Product classification
HS code for Wooden beams: 4418.30
wood, posts and beams other than products of subheadings 4418.81 to 4418.89.
Classification of wooden beams under HS 4418.30
Wooden beams are classified under HS code 4418.30 because they represent builders' joinery and carpentry of wood. Unlike raw timber, these products have been further worked or assembled for use in the construction of buildings. The classification specifically excludes engineered structural timber products such as glue-laminated timber (glulam) or cross-laminated timber (CLT), which are categorized under subheadings 4418.81 through 4418.89. To qualify for 4418.30, the beams must be intended for structural support in a building framework and typically show evidence of joinery, such as tenons, mortises, or lap joints. If the wood is simply sawn or chipped lengthwise but not further worked into a specific structural component, it would fall under a different chapter entirely. The Harmonized System distinguishes between wood as a raw material and wood as a manufactured construction component. Under 4418.30, the focus is on the utility of the beam as a post or support member in carpentry. This includes solid wood beams that have been planed, sanded, or finger-jointed to achieve specific lengths and structural integrity required for architectural applications. The classification process requires verifying that the beam is not merely a piece of lumber but a finished or semi-finished component of a building's skeleton.

Codes often confused with 4418.30
Common mistake. Wooden beams are frequently misclassified under HS code 4407, which covers wood sawn or chipped lengthwise. The distinction lies in the degree of processing; 4407 is for raw lumber, while 4418.30 is for builders' joinery. Additionally, engineered beams like glulam must be classified under 4418.81, and cross-laminated timber under 4418.82. Confusing these with 4418.30 can lead to significant duty discrepancies.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
