Quartz Silica Sand for Solar Panel Glass
Processed quartz sand with 95-98% silica and iron <0.5%, specifically manufactured for low-iron float glass used in photovoltaic panels. Falls under HTS 2506.10.0010 as non-natural quartz sand meeting the silica/iron parameters after milling and flotation purification. Critical for producing clear glass that maximizes solar transmission.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If higher iron content tolerated for solar glass
Sands exceeding 0.6% iron oxide, even for similar uses, shift to 2506.20 with potentially different duties.
If agglomerated into composite blocks
If bound with resins into sheets or shapes, it becomes 'articles of stone or similar materials' in 6815.
If calcined and used as pigment extender
Calcined silica preparations for paints shift to Chapter 32 as prepared pigments.

Import Tips & Compliance
• Submit process flow diagrams showing quartz crushing/screening to prove non-natural status for 2506.10.0010
• Batch-test for iron content variability; inconsistent lots may require re-testing and risk reclassification

High-Purity Silica Sand for Glass Manufacturing
This artificial silica sand contains over 95% silica and less than 0.6% iron oxide, produced by crushing and washing quartz to remove impurities. It is classified under HTS 2506.10.0010 as processed quartz sand (other than natural) meeting the strict purity specifications for optical and container glass production. The low iron content prevents discoloration in high-clarity glass products.
