Other Engine Equipment Manufacturing
NAICS 333618 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in manufacturing internal combustion engines (except automotive gasoline and aircraft).
Start the review with products liability.
For Other Engine Equipment Manufacturing, the saved research highlights products liability, employee injuries, 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 engines are produced — diesel, natural gas, multi-fuel — and what end-use applications are they designed for?
- Are products sold direct to end users, through OEM channels, or to distributors, and in what geographies?
- What quality control and product testing protocols are in place, and is ISO or similar certification maintained?
- Has there been any prior products liability loss history, including claims or incidents not yet in suit?
- Are there any on-site fuel storage, machining fluid handling, or emissions testing operations that could create environmental exposure?
- For Other Engine Equipment Manufacturing, what should the underwriter know about engines produced for high-hazard end-use applications such as mining, explosive-atmosphere environments, or emergency power systems?
- For Other Engine Equipment Manufacturing, what should the underwriter know about prior products liability losses, particularly any involving engine failure in the field causing bodily injury or significant property damage?
- For Other Engine Equipment Manufacturing, what should the underwriter know about lack of documented quality control, iso certification, or product testing protocols?
