High-Purity Silica Sand for Glass Manufacturing
This ultra-pure silica sand contains 95% or more silica and no more than 0.6% iron oxide, making it ideal for producing high-clarity glass such as bottles and windows. Its low iron content prevents discoloration in the final glass product. Classified under HTS 2505.10.10.00 due to meeting the strict silica purity and iron oxide limits.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If iron oxide exceeds 0.6% by weight
Higher iron content disqualifies it from the ultra-low iron subheading, moving to other high-silica sands.
If silica content below 95% but still classified as natural sand
Falls under other silica/quartz sands if purity threshold not met.
If chemically processed or prepared for specific industrial use
Processed preparations of chemicals like washed or acid-treated sand shift to Chapter 38.

Import Tips & Compliance
• Obtain mill test reports certifying silica content ≥95% and iron oxide ≤0.6% to avoid reclassification
• Ensure proper packaging to prevent contamination during transit, as purity is critical for end-use
• Declare exact chemical analysis; common pitfall is mislabeling as general silica sand
