Every five years, the World Customs Organization makes changes to the global Harmonized Tariff Schedule (HTS). The U.S., as a contracting party to the convention, is obligated to amend its HTS to reflect the changes. Currently, the U.S. International Trade Commission has posted the preliminary 2012 HTSUS on its website, available at: http://www.usitc.gov/tata/hts/index.htm.
