一群美国会议员打算取消个人买家通过跨境电商购买800美金以内的商品的免税政策，请看本报周四的报道：

A bipartisan group of U.S. lawmakers planned to introduce a bill to eliminate a tariff exemption widely used by e-commerce sellers to send orders from China to U.S. shoppers, one of the sponsors said.

The exception, known as the de minimis rule, exempts imports valued at US$800 or less from tariffs if the items are shipped to individual consumers in the United States.

The bill would ban such shipments from China immediately upon enactment, sponsor Republican Senator Bill Cassidy said.

报道中的de minimis rule是个法律常用词，可译为“最低限度规则”，意思是“对于微不足道的事项可以忽略不计的原则”，比如征税有起征额，低于一定数额的交易或者收入可以免税。
