Zinc Blende Ore
Zinc blende, also known as sphalerite, is the primary zinc ore consisting mainly of zinc sulfide (ZnS) with minor impurities. It falls under HTS 2608.00.00 as a zinc ore mined directly from deposits and used for zinc extraction after concentration. This classification covers natural zinc-bearing ores prior to smelting or refining.

Import Tips & Compliance
• Obtain accurate assay reports certifying zinc content to comply with statistical reporting requirements without deductions
• Verify origin certificates as many zinc ores come from major producers like Australia or Peru to qualify for preferential tariffs
• Avoid misclassification as zinc concentrates if ore particles exceed typical concentration thresholds

Willemite Zinc Ore
Willemite is a zinc silicate mineral (Zn₂SiO₄) found in oxidized zinc deposits, often with fluorescent properties. Classified under HTS 2608.00.00 as a natural zinc ore suitable for concentration and smelting into zinc metal. It represents secondary zinc ores from weathered primary deposits.
Smithsonite Zinc Ore
Smithsonite (ZnCO₃) is a zinc carbonate ore formed through supergene enrichment in zinc deposits. It is imported under HTS 2608.00.00 as a zinc ore for roasting and leaching in zinc production. This ore type is common in nonsulfide zinc deposits.
Hemimorphite Zinc Ore
Hemimorphite (Zn₄Si₂O₇(OH)₂·H₂O) is a hydrated zinc silicate ore from oxidized zones of zinc deposits. HTS 2608.00.00 covers this ore as it is concentrated for zinc silicate flotation recovery. It serves as an important source for secondary zinc production.
Calamine Zinc Ore
Calamine refers to a mixture of zinc carbonate and silicate ores, historically mined for zinc extraction. Under HTS 2608.00.00, it qualifies as zinc ore when containing sufficient zinc for metallurgical recovery. Common in European and North American deposits.
Zinc-Lead Mixed Ore
Polymetallic ores containing both zinc and lead sulfides, such as those from Red Dog mine, with zinc as principal value. Classified under HTS 2608.00.00 when zinc predominates for separate concentration circuits. These ores require complex flotation separation.
