National context — Machine Shop insurance overview
A machine shop's defining exposure leaves the building: the parts you make. Products–completed operations — usually the most important part of a machine shop's general liability — answers a claim when a part you machined fails and causes injury or damage. Professional liability is the distinct companion: it responds when a part fails to perform as specified (a tolerance or spec miss) rather than causing bodily harm. Our own quote data shows machine-shop buyers requesting general liability, a BOP and professional liability together — a mix that matches custom-part work to customer prints.
As an industry-typical estimate, a machine shop commonly carries general liability with products-completed operations plus a BOP for the equipment and building, and often professional liability for spec work. No insurance bureau publishes machine-shop premiums, so every dollar here is an estimate; each fact is sourced to a named authority (IRMI, III).

- Professional liability: a part that fails to perform as specified (a spec or tolerance miss) — distinct from bodily-injury product claims. IRMI professional liability.
- General liability: third-party injury and property damage on the shop floor, incl. visitors and delivery drivers. III commercial general liability.
- Workers' compensation: mandatory for a shop-floor workforce in nearly every state. III workers comp.
Tolerances quoted, customer contracts (additional-insured wording) and payroll are primary rating factors.
