non-conformity with contractual or statutory quality standards, but claimant must still prove breach of the relevant implied condition. This makes SOGO‑based warranty liability a significant and distinct avenue for product‑related claims, especially where defects do not amount to safety risks but still fall below contractual or statutory quality standards.

It is common for claims to arise concurrently in both tort and contract.

Hong Kong has no single statutory definition of “product”; different legislation applies to different product categories (for example, consumer goods under the Consumer Goods Safety Ordinance (Cap. 456), toys under Toys and Children’s Products Safety Ordinance (Cap. 424), pharmaceuticals under the Pharmacy and Poisons Ordinance (Cap. 138), and dangerous goods under the Dangerous Goods Ordinance (Cap. 295). 

In negligence, the duty of care has been applied to a wide range of items, including “computer software,” so software can fall within the scope of products for tort claims. 

Consumer-focused statutes (e.g., Consumer Goods Safety Ordinance, Cap. 456) regulate goods “ordinarily supplied for private use or consumption,” which distinguishes consumer goods from other categories, whereas SOGO applies to “all chattels personal other than things in action and money.” 

Negligence

In negligence, any person who suffers personal injury or property damage as a result of a defective or unsafe product may bring a claim, including buyers, hirers, users, employees, bystanders and anyone else. 

Contract and warranty

Contractual claims are generally confined to immediate contracting parties due to privity, subject to limited exceptions, such as where an agency relationship can be established, but success in such cases is rare.

Under SOGO, buyers may sue for breach of implied conditions, including merchantable quality, fitness for purpose, and correspondence with description or sample. These SOGO implied terms operate independently of fault, meaning the seller may be liable even if they exercised reasonable care and were not negligent. As a result, warranty liability under SOGO is a major avenue for defective‑goods and product quality disputes, especially in claims involving economic loss or non‑safety‑related defects.

Claims on behalf of deceased persons

Product-related claims may also be brought on behalf of deceased persons through estate or fatal accident claims, subject to the applicable statutory framework and limitation rules.

In Hong Kong, the types of damages recoverable in product liability and warranty claims depend on whether the claim sounds in negligence or in contract. 

Negligence

In negligence, damages are recoverable for personal injury and property damage; pure economic loss is recoverable where there is sufficient proximity arising from a special relationship between the parties.

Non‑material losses such as pain and suffering, loss of amenities, loss of earnings, and future care costs are recoverable in personal injury cases.

Contract and warranty

In contract, all losses flowing from the breach are recoverable unless too remote (subject to the usual principles of remoteness and mitigation). This includes:

• Direct losses: e.g. refund of purchase price, repair or replacement costs
• Consequential losses: lost profits, wasted expenditure, business interruption, logistic losses, and other downstream commercial impacts
• Non-material losses: only in exceptional circumstances where such loss was within the contemplation of the parties

The seller’s lack of fault is irrelevant where a statutorily implied term exists in a consumer transaction.

In particular, under SOGO, breach of an implied condition gives rise to robust remedies. The buyer may reject the goods and treat the contract as repudiated, in addition to claiming damages. A seller may be liable even where they exercised reasonable care or had no knowledge of the defect. As SOGO claims often arise in commercial supply chains, recoverable damages frequently include lost profits, recall costs, repackaging costs, reputational loss (if quantifiable), and contractual liabilities incurred downstream.

Punitive damages

Punitive or exemplary damages are rarely awarded in Hong Kong product liability matters. They are generally confined to deliberate wrongdoing (e.g., defamation and trespass).

A product may be considered “defective” in tort where it is unsafe compared with what users are entitled to expect, and in contract/warranty where it fails to meet the express or implied quality standards required under SOGO or the parties’ agreement, even if the product is not unsafe and even if the seller exercised reasonable care.

Defect under product liability in tort

In tort, a product is likely “defective” if it is substantially less safe than comparable products on the market, or where it presents an unreasonable or unexpected risk of injury or property damage due to a manufacturing defect, a design defect, or a failure to provide adequate warnings or instructions.

Claimants must prove, on the balance of probabilities, that: the product was defective; the defect arose in the course of manufacturing or production; and there was a breach of duty in failing to take reasonable care. 

Where the precise mechanism of the defect is unknown, res ipsa loquitur may assist in appropriate cases by allowing the court to infer negligence from the circumstances.

Defect under warranty litigation and contract

In warranty and contractual claims, defect” has a broader and different meaning. A product may be “defective” even if it is not dangerous, so long as it fails to meet contractual or statutory quality standards.

A product is considered defective if it fails to comply with any implied condition, including:

• Merchantable quality: goods must be free from defects (including minor defects), durable, safe, and of acceptable quality given their description, price, and circumstances;
• Fitness for purpose: including any specific purpose communicated to the seller;
• Correspondence with description; and
• Correspondence with sample.

