All Other Miscellaneous Electrical Equipment and Component Manufacturing
NAICS 335999 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in manufacturing industrial and commercial electric apparatus and other equipment (except lighting equipment, household appliances, transformers, motors, generators, switchgear, relays, industrial controls, batteries, communication and energy wire and cable, wiring devices, and carbon and graphite products). Examples of products made by these establishments are power converters (i.e., AC to DC and DC to AC), power supplies, surge suppressors, and similar equipment for industrial- type and consumer-type equipment.
Start the review with products liability.
For All Other Miscellaneous Electrical Equipment and Component Manufacturing, the saved research highlights products liability, property, workers' compensation. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What specific products are manufactured, and what are their primary end uses — consumer, commercial, or industrial?
- Are any products supplied to aerospace, defense, medical device, or utility sectors?
- What are approximate annual revenues and the percentage derived from domestic versus export sales?
- Does the operation involve high-voltage testing or significant electrical hazard work on the production floor?
- Has the business experienced any product liability or product recall claims in the past several years?
- Are there any OEM supply agreements that impose specific insurance or indemnification requirements?
- For All Other Miscellaneous Electrical Equipment and Component Manufacturing, what should the underwriter know about products supplied to safety-critical end uses such as aerospace, medical devices, or utility infrastructure?
- For All Other Miscellaneous Electrical Equipment and Component Manufacturing, what should the underwriter know about prior product liability losses with fire, shock, or equipment-damage allegations?
