>90% of food/beverage is domestically produced = no tariffs

That's not true, even for items which undergo relatively little processing like milk:

1. Cows need feed, and in the US this is mostly corn. This corn is mechanically harvested, shucked, and transported.

2. Cows are milked by machine.

3. This milk is then transported to a larger processing facility where it gets filtered, clarified (fat removal for 2%, skim, etc), pasteurized, homogenized (fat is evenly dispersed), and bottled in a blown plastic jug.

4. After bottling, the milk gets palletized and trucked to grocery distribution centers, which will re-palletize it for shipment to individual stores.

At every step of the way, we use machines that require frequent maintenance and whose supply chains rely extensively on imported parts. On-shoring all of this would be expensive and risky both because Trump flip-flops so often and because our next administration may just reverse the tariffs.
