I plainly said in another reply that US damage is much less certain than I had originally anticipated.
What your link says is that WI has $1.4B in total exports to China that could potentially come under retaliatory tariffs. (which is about 6% of Wisconsin exports) Who will ultimately pay those export tariffs if indeed they are all enacted is unknown at this point. And whether those exports will be reduced or to what extent is uncertain. I begin this by saying that certain Chinese export vendors were all willing to absorb 100% of US tariffs, which was surprising to me. So the often touted statement that "tariffs are just a tax on US the consumer" isn't true in those cases. Maybe Chinese importers are just going to pay the Chinese tariffs too, I have no idea. I did call China, and as of right now you can still buy cheese there, so apparently WI whey is still shipping.
I see Trudeau just imposed a 25% tariff on Chinese steel yesterday, so Canada has jumped on the anti-Chinese steel dumping bandwagon.
