Product Liability
Product liability is the legal responsibility a manufacturer, distributor or seller can face when a defective product injures someone or damages property. Product liability insurance is the coverage that may pay defense costs and covered damages from such claims, subject to the policy's terms.

How product liability works
Product liability is a body of law that lets an injured person sue over a defective product. Claims are commonly grouped by theory: a manufacturing defect (the item departed from its intended design), a design defect (the design itself is unsafe), a marketing defect such as inadequate warnings or instructions, and breach of warranty. Many claims proceed on strict liability, meaning the plaintiff does not have to prove the company was careless, only that the product was defective and the defect caused the harm.
Anyone in the chain that designs, makes, distributes or sells a physical product can be a target, and partners, retailers or investors sometimes require proof of coverage before doing business. Product liability insurance is the insurance side: it responds to covered claims of bodily injury or property damage arising from the insured's products. It is sometimes included in a general liability program and sometimes arranged separately, and recall costs are typically a different coverage.
Example
A hypothetical consumer-hardware company sells a battery-powered device. A customer alleges that the battery overheated and burned their home. The claim is a product liability claim. The company's liability program may respond to the defense and covered damages, subject to its limits, retention and exclusions, while the cost of recalling the device would generally require separate recall coverage.
What to watch for
- Trigger and timing: policies may be occurrence-based or claims-made, which affects coverage for claims that arrive years after a sale. See occurrence policy and claims-made policy.
- Recall is separate: recall expenses are generally addressed by separate recall coverage, not a standard liability policy.
- Supply chain: retailers, partners and investors may require proof of coverage as a condition of doing business.
- Products versus services: injury from software or advice may fall under errors and omissions coverage instead.
Product liability vs. related terms
- General liability. Commercial general liability is the broad policy for third-party bodily injury and property damage. It often includes products-completed operations coverage, so for many companies product liability is a part of the general liability program, subject to its exclusions. Some buyers arrange a separate product liability policy when the general policy does not fit the exposure.
- Product recall. A recall is the cost of pulling products from the market, notifying customers and replacing units. A liability policy responds to claims against you for injury or damage. Recall expense is generally a separate, first-party type of coverage.
- Professional or technology E&O. Professional liability responds to financial loss from services, advice or software failures. Product liability responds to bodily injury or property damage from a physical product. For connected devices the line can blur, so read the wording on both policies.
- Warranty. Breach of warranty is one legal theory behind a product claim. The cost of repairing or replacing your own defective product is commonly excluded from liability policies, because it is seen as a business cost and not injury to others.
Second example: a robotics company
A hypothetical company sells autonomous warehouse robots. After a software update, one robot moves unexpectedly, injures a worker and damages a rack of inventory. The customer and the worker bring claims that allege a design defect and inadequate warnings. A liability policy may respond to the defense and to covered damages for the bodily injury and property damage, subject to its limits, retention and exclusions. Whether a software or technology exclusion affects the claim depends on the exact wording. The cost of fixing the fleet or recalling the update would be a separate matter, and any claim about lost productivity at the customer could fall under a different policy.
Questions to ask your broker or underwriter
- Does the policy include products-completed operations coverage, and is it subject to its own aggregate limit?
- Are there exclusions for software, artificial intelligence, batteries or specific product types?
- Do the territory terms cover products that are sold, shipped or used outside the United States?
- Are defense costs inside or outside the limit?
- Do distributors, retailers or customers require additional insured status, and can we issue a certificate of insurance that matches the contract?
- Is an umbrella or excess layer needed to reach the limits that contracts or investors expect?
Why it matters for technology, AI, fintech and digital-asset companies
Hardware, robotics, drones and other physical AI companies put devices into the world, which creates bodily injury and property damage exposure that software-only companies do not face. Investors and enterprise buyers often ask for evidence of coverage. Learn more on our product liability coverage page and our physical AI and hardware page.
Physical AI is the sharpest case. When software decides how a device behaves, a claim can allege both a product defect and a failure of the software, and the policies may point at each other. Companies that build AI features should read how their liability and AI liability wording treat injury caused by model output, and see AI liability coverage and general liability for general background. Fintech and digital-asset companies usually have little product liability exposure unless they ship physical devices such as payment terminals or hardware wallets. Their main exposures sit under professional, cyber and management liability policies instead.

Frequently asked questions
What is product liability?
Product liability is the legal responsibility a manufacturer, distributor or seller can face when a defective product injures someone or damages property. Product liability insurance is the coverage that may pay defense costs and covered damages from such claims, subject to the policy's terms.
What are the main types of product defects?
Claims typically allege a manufacturing defect, where a unit departs from its intended design, a design defect, where the design is inherently unsafe, or a marketing defect such as inadequate warnings or instructions. Breach of warranty is another common theory. Rules differ by state.
Who can be held liable for a defective product?
Depending on state law and the facts, liability can reach designers, manufacturers, component makers, distributors and retailers in the supply chain. Contracts between the parties often allocate responsibility further, which is one reason companies are asked to show insurance.
Does product liability insurance cover recalls?
Generally no. Recall expenses such as notification, shipping, destruction and replacement are usually addressed by separate product recall coverage. Product liability insurance typically responds to third-party bodily injury or property damage claims, subject to the policy terms.
Is product liability insurance the same as general liability?
Not exactly. General liability is the broad third-party policy, and it often includes products-completed operations coverage that responds to product claims. Some companies buy a separate product liability policy or add limits. Whether your products are covered depends on the policy wording and its exclusions.
Do software and AI products count as products for product liability?
It depends. Courts and policies often treat stand-alone software as a service, while software built into a physical device can be considered part of the product. This area is still developing, so review how your policies define products and whether they exclude software or AI-related causes.
Does a hardware startup need product liability insurance?
It is often required in practice. Retailers, distributors, contract manufacturers and enterprise customers commonly ask for proof of coverage in contracts, and investors may expect it. Whether you need it, and at what limits, depends on what you sell and the contracts you sign.
How long after a sale can a product liability claim be made?
It varies by jurisdiction and by the type of claim, because time limits for bringing a suit differ. A claim can arrive years after a product was sold, which is why the policy trigger, occurrence or claims-made, and the retroactive date on claims-made forms matter.
