Analysis
HTS 2519.90.50 covers other: other under heading 2519 (natural magnesium carbonate (magnesite); fused magnesia; dead-burned (sintered) magnesia…).
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.
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.
The other lines in the same group are 2519.90.10 (fused magnesia and dead-burned (sintered) magnesia, duty-free) and 2519.90.20 (caustic calcined magnesite, duty-free).
Census statistics map these goods to NAICS 327992 (Ground or Treated Mineral and Earth Manufacturing), an industry of 275 US establishments employing 10,279 people. That is the industry code a US manufacturer of the same product would normally use.
