Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for crude wolframite ore
Unconcentrated ores are classified separately from beneficiated concentrates.
If further processed into ammonium paratungstate (APT)
Chemical compounds like APT move to Chapter 28 for inorganic chemicals.
If ferro-tungsten alloy produced
Ferroalloys containing tungsten classify under Chapter 72 iron/steel.

Import Tips & Compliance
• Declare exact assay quantity of tungsten content per statistical note requirements
• Comply with REACH or TSCA for trace heavy metals common in wolframite
• Use ISRT codes for accurate trade statistics on tungsten concentrates

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.
High-Grade Ferberite Tungsten Concentrate
Premium concentrate from ferberite (FeWO4), enriched to over 70% WO3 via multi-stage flotation. HTS 2611.00.60.00 covers such beneficiated tungsten concentrates used in electronics and aerospace applications.
Recycled Tungsten Ore Concentrate
Concentrate recovered from mining tailings or recycled scheelite/wolframite, processed to 55-65% WO3. Qualifies under HTS 2611.00.60.00 as tungsten concentrates regardless of secondary origin.
APT-Feed Tungsten Concentrate
Purified concentrate specifically prepared as feedstock for ammonium paratungstate (APT) production, with low silica/phosphorus impurities. HTS 2611.00.60.00 applies to all tungsten concentrates including those for chemical processing.
