Michigan Wholesale Distributor and Warehouse Insurance: Products, Stock and Goods in Transit

Michigan wholesale distributor insurance has to solve a problem manufacturers and retailers do not have. You are legally in the chain of a product you never designed or built. Your stock value swings by season. A meaningful share of what sits in your building belongs to somebody else, and a meaningful share of your revenue is on a truck at any given moment. A standard commercial package priced off square footage misses most of that. Here is how a distributor's program is actually built, and where the expensive gaps are.

You did not make it, but you are still in the lawsuit

When a product hurts somebody, the plaintiff typically sues everyone in the chain: the manufacturer, the distributor and the retailer. As a Michigan distributor, your first line of defense is statutory.

Michigan's product liability statute, MCL 600.2947(6), provides that a seller other than the manufacturer is not liable in a product liability action unless the plaintiff establishes one of two things: that the seller failed to exercise reasonable care, including breach of any implied warranty, with respect to the product, and that failure was a proximate cause of the harm; or that the seller made an express warranty about the product, the product failed to conform to it, and that failure was a proximate cause of the harm. In practical terms, a plaintiff generally has to point at something the distributor itself did or failed to do, rather than simply proving the product was defective.

That is a genuinely favorable rule. It is not a force field, and there are several ways distributors walk out from behind it:

• You made claims about the product. Sales sheets, spec comparisons and catalog copy can become express warranties. The second prong is the one distributors trigger most often, and usually through marketing.
• You altered, repackaged or relabeled it. The further you move from pure pass-through, the closer you get to being treated as the manufacturer.
• You are the importer or private-label seller. If the actual manufacturer is offshore and unreachable, courts and plaintiffs look hard at whoever is left.
• You knew. Actual knowledge of a defect plus willful disregard strips a defendant of Michigan's damages caps and several statutory defenses (MCL 600.2949a). By its terms that section does not remove the seller protection itself, but a distributor who knew about a problem and shipped anyway has an obvious difficulty with the reasonable-care prong.

This is a legal question and we are not attorneys — a Michigan products lawyer should read your actual situation. What we can tell you as your agent is that the statutory protection does not stop you from being named, and defense costs on a product suit start accruing on day one. Your general liability policy with a properly sized products-completed operations aggregate is what pays for that defense.

Vendors endorsements cut both ways

CG 20 15, Additional Insured — Vendors, extends your liability policy to a downstream party who sells your product, limited to liability arising out of that product. Two practical points:

• Your customers will demand it from you. Big retailers and OEMs frequently require vendor additional insured status as a condition of the purchase order.
• You should demand it from your suppliers. Being named as an additional insured on your manufacturers' policies is the cheapest product liability protection a distributor can get. Ask for it in writing at onboarding, and re-collect certificates annually.

Know its limits. The endorsement carves out the vendor's own physical or chemical alteration of the product, repackaging beyond narrow exceptions, products labeled or relabeled by or for the vendor, unauthorized express warranties made by the vendor, failure to perform inspections or servicing the vendor agreed to perform, and damage arising from the vendor's sole negligence. If your operation does any value-added work — kitting, assembly, re-boxing — you have moved outside what a vendors endorsement protects, and you need your own products coverage sized accordingly.

Your stock moves; your limit does not

A distributor's inventory in March and its inventory in October are frequently not the same number, and the gap can be large. Insure to the average and you are underinsured at peak, where a coinsurance calculation will find you. Insure to the peak all year and you overpay for eight months.

Two standard solutions:

• Value Reporting Form (CP 13 10). You report actual values on a set schedule and the premium is trued up to what you actually carried. The trade-off is discipline: under-report a value, and the loss payment is reduced in proportion; miss reports entirely, and payment can be limited to the last value you reported. It works well for operations with real inventory reporting and badly for ones without.
• Peak Season Limit of Insurance (CP 12 30). A simpler endorsement that raises the limit automatically during specified periods. Right for predictable, seasonal swings; wrong for volatile ones.

Either way, confirm how your stock is valued. The standard form already values stock you have sold but not yet delivered at selling price less discounts and expenses. Everything still unsold is valued on the ordinary basis, meaning cost rather than what you would have sold it for. On a full warehouse, the gap between those two numbers is worth looking at directly.

Whose goods are in your racks?

This is the coverage question most distributors get wrong. Your commercial property policy insures your business personal property. Property belonging to others in your care, custody and control is handled differently, usually through a limited coverage extension with a sublimit that bears no relationship to the value actually sitting in your building. Meanwhile, your general liability policy typically excludes damage to property in your care, custody or control.

If you store, stage or handle goods owned by customers, you need that exposure addressed on purpose, through warehouse legal liability or bailee coverage. Note the distinction: warehouse legal liability responds when you are legally liable for the loss. A bailee's customers form can be written to respond more broadly. Which one you need depends on your warehouse receipts and your contracts, and it is worth having someone read the limitation-of-liability language in your storage agreement, because it drives how much exposure you actually retain.

