About asbestos-cement; articles or the like, containing asbestos

HS code 681140 covers a range of products containing asbestos, a naturally occurring mineral with unique properties that make it useful for various industrial applications. Asbestos-cement products, such as roofing tiles, pipes, and sheets, have been widely used in construction and infrastructure projects due to their durability, fire resistance, and affordability. This industry plays a crucial role in the global construction and building materials sector, supporting the development of essential infrastructure and housing worldwide.

Production process

The production of asbestos-cement products typically involves a process called the Hatschek process. This method combines asbestos fibers, cement, and water to create a slurry, which is then pressed and cured to form the desired products. The asbestos fibers act as reinforcement, enhancing the strength and resilience of the final products. Specialized machinery and equipment are used to ensure consistent quality and efficient production.

Production inputs

The main inputs for the asbestos-cement industry include 252490 Asbestos as the primary raw material, as well as cement, water, and various additives or fillers. Specialized machinery, such as mixing tanks, pressing equipment, and curing chambers, are also essential for the production process. The availability and cost of these inputs can significantly impact the industry's overall competitiveness and profitability.

Production outputs

The primary outputs of the asbestos-cement industry are a range of construction materials, including roofing tiles, pipes, sheets, and other articles containing asbestos. These products are widely used in the construction and infrastructure sectors, as they offer durability, fire resistance, and cost-effectiveness. The outputs of this industry may be consumed by various other 44 Wood and articles of wood; wood charcoal, 68 Articles of stone, plaster, cement, asbestos, mica or similar materials, and 69 Ceramic products industries, which utilize these materials in their own construction and building projects.
