Quartz Sand for Water Filtration
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.
