Port of Arrival Immediate Release and Enforcement Determination. A U.S. Customs program that allows entry documentation for an import shipment to be filed at one location, usually an inland city, while the merchandise is cleared by Customs at the port of entry, normally a seaport. May be ineffective with certain types of high-risk cargoes, such as quota-regulated textiles or shipments from drug-production regions. Cities where there is a natural flow of cargo are actually "paired" in the program; e.g., Atlanta, an inland city, is linked with Savannah, a seaport. Tested in '87-'88, it became generally available in mid- '88.
