Analysis
HTS 2615.90.60 covers other: other under heading 2615 (niobium (columbium), tantalum, vanadium or zirconium ores and concentrates). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in kilograms.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 97% of the 39 tariff lines in chapter 26. 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 2615.10.00 (zirconium ores and concentrates, duty-free) and 2615.90.30 (synthetic tantalum-niobium (columbium) concentrates, duty-free).
Census statistics map these goods to NAICS 21229 (Other Metal Ore Mining), an industry of 58 US establishments employing 3,719 people. That is the industry code a US manufacturer of the same product would normally use.
The ten-digit suffixes separate niobium, tantalum ores and concentrates and vanadium ores and concentrates. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.
