FIGURE 1: Location of the Top 25 U.S. International Freight Gateways Ranked by Shipment Value: 2003

Notes: All data-Trade levels reflect the mode of transportation as a shipment enters or exits a U.S. Customs port. Flows through individual ports are based on reported data collected from U.S. trade documents. Low-value shipments (imports less that $1,250 and exports less than $2,500) and intransit shipments are not included in trade data. Air-Data for all airports are based on U.S. port classifications and include a low level (generally less than 2% to 3% of the total value) of small user-fee airports located in the same region. Air gateways not identified by airport name include major airports in that geographic area in addition to small regional airports. Also due to U.S. Census Bureau confidentiality regulations, data for some of the air gateways include courier operations. For example, data for New Orleans Custom Port's international air cargo include FedEx air cargo activity in Memphis, TN.
