Products classified under HTS 3802.90.20.00
Bentonite Clay Bleaching Earth
Activated bentonite clay processed through acid or thermal treatment to enhance its adsorptive properties for removing color impurities from vegetable oils. Classified under HTS 3802.90.2000 as an activated earth used primarily in edible oil refining. Its high surface area makes it effective for decolorization and purification processes.
Fuller's Earth Decolorizing Agent
Acid-activated fuller's earth derived from attapulgite or montmorillonite clays, used in the refining of petroleum oils and fats. Falls under HTS 3802.90.2000 due to its activation enhancing bleaching and purification capabilities. Essential for removing polar compounds in industrial refining.
Activated Attapulgite Clay Adsorbent
High-surface-area attapulgite clay activated for use in removing contaminants from beverages like wine and beer. HTS 3802.90.2000 applies to this activated natural mineral product designed for selective adsorption. Widely used in food and beverage processing industries.
Montmorillonite K10 Activated Clay Catalyst
Acid-treated montmorillonite K10 clay serving as a heterogeneous catalyst in organic synthesis reactions. Classified in HTS 3802.90.2000 as activated earth with catalytic adsorptive properties. Common in pharmaceutical and fine chemical manufacturing.
Zeolite Y Activated Powder for Gas Separation
Synthetic zeolite Y activated through calcination for molecular sieve applications in gas purification. Though mineral-like, its activation for adsorption qualifies it under HTS 3802.90.2000 as activated natural mineral product. Used in industrial oxygen concentrators and drying systems.
Diatomaceous Earth Activated Filter Aid
Calcined and flux-calcined diatomaceous earth activated for use as filter aid in beverage and pharmaceutical filtration. HTS 3802.90.2000 covers this activated siliceous earth enhancing filtration efficiency. Removes fine particles and clarifies liquids effectively.
Acid-Activated Kaolin Clay for Edible Oil Refining
Sulfuric acid-activated kaolin clay used as a bleaching adsorbent in palm and soybean oil refining processes. Meets HTS 3802.90.2000 criteria for activated earths with enhanced decolorizing capacity. Regenerable through solvent washing for multiple uses.
Spent Bleaching Earth Regenerated Adsorbent
Regenerated spent bleaching earth reactivated through thermal desorption for reuse in oil refining. Still qualifies under HTS 3802.90.2000 as activated earth despite prior use. Cost-effective sustainable alternative to virgin activated clays.
