Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If 95%+ SiO2 for glass manufacturing
Higher purity sands specifically for glass production have a dedicated subheading.
If chemically prepared for foundry cores
Addition of binders or chemical treatments makes it a prepared chemical product.
If formed into refractory bricks
Sintered or shaped silica sands become refractory bricks of Chapter 69.

Import Tips & Compliance
ā¢ Include sieve analysis reports showing natural grain distribution to avoid classification as manufactured media
ā¢ Declare exact moisture content under 3% to comply with natural sand definitions
ā¢ Avoid commingling with resin-coated sands, which shift to Chapter 38 as chemical preparations
