Products classified under HTS 2811.22.10.00
Synthetic Silica Gel Desiccant Packets
Small packets filled with synthetic silica gel beads used to absorb moisture in packaging for electronics, pharmaceuticals, and food products. Classified under HTS 2811.22.10.00 as synthetic silica gel, a chemically defined inorganic oxygen compound of silicon (silicon dioxide) produced synthetically. It meets Chapter 28 Note 1 criteria for separate chemically defined compounds.
High-Purity Synthetic Silica Gel for Chromatography
Amorphous synthetic silica gel with controlled pore size used as stationary phase in column chromatography for lab separations. Falls under HTS 2811.22.10.00 as synthetic silicon dioxide, a separate chemically defined compound per Chapter 28 notes, excluding organo-silicon derivatives.
Synthetic Silica Gel Beads for Gas Drying
Spherical beads of synthetic silica gel designed for industrial air and gas dehydration towers. HTS 2811.22.10.00 covers this as synthetic silicon dioxide, an inorganic oxygen compound of nonmetals, distinct from fused quartz or precipitated silicas.
Indicator Silica Gel with Cobalt Chloride
Synthetic silica gel impregnated with cobalt chloride that changes color from blue to pink when saturated. Still classified under HTS 2811.22.10.00 as the base is chemically defined synthetic silicon dioxide; impregnation doesn't change principal compound.
Synthetic Silica Gel Powder for Catalyst Support
Fine powder synthetic silica gel used as inert support for petroleum cracking catalysts. HTS 2811.22.10.00 applies to pure synthetic SiO2 before impregnation with active metals.
Food-Grade Synthetic Silica Gel Capsules
Encapsulated synthetic silica gel approved for moisture control in food packaging. Classified in HTS 2811.22.10.00 as synthetic silicon dioxide meeting food contact standards.
Synthetic Silica Gel for Pharmaceutical Packaging
Tyvek-wrapped synthetic silica gel units for blister packs and bottles to protect tablets from humidity. HTS 2811.22.10.00 for the synthetic SiO2 core.
Coarse-Pore Synthetic Silica Gel for Water Filtration
Synthetic silica gel with large pores used in preliminary water purification stages. Remains under HTS 2811.22.10.00 as pure synthetic silicon dioxide.
Self-Indicating Silica Gel in Reusable Containers
Reusable plastic jars filled with color-reversible synthetic silica gel for camera lens storage. HTS 2811.22.10.00 for the silica gel content.
Micronized Synthetic Silica Gel for Cosmetics
Ultra-fine synthetic silica gel used as mattifying agent and oil absorber in powders. Classifies under HTS 2811.22.10.00 as pure synthetic SiO2.
