The U.S. International Trade Commission (ITC) has posted the Preliminary Edition of the 2017 Harmonized Tariff Schedule of the United States (HTS or HTSUS; Publication 4659), which was effective on January 1, 2017. The HTS is available as a single full document download or chapter-by-chapter. The 2017 Edition includes a Change Record which shows all the legal and statistical changes that have become effective since January 1, 2016, other than previously proclaimed reductions in staged rates of duty which take effect on January 1, 2017, and non-substantive adjustments to the format of any page. See the Preface to the tariff schedule for additional information and citations for the Presidential Proclamations.

The “Compiler’s Note,” which appears after the “Additional U.S. Rules of Interpretation” explains why the FTA Rules of Origin headings and subheadings in the General Notes may differ from the current HTS heading or subheading.
