Analysis
HTS 7318.15.50 covers other screws and bolts, whether or not with their nuts or washers: studs under heading 7318 (screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter pins, washers…). US Customs collects import statistics for it under 4 ten-digit suffixes, reported in kilograms.
Neighbouring lines carry rates from duty-free to 8.5%, so the exact line matters. The widest gap is with 7318.15.80 (having shanks or threads with a diameter of 6 mm or more), at 8.5%: a product that belongs there but is entered here, or the reverse, changes the duty by 8.5 percentage points.
Goods from countries without normal trade relations pay the column 2 rate of 45% instead of nothing, so origin decides between free entry and a 45% duty.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 77% of the 250 tariff lines in chapter 73. Duty-free at the general rate does not rule out additional duties under Chapter 99, such as Section 301 or Section 232 measures, which depend on the country of origin.
