Machine-tools; grinding or polishing machines, for working stone, ceramics, concrete, asbestos-cement or like mineral materials or for cold working glass

HS code 846420 covers a range of machine-tools used for grinding, polishing, or otherwise working with hard, mineral-based materials such as stone, ceramics, concrete, and glass. These specialized machines play a crucial role in various industries, from construction and manufacturing to art and architecture, enabling the precise shaping and finishing of a wide array of products and components.

Machines falling under HS code 846420 typically utilize abrasive tools, such as grinding wheels or polishing pads, to remove material from the workpiece and achieve the desired shape and surface finish. The workpiece may be held in place by a variety of clamping mechanisms, and the machine's movement and speed can be precisely controlled to ensure consistent and accurate results. Some machines may also incorporate additional features, such as cooling systems or dust extraction, to enhance the efficiency and safety of the production process.

The primary inputs for the production of HS code 846420 machines include high-quality steel or other durable materials for the machine's frame and components, as well as specialized abrasive tools and accessories. Manufacturers may also require advanced control systems, sensors, and other electronic components to enable the precise control and monitoring of the machine's operation. Additionally, the production of these machines often relies on skilled technicians and engineers to design, assemble, and maintain the equipment.

The machines covered by HS code 846420 are used in a wide range of industries, producing a variety of finished products and components. These machines may be used to shape and finish stone, ceramic, and concrete products, such as 680210 tiles, 680291 monumental or building stone, and 681011 building blocks. They may also be used in the production of 700711 safety glass, 701990 other glass articles, and various industrial and construction materials. The output of these machines is often consumed by industries such as 251100 cement, 680100 worked monumental or building stone, and 681011 building blocks of cement, concrete or artificial stone.
