Analysis
Heading 2611 of the Harmonized Tariff Schedule covers tungsten ores and concentrates. It has 2 tariff lines.
Every one of its 2 tariff lines is duty-free at the general rate, so classification within the heading affects statistics and Chapter 99 measures rather than the base duty.
Its lines are 2611.00.30 for tungsten ores and concentrates: ores (duty-free) and 2611.00.60 for tungsten ores and concentrates: concentrates (37.5¢/kg on tungsten content).
1 of the lines carry specific or compound rates (per kilogram, per dozen and so on) rather than a percentage, so their burden depends on the unit value of the goods.
By Census's concordance, most of its statistical lines are made by Other Metal Ore Mining (21229). Those are the NAICS industries a US producer of these goods would report under.
Its median rate of duty-free sits at the 49th percentile of the headings in chapter 26.