A product may be defective without causing injury, e.g., non‑conforming goods, substandard components, counterfeit items, failure to meet agreed specifications.

The claimant bears the burden to prove negligence and causation on the balance of probabilities; negligence may sometimes be inferred from the existence of a defect (res ipsa), but compliance with standards does not automatically absolve liability.

In warranty and SOGO‑based claims, the claimant must prove non‑conformity with the contractual or implied conditions (e.g., merchantable quality, fitness, description), but need not prove fault, as liability turns on breach of condition rather than negligence.

Courts assess reasonableness of safety and care in manufacture, design, warnings/labelling, instructions, component selection, and foreseeable risks/misuse, with higher standards where risks are higher. 

Compliance with regulations/industry standards is relevant but not determinative; regulatory compliance is not a defence to a failure-to-warn claim, and manufacturers must decide and provide adequate warnings/instructions notwithstanding regulatory baselines.

In warranty litigation, the focus is not on “safety” but on conformity with contractual and SOGO quality standards, even where the goods pose no safety risk.

Liability in negligence extends beyond manufacturers to designers, suppliers, assemblers, installers, repairers, importers/wholesalers, utilities suppliers, and even producers of defective instructions/leaflets and safety certifiers, depending on the role and fault.

Retailers and distributors may be liable in both contract and tort depending on knowledge/opportunity to inspect, handling, and whether they followed and passed on warnings/instructions. Liability may be negated where a reasonable intermediate inspection by a party in the supply chain or the end user would have been anticipated and would likely have uncovered the defect, or where proper adherence to provided instructions would have avoided the harm.

For warranty/SOGO claims, liability generally sits with the contracting seller in the supply chain, regardless of where the defect originated, as SOGO imposes liability based on non‑conformity rather than fault.

Where damage is caused by the negligence of more than one party in the product supply or service chain, liability may be apportioned among joint tortfeasors according to their respective degrees of fault. The courts recognise that responsibility may lie with multiple actors, such as manufacturers, installers, repairers or employers, and will assess contribution based on causative potency and blameworthiness. A defendant held liable may seek contribution or indemnity from other responsible parties in appropriate circumstances.

Where multiple tortfeasors cause distinct injuries to the claimant, each is liable only for the harm attributable to its conduct. In the absence of clear evidence permitting differentiation, damages may be divided equally among the responsible parties.

In warranty and SOGO‑based claims, apportionment operates differently: liability to the buyer generally rests with the contracting seller, irrespective of where the defect originated in the manufacturing or distribution chain. The seller may then seek contractual or indemnity rights upstream, but as between the buyer and seller, breach of an express or implied condition (such as merchantable quality or fitness for purpose) is not diluted by the actions of upstream parties. Recent decisions, reinforce that SOGO liability turns on non‑conformity of the goods delivered under the specific contract, and not on the degree of fault of other entities in the supply chain.

Under the tort of negligence, various defences may be available, which include: misuse (particularly unforeseeable or materially different use), volenti non fit injuria, contributory negligence (e.g., ignoring clear instructions/warnings), and arguments relating to intermediate examination when reasonably likely to reveal defects. 

Regulatory compliance is not a complete defence to failure-to-warn. 

In warranty/SOGO litigation, most negligence‑based defences do not apply. The primary issue is whether the goods conformed with the relevant conditions; a seller cannot rely on having exercised reasonable care or lacking knowledge of the defect.

The Consumer Goods Safety Ordinance (Cap. 456) provides specific statutory defences to criminal liability for supplying non-compliant goods, including a due diligence defence and defences applicable to goods in transit, transhipment, or manufactured exclusively for export.

For negligence causing death or personal injury, liability cannot be excluded or restricted; for other loss/damage, exclusion is subject to a reasonableness test under the Control of Exemption Clauses Ordinance (Cap. 71) (CECO).

Exclusion of liability in sale of goods contracts is in principle permitted under SOGO but subject to the CECO constraints and strict construction by the courts. Exemption clauses that exclude liability for death and personal injury are usually not effective. For those that exclude liability for financial loss or damage to property, their validity is subject to a reasonableness test – that the term was a fair and reasonable one to be included having regard to the circumstances which were, or ought reasonably to have been, known to or in the contemplation of the parties when contract was made.

Exclusions attempting to remove liability for implied conditions of merchantable quality or fitness are ineffective in consumer cases and strictly construed in commercial ones, reflecting courts’ unwillingness to dilute SOGO quality protections.

Under the Limitation Ordinance (Cap. 347), actions founded on contract or negligence are generally subject to a six‑year limitation period from the date on which the cause of action accrued. In cases involving damages for personal injury, including death, proceedings must ordinarily be commenced within three years from the date on which the cause of action accrued or from the date of the claimant’s knowledge, if later. The courts retain a discretion to disapply the limitation period in personal injury cases where it is equitable to do so, taking into account the prejudice to the parties.

