Green Silicon Carbide Micronized Powder 1200 Mesh
Green silicon carbide micronized to 1200 mesh, produced via Acheson process with higher purity, ideal for bonded abrasives and refractories. It qualifies for HTS 2849.20.20.00 due to its refined, pulverized state as a chemically defined carbide of silicon. The green color indicates low iron impurities.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in crude block or lump form before refinement
Pre-refined crude silicon carbide is classified separately under 2849.20.10.00.
If aluminum oxide content predominates
Products primarily of aluminum oxide, even with silicon carbide, fall under the aluminum oxide subheading in the same chapter.
If prepared as mixed refractory grains with other materials
Blended into specific refractory preparations, it becomes a mixed chemical product under heading 3817.
