Check the duty on a customs entry you have already filed, against the tariff schedule as it stood on that line’s own entry date.

What does this code pay?

Type the code and the origin. You get what the schedule required on that line — read at the entry’s own month, with the Chapter 99 arithmetic shown — and what US importers were actually charged on it at the border. Where the rule cannot be settled from the public record, the page says so and names why.

What this cannot tell you

The paid figure is a national average across every importer on that code and origin. Your own line can lawfully sit well away from it and still be right — an exclusion claimed, USMCA content, a quota line, goods returned under Chapter 98, a first-sale valuation. That is the whole reason the difference above is a difference and not a finding.

And a difference is not money owed. We pre-registered the test of whether this gap predicts recoverable duty and it failed — the result is on /limits, in full, with the sort that beat it.
