CPC v2.1 Code: 311

About wood, sawn or chipped lengthwise, sliced or peeled, of a thickness exceeding 6 mm; railway or tramway sleepers (cross-ties) of wood, not impregnated

cpc code 311 covers a diverse range of wood products, including sawn or chipped lumber, sliced or peeled wood, and railway or tramway sleepers. This industry plays a crucial role in the global timber and construction supply chains, providing essential raw materials for a wide variety of applications. From residential and commercial construction to furniture manufacturing and transportation infrastructure, the products classified under cpc 311 are in high demand across numerous sectors of the economy.

Production process

The production of goods under cpc 311 typically involves several key steps. Logs are first harvested from forests and transported to sawmills or other processing facilities. The wood is then sawn, chipped, sliced, or peeled to the desired thickness, often using specialized machinery such as band saws, circular saws, or peeling lathes. For railway or tramway sleepers, the wood is further processed and treated to ensure durability and longevity when used in transportation infrastructure.

Production inputs

The main inputs required for the production of cpc 311 goods include raw timber, which is sourced from 031 Forestry and logging, as well as various types of machinery and equipment used in the sawing, chipping, slicing, and peeling processes. Energy sources, such as electricity or fuel, are also necessary to power the production equipment. Additionally, the industry may rely on transportation services to move the raw materials and finished products.

Production outputs

The primary outputs of cpc 311 include sawn or chipped wood, sliced or peeled wood, and railway or tramway sleepers. These products are then consumed by a variety of downstream industries, such as 321 Manufacture of wood and of products of wood and cork, except furniture; manufacture of articles of straw and plaiting materials, 422 Construction of roads and railways, and 381 Manufacture of furniture, among others.
