> While they have no legal obligation to refund those surcharges they imposed, it would be straightforward to do so and it would be the right thing to do.

I'm actually interested to see how this goes legally. I haven't seen an actual attorney who understands the subject chime in on it yet. But I could see a case being made that a line item like that could have a basis of being refunded if the company charging them itself received a refund. Certainly a long shot, but I'm guessing someone will bring a case at some point to see what happens.

Ironically companies that broke out tariffs charges as line items were lauded for "doing the right thing" and are the only companies who could possibly be remotely on the hook here - any other company simply adding it to general margins is quite obviously in the clear.
