Some products are named in the Tariff Schedule and can be found by searching for the name. Be aware, however, that finding a name of a product does not guarantee a correct classification. Consider the classification of a kitchen paring knife with a ceramic blade. Either a word search or casual browsing through the Tariff Schedule might lead to heading 8211 ("Knives with cutting blades, serrated or not, . . . ."). However, Chapter 82 Note 1 excludes articles with a blade of ceramic from Chapter 82. The proper classification is in Chapter 69 as an article of ceramics.
A systematic method for classification is described below, using the General Rules of Interpretation (GRI) and Additional U.S. Rules of Interpretation (at the beginning of the Tariff Schedule) and the appropriate legal descriptions and notes in Chapters 1 to 97.
Consider the classification of a purebred dog being imported for breeding. First, find four-digit headings where the product is described. Look for headings in Chapter 1, "Live Animals." [Note that according to GRI 1, some texts in the Tariff Schedule (e.g. chapter titles) are useful to find appropriate headings but have no legal significance.]
At this stage, compare only descriptions at the four digit, "non-indented" heading level, and read the descriptions of each heading until you decide which one covers the imported product most specifically. For example, if you consider heading 0101 ("Live horses, asses, mules and hinnies"), the description "Purebred breeding animals" in subheading 0101.10 only relates to horses, etc. Even if the dog in question is a purebred breeding animal, it cannot be classified anywhere within heading 0101 because it is not described in the non-indented text.
"Dogs" are not mentioned by name in any of the four-digit headings, but are described by the category "other live animals" ( heading 0106); there is no other possible provision in the schedule. This heading is a residual or "basket" category. The meaning of "other in this heading is derived by excluding the things named in all the headings that precede it. [Thus, it is often not possible to describe by a short simple statement what is included within many tariff classification numbers–especially the "baskets."]
If instead a product is described equally closely by more than one four-digit heading, check relevant section and chapter notes for definitions or exclusions that may eliminate some four-digit headings. If necessary, apply GRI's to decide which of the remaining four-digit headings applies.
After choosing a four-digit heading, compare the descriptive texts of that heading that appear at the first level of indentation to find the most specific category. Then compare descriptions at the second level of indentation, and so forth. Again, apply the GRI's as appropriate in deciding between equally specific subheadings. [Six-digit and eight-digit categories are called "subheadings."]
Although, in principle, articles can be classified in only one place, classification often requires interpretation and judgment. U.S. Customs and Border Protection (CBP) has authority to make classification decisions and may disagree with a reasonable classification offered by the importer. Published Customs rulings ((http://rulings.cbp.gov) are often useful to see how Customs looks at the issues. USITC does not issue classification decisions.
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:
http://addcvd.cbp.gov/index.asp?ac=home
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.
