Analysis
HTS 2804.50.00 covers hydrogen, rare gases and other nonmetals: boron; tellurium under heading 2804 (hydrogen, rare gases and other nonmetals). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in kilograms.
Neighbouring lines carry rates from duty-free to 5.5%, so the exact line matters. The widest gap is with 2804.69.50 (other: other), at 5.5%: a product that belongs there but is entered here, or the reverse, changes the duty by 5.5 percentage points.
For statistics it divides in two: 2804.50.00.10 for boron and 2804.50.00.20 for tellurium. Both pay the same duty; the suffix records which kind was imported.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 29% of the 274 tariff lines in chapter 28. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
Goods from countries without normal trade relations pay the column 2 rate of 25% instead of nothing, so origin decides between free entry and a 25% duty.
