Quartz Sand for Water Filtration from China
Washed quartz sand, graded to 0.5-1.0mm, is used in municipal water filtration systems. The washing process removes impurities without changing the sand's structure, as permitted by Chapter Note 1. Its natural origin and lack of further processing keep it classified under heading 25.05.

Import Tips
• Document that the sand has only been washed and graded, not subjected to heat or chemical treatment, to avoid reclassification
• Confirm the grain size range matches the product specification for filtration use
• Be aware that if the sand is coated with a filter aid or chemical, it may fall under Chapter 38
