Analysis
HTS 2530.90.80 covers other: other under heading 2530 (mineral substances not elsewhere specified or included). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in kilograms.
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.
Neighbouring lines carry rates from duty-free to 2.9%, so the exact line matters. The widest gap is with 2530.90.20 (natural micaceous iron oxides), at 2.9%: a product that belongs there but is entered here, or the reverse, changes the duty by 2.9 percentage points.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 91% of the 78 tariff lines in chapter 25. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
