Implementation of the World Customs Organization (WCO) amendments to the 2007 HTSUS (outlined below) will likely be delayed until later in January or until February 2007. The President cannot proclaim the implementation of these amendments until a required 60 legislative day Congressional layover period is completed, and the amendments can not go into effect for at least 15 days after the Presidential proclamation is published in the Federal Register.
According to the information on the ITC website, effective January 1, 2007 there will be an electronic version of the 2007 HTSUS posted on that website, but this will not include the WCO amendments. Once the amendments are incorporated into the 2007 HTSUS, the revised version will be published on the ITC website and the Government Printing Office will publish a hard-copy version of the 2007 HTSUS.
