0240 GMT - Copper and aluminum rise in early Asian trade. President Trump has signed a proclamation adjusting certain metals tariffs to more effectively address national security threats, the White House said. Foreign companies that use more U.S. steel and aluminum can qualify for a 10% duty rate, if their capital equipment includes at least 85% of U.S. melted and poured or smelted and cast steel or aluminum by weight, it said. The premium for copper in the U.S. has also risen again, ANZ Research analysts say in a note. "This could see renewed flows of the metal to U.S. ports just as supply side issues mount in the market," they add. The three-month copper contract on the LME is up 0.3% at $13,877.00 a metric ton, while aluminum is 1.1% higher.(amanda.lee@wsj.com)

A greater range of industrial and agricultural equipment made with the metals will temporarily face a reduced 15% levy starting June 8, per the White House.

Trump has amended tariffs on select metal and equipment imports, offering lower rates and incentives aimed at boosting US manufacturing investment.
