Products classified under HTS 3802.10.00.50
Granular Activated Carbon GAC-12x40
Granular activated carbon with 12x40 mesh size, derived from coconut shells, used for water purification by adsorbing organic contaminants. Classified under HTS 3802.10.0050 as 'other' activated carbon, excluding forms specifically listed like powder or for sugar refining. High surface area of over 1000 m²/g enables efficient pollutant removal.
Coconut Shell Activated Carbon Pellets 4mm
Cylindrical pelletized activated carbon from coconut shells, 4mm diameter, optimized for gas phase adsorption in air purification systems. Falls under HTS 3802.10.0050 as 'other' activated carbon not in powder form or for specific refining uses. Exceptional hardness reduces dust formation in high-flow applications.
Wood-Based Activated Carbon Powder 325 Mesh
Fine 325 mesh activated carbon powder from hardwood, used in gold recovery and wastewater treatment. Although powdery, classified under 'other' 3802.10.0050 if not meeting exact principal subheading criteria. High microporosity ideal for heavy metal adsorption.
Impregnated Activated Carbon with Potassium Iodide
Granular activated carbon impregnated with potassium iodide for H2S removal in biogas treatment. HTS 3802.10.0050 as base activated carbon; impregnation enhances chemisorption. Widely used in wastewater digesters.
Acid-Washed Coconut Activated Carbon 8x30
8x30 mesh coconut shell activated carbon post-acid washed for low ash metals content, used in ultrapure water systems. 'Other' under 3802.10.0050 due to specialized treatment. Meets semiconductor grade purity standards.
Spent Activated Carbon from Gold Leaching
Regenerable spent activated carbon from cyanide gold leaching circuits, containing adsorbed gold complexes. HTS 3802.10.0050 as spent animal black includes similar exhausted carbons. Returned for thermal reactivation.
High-Density Bone Char 30x60 Mesh
Bone char (animal black) 30x60 granular form from bovine bones, used for sugar decolorization. Technically activated animal black under 3802.10.0050 'other'. Phosphate content aids fluoride removal.
Steam-Activated Bamboo Charcoal Granules
Granular steam-activated charcoal from bamboo, sustainable alternative for air purifying bags. HTS 3802.10.0050 as other activated carbon from vegetable sources. Natural deodorizing properties.
Iron-Impregnated Activated Carbon for Arsenic Removal
Granular activated carbon impregnated with ferric oxide for arsenic adsorption from groundwater. 'Other' activated carbon 3802.10.0050 with catalytic enhancement. NSF-certified for potable water.
Coal-Based Extruded Activated Carbon 3x8 Mesh
Extruded activated carbon from bituminous coal, 3x8 mesh, designed for VOC removal in industrial ventilation. HTS 3802.10.0050 covers this 'other' form of activated carbon with high mechanical strength. Effective for solvent recovery due to tailored pore structure.
