Copper shipments into the United States are expected to accelerate in the coming weeks in a final scramble to get metal across the border before U.S. President Donald Trump's higher than expected 50% tariff on imported copper takes effect.

U.S. President Donald Trump's announcement of a proposed 50% tariff on copper imports has raised concerns in Chile and Peru, which together account for nearly 40% of global copper production.
