Cellulose fibre-cement; articles or the like; corrugated sheets, not containing asbestos

HS code 681181 covers the production and trade of cellulose fibre-cement products, a versatile construction material used in a variety of applications. This industry plays a crucial role in the building and infrastructure sectors, providing durable and cost-effective solutions for roofing, siding, and other construction elements. As a non-asbestos alternative to traditional cement-based products, the cellulose fibre-cement industry has gained significant traction in recent years, driven by increasing demand for sustainable and environmentally-friendly building materials.

The production of cellulose fibre-cement products typically involves a process known as the Hatschek process. This method combines cellulose fibers, cement, and other additives to create a slurry, which is then pressed and cured to form the desired corrugated sheets or other articles. The resulting products are known for their strength, durability, and resistance to weathering, making them a popular choice for both residential and commercial construction projects.

The main inputs required for the production of cellulose fibre-cement products include cellulose fibers, cement, and various additives such as silica, fillers, and reinforcing agents. Specialized machinery, such as Hatschek machines and curing ovens, are also essential for the manufacturing process. Additionally, the industry relies on a consistent supply of water and energy resources to support the production and curing of the fibre-cement materials.

The primary outputs of the cellulose fibre-cement industry are corrugated sheets, panels, and other construction articles. These products are widely used in the construction of roofs, facades, and other building elements. The outputs of this industry may be consumed by various other HS codes, including 441810 Wooden windows, French windows and their frames, 441820 Wooden doors and their frames and thresholds, and 681011 Building blocks and bricks of cement, concrete or artificial stone, among others.
