Products classified under HTS 2505.10.50.00
Industrial Silica Sand 99.8% Purity
High-purity silica sand with 99.8% SiO2 content, sourced from quartz deposits and minimally processed for uniformity. Classified under HTS 2505.10.5000 as 'other' silica sands, excluding metal-bearing sands, suitable for glass manufacturing and foundry applications. It meets the natural sands definition without exceeding purity thresholds for chemical products.
Quartz Foundry Sand AFS 50-55
Naturally occurring quartz sand sieved to AFS 50-55 grain fineness for metal casting molds. Falls under HTS 2505.10.5000 as 'other' silica/quartz sands, distinguished by natural origin and lack of chemical binders. Ideal for green sand molding in iron and steel foundries.
Colored Silica Sand for Landscaping
Natural silica sand naturally colored by mineral deposits (e.g., red from iron oxides), used in decorative landscaping and playground surfaces. Classified in HTS 2505.10.5000 per hierarchy for 'other' colored silica sands, explicitly including naturally colored varieties excluding metal-bearing types.
Quartz Sand for Water Filtration
Washed quartz sand graded 0.5-1.0mm for municipal water treatment filters. HTS 2505.10.5000 covers this as 'other' natural silica/quartz sands, with washing not constituting sufficient processing to shift headings.
Glass Grade Silica Sand
Low-iron silica sand (<0.02% Fe2O3) from natural deposits for container glass production. Fits HTS 2505.10.5000 as 'other' silica sands, with iron content verified below metal-bearing thresholds.
Playground Silica Sand
Rounded silica sand grains 0.3-0.8mm, naturally sourced for safety in children's play areas. Under HTS 2505.10.5000 for 'other' natural sands, meeting angularity specs without processing beyond washing.
Ceramic Tile Silica Sand
Fine-ground natural silica sand for ceramic body and glaze formulations. Classified HTS 2505.10.5000 as 'other' quartz sands used in traditional ceramics.
Paint Filler Silica Sand
Micaceous silica sand providing texture and durability in architectural paints. HTS 2505.10.5000 for natural sands used as extenders, not precipitated forms.
Construction Silica Sand
Natural silica sand for mortar, concrete admixture, and shotcrete applications. Under 'other' HTS 2505.10.5000, excluding processed aggregates.
Frac Sand Silica 100 Mesh
High-sphericity silica sand 100 mesh (0.15mm) from Appalachian quartzite for hydraulic fracturing. HTS 2505.10.5000 'other' despite sphericity from natural tumbling.
