Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the quartz sand is in its natural state and not artificially processed
Natural silica sands are classified under heading 25.05, which covers sands of all kinds, including quartz sands, when not subjected to processing beyond washing or sieving.
If the sand is imported as part of a glass-making batch or mixed with other ingredients
Glass in the rough or glass cullet, as well as glass in the form of powder, granules or flakes, falls under Chapter 70 when the product is prepared for glass manufacturing.

Import Tips & Compliance
• Ensure the quartz sand is artificially processed (e.g
• flotation) and not natural sand, as this affects classification
• Provide a certificate of analysis showing SiO2 and iron content to support the tariff classification
• Verify whether the sand qualifies for duty-free treatment under any trade agreements applicable to your country of origin
