This page provides a link to studies or proposed modifications to the Harmonized Tariff Schedule to simplify the hierarchy and structure within the existing framework of the 6-digit code that defines the Harmonized System. Proposals include, where possible, collapsing of 8-digit line items or groupings that have the same rates, or removal and collapsing of 10-digit statistical breakouts that are no longer needed.

In response to a request by the committee on Ways and Means of the United States House of Representatives and to the Committee on Finance of the United States Senate, the USITC has developed a draft simplification of the Harmonized Tariff Schedule of the United States (HTS).  The report of that investigation (Investigation No. 332-388) was transmitted to the Committees on June 30, 2000.  To make the report as accessible as possible this report is available for viewing or downloading, either in its full form (first link below) or as individual chapter files (second and third links below).
