Products classified under Tariff item 26.09
Alluvial Cassiterite Gravel
Alluvial cassiterite gravel is a natural tin ore concentrate recovered from placer mining operations. It consists of cassiterite pebbles with a tin yield of 5-15% after washing, making it suitable for gravity-based beneficiation. This product falls under tariff item 2609.00.00 as a tin ore and concentrate.
2609.00.00Cassiterite Ore
Cassiterite ore is the primary mineral ore of tin, appearing as dark brown to black crystals or granular masses containing 50-70% tin oxide. It is imported for direct metallurgical processing to extract tin metal. This ore falls under tariff item 2609.00.00 as a tin ore and concentrate.
2609.00.00Flotation Tin Concentrate from Skarn Deposits
Flotation tin concentrate from skarn deposits is a fine-particle concentrate produced by froth flotation, containing 40-55% tin in cassiterite form. It is imported for refining into tin metal used in electronics soldering. This concentrate falls under tariff item 2609.00.00 as a tin concentrate.
2609.00.00High-Grade Bolivian Tin Ore
High-grade Bolivian tin ore is premium ore from vein deposits, primarily cassiterite with over 60% SnO2 content, mined and minimally crushed for export. It is imported as unrefined tin ore for metallurgical processing. This ore falls under tariff item 2609.00.00.
2609.00.00Indonesian Offshore Tin Concentrate
Indonesian offshore tin concentrate is dredged from seabed placer deposits and processed to 30% tin content via onboard plants. It is a marine-derived tin concentrate imported for smelting. This concentrate falls under tariff item 2609.00.00 as a tin concentrate.
2609.00.00Malaysian Tin Ore Lumps
Malaysian tin ore lumps are hand-sorted lump ore from primary deposits, consisting of cassiterite lumps 10-50mm with high tin purity. They are imported for crushing and smelting in alloy production. This ore falls under tariff item 2609.00.00 as a tin ore.
2609.00.00Secondary Tin Concentrate from Tailings
Secondary tin concentrate from tailings is reprocessed from historic tin mine tailings and upgraded to 20% tin via modern flotation. It is a tin concentrate distinct from primary slag residues. This concentrate falls under tariff item 2609.00.00 as a tin concentrate.
2609.00.00Stream Sediment Tin Concentrate
Stream sediment tin concentrate is recovered from alluvial stream sediments via gravity separation, rich in cassiterite particles with 10-20% tin content. It is a natural tin ore concentrate imported for direct use in tin extraction. This concentrate falls under tariff item 2609.00.00.
2609.00.00Tin Ore from Greisen Deposits
Tin ore from greisen deposits is coarse-crushed ore from greisen-hosted cassiterite deposits, with tin grades of 1-3% suitable for heap leaching or milling. It is a raw tin ore imported for further processing. This ore falls under tariff item 2609.00.00 as a tin ore.
