What Coverage Types Does a Manufacturer Need?
For a Sterling Heights manufacturer, five coverage lines usually make up a complete program:
General Liability
Third-party injury and property damage protection.

Your building, equipment, and inventory.

Equipment Breakdown

Product Liability
Coverage for parts and products after they ship.
Michigan law, MCL 600.2946, requires a plaintiff to prove a feasible alternative production practice existed before a manufacturer can be held liable for a production defect. That statute is why product liability coverage still matters for any Sterling Heights manufacturer, even with Michigan’s real manufacturer-favorable defenses in place.
Per Michigan Compiled Laws Section 600.2946‘s state-of-the-art defense provision.
These five lines apply the same way statewide, so see our full Michigan manufacturing insurance overview for requirements that go beyond Sterling Heights.
