USITC Tariff Database-Interactive (data current through January 1, 2009) Quick lookup; effective dates; related trade data.

This database is expressed in terms of the 2009 Harmonized Tariff Schedule of the United States (HTS). Tariffs are provided at the tariff-line (8-digit HTS item) level. Where differing units of quantity exist at 10-digit HTS line-item levels for a given 8-digit number, "NA" will appear for quantity. Also, multiple lines of data will appear for those items that changed rates or special-program eligibility during the year.
