The Concordance files are designed for those who use our published data. 

These files contain:
  • All current export and import commodity codes for which we collect trade data
  • Descriptions Units of quantity
  • Corresponding codes in other classification systems (e.g. End-Use, NAICS, SITC, etc.)

The Concordance files are updated annually in mid-February, when we publish data for the new year.  The import file may change during the year as often as the Harmonized Tariff Schedule of the United States Annotated (HTSUSA) is revised.

The AES Concordance files are designed for those who file export transactions. 

These files include:
  • All current Schedule B codes (AES Export Concordance)
  • All current Harmonized Tariff Schedule (HTS) codes that can be reported for export purposes (AES Import Concordance)
  • Descriptions
  • Required units of quantity

The AES Import Concordance excludes HTS codes that are not valid for AES.  The AES Concordance files are updated annually in late December.
