"The ruling was silent on whether tariffs that have been paid under the higher rates will need to be refunded." - from CNBC

This is why I mentioned "litigation" in my comment, i.e. you probably would need to separately sue the government if you want to refund the tariffs.

That's not how it works.

There is a normal process in place for importers/brokers to request refunds if a specific tariff was overpaid or a tariff was ruled to be illegal.

But if you imported through DHL and you were not the broker, that is more complicated, you might need to ask DHL for it, and they might not want to do it for you (as they don't have a standard process in place).
