Wood, shuttering for concrete constructional work.
Classification of wooden formwork under HS 4418.40
Wooden formwork, often referred to as shuttering for concrete constructional work, is classified under HS code 4418.40. This classification falls under Heading 4418, which encompasses builders' joinery and carpentry of wood. Formwork is a critical component in the construction industry, acting as a temporary or permanent mold into which concrete is poured to create structural elements like walls, slabs, and columns. For a product to be classified under 4418.40, it must be more than just raw lumber; it must be prepared or assembled specifically for use as shuttering. This includes panels that have been treated or joined in a way that makes them ready for concrete pouring. The classification is based on the functional application of the wood in a construction context. It is important to note that the wood used for formwork is often resin-coated or specially treated to ensure it can be easily removed from the hardened concrete, but these treatments do not change its classification under 4418.40. The durability and structural integrity of the wood are key factors in its suitability for this classification.

Codes often confused with 4418.40
Common mistake. Wooden formwork is often misclassified under 4407, which covers simple sawn wood. However, 4407 is for raw materials, whereas 4418.40 requires the wood to be worked into a specific constructional component. Another common error is using 4412 for plywood panels. While plywood is often used for formwork, if it is sold as a specialized shuttering system with frames or specific treatments, 4418.40 is more appropriate than the general plywood code.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