Where the defendant has deliberately concealed a material fact relevant to the cause of action, the limitation period does not commence until the claimant discovers, or ought reasonably to have discovered, the concealment.

Yes. Safety and suitability requirements are often treated as implied terms in sale contracts, including conditions of correspondence with description, merchantable quality, and fitness for purpose under SOGO. Although SOGO uses the phrase “condition or warranty”, these terms are generally treated as implied conditions, breach of which entitles the buyer to reject the goods and claim damages.

Contractual claims may proceed concurrently with tort claims; privity generally confines contractual claims to immediate parties. 

SOGO defines merchantable quality by reference to whether goods are:

• as fit for the purpose or purposes for which goods of that kind are commonly bought;
• of such standard of appearance and finish;
• as free from defects (including minor defects);
• as safe; and
• as durable,

as it is reasonable to expect having regard to any description applied to them, the price (if relevant) and all the other relevant circumstances.

For breach of a condition (e.g., implied condition of merchantable quality/fitness/description), the buyer may reject the goods, treat the contract as repudiated, and claim damages; for a breach of warranty, the buyer may claim damages only. The contractual terms may restrict remedies for warranty breach to specific relief such as repair or replacement within a defined warranty period.

The seller’s lack of negligence is irrelevant where a statutorily implied term exists in a consumer transaction; all losses are recoverable unless too remote (subject to mitigation).

Punitive or exemplary damages are generally not recoverable for breach of contract or breach of warranty claims. Contractual remedies are compensatory in nature and are intended to place the claimant in the position they would have been in had the contract been properly performed. Punitive damages are confined to exceptional categories of deliberate wrongdoing and do not ordinarily arise in product warranty disputes.

Product liability litigation in Hong Kong is governed by the general rules of civil procedure on discovery and disclosure. Parties are required to disclose all documents that are relevant and material to the issues in dispute, unless privileged.

Hong Kong has no class action procedure. Claims are individual rights; actions may be consolidated or heard together. A representative action is available for parties with the same interest, but consumer associations cannot sue on behalf of multiple claimants. Accordingly, claimants typically pursue individual actions even where similar issues arise across multiple cases.

Product liability claims in Hong Kong are most commonly funded privately by claimants. In appropriate cases, legal aid may be available to eligible claimants, subject to applicable means and merits tests. 

While third‑party litigation funding is permitted and regulated in certain contexts, its availability in ordinary civil litigation, including product liability claims, remains limited.

Costs in product liability litigation in Hong Kong generally follow the event. A successful claimant will usually be entitled to recover a portion of its reasonable legal costs from the unsuccessful party, subject to taxation by the court.

Contingency fees, success fees and damages‑based agreements are generally prohibited in Hong Kong litigation, and lawyers are not permitted to charge fees calculated by reference to the outcome of court proceedings. Limited exceptions have been introduced under recent reforms permitting outcome‑related fee structures in arbitration and related proceedings, but these do not ordinarily apply to product liability claims pursued through the courts.

Rickeed Industries Ltd v Hong Kong Tohkoh Co Ltd [2026] HKCA 105

In this appeal, the plaintiffs alleged that two shipments of acrylic sheets were defective and sought damages for breach of contract. The Court of Appeal overturned the trial decision, finding no shipment-specific evidence proving that the goods under the relevant purchase orders were defective and holding it was unnecessary to determine whether the goods failed the implied SOGO conditions, given the absence of proven defects. The Court also held that the plaintiffs had not proved any loss, as lower resale prices were not shown to be linked to defects rather than market factors. The decision underscores that buyers must establish defects and causation with clear, objective evidence, tied to the specific shipments in question, not by relying on historical complaints or general quality concerns.

Dialectic PR LLC v Thinking Group Ltd [2025] HKCFI 1555

The plaintiff sued for breach of several contracts after receiving shipments of KN95 masks that, according to independent laboratory testing, failed to meet agreed standards and were mislabelled as compliant. The Court held that the seller breached both express contractual obligations (compliance with specifications and accurate packaging) and in respect of certain shipments the implied conditions under SOGO s.16 (merchantable quality and fitness for purpose); one shipment was found defective only on the basis of mislabelling, and the claim for another shipment was dismissed for lack of evidence. As the non-conforming goods disrupted the plaintiff's sub-sales, the Court awarded lost profits and wasted storage expenses. The case demonstrates the Court's readiness to enforce contractual quality standards strictly and to accept independent testing as reliable proof of non-compliance for the shipments where defects were established.

Although Hong Kong does not currently have a statutory strict liability regime for defective products, the Law Reform Commission has recommended introducing statutory strict product liability to supplement the common law. It has also proposed an opt‑out class action regime to be introduced in phases, initially for consumer claims such as product liability, in 2012. A cross‑sector Working Group on Class Actions has been established and a consultancy study was commissioned in August 2021, but the timetable for implementation, if any, remains uncertain.
