This dataset includes the applicable tariff rates and statistical categories for all merchandise imported into the United States. It is based on the international Harmonized System, the global system of nomenclature that is used to describe most world trade in goods. Although the USITC publishes and maintains the HTSA in its various forms, Customs and Border Protection is the only agency that can provide legally binding advice or rulings on classification of imports. Contact your nearest Customs office with questions about how potential imports should be classified. For a binding ruling on classification, contact the Bureau of Customs and Border Protection. Content The csv is a somewhat condensed version of a series of pdf documents. The row by row contents are generally comprehensive, but the pdf chapters often contain general information that is not included here. Acknowledgements This dataset was made available by [the United States International Trade Commission][1]. You can find the original dataset, updated regularly, [here][2].
