Data Series
Exports
Origin of Movement - Based on Origin State: In 1985, a new field indicating the state where the export journey begins was added to export reporting requirements. This field allowed the compilation of the State of Origin of Movement (OM) Series. The OM series based on origin state, that became available in 1987, provides export statistics based on the state from which the merchandise starts its journey to the port of export; that is, the data reflect the transportation origin of exports.
Origin of Movement - ZIP Code Based: In 2004 the ZIP Code of the USPPI, the party in the United States that receives the primary benefit monetary or otherwise from the shipment, was redefined to indicate the origin of movement of goods. Initially it did not necessarily represent the location of the USPPI. However, due to increased electronic reporting in the AES, the validity of the reported ZIP Code has improved significantly since 2004.
Note: Effective with January 2006 statistics, a new OM State series - based on ZIP Code, is available on our website.
Imports
State of Destination (SD) Series: Also in the mid 1980s state data based on the import state of destination were added. However, in 1988, release of the data on import state of destination was discontinued due to quality concerns. Since then changes to the import reporting requirements along with growth of electronic reporting and a better understanding of the data’s limitations has made it possible to bring back the import state of destination series.
Effective with January 2010 statistics, this new SD series will be available. A new supplement will be added to the FT900: U.S. International Trade in Goods and Services. In addition the following data products will be produced: Import state data by 6-digit Harmonized System (HS) and Import state data 4-digit North American Industry Classification System (NAICS). An example of the data structure for these files can be found on our website. Historical data tables and products will be made available for monthly data back to January 2008.
This new series is based upon the U.S. State of Destination Code. This is defined as the U.S. state, U.S. territory or U.S. possession where the merchandise is destined, as known at the time of entry summary filing. If the contents of the shipment are destined to more than one state, territory, or possession, or if the entry summary represents a consolidated shipment, report the state of destination with the greatest aggregate value. If in either case, this information is unknown, the state of the ultimate consignee, or the state where the entry is filed, in that order, should be reported. However, before either of these alternatives is used, a good faith effort should be made by the entry filer to ascertain the state where the imported merchandise will be delivered. In all cases, the state code reported should be derived from the standard postal two-letter state or territory abbreviation. For shipments into FTZ’s, the import state represents the location of the zone.
