Railway or tramway sleepers (cross-ties) of wood

HS v2017 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 of rail infrastructure play a crucial role in the transportation industry, providing a stable and durable foundation for railway tracks. The production and trade of wooden sleepers is a significant economic activity, supporting the construction and maintenance of rail networks worldwide.

Production process

Wooden railway sleepers are typically produced through a process of sawing, shaping, and treating. Logs are first cut to the desired length, then shaped into the characteristic rectangular or square cross-section. The sleepers are then subjected to various preservation treatments, such as pressure impregnation with preservatives, to enhance their durability and resistance to weathering and decay.

Production inputs

The main inputs for the production of HS code 4406 wooden sleepers include high-quality timber, typically from hardwood species like oak, beech, or pine. Specialized machinery, such as sawmills, planers, and treatment facilities, are also essential for the manufacturing process. Additionally, preservative chemicals and other treatment materials are required to ensure the long-term performance of the sleepers.

Production outputs

The primary output of HS code 4406 is the wooden railway or tramway sleeper, which is a critical component in the construction and maintenance of rail infrastructure. These sleepers are consumed by 4907 Railway or tramway passenger transport services, 4908 Railway or tramway freight transport services, and 4203 Construction of railways and underground railways.
