Natural Silica Sands and Quartz Sands imports of $2.5M in July 2026 ran 45% above the year-to-date monthly average of $1.7M.
Last updated: July 2026 dataPurity grade is the defining classification variable for natural silica and quartz sands: the US schedule distinguishes sand with silica content of 95% or greater and iron oxide below 0.6% (2505101000) — a specification critical for glassmaking and semiconductor-grade applications — from lower-purity material classified as NESOI (2505105000). Canada is the leading supplier to the US market, reflecting geographic proximity and well-developed industrial mining infrastructure. These sands are foundational inputs for flat glass, foundry molds, hydraulic fracturing, and water filtration systems.

Sand with silica content of 95% or more by weight and iron oxide content below 0.6% by weight is classified under 2505101000. Material that does not meet both thresholds falls under the NESOI line 2505105000. Laboratory certificates of analysis documenting these parameters are essential for correct classification.
No broad Section 301 or antidumping orders are currently in place specifically targeting natural silica sands as a category, but importers should verify current CBP guidance and any applicable Section 232 or other measures with a licensed customs broker, as trade-remedy landscapes can change.