Ask a direct question at renewal: what is the most customer-owned inventory that will be in my building at one time this year, and what limit do I carry against it? If nobody in the room knows the answer, that is the finding.

Coverage stops at the dock

Commercial property coverage is tied to described premises. Once product leaves on a truck, that coverage is generally gone. Two pieces fill the gap:

• Motor truck cargo. An inland marine coverage for goods in transit, whether on your own trucks or in the hands of a carrier you hired. If you run your own delivery fleet, this is not optional. If you hire carriers, understand that a motor carrier's legal liability is limited and often less than your goods are worth — contingent cargo coverage exists for exactly that gap.
• Hired and non-owned auto. If employees make runs in their own vehicles, this protects the business against liability from those trips. It is liability only — it does not repair the employee's vehicle and does not cover their injuries, and their personal auto policy may restrict regular business use. See commercial auto versus personal auto in Michigan for where the personal policy stops.

Racking, forklifts and the collapse question

Selective pallet racking loaded thirty feet high is one of the more concentrated property exposures in any building. A forklift strikes an upright, the frame is weakened, and a run of racking comes down weeks later taking inventory with it.

Whether that is covered is genuinely not a question to answer from an article. The collapse provision in the standard causes of loss form is built around the abrupt falling down or caving in of a building or part of a building, triggered by specified causes. Freestanding racking is personal property, not building, and the treatment varies by form edition and carrier. Racking collapse is a well-known industry gap, not a settled inclusion. Have your agent get the answer in writing from your specific carrier rather than assuming either way, and keep your rack inspection and damaged-upright replacement program documented — underwriters price it, and it matters in a subrogation fight against a forklift operator's employer.

Business income for a distributor

Business income coverage after a warehouse fire has a longer horizon than most owners assume, because rebuilding a warehouse is only part of the recovery. Re-sourcing inventory, re-establishing supplier allocations and winning back customers who found another distributor all take time that a twelve-month restoration period may not cover. Consider extended period of indemnity, and consider dependent property coverage if a single supplier or a single large customer represents a concentration you could not absorb. Our post on Michigan business interruption insurance covers how the restoration period is measured.

Michigan context

Wholesale trade is a substantial Michigan employer — roughly 174,700 employees statewide as a 2025 monthly average, not seasonally adjusted, from Bureau of Labor Statistics state and area employment data. In southeast Michigan specifically, distribution is tied tightly to the automotive supply chain, which means many local distributors carry customer-owned inventory, run tight delivery windows, and face contractual requirements written by very large customers. All three of those facts have insurance consequences.

Frequently Asked Questions

Can a distributor be sued for a defective product they did not manufacture?

Yes, you can be named. Michigan's product liability statute, MCL 600.2947(6), provides that a non-manufacturing seller is not liable unless the plaintiff shows the seller failed to exercise reasonable care and that failure caused the harm, or the seller made an express warranty the product did not meet. That is meaningful protection, but it does not prevent being sued, and defense costs begin immediately. This is a legal question for a Michigan products attorney; from an insurance standpoint, general liability with an adequate products-completed operations aggregate is what funds the defense.

What is a vendors endorsement?

CG 20 15 adds a party who sells your product as an additional insured on your liability policy, limited to liability arising out of that product. Large customers commonly require it from their suppliers. Distributors should also ask their own manufacturers for it, so the distributor is protected by the manufacturer's policy. It excludes the vendor's own alteration or repackaging of the product, unauthorized express warranties, and the vendor's sole negligence.

How do I insure inventory that changes value through the year?

Two options. A Value Reporting Form (CP 13 10) lets you report actual values on a schedule and true up premium, but under-reporting proportionally reduces a loss payment. A Peak Season endorsement (CP 12 30) raises the limit automatically during specified periods and suits predictable seasonal swings. Which fits depends on how disciplined your inventory reporting is.

Does my property insurance cover my customer's goods stored in my warehouse?

Generally not adequately. Your property policy insures your own business personal property; property of others is usually covered only under a limited extension with a sublimit. Your general liability policy typically excludes damage to property in your care, custody or control. Customer-owned goods need to be addressed through warehouse legal liability or bailee coverage sized to the most customer inventory you will hold at one time.

Does commercial property insurance cover goods on my delivery truck?

No. Property coverage is tied to your described premises and generally ends when goods leave. Motor truck cargo coverage, an inland marine form, covers goods in transit on your own vehicles. If you hire outside carriers, be aware their legal liability for your freight is often limited well below the value of the goods, which is what contingent cargo coverage addresses.

The bottom line

A distributor's program is judged in four places: whether the products limit and aggregate match what you actually ship, whether the stock limit tracks what is actually in the building, whether customer-owned goods are insured on purpose rather than by accident, and whether coverage follows the freight out the door. Premium comparisons never surface any of them.
