Since you mention it... the stupid part about it is it was all political, all about destroying American jobs.
They got fined because they imported the wood (that they bought legally but some government tool claimed some obscure paperwork was not filed in a foreign country) and had American workers get paid to finish it.
Had they imported the same wood, but chose to have some foreign workers do all the work like the rest of the Communist supporting big evil corporations, ahead of time and just import it all finished so no US workers got any jobs... No problem at all.
Just goes to show, totally messed up political BS from our government.
