About HS Code 281122

Silicon dioxide, commonly known as silica, falls under this HS code and is a fundamental compound with vast industrial applications, making it a significant item in international trade. It's the primary component of sand and quartz, but in trade, it often refers to processed forms like fumed silica, precipitated silica, and silica gel. Key industries importing and exporting silicon dioxide include electronics (semiconductors), construction (cement, glass), rubber and plastics (fillers), paints and coatings, and food processing (anti-caking agent). Countries with advanced manufacturing capabilities and significant raw material deposits, such as China, the United States, Germany, and Japan, are major players. The trade is driven by its versatility, acting as a reinforcing filler, abrasive, desiccant, or optical material, with purity and particle size being critical specifications.

Products Under This Code
