Duty rates
Column 1, General
Not stated at any level above this lineThe rate for goods from countries with normal trade relations.
Column 1, Special
No programme rate on this lineOnly if the goods qualify under that programme's rules of origin, which is a determination nobody here can make for you.
Column 2
Not stated at any level above this lineFor the small number of countries named in General Note 3(b), which is not held here.
Additional duties
No footnote on this line, or on the lines above it, points at a chapter 99 provision.
These are the published rates for this line. They are not a landed duty. Additional duties under chapter 99, which is where section 232 and section 301 sit, can apply through the U.S. notes to that chapter without a footnote on this line, and those notes are not held here. Classification and country of origin are yours to determine.
