Silicon Carbide Powder 600 Grit FFP
This is a high-purity silicon carbide (SiC) powder, graded at 600 grit, used for precision lapping and polishing of optical components, ceramics, and metals. As a chemically defined compound of silicon and carbon, it falls squarely under tariff item 2849.20.00 for carbides of silicon, whether or not chemically defined. The product is not mixed with binders or other materials that would remove it from this heading.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the powder is blended with other substances for a specific industrial use
Mixtures containing silicon carbide with added materials for particular applications fall under chemical products and preparations of Chapter 38.
If the product is in the form of bonded abrasive wheels or stones
Articles of agglomerated abrasives, such as grinding wheels made from silicon carbide, are classified in Chapter 68.
If the carbide is of a metal other than silicon
Other carbides, such as boron or tungsten carbide, fall under this sibling tariff item.

Import Tips & Compliance
• Ensure the product is clearly labelled as silicon carbide (SiC) with purity and grit size on the commercial invoice to support classification under 2849.20.00
• If the powder is mixed with any organic binders or additives, it may shift to another heading—confirm with the CBSA before shipping
• Keep a safety data sheet (SDS) handy, as silicon carbide dust may be subject to workplace hazard regulations
