About centrifuges; parts thereof, including parts for centrifugal dryers

HS code 842191 covers the classification of centrifuges and their component parts, including those used in centrifugal dryers. Centrifuges are essential industrial equipment found across a wide range of sectors, from manufacturing and processing to medical and scientific applications. They play a crucial role in separating solid particles from liquids or gases, making them indispensable in numerous industrial processes and contributing significantly to the broader economy.

Production process

The production of centrifuges typically involves the fabrication of various components, including the rotor, casing, motor, and control systems. Manufacturers use precision engineering techniques to ensure the accurate balancing and smooth operation of the centrifuge. The assembly process often involves the integration of specialized materials, such as high-strength alloys, to withstand the significant forces generated during operation.

Production inputs

The production of centrifuges requires a range of inputs, including specialized metals and alloys for the rotor and casing, as well as motors, bearings, and electronic control systems. Manufacturers may also rely on advanced manufacturing equipment, such as CNC machines and welding systems, to ensure the quality and precision of the final product. Additionally, the industry may consume inputs from related 842119 Centrifuges, including centrifugal dryers and 842121 Dryers classifications.

Production outputs

Centrifuges produced under HS code 842191 find applications across various industries, including 2834 Chemical products, 3011 Pharmaceutical products, 2893 Machinery for food, beverage and tobacco processing, and 2892 Machinery for mining, quarrying and construction. These centrifuges are used for tasks such as solid-liquid separation, particle size classification, and the concentration of valuable materials. The outputs of this industry may also be consumed by other 8421 Centrifuges, including centrifugal dryers; filtering or purifying machinery and apparatus, for liquids or gases classifications.
