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.

Lines actually measured
19,850,923 — each one a code × origin × month of what was charged at the border

Why two numbers and not one
Everyone publishes a rate. The useful thing is the difference between what the rules required and what was actually charged — and the honest naming of the part nobody can settle from public records.
