美国总统唐纳德·特朗普(Donald Trump)周三签署了一项公告，将从8月1日起对铜征收50%的关税。
“该公告对半成品铜产品(如铜管、线材、棒材、板材和管材)和铜密集型衍生产品(如管件、电缆、连接器和电气元件)的进口征收普遍50%的关税，自8月1日起生效，”据白宫称。
特朗普此前宣布这一关税将生效，但随着这一公告的签署，这一关税于周三正式生效。
Trump to impose 50% copper tariff effective Aug. 1
President Donald Trump signed a proclamation on Wednesday to put a 50% tariff on copper into effect on Aug. 1.
"The Proclamation imposes universal 50% tariffs on imports of semi-finished copper products (such as copper pipes, wires, rods, sheets, and tubes) and copper-intensive derivative products (such as pipe fittings, cables, connectors, and electrical components), effective August 1," according to the White House.
Trump previously announced this tariff would go into effect, but made it official on Wednesday with the signing of this proclamation.
