I have to assume that some of that 4% has second order negative effects on US importers and consumers.

Profit margins can not always go down by 4% and in those cases goods and services would then not be available to US importers and consumers is only one example.

My assumption is that the 96% statistic does not fully encapsulate the negative costs to consumers. I have to to wonder how much higher the burden is over 96% when all second order effects are taken into account.
