About friction material and articles thereof (e.g. sheets, rolls, strips, segments, discs, washers, pads) not mounted; for brakes, clutches or the like, with a basis of asbestos
HS code 681320 covers a critical component of the automotive and industrial machinery industries - friction materials used in brakes, clutches, and similar applications. These materials play a vital role in the safe and efficient operation of a wide range of equipment, from passenger vehicles to heavy machinery. As a key input for numerous manufacturing sectors, the production and trade of these friction materials are essential to the broader global economy.
Production process
Friction materials under HS code 681320 are typically produced through a combination of molding, pressing, and bonding processes. Raw materials, such as asbestos fibers, resins, and fillers, are carefully blended and then formed into the desired shapes and sizes, often using high-pressure hydraulic presses. The resulting friction components may undergo additional finishing steps, such as grinding or polishing, to ensure precise dimensions and optimal performance characteristics.
Production inputs
The main inputs required for the production of friction materials under HS code 681320 include asbestos fibers, various resin binders (e.g., phenolic, epoxy, or silicone resins), and filler materials (such as mineral fillers or metal powders). Specialized production equipment, including molding machines, presses, and finishing tools, are also essential for this industry. Additionally, the manufacturing process may require access to reliable sources of energy, water, and other utilities to ensure consistent and efficient production.
Production outputs
Friction materials produced under HS code 681320 are primarily used as components in brakes, clutches, and similar friction-based systems found in a wide range of industries. These friction materials are often consumed by manufacturers of 870840 motor vehicle brakes and servo-brakes and 842199 parts of machinery, as well as producers of industrial equipment, such as 842890 machinery for the industrial preparation or manufacture of food or drink. The versatility of these friction materials allows them to be utilized across numerous sectors, contributing to the overall efficiency and safety of a diverse range of products and applications.
