Last updated: August 2026 dataQuarried or processed quartz in lump, chip, or granular form — distinct from naturally deposited sand — is split at the 10-digit level by iron oxide content, with high-purity material (≥95% silica, <0.6% iron oxide) under 2506100010 and all other forms under 2506100050. Turkey leads US import supply, followed by Canada and Norway, reflecting the geographic concentration of high-grade quartz deposits used in ferrosilicon smelting, silicon metal production, and engineered stone manufacturing. Purity documentation from the exporting mill is routinely required to support the correct 10-digit classification.

Heading 2506.10 covers quartz that occurs as rock or vein material — quarried, crushed, or otherwise processed from solid deposits — rather than naturally deposited sand. If the material was extracted as unconsolidated sand from a natural deposit, it belongs under 2505.10 regardless of its silica purity.
Norway hosts some of the world's highest-purity quartz deposits, particularly in the Rana region, which produce material meeting the stringent specifications required for solar-grade silicon and semiconductor applications. That exceptional purity justifies the logistics cost, making Norwegian quartz competitive for premium end uses even against closer sources.
