Analysis
HTS 2511.10.50 covers natural barium sulfate (barytes): other under heading 2511 (natural barium sulfate (barytes); natural barium carbonate (witherite), whether or not…).
The general rate is $1.25/t, a specific or compound duty rather than a simple percentage, so the effective burden depends on the unit value of the goods: cheap goods pay proportionally more than expensive ones. Importers usually convert it to an ad valorem equivalent to compare it with other lines.
Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 12 others can enter duty-free instead of paying $1.25/t. It is also eligible under GSP, the developing-country programme, which Congress has to renew; check whether GSP is in force on the entry date.
The other lines in the same group are 2511.10.10 (natural barium sulfate (barytes): ground, duty-free) and 2511.20.00 (natural barium carbonate (witherite), 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.
