@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.
Additional Named Insured. Additional Named Insureds are considered to be owners of the policy. Therefore an Additional Named Insured has full access to the coverage provided by the policy with very few (if any) restrictions. However, the rights afforded to Additional Named Insureds come with risks.
As for the types of policies a landlord might require to be listed as an additional insured, it is common and reasonable for a landlord to be listed as an additional insured on commercial general liability, automobile, and umbrella policies.
