Pulleys and flywheels, including pulley blocks

HS v2017 Code: 848350

About pulleys and flywheels, including pulley blocks

hs code 848350 covers the import and export of pulleys and flywheels, including pulley blocks. These mechanical components are essential in a wide range of industrial applications, from manufacturing machinery to transportation equipment. Pulleys and flywheels play a crucial role in power transmission, energy storage, and motion control, making them a vital part of the global industrial landscape.

Production process

Pulleys and flywheels are typically produced through a combination of metal casting, machining, and assembly processes. The raw materials, such as steel or aluminum, are first cast into the desired shape, often using techniques like sand casting or die casting. The cast components are then machined to precise specifications, ensuring accurate dimensions and smooth surfaces. Finally, the pulleys and flywheels are assembled with other necessary parts, such as bearings and shafts, to create the final product.

Production inputs

The primary inputs for the production of pulleys and flywheels include ferrous and non-ferrous metals, such as 720810 Steel, 760110 Aluminum, and 722830 Steel wire. Additionally, manufacturers require specialized machinery and tools, including casting equipment, lathes, and precision measuring instruments. Skilled labor, particularly in the areas of metal fabrication and assembly, is also a significant input for this industry.

Production outputs

Pulleys and flywheels produced under hs code 848350 are used in a wide range of applications, including 842121 Machinery for filtering or purifying water, 842123 Machinery for filtering or purifying beverages, and 842129 Machinery for filtering or purifying liquids. These components are also essential in the production of 842131 Intake air filters for internal combustion engines, 842139 Parts of machinery for filtering or purifying liquids or gases, and 842199 Parts of machinery for filtering or purifying liquids or gases. The versatility of pulleys and flywheels ensures their widespread use across various industries.
