The Harmonized Tariff Schedule of the United States (HTS) is the primary resource for determining tariff classifications for goods imported into the United States. The U.S. Harmonized Tariff Schedule, classifies a good (assigns it a ten-digit tariff classification number) based on such things as its name, use, and/or the material used in its construction. The tariff schedule is divided into Chapters 1 through 99 plus numerous additional sections such as various appendices and indexes. Chapters are divided into a varying number of headings, and headings are divided into a varying number of subheadings. Raw materials or basic substances often appear in the early chapters and in earlier headings within a chapter, where highly processed goods and manufactured articles often appear in later chapters and headings. Agricultural products are generally provided for in chapters 1-24, for example, whereas vehicles, aircraft and vessels appear in chapters 86-89. There is no hard and fast rule, however. Toys, for example, appear in Chapter 95 and works of art are found in Chapter 97. You will need to know all of this for the upcoming exam!
