Heading 2849 — Carbides, whether or not chemically defined
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 284920 when importing or exporting silicon carbides, such as those used in abrasives or as semiconductor materials. For example, a shipment of silicon carbide powder for industrial grinding applications falls under this code.
This subheading specifically covers silicon carbides, distinguishing them from other carbides like tungsten or boron carbides, which are classified under different HS codes. If you're dealing with those materials, you’ll need to look at HS-6 284930 instead.
Silicon carbides can be found in various forms, including granules, powders, or even as part of composite materials. They are often utilized in high-performance applications, such as in the production of cutting tools or as a substrate in electronic devices.
When classifying your products, ensure you’re aware of the specific chemical composition and intended use, as this can affect the correct HS classification. For example, silicon carbide used in ceramics may have different requirements than that used in electronics.
