Product liability insurance pays when what you sold hurts someone or damages their property. Not your advice, not your workmanship in the abstract — the product itself: the supplement that sickens, the bracket that fails, the toy that breaks the wrong way. For most businesses it lives inside the commercial general liability policy as the products-completed operations coverage part, and for product-heavy businesses it is bought as a dedicated policy with its own limits and its own underwriting interrogation. This page covers how the liability actually works — strict liability, the three defect families, everyone the chain of distribution drags in — who needs dedicated coverage, and what underwriters price when they look at your product.
The legal shape: you can be liable without being careless
Product liability runs on strict liability in most of the United States. A manufacturer — and often everyone who sold the product after them — can be liable for harm from a defective product without the injured person proving negligence at all. The defect is the case. Defects come in three families. Manufacturing defects: the product that left the line wrong — the batch contaminated, the weld missed, the unit assembled with the wrong part. Design defects: every unit made exactly as intended, and the intention itself is unreasonably dangerous when weighed against a feasible safer design. Warning defects: the product was made right and designed defensibly, but its instructions and warnings failed to disclose a risk a user needed to know — the family behind a remarkable share of real claims, because paper is cheaper to attack than engineering. Negligence and breach-of-warranty claims ride alongside, but strict liability is the engine: it is why a careful company with a good product can still need this coverage desperately the one time the line, the drawing, or the label fails.
Everyone in the chain gets sued
Plaintiffs sue the whole ladder. The manufacturer, yes — and the importer who brought the product in (importers are routinely treated as the manufacturer for practical purposes, especially when the actual maker is overseas, judgment-proof, or gone), the distributor who warehoused it, the retailer who sold it, and the marketplace that hosted the sale. Many states have “innocent seller” protections that can dismiss a non-manufacturer seller who merely passed a sealed product through — with exceptions that swallow careless defendants, and with defense costs accruing from day one regardless. The importer’s position deserves its own sentence, because it is the modern fact pattern: if you import it, brand it, or white-label it, the law and the plaintiff’s bar will generally treat the product as yours, whatever your supplier agreement says — and your contractual indemnity from a foreign manufacturer is worth precisely what you can collect across an ocean.
Where the coverage lives
Inside the CGL, the products-completed operations hazard is the home address — coverage for bodily injury and property damage arising from your product or your completed work, after it has left your hands, subject to the aggregate limit that exists specifically for this hazard. The general liability guide on this hub covers that structure. Dedicated product liability policies are bought when the product is the risk: manufacturers, importers, supplement and food businesses, toy and juvenile-product makers, medical-adjacent products, and sellers whose platform or retail contracts demand named, evidenced limits. The contract demand is its own modern driver — Amazon, for example, requires sellers who pass its monthly sales threshold to carry liability coverage including products liability and to name Amazon as an additional insured; big-box retail and distribution agreements impose their own versions, with certificates tracked like rent.
What it does not cover: your own product
Product liability pays for the harm the product does — not for the product. The cost of repairing, replacing, or recalling the defective thing itself is not bodily injury or property damage to others, and the CGL’s “your product” and “impaired property” exclusions guard that line. The recall itself — notification, logistics, destruction, business interruption from a pulled line — is a separate insurance product, product recall coverage, bought deliberately and mostly by food, beverage, consumer-goods, and auto-supply businesses. Companies discover this boundary at the worst moment with metronomic regularity: the claim pays, the recall bankrupts. Both decisions belong in the same placement conversation, and the distinction is an FAQ below because it is the most expensive misunderstanding in this line.
What underwriters price
The product’s hazard class is the opening bid. Ingestibles, products for children, products that hold people up or stop vehicles, products with lithium batteries — these classes start in a different room from housewares. Then revenue and units in the field (exposure is products × time), distribution breadth, claims and recall history, and the quality system an underwriter can document: design review, testing against the governing standards, supplier controls, batch traceability, complaint monitoring, and warnings drafted by someone who has read the failure-to-warn case law. Two makers of the same product pay different prices in proportion to how well they can prove they run those systems. In this line, quality documentation is not compliance decoration; it is the premium.
Frequently asked questions
What is product liability insurance?
Coverage for bodily injury and property damage caused by products you manufacture, import, distribute, or sell. For most businesses it sits inside the commercial general liability policy as products-completed operations coverage; product-heavy businesses buy it as a dedicated policy with its own limits.
What is the difference between product liability and E&O?
The source of the harm. Product liability answers when a physical product injures someone or damages property. Errors and omissions (professional liability) answers when your services or advice cause a client’s financial loss. A defective valve is product liability; the engineering opinion that specified it may be E&O — some claims plead both, which is why the programs are placed together and read together.
Does product liability cover recalls?
No. Liability coverage pays for harm the product caused to others; the costs of the recall itself — notification, shipping, destruction, lost business — require separate product recall insurance. The two are placed together by businesses whose products could plausibly be recalled.
Who needs product liability insurance?
Anyone in the chain of distribution: manufacturers, importers and white-labelers (who are treated as manufacturers in practice), distributors, and retailers. Marketplaces and retail contracts increasingly require it with named limits and additional-insured status — Amazon imposes it on sellers past a monthly sales threshold, and most large retail agreements do the same.
