The Trump administration plans to implement 25% tariffs on aluminum and steel. The craft beer industry could be hit particularly hard by the tariffs.

Canada supplies roughly 60% to 70% of the imports that come into the U.S. market. Canadian suppliers like Rio Tinto produce high quality aluminum that is typically sold to stateside buyers.

The European Union estimates that the first wave of Donald Trump’s steel and aluminum tariffs will hit as much as €28 billion ($29.3 billion) of the bloc’s exports in what would be a massive escalation in the US president’s trade war.
