Diatomaceous Earth Powder from Japan

Natural diatomite, a siliceous fossil meal derived from diatom skeletons, with an apparent specific gravity of less than 1. It is used as a filtration aid in food and beverage processing. Classified under HTS 2512.00.00.00 due to its low density and siliceous fossil origin, whether calcined or not.
