Start the review with products liability.
For Machine Tool Manufacturing, the saved research highlights products liability, completed operations, industrial property. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What types of machine tools are manufactured — metal cutting, metal forming, or both — and what industries are the primary end users?
- Does the operation include field installation, commissioning, or ongoing service at customer facilities?
- Are products distributed domestically, exported, or both?
- What are the approximate values of machinery, tooling, and work-in-process inventory on premises?
- Has the business had any products liability claims or product-related customer complaints in recent years?
- For Machine Tool Manufacturing, what should the underwriter know about products destined for aerospace, defense, medical device, or nuclear applications where failure consequences are severe and litigation exposure is elevated?
- For Machine Tool Manufacturing, what should the underwriter know about prior products liability claims, particularly involving machine guarding failures or operator injuries at customer facilities?
- For Machine Tool Manufacturing, what should the underwriter know about field installation or commissioning services at customer industrial sites, which can blur the products/completed operations line and increase severity?

Machine tool manufacturers design and produce metal cutting and metal forming equipment — lathes, milling machines, grinders, stamping presses, drilling machines, and related metalworking machinery — sold primarily to industrial manufacturers and fabricators. Operations typically involve heavy machining, assembly, quality testing, and sometimes installation or commissioning at customer facilities.
