Harmonized Commodity Master Files

The files were created to link trade data to other economic data and with other product or commodity codes. This series is comprised of electronic cross-reference files for Schedule B commodity codes.

The files cross-reference commodity code by end-use code, Standard Industrial Classification based product code, Standard International Trade Classifica tion code, North American Industry Classification System codes, and agricultural or non-agricultural code, and provide commodity descriptions for imports and exports. This data comprises government records extracted from the Archival Research Catalog (ARC). See the ARC catalog entry for this series for more information on this data and how to order it.
