Silicon dioxide
Heading 2811 — Inorganic acids and other inorganic oxygen compounds of non-metals; n.e.c. in heading no. 2806 to 2810
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 281122 when importing or exporting silicon dioxide, commonly found in products like glass, ceramics, and abrasives. For example, a shipment of silica sand used in glass manufacturing falls under this code.
This code specifically covers silicon dioxide in its various forms, such as crystalline and amorphous silica. It differs from HS-6 281121, which pertains to silicon oxides, highlighting the importance of precise classification.
Silicon dioxide is a key ingredient in many industrial applications, including the production of silicon chips and as a filler in rubber and plastics. Understanding the specific form of silicon dioxide is crucial for proper classification.
When dealing with silicon dioxide, consider its packaging and intended use. For instance, bulk shipments of silica gel for moisture control in packaging may also require this HS code.
