Analysis
HTS 6804.21.00 covers of agglomerated synthetic or natural diamond under heading 6804 (millstones, grindstones, grinding wheels and the like, without frameworks, for grinding…). US Customs collects import statistics for it under 4 ten-digit suffixes, reported in number of items.
This line's footnotes point to one additional provision in Chapter 99: 9903.90.08 (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.
The normal trade relations rate here is zero, shared by about 60% of the 67 tariff lines in chapter 68, a useful check when a neighbouring dutiable line is a candidate. 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.
Goods from countries without normal trade relations pay the column 2 rate of 30% instead of nothing, so origin decides between free entry and a 30% duty.
