There must be a mind boggling amount of profit going to these importers to get basically all of the tariff proceeds back on already completed transaction with zero expectation that it be paid back to the people bearing the cost.

I can't imagine their margins are usually very high, the tariff rates are astronomical compared to their usual margins. Hopefully someone here has more information than me because to my naive mind this basically absolutely explodes the free cash reserves of importers from high volume high tariff countries creating a lottery winnings for a business sector of epic proportions rarely seen.
