The point is to inflict cost to create incentive for domestic production. Obviously the inconsistency on tariffs undermines this position but the pandemic made it very clear that there are domestic security implications for not having important products produced state side. Its not like the $500 cost of a saline bag has anything to do with its production cost. It seems credit liquidity and confidence in long term protectionism are needed for this scheme to work. This requires unity, which we lack.
