Silicon dioxide

HS v2022 Code: 281122

About silicon dioxide

HS code 281122 covers silicon dioxide, a ubiquitous compound that plays a vital role in numerous industries. Silicon dioxide, commonly known as silica, is a chemical compound composed of one silicon atom and two oxygen atoms. It is an essential raw material for a wide range of products, from construction materials to electronics, making it a crucial component of the global economy.

Production process

The production of silicon dioxide typically involves the extraction and processing of natural mineral deposits, such as quartz, sand, or diatomaceous earth. The raw material is then subjected to various purification and refining techniques, including washing, screening, and sometimes chemical treatment, to remove impurities and achieve the desired purity levels.

Production inputs

The main inputs required for the production of silicon dioxide include the raw mineral deposits, as well as energy sources, such as electricity or natural gas, to power the processing equipment. Depending on the specific application, additional chemicals or additives may be required to modify the properties of the final product.

Production outputs

The primary output of HS code 281122 is silicon dioxide, which is then used as a key ingredient in a wide range of industries. Some of the main consumers of silicon dioxide include the 681010 construction materials, 851790 electronic components, and 321490 chemical manufacturing sectors. Silicon dioxide is also used in the production of 330499 cosmetics and personal care products and as a 381512 catalyst in various chemical processes.
