2529.10.00

Analysis

HTS 2529.10.00 covers feldspar; leucite, nepheline and nepheline syenite; fluorspar: feldspar under heading 2529 (feldspar; leucite, nepheline and nepheline syenite; fluorspar).

There is no general-rate duty on this line, which puts it with roughly 91% of the 78 tariff lines in chapter 25 that are also free. 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 2529.21.00 (containing by weight 97 percent or less of calcium fluoride, duty-free), 2529.22.00 (containing by weight more than 97 percent of calcium…, duty-free) and 2529.30.00 (leucite; nepheline and nepheline syenite, duty-free).

Census statistics map these goods to NAICS 21232 (Sand, Gravel, Clay, and Ceramic and Refractory Minerals Mining and Quarrying), an industry of 2,617 US establishments employing 36,740 people, the industry a domestic producer of these goods reports under.

All 3 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.

The general rate of Free has not changed in any edition of the schedule since Jan 2023.
