Antidumping and countervailing duties (AD/CVD) are not tariffs and are not in the Tariff Schedule. Although the ITC has a role in AD or CVD investigations, the rates of duty are set by the International Trade Administration (ITA) of the Department of Commerce.
CBP maintains a public database of many (but not all) instructions implementing the orders at:
These instructions contain information on rates of duty. They also have contact information at the ITA for further information. Questions about the scope of AD/CVD orders should be referred to the contacts in the instructions or to “Contact Import Administration” at: http://www.ita.doc.gov/ia/index.asp
The two sites linked below can be used to find the Department of Commerce case number, which can be used when searching the CBP instruction site linked above.
