Railway or tramway sleepers (cross-ties) of wood
HS v2022 Code: 4406
About railway or tramway sleepers (cross-ties) of wood
HS code 4406 covers railway or tramway sleepers (cross-ties) made of wood. These essential components form the foundation of rail infrastructure, providing a stable and durable base for railway tracks. The production and trade of wooden sleepers is a crucial part of the global transportation and logistics industry, supporting the movement of goods and people across vast distances.
Production process
Wooden railway sleepers are typically produced through a multi-step process. First, the raw timber is harvested and processed into the required dimensions. The wood is then treated with preservatives, such as creosote or copper-based compounds, to enhance its resistance to weathering, decay, and insect damage. Finally, the treated sleepers are cut, shaped, and prepared for installation along railway lines.
Production inputs
The main inputs for the production of HS code 4406 wooden railway sleepers include high-quality timber, typically hardwood species like oak, beech, or pine. Specialized machinery, such as sawmills, planers, and treatment facilities, are also essential for the manufacturing process. Additionally, the industry relies on a range of chemicals and preservatives to ensure the durability and longevity of the final product.
Production outputs
Wooden railway sleepers produced under HS code 4406 are primarily used in the construction and maintenance of railway infrastructure. These sleepers are essential components that support the rails and distribute the weight of trains, ensuring the stability and safety of rail transport. The output of this industry is often consumed by 8601 Railway locomotives and 8602 Other rail locomotives, as well as 8603 Self-propelled railway or tramway coaches, vans and trucks, and 8604 Railway or tramway maintenance or service vehicles.
