wood, posts and beams other than products of subheadings 4418.81 to 4418.89.
Classification of timber posts under HS 4418.30
Timber posts are classified under HS code 4418.30. This classification falls under Heading 4418, which encompasses builders' joinery and carpentry of wood. To qualify for this code, the posts must be intended for use in building construction and must be further worked than simple sawn timber. This typically means they have been planed, sanded, or joined with other pieces, or they feature specific carpentry work such as tenons, mortises, or pre-drilled holes for structural assembly. The classification follows the logic that these are manufactured building components rather than raw materials. Under the 2022 HS nomenclature, 4418.30 serves as the category for posts and beams that do not meet the specific definitions of engineered products like glulam (4418.81) or CLT (4418.82). The classification is determined by the product's primary use as a structural support in a building frame, distinguishing it from decorative wood or raw lumber.

Codes often confused with 4418.30
Common mistake. A common misclassification occurs with HS code 4407, which covers wood sawn or chipped lengthwise. If a post is merely sawn and not further worked with carpentry joints or specific structural finishing, it remains in 4407. Additionally, posts are often confused with 4418.81 (Glulam) if they are made of laminated layers; however, 4418.30 is specifically for non-engineered or standard carpentry posts.

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).
