Precipitated Silica Powder from Japan

Precipitated silica is a form of synthetic amorphous silicon dioxide produced by precipitation from a solution containing silicate salts. It falls under HTS 2811.22.5000 as 'other' silicon dioxide, distinct from natural diatomaceous earth or fused quartz, used primarily as a reinforcing filler in rubber and tire manufacturing.

Import Tips

Verify purity and amorphous structure via lab analysis to confirm classification as synthetic silicon dioxide under 2811, not mineral products

Include Certificate of Analysis (COA) showing SiO2 content >99% and production method to prevent reclassification as commodity chemicals
