@Jack, In a routed transaction, both must occur. The FPPI must facilitate the export and then authorize the USPPI or a U.S. agent to file the EEI. If the FPPI has not authorized a filer, however, that does not mean it is not a routed transaction.
It is just a proof of insurance. Additional Insured: The main contractor is named as an additional insured on the certificate of insurance and is actually given coverage, and has rights under the sub-contractors or vendor's, the Named Insured policy in the event of a future claim.
Also, it usually does not provide completed operations coverage for the additional insureds, and it may provide. only the amount of coverage the contract requires even if the policy actually provides more. The contractor. must request to add completed operations coverage separately for each additional insured.
