HS-4 · Heading
2849 — Carbides, whether or not chemically defined
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2849 when importing carbides, such as calcium carbide used in acetylene production or silicon carbide used for abrasives. Correct classification is crucial to ensure compliance and avoid delays at customs.
When determining the appropriate HS-6 subheading, consider the specific type of carbide. For example, HS-6 284910 is for calcium carbides, which are often used in chemical synthesis, while HS-6 284920 is for silicon carbides, typically utilized in high-performance applications like cutting tools.
If your product does not fall under calcium or silicon, you may classify it under HS-6 284990, which covers other carbides. This includes materials like tungsten carbide, commonly used in industrial machinery. Ensure you have documentation to support your classification.
