Analysis
HTS 2526.10.00 covers not crushed, not powdered under heading 2526 (natural steatite, whether or not roughly trimmed or merely cut, by sawing or otherwise…).
The normal trade relations rate here is zero, shared by about 91% of the 78 tariff lines in chapter 25, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
The other line in the same group is 2526.20.00 (crushed or powdered, duty-free).
Census statistics map these goods to NAICS 21239 (Other Nonmetallic Mineral Mining and Quarrying), an industry of 236 US establishments employing 10,238 people. That concordance is how imports of this line are compared with US output.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
