Chalcopyrite-Sphalerite Mixed Concentrate
Mixed mineral concentrate of chalcopyrite (copper iron sulfide) and sphalerite (zinc sulfide) from bulk flotation. HTS 2603.00.00.30 applies due to zinc content in copper ore hierarchy, with assay-based reporting. Critical input for copper smelters handling impurities.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If negligible zinc content
Pure copper content without significant zinc falls under copper-only subheading.
If tungsten-bearing copper ores
Tungsten content directs to tungsten ores even with zinc.
If leached residues with zinc
Hydrometallurgical residues classify under 2620 for metal recovery.

Import Tips & Compliance
• Specify mineralogy (chalcopyrite/sphalerite ratio) in certificates for classification confirmation
• Comply with ISPM 15 for wooden packaging if used in ore transport
• Prepare for penalties if zinc content exceeds declared assay upon inspection
Related Products under HTS 2603.00.00.30
Zinc-Bearing Copper Ore Concentrate
Copper ore concentrate containing significant zinc content, typically extracted from polymetallic deposits where zinc minerals like sphalerite are intermingled with copper sulfides. Classified under HTS 2603.00.00.30 due to its zinc content within the copper ores and concentrates hierarchy, with quantity reported as assay zinc without deductions. Primarily used in smelting processes to recover both copper and zinc.
Polymetallic Copper-Zinc Ore Fines
Fine particles of copper ore with substantial zinc impurities, often resulting from crushing operations in polymetallic mines. Falls under HTS 2603.00.00.30 for its zinc content within copper ores, adhering to statistical notes on metal assay quantities. Utilized in flotation processes to separate copper and zinc sulfides.
High-Zinc Copper Sulfide Concentrate
Flotation concentrate from copper sulfide ores with elevated zinc sulfide (sphalerite) levels, common in porphyry copper deposits. HTS 2603.00.00.30 captures its zinc content under copper concentrates, with reporting based on undeducted assay quantities. Essential for pyrometallurgical recovery of base metals.
Secondary Copper Ore with Zinc Impurities
Recovered copper ore from tailings or waste dumps containing residual zinc, reprocessed for economic recovery. Classified in HTS 2603.00.00.30 for zinc content in copper ores, following statistical notes on metal quantities. Used in secondary metallurgy circuits.
