The ISF importer can elect to use different ISF agents for each separate filing. Also, those ISF agents may use either vessel ACE or ABI to do these separate filings. However, if a unified entry filing is being done, ABI must be used and the ISF importer must self-file (less than 12 per year) or use a licensed U.S. customs broker to do the filing on his behalf.
