About millstones, grindstones, grinding wheels and the like; of other agglomerated abrasives or of ceramics

HS code 680422 covers a diverse range of abrasive products, including millstones, grindstones, and grinding wheels. These items play a crucial role in various manufacturing and processing industries, enabling the shaping, sharpening, and finishing of a wide array of materials. As a key component of many industrial operations, the products under this code contribute significantly to the broader economy, supporting the production of goods across multiple sectors.

Production process

The production of items classified under HS code 680422 typically involves the agglomeration of abrasive materials, such as natural or synthetic materials, with a binding agent. This mixture is then shaped and hardened into the desired form, such as a wheel or stone, through processes like molding, pressing, or sintering. The specific techniques used can vary depending on the intended application and the properties required for the final product.

Production inputs

The main inputs for the production of items under HS code 680422 include abrasive materials, such as 251320 natural emery, 251910 silicon carbide, or 281820 artificial corundum, as well as binding agents like resins or ceramics. Specialized machinery, such as molding presses and sintering furnaces, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce capable of operating these specialized production methods.

Production outputs

The products classified under HS code 680422 are primarily used as tools and components in various manufacturing and processing industries. They are often utilized for tasks such as grinding, polishing, and sharpening a wide range of materials, including metals, ceramics, and even certain types of 680510 natural or artificial abrasive powder or grain, on a base of textile material, of paper, of paperboard or of other materials. The outputs of this industry can be found in numerous applications, from 820310 files, rasps and similar hand tools, to 842240 machinery for cleaning, sorting or grading seed, grain or dried leguminous vegetables, and beyond.
