wood, posts and beams other than products of subheadings 4418.81 to 4418.89.
Classification of wooden posts under HS 4418.30
Wooden posts are classified under HS code 4418.30 because they represent builders' joinery and carpentry of wood. According to the General Rules of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes. Heading 4418 specifically covers wood used in the construction of buildings. Subheading 4418.30 is designated for posts and beams that are not engineered structural timber products like cross-laminated timber or glue-laminated timber. These items are typically structural components that have been further worked than simple sawn timber, often featuring joints or specific shaping for architectural integration. The classification assumes the posts are intended for permanent installation in a structure, distinguishing them from simple lumber or decorative items. The presence of joinery, such as mortise and tenon joints, or being part of a prefabricated structural kit, further solidifies this classification under Chapter 44. The wood must be the constituent material that provides the essential character of the structural support.

Codes often confused with 4418.30
Common mistake. Wooden posts are frequently confused with HS code 4407, which covers wood sawn or chipped lengthwise. The distinction lies in the level of processing; 4407 is for basic lumber, while 4418.30 requires evidence of joinery or carpentry. Additionally, engineered products like glulam or CLT are often misclassified here but should be placed under 4418.81 to 4418.89. Fence posts that are merely pointed and not structural are often incorrectly placed here instead of 4404.

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).
