About HS Code 284920
Silicon carbide (SiC), whether chemically defined or not, is classified under this HS code. This advanced ceramic material is highly valued for its extreme hardness, high thermal conductivity, and chemical inertness, making it indispensable across a wide range of high-performance applications. It is extensively traded for use as an abrasive in grinding and polishing, as a refractory material in high-temperature furnaces, and increasingly as a semiconductor material in power electronics and LEDs due to its superior electrical properties compared to silicon. International trade is fueled by the demand from automotive, aerospace, electronics, and metallurgical industries. Exporters are typically countries with advanced materials processing capabilities, while importers are nations with robust manufacturing sectors requiring high-performance components. Its diverse forms, from powders to wafers, dictate specific trade routes and end-uses.
