On July 30th, US time, US President Trump signed a proclamation to impose a unified 50% tariff on imported semi-finished copper products and copper-rich derivatives starting from August 1st. The tariff covers semi-finished copper products such as copper pipes & tubes, copper wires, copper billets, copper plates, etc., as well as copper-rich derivatives such as pipe fittings, cables, connectors, electrical components, etc. This news has triggered a strong market reaction.
