On December 29, 2011, President Obama signedProclamation 8771 which amends the Harmonized Tariff Schedule of the United States (HTSUS) pursuant to the World Customs Organization (WCO) recommendations. While the changes became effective internationally on January 1, 2012, they will become effective in the U.S. on February 3, 2012.
WCO's recommendations include changes to 54 different Harmonized Tariff Schedule (HTS) chapters. According to the WCO press release, the 2012 version of the Harmonized Schedule (HS) includes a total of 220 sets of amendments: 98 relating to the agricultural sector; 27 to the chemical sector; 9 to the paper sector; 14 to the textile sector; 5 to the base metal sector; 30 to the machinery sector; and an additional 37 that apply to a variety of other sectors.
The U.S. International Trade Commission (USITC) has posted on its website the updated, preliminary version of the 2012 HTSUS. This version will not be available in printed format.
