What Does Manufacturing Insurance Cost for a Ann Arbor Factory?
A small Ann Arbor shop generally pays $3,000 to $6,000 annually for general liability, property, and workers’ compensation together, climbing to $10,000 to $25,000 for mid-size operations that add product liability and equipment breakdown.
| Facility Size | Typical Annual Premium | What Drives It |
|---|---|---|
| Small shop (under 20 employees) | $3,000 to $6,000/yr | Small-shop coverage built from the three core lines |
| Mid-size plant (20 to 150 employees) | $10,000 to $25,000/yr | Layers in equipment breakdown and product liability as OEM supply relationships grow |
| Large or high-risk facility | $50,000 to $100,000+/yr | Facilities with heavy machinery, hazardous material classifications, or several locations |

What Coverage Types Does a Manufacturer Need?
A Ann Arbor manufacturer typically needs five coordinated coverage lines:
General Liability
Third-party injury and property damage protection.
Commercial Property
Your building, equipment, and inventory.
Workers’ Compensation
Coverage for employee injuries on the job.
Equipment Breakdown
Mechanical and electrical failure of production machinery.
Product Liability
Coverage for parts and products after they ship.

Product Liability
Coverage for parts and products after they ship.
Michigan’s product liability framework under MCL 600.2946 is genuinely more manufacturer-favorable than most states, requiring proof of a feasible alternative production practice. That statute is why product liability coverage still matters for any Ann Arbor manufacturer, even with Michigan’s real manufacturer-favorable defenses in place.
See Michigan Compiled Laws Section 600.2946 for the full statutory text.
These five lines apply the same way statewide, so see our full Michigan manufacturing insurance overview for requirements that go beyond Ann Arbor.

- Cell therapy manufacturing operates under one of the most tightly regulated FDA frameworks of any manufacturing category, carrying product liability and quality-control exposure a generic policy is not built to cover.
- Ann Arbor’s real manufacturing identity includes genuine biomanufacturing alongside its better-known research and technology base, not a purely academic or software-driven economy.
Why Ann Arbor Manufacturers Choose Manufacturing Insurance Group
We work with manufacturers exclusively
Every policy we write goes to a manufacturer. We are not a general commercial agency with a manufacturing sideline, so cell therapy and biomanufacturing exposure is already familiar before we ask a single question.
We place your risk with carriers built for manufacturing specifically
A standard small business platform simply does not carry markets for cell therapy and biomanufacturing risk. We place Ann Arbor manufacturers with the specialty carriers that do.
Your rate reflects your real production process, not a guess
A Ann Arbor operation’s cell therapy and biomanufacturing process is what drives its real risk, not its size. We underwrite the equipment and workflow you run.
