Customs duty

A customs duty is a levy imposed on imported or exported goods. This is a form of tax, and is typically calculated based on the value of the goods being imported or exported, or some other measure, such as its weight or cubic volume. A customs duty is usually imposed in order to provide revenue for a government, though it may also be imposed in order to protect a domestic industry from lower-priced goods coming into the country. Customs duties are especially effective when used to counteract predatory pricing on goods being imported from outside the country.
