Duty rates

General
Free
The base rate for goods from most countries.
Special
—
Lower rates under trade agreements and programs, for goods that meet their rules of origin; each symbol names one.
Column 2
35%
The higher rate for the few countries without normal trade relations with the United States.

These are base rates, not what you pay. The country of origin can add extra duties (Sections 301, 232 and others), and customs fees come on top: the calculator adds up what applies to your goods, each with its source. Why the base rate is not enough

Being listed is not owing a duty. A note may list goods that a measure leaves out; whether a heading applies depends on the origin, the date and the product; and the measures on all the goods of a country list no code at all. The calculator says what applies.
