Late last week, the US finally agreed to lift all tariffs it had
previously imposed, under section 232 of the Trade Expansion
Act 1962, on steel and aluminum imports from Canada. The
US tariffs, purportedly imposed for national security reasons, had
been a major obstacle to Mexico's and Canada's ratification
of the CUSMA modernization of NAFTA. Canada, accordingly,
agreed to end the tariffs it had imposed in retaliation against the
US tariffs.
Canada secured a considerable victory by seeing the complete
removal of the section 232 tariffs without having to maintain any
residual quotas or restrictions on its exports. This
contrasts heavily with the bargain struck early in the process by
South Korea, which saw a quota at levels which were actually below
then current export volumes.
