"What it costs now" - "What it cost in March" = "Tariff cost"
The math is not perfect, but to a good approximation (certainly a far better approximation than the administration's insane computation of international "tariffs") that will indicate the cost to the consumer of Trump's tariff policies.
So yes, if the importer eats a significant chunk of the tariff cost and doesn't pass it on to Amazon/the consumer, the computation will reflect that (as it should). And if they don't, it will reflect that too (as it should).
Chaotic: one might disagree on the magnitude of flip-flopping that can be labelled "chaotic", but the unpredictable on-again, off-again nature of the policies is well-described by "chaotic" I think.
Ill-conceived: if you can find me one serious economist who agrees with the Trump tariff policy (i.e. agrees on the goal, the means and the ends, and the match between them), I'll consider retracting this. Otherwise, yep, ill-conceived describes imposing tariffs without any apparent understanding of how they work or their likely effects.
