Analysis
HTS 2529.30.00 covers leucite; nepheline and nepheline syenite under heading 2529 (feldspar; leucite, nepheline and nepheline syenite; fluorspar). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in metric tons.
For statistics it divides in two: 2529.30.00.10 for nepheline syenite and 2529.30.00.50 for other. Both pay the same duty; the suffix records which kind was imported.
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 lines in the same group are 2529.10.00 (feldspar; leucite, nepheline and nepheline syenite…, duty-free), 2529.21.00 (containing by weight 97 percent or less of calcium fluoride, duty-free) and 2529.22.00 (containing by weight more than 97 percent of calcium…, 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. That concordance is how imports of this line are compared with US output.
