Tungsten Ore Concentrate
Tungsten ore concentrate is a refined form of wolframite or scheelite ore processed to increase tungsten trioxide content, classified under HTS 2617.90.0060 as 'other' non-ferrous metal ores and concentrates excluding specific listed types. It is primarily used in the production of tungsten carbide tools and alloys.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If roasted or calcined
Roasted molybdenum ores fall under 2613; similar processing on tungsten ore shifts it from unprocessed 'other ores' in 2617.
If containing metals and used for extraction
Processed residues or slags from ore processing used industrially for metal recovery classify under Chapter 26 heading 2620, not raw ores.
If further refined into tungstates
Chemical compounds like sodium tungstate derived from ore are salts of metallic oxides, moving to Chapter 28 from raw ore concentrates.

Import Tips & Compliance
• Verify assay certificate showing tungsten content for accurate quantity reporting per statistical notes, without deductions
• Ensure documentation includes origin certification as many tungsten ores face restrictions or quotas from conflict regions
• Avoid misclassification as slag; confirm it's raw ore concentrate, not industrial residues
