Signed agreement
Define the parties, work, insurance duties, lower-tier rules, claims cooperation and remedies.
Product businesses and outsourced work
Subcontractor and vendor insurance for product businesses
Outsourcing manufacturing, assembly, installation, fulfillment or repair does not automatically transfer your liability or protect your balance sheet.
Why the paperwork matters
A certificate is evidence.
It is not the policy.
The agreement, insurance and records should support the protection your business intended to require.
Being listed as a certificate holder does not make your company an additional insured. A checked box on a certificate does not replace the endorsement or policy provision. Names, dates, limits, covered work and conditions should be reviewed before authorization.
Requirements should be selected for the actual work, contract and state. Your attorney should address enforceability and legal remedies; your insurance professional should address the insurance evidence and policy wording.

Industry-specific questions
Map the insurance requirement to the outsourced function
A contract manufacturer may create product liability and recall concerns; an installer adds completed-operations and auto exposures; a designer may need manufacturers E&O; and a logistics vendor can create cargo, warehouse and cyber questions.

- Installers and field-service firms
- Warehouses, fulfillment firms and logistics vendors
- Product designers, testing labs and consultants
- Repair, warranty and recall-response vendors
Questions to resolve

Frequently asked questions
Subcontractor insurance questions
Is a certificate of insurance enough?
No. A certificate summarizes reported insurance but does not create coverage. Review the policy provisions or endorsements supporting additional-insured status, waiver of subrogation and primary wording when those protections are required.
When should subcontractor insurance be checked?
Set the requirements before bidding or work authorization, collect the agreement and insurance evidence before work begins, and monitor renewals and scope changes through the required completed-operations period.
Can an exception be approved?
Management may make a documented business decision, but an internal exception does not change an upstream contract or bind an insurer. Resolve the insurance issue with your agency and obtain legal advice about contractual consequences.
Review the insurance before the work
Need help with a subcontractor requirement?
Send the proposed insurance requirements early so the coverage questions can be identified before an agreement is signed.
