Asbestos-cement, of cellulose fibre-cement or the like

HS v2022 Code: 6811

About asbestos-cement, of cellulose fibre-cement or the like

HS code 6811 covers a range of construction materials made from asbestos-cement or cellulose fibre-cement. These materials are widely used in the building and construction industry due to their durability, fire resistance, and affordability. As a key component in the production of roofing, siding, and other construction elements, the 6811 industry plays a vital role in the broader economy, supporting infrastructure development and housing projects around the world.

Production process

The production of asbestos-cement and cellulose fibre-cement materials typically involves a process of mixing the raw materials, forming the desired shapes, and then curing the final products. The key steps include pulping and blending the asbestos or cellulose fibers, combining them with cement and other additives, and then extruding or molding the mixture into the required shapes. The products are then cured through a controlled drying and hardening process to achieve the desired strength and properties.

Production inputs

The main inputs for the 6811 industry include asbestos fibers, cellulose fibers, cement, and various other additives such as silica, calcium carbonate, and reinforcing materials. Specialized machinery, such as pulping equipment, mixing tanks, and extrusion or molding machines, are also essential for the production process. Additionally, the industry relies on a reliable supply of energy, water, and transportation infrastructure to support its operations.

Production outputs

The primary outputs of the 6811 industry are a range of construction materials, including roofing tiles, siding panels, pipes, and other building components. These products are widely used in the construction of residential, commercial, and industrial buildings, as well as in infrastructure projects such as roads, bridges, and dams. The outputs of the 6811 industry are often consumed by other construction-related industries, such as 4412 Builders' Joinery and Carpentry of Wood, 6810 Prefabricated Buildings, and 6812 Articles of Asbestos-Cement, of Cellulose Fibre-Cement or the Like.
