Customs duty

A customs duty is a tariff or tax which a country imposes on goods when they are transported across international borders. Customs Duties are used to protect countries' economies, residents, jobs, and environments, by limiting the flow of imported merchandise, especially restricted and prohibited goods, into the country. The Customs duty rate is a percentage determined by the value of the article purchased in the foreign country and not based on quality, size, or weight. U.S. customs duties are listed in the Harmonized Tariff Schedule of the United States.

September 22, 2025 by Jacob Kopnick|Top News

The U.S. filed its opening brief at the Supreme Court on Sept. 19 in the lead cases on the legality of tariffs imposed under the International Emergency Economic Powers Act. Solicitor General D. John Sauer said the reciprocal tariffs and tariffs on China, Canada and Mexico meant to stop the flow of fentanyl are a valid exercise of IEEPA, adding that the tariffs are a proper expression of presidential policymaking in emergency situations.
