Owners ask us for “products liability” all the time, and then ask where their products-liability policy is — and the honest answer tends to surprise them: for most machine shops and manufacturers, there is no separate products-liability policy at all. Products liability is part of your general liability. It lives inside the standard commercial general liability coverage form as the products-completed operations hazard, the piece that answers when a product you made causes third-party harm after it leaves your control. This post explains what people actually mean by products liability, why it sits inside general liability rather than beside it, and the two narrow situations where a manufacturer genuinely needs something the general liability form was never built to pay.
The short version: products liability is the products side of your general liability policy, not a stand-alone purchase. What owners call “products liability” is, in the policy itself, the products-completed operations hazard of the general liability coverage form. The cases where you need more than that form are real but specific — the cost of recalling a product, and a product that underperforms without injuring anyone — and those route to their own lines rather than to general liability.
Products liability is general liability’s products side
Almost every commercial general liability policy starts from the standard ISO coverage form — typically the occurrence-based one known as CG 00 01. That form covers two broad halves of a business’s third-party exposure. One half is premises and operations: the visitor hurt at your facility, the forklift that backs into a customer’s trailer at the dock, the everyday risk of running a place where outsiders come and go. The other half is the products-completed operations hazard — and that half is products liability.
So when an owner says “I need products liability,” the coverage they are describing is already inside the general liability form, written as a defined term. It is not a footnote and it is not optional language a carrier invents per account; it is part of the architecture of the policy. For a manufacturer it is also the half that matters most, because the premises risk is shared with every business on the block, while the products risk is the one that defines making or machining a thing for a living. Forms, editions, and endorsements vary by carrier, so the practical move is always to confirm what your policy actually carries rather than assume the products side is present and full.
What “your product” and “your work” actually trigger
The products-completed operations hazard turns on two defined terms, and they do a lot of quiet work. “Your product” is, broadly, goods you manufactured, sold, or distributed; “your work” is work you performed and the materials supplied with it. The hazard responds to third-party bodily injury and property damage arising out of those — occurring away from premises you own or rent, after the product has been put to its intended use or the work is complete.
Read that carefully, because it draws the boundary of products liability precisely. The coverage follows the thing you shipped, wherever it goes, once it is in use. It answers the operator hurt by a part that fails in a machine, the property damaged when a component lets go downstream, the end user injured by a finished good far down the chain. What it does not do is pay to rebuild your own defective product: the standard form carries exclusions, framed around “your product” and “your work,” that treat redoing your own scrapped run as a business cost rather than a covered third-party claim. The harm to others is the insured event; making your own bad output good again is not. That line is real and constantly misread, which is exactly why knowing what counts as your product or your work is worth doing before a claim, not during one.
When a manufacturer needs more than the general liability form
Because products liability already lives inside general liability, the real question for an owner is not “do I have a products-liability policy” but “where does general liability stop.” It stops in two places, and both are common enough for a manufacturer that naming them honestly is the whole point.
The first seam is the cost to recall the product. When a defect means the product has to come back out of the market, the expense of that recall — customer notification, shipping it back, disposal, and replacement — is a first-party cost, not a third-party claim, and general liability does not pay it. That is what product recall coverage is for. Products liability answers the lawsuit over the harm; recall coverage pays to get the defective product out of circulation. Different bills, different lines.
The second seam is a product that underperforms without hurting anyone. When a product is out of spec — it fails to do what the contract said, leaves the customer with a financial loss, but injures no one and damages no other property — the standard form’s exclusions around impaired property and property that has not been physically injured typically apply, so general liability does not respond. That pure financial-loss exposure runs to manufacturers errors and omissions, a professional-liability line distinct from the bodily-injury side products liability covers. Three exposures, three lines — the harm, the recall cost, and the financial loss — and we draw the full picture in the three products coverages distinguished so a manufacturer with real products exposure carries all three rather than assuming one form answers for everything.
Real-World Scenario: A shop machines a run of brackets to a customer’s print and ships them. Months later, one fails in the customer’s assembly out in the field and injures an operator — that downstream third-party injury, arising out of your product, is products liability, and it is answered inside your general liability as the products-completed operations hazard. If instead the customer had to pull the whole run of finished assemblies back off the market, the cost of that recall would route to product recall, not general liability. And if the brackets had simply tested out of tolerance and left the customer with a financial loss but injured no one, that runs to manufacturers errors and omissions. Same part, one general liability policy, and two exposures that fall outside it.
There is one more thing worth checking, because it is quiet and consequential. Some policies carve the products-completed operations hazard out of the base form entirely with an exclusion endorsement — in ISO’s system, a form along the lines of CG 21 04. For many businesses that endorsement is harmless; for a manufacturer it removes the very coverage the shop or plant relies on most. Whether that endorsement is on your policy is exactly the kind of thing worth reading before you need it.
One more wrinkle: how the policy is triggered
Even once you know products liability lives inside general liability, the form your policy uses changes how a late-surfacing claim is handled. The standard CG 00 01 is written on an occurrence basis; there is also a claims-made version, the CG 00 02, that responds based on when a claim is reported. Because a defective product can surface years after it ships, that distinction matters more for a manufacturer than for almost any other class — enough that it has its own write-up in occurrence versus claims-made for manufacturers. The short read is that the long products tail usually makes occurrence-based coverage valuable, but the right answer depends on the form your policy actually carries.
Why it matters for your operation
If you make or machine a product, the instinct to go shopping for a separate “products-liability policy” usually sends you looking for something that is already in your general liability — and the more useful work is making sure the products-completed operations side of that policy is actually present, full, and written with the manufacturing tail in mind. We read the hazard against the products you actually ship, check the occurrence-versus-claims-made trigger and the separate aggregate, look for the endorsement that can quietly carve the hazard out, and write the recall and errors-and-omissions seams as their own lines rather than pretending one form answers for all three. When you are ready, start a quote and tell us what you make or machine, or read the full general liability and products liability page to see how the products side fits. Forms and editions vary by carrier, so the right move is always to confirm what your policy actually carries rather than assume.
