Synthetic Amorphous Silica Gel from Japan
Synthetic amorphous silica gel is a porous, granular form of silicon dioxide produced by acidifying sodium silicate. It is a chemically defined inorganic compound of silicon dioxide, which falls under tariff item 2811.22.00 as 'other inorganic oxygen compounds of non-metals.' Its primary use as a desiccant does not alter its classification as a basic chemical.

Import Tips
• Ensure the silica gel is not mixed with cobalt chloride or other indicators that could change its classification
• Declare the product as silicon dioxide (CAS 7631-86-9) to avoid delays
• Keep technical datasheets showing it is synthetic and amorphous, not crystalline, as crystalline forms may face different scrutiny
