Scheelite Tungsten Concentrate
A high-grade concentrate derived from scheelite ore (CaWO4), containing approximately 65-70% WO3 after flotation processing. Classified under HTS 2611.00.60.00 as tungsten concentrates, distinct from raw ores in subheading 2611.00.10.00 due to beneficiation increasing metal content.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unbeneficiated or minimally processed
Raw tungsten ores before concentration fall under the ores subheading.
If chemically refined to high purity tungsten
Processed tungsten metal products shift to Chapter 81 for unwrought tungsten.
If containing significant arsenic or used for metal/chemical extraction
Per Chapter 2620 notes, residues with arsenic for extraction classify there.
