摘　　要：美国是世界上钽的主要消费国，在钽产业链中处于最顶端，其进出口形势在一定程度上可以反映出世界钽业的发展情况。本文分析了2003～2012年美国钽矿产品的进出口量和进出口额的变化情况，总结了美国的钽矿砂及其精矿对外依存度居高不下、钽矿砂及其精矿以及钽废料的进口量最大、进口来源地日趋多元化、中国成为美国最大的进口来源地等特征，并对其以后的进口形势以及为保障供应而可能采取的措施进行了预判。As a major consumer of world tantalum, the United States is in the top of the global tantalum industry value chain, so its tantalum import and export situation can reflect the development of tantalum industry to a certain degree. This paper analyzes the quantity and volume changes of tantalum summarizes some features as follows： all of American tantalum ore port and export between 2003 and 2012, and and concentrate need to be imported; the import valumes of tantalum ore and concentrate as well as tantalum waste and scrap are the highest; the import source is increasingly diversified; and China has become the largest import source of America. Finally, the trend of import and some possible measures to be taken by America for guaranteeing tantalum supply are predicted.
