This past week, antidumping and countervailing duties imposed by the US International Trade Commission on imported Chinese aluminum extrusions took effect. These duties total at least 40% tacked on to the costs of all aluminum extrusions imported to the US from China, and will remain in effect for 5 years – until May, 2016. Outside of the trade press, this hasn’t made much more than a ripple – particularly in the mainstream media. You’d think this event would’ve been the Bin Laden story that US manufacturing has been waiting for for 10 years. Oh, it was covered alright … but we just haven’t heard this story trumpeted with the same volume and vigor that tire tariffs got. This is a big deal, for many reasons. And it raises some interesting points beyond the obvious benefits to US manufacturing.
