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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coarse grains over 2mm for filtration
Coarser silica sands for water filtration or construction fall under the specific 'coarse' subheading.
If graded, washed, and prepared as abrasives
Post-processing like sizing or cleaning transforms natural sand into artificial abrasives.
If refractory grade for high-temp kilns
Silica sands meeting refractory specs with low impurities are classified as prepared refractories.

Import Tips & Compliance
• Verify SiO2 content via lab analysis to confirm classification as natural silica sand, avoiding reclassification to synthetic silica (2811)
• Provide geological origin certificates to distinguish from metal-bearing sands in Chapter 26
• Ensure bulk packaging documentation specifies 'unprocessed natural sand' to prevent duties under finished abrasives (6805)

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.
