Unidentified International Trade

The 'Unidentified' code is assigned when the state of origin for exports or the state of destination for imports is not reported, cannot be determined from available documentation, or is withheld for confidentiality reasons in Census Bureau trade statistics.

Unidentified records should generally be excluded from state-level comparisons and aggregations, as they do not represent a specific geographic trade flow and including them can distort state-by-state trade volume calculations.

Unidentified state records typically represent a small fraction of total U.S. trade data volume, but their presence signals incomplete reporting that may affect the accuracy of origin-destination trade flow analyses.
