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 to numerous manufacturing sectors, this industry holds significant economic importance both domestically and globally.

Production process

The production of friction materials classified under HS code 681320 typically involves a multi-step process. Raw materials, such as asbestos fibers, resins, and fillers, are carefully blended and compounded. The mixture is then pressed into the desired shape, such as sheets, rolls, or segments, using specialized machinery. Heat and pressure are applied to cure and bind the materials, resulting in the final friction products.

Production inputs

The main inputs required for the production of friction materials under HS code 681320 include asbestos fibers, various resins (e.g., phenolic, epoxy), and fillers (e.g., mineral, metallic). Additionally, specialized machinery, such as mixing equipment, presses, and curing ovens, are essential for the manufacturing process. The availability and quality of these raw materials and equipment are critical factors in the industry.

Production outputs

The primary outputs of the industry covered by HS code 681320 are friction materials, including sheets, rolls, strips, segments, discs, washers, and pads. These products are primarily consumed by the 870000 Vehicles, other than railway or tramway rolling-stock, and parts and accessories thereof and 842000 Machinery, mechanical appliances, nuclear reactors, boilers; parts thereof industries, where they are used in the production of brakes, clutches, and other friction-based components.

Revisions to 681320
