What is a specific duty typically based on?

A specific duty is typically based on the weight or quantity of goods imported. This type of duty is characterized by a fixed amount that is charged per unit, such as per kilogram or per item, making it straightforward to calculate. For instance, if a specific duty is set at a certain dollar amount per kilogram, the total duty owed would be the fixed amount multiplied by the total weight of the imported goods. This approach helps simplify the duty calculation process and allows for more predictable revenue collection for customs authorities.

Other methods of assessing duties, such as ad valorem duties, which are calculated based on the value of the goods, are not categorized as specific duties. This distinction is crucial because it influences how import costs are determined and can affect pricing and market strategies for businesses involved in international trade.
