The Commerce Department’s Bureau of Industry and Security (BIS) has formally launched two Section 232 investigations that could lead to import restrictions on copper and lumber and timber, according to Federal Register notices scheduled for publication on Thursday. Trump signed an executive order on Feb. 25 ordering the copper probe and another on March 1 for lumber and timber. Both instructed Commerce Secretary Howard Lutnick to start the investigations, which threaten to further strain trade relations with Canada and other trading partners. The Section 232 law allows up to 270 days for a probe, but White House officials said they expect Lutnick to move faster. In one sign of that, BIS set an extremely short period for public comment in the two investigations, ending on April 1. that coincides with the deadline for executive branch agencies to compete a number of trade reports for the White House.
