[Human-readable page](https://spot.insure/industries/defense) # Insurance Buying Guide for Defense Businesses [Industrials](https://spot.insure/industries/industrials) Before pricing a federal prime contract or accepting a subcontract, separate the prototype or test-unit build and delivery from site integration, acceptance, and any later support. Give the broker a crosswalk of contract party, clause or flow-down, work stage, requested terms, worker/site duties, and who owns each item; ask the contracting officer which federal clauses apply to this award. [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ## Which Insurance Should You Consider? Consider general liability, product liability, commercial property, workers’ compensation, commercial auto, and cyber liability. Start with the coverages tied to your day-to-day operations, then use the situations and buying questions below to compare your options. ### [General liability](https://spot.insure/coverage/general-liability) **When it matters:** A prime clause or subcontract flow-down asks for bodily-injury liability during prototype testing, site integration, or post-acceptance support. [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **What to review:** Federal terms depend on the actual clause and context. Compare the requested limits with CGL wording for the prototype test, site integration, or post-acceptance support named in the contract. [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **Ask:** Are we quoting as prime or subcontractor, which stage does the clause address, and do the proposed terms describe our test, integration, and continuing site work? [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ### [Product liability](https://spot.insure/coverage/product-liability) **When it matters:** You deliver a prototype or completed system, or finish integration, and the contract leaves you responsible for the product or work after acceptance. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **What to review:** CGL products and completed-operations terms can address bodily injury or property damage. Compare the delivered item, integration work, acceptance point, and exclusions in the proposed wording. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **Ask:** Which product, integration activity, customer use, and post-acceptance duty are described, and what exclusions or limits apply? [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ### [Commercial property](https://spot.insure/coverage/commercial-property) **When it matters:** A prototype or test unit remains at your lab, moves to a customer site, or is held alongside customer- or government-furnished property. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **What to review:** Commercial property terms can distinguish business property from property of others and depend on listed locations, values, causes, and exclusions. Do not assume another party’s property is treated the same as your own. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **Ask:** For each build, test, and site stage, who owns or holds the item, where is it, what value should be listed, and how does the proposed form describe it? [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ### [Workers’ compensation](https://spot.insure/coverage/workers-compensation) **When it matters:** You hire employees or subcontractors for prototype testing, installation, integration, or continuing work at a federal or customer site. [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2) **What to review:** Federal contract workers-compensation terms are clause- and context-specific. Identify the actual clause, worker status, work states, and any applicable statutory exceptions before comparing the proposed terms. [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2) **Ask:** Which clause applies to our prime or subcontract role, who performs each site task, and what states, classifications, and employers-liability limits appear in the quote? [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2) ### [Commercial auto](https://spot.insure/coverage/commercial-auto) **When it matters:** Employees drive company, hired, or non-owned vehicles to deliver test units or perform contract-site integration and support. [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **What to review:** Check whether the actual contract clause specifies auto liability in light of vehicle use for performance. Compare the requested terms with the vehicles, drivers, routes, and site tasks in your work plan. [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **Ask:** Does the clause apply to our vehicle use, and does the quote list the vehicles and drivers used for delivery, testing, or field support? [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ### [Cyber liability](https://spot.insure/coverage/cyber) **When it matters:** Prototype integration or continuing support involves contract data, connected equipment, or remote access to customer systems. [Cybersecurity](https://content.naic.org/cipr_topics/topic_cybersecurity.htm), [Cyber Insurance: Cybersecurity for Small Business](https://content.naic.org/sites/default/files/inline-files/cyber-insurance-naic.pdf) **What to review:** Cyber terms vary by proposal, and commercial-property or CGL wording may not address cyber risks. Compare any cyber proposal against the systems and contract work you actually handle; do not treat this as confirmation of federal-program eligibility. [Cybersecurity](https://content.naic.org/cipr_topics/topic_cybersecurity.htm), [Cyber Insurance: Cybersecurity for Small Business](https://content.naic.org/sites/default/files/inline-files/cyber-insurance-naic.pdf) **Ask:** Which company systems, contract data, and vendors are in scope, and how do the proposed terms address incident costs, third-party claims, defense, and exclusions? [Cybersecurity](https://content.naic.org/cipr_topics/topic_cybersecurity.htm), [Cyber Insurance: Cybersecurity for Small Business](https://content.naic.org/sites/default/files/inline-files/cyber-insurance-naic.pdf) ## Need Help Choosing Coverage? Spot prepares your applications, coordinates with brokers, and helps you compare quotes so you can choose coverage with the key details in front of you. [Book a Free Consultation](https://cal.com/team/spotinsure/insurance-consultation) ## Compare the Prime Clause with the Work Before pricing, identify the contracting entity, the prime clause or subcontract flow-down, the requested limit, and the stage it describes: prototype build, test-unit delivery, site integration, acceptance, or continued support. Federal insurance provisions are conditional on the applicable contract context; ask the contracting officer which provisions apply to this award. [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2) Send that clause with the statement of work. Keep prototype delivery and post-acceptance site duties on separate quote rows so the broker can compare each requested term with the activity and proposed form. [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ## Track the Unit, Owner, and Site Handoff For a test unit built in your lab, record who owns it during testing, who takes custody at delivery, and whether your team returns for integration or support after acceptance. List customer- or government-furnished items separately with their locations and values. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) For each stage, give the broker the site, worker and vehicle roles, property owner, contract party, and requested term. Ask which proposed wording matches that stage and flag differences between the prime clause and subcontract flow-down. [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ## Providers to Compare by Coverage These providers document the coverage listed below.

No. FAR 28.307-2 describes conditional contract provisions whose application depends on the contract context and work, including vehicle use for auto terms. Check the clauses in the actual solicitation and award. [28.307-2 Liability](https://www.acquisition.gov/far/28.307-2) [Read the full answer](https://spot.insure/industries/defense/does-far-set-one-package-for-defense-contractors) ### How should a prime and subcontractor prepare a quote for prototype delivery followed by site integration? Show the delivery and integration stages separately. Identify each contract party, clause or flow-down, property owner, requested limit, and continuing duty so the broker can compare the actual work with proposed terms.
