Does Business Interruption Cover Supplier Shutdowns?
Only if contingent business-interruption coverage or another extension applies, and the supplier loss meets its requirements.
Ordinary business-income coverage usually focuses on damage to the insured’s own premises. Contingent business interruption (CBI) can extend protection when a listed supplier or customer suffers qualifying property damage that interrupts your operations. The Insurance Information Institute notes that CBI can be limited to physical damage and may require named supplier locations; a general supply-chain disruption is not automatically covered.
Check whether direct and indirect suppliers are included, whether locations must be scheduled, which causes qualify, and what waiting period and limit apply. Update the schedule when suppliers change. Ask about broader supply-chain cover if the risk involves road closures, labor shortages, or nonphysical disruptions.
