Analysis
HTS 7318.16.00 covers threaded articles: nuts under heading 7318 (screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter pins, washers…). US Customs collects import statistics for it under 5 ten-digit suffixes, reported in kilograms.
Rates on the nearby lines range from duty-free to 12.5%. The costliest confusion would be with 7318.12.00 (threaded articles: other wood screws) at 12.5%, a difference of 12.5 points on the customs value.
This line's footnotes point to one additional provision in Chapter 99: 9903.90.09 (measures on products of Russia). Chapter 99 duties are added on top of the general rate for goods of the countries they name, and they change more often than the rest of the schedule, so check the current CBP guidance before you rely on a total.
There is no general-rate duty on this line, which puts it with roughly 77% of the 250 tariff lines in chapter 73 that are also free. 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.
