US Import Duty Rates, Tariff Information & Duty Calculation Explained

Import duty in the United States refers to the taxes imposed on goods imported into the country. The primary purpose of import duty is to protect domestic industries and raise revenue for the government. Importers are required to pay these duties to U.S. Customs and Border Protection (CBP) before their goods are released into the market. The amount of duty payable varies by product and is determined based on the type of goods being imported, their value, and their country of origin.

The calculation of import duty in the United States can be either ad valorem or specific. Ad valorem duties are calculated as a percentage of the goods' value, while specific duties are calculated based on the weight, quantity, or other units of measurement. For example, a good with a value of USD 1000 may be subject to an ad valorem duty of 5%, resulting in a duty of USD 50. On the other hand, a specific duty may be imposed as a fixed amount per unit, such as USD 5 per kilogram.

The Harmonized System (HS) codes play a crucial role in determining the amount of import duty payable. HS codes are used to classify goods and determine their tariff classification. Each HS code corresponds to a specific tariff rate, which is used to calculate the duty payable. Importers must ensure that their goods are correctly classified using the HS codes to avoid incorrect duty payments. Failure to do so may result in penalties and delays in the clearance process.

The country of origin of the goods being imported can significantly impact the amount of duty payable. Goods originating from countries with which the United States has a free trade agreement (FTA) may be eligible for reduced or 0% duty rates. For example, goods from countries such as Canada or Mexico may be eligible for preferential treatment under the United States-Mexico-Canada Agreement (USMCA). Importers must ensure that their goods meet the rules of origin requirements to qualify for these preferential rates.

To calculate the import duty, importers must follow these steps: determine the HS code for the goods being imported, determine the value of the goods, determine the duty rate applicable to the goods, and calculate the duty payable. For example, if an importer is importing goods with a value of USD 1000 and an ad valorem duty rate of 5% applies, the duty payable would be USD 50. Additionally, importers must also consider other costs such as sales tax and other fees associated with the importation process.
