Analysis
Heading 8101 of the Harmonized Tariff Schedule covers tungsten (wolfram) and articles thereof, including waste and scrap. It divides into 5 six-digit subheadings and 6 eight-digit tariff lines, with 6 ten-digit statistical suffixes below them.
None of its 6 lines is duty-free at the general rate. Rates run from 2.8% to 7% with a median of 5.45%, so the line you choose sets the duty.
Its median rate of 5.45% sits at the 80th percentile of the headings in chapter 81.
The largest subheadings are 8101.99 (other, 2 lines), 8101.10 (unnamed, 1 line), 8101.94 (unnamed, 1 line) and 8101.96 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by Nonferrous Metal (except Copper and Aluminum) Rolling, Drawing, and Extruding (331491), Secondary Smelting, Refining, and Alloying of Nonferrous Metal (except Copper and Aluminum) (331492) and Nonferrous Metal (except Aluminum) Smelting and Refining (331410). Those are the NAICS industries a US producer of these goods would report under.
