45 declarable lines

Heading 4418 covers builders' joinery and carpentry of wood, including cellular wood panels, assembled flooring panels, shingles and shakes, and engineered structural timber products. It is split first by article type, such as windows, doors, posts and beams, formwork, flooring panels, and structural products, then by wood type, construction, and whether the product is bamboo or other wood.

How to choose the right subheading

Identify the article type first: window, door, post or beam, formwork, shingle, flooring panel, engineered structural product, or other article.
Check the wood species for windows and doors, since tropical wood and other wood have separate lines.
For flooring panels, check whether the product is bamboo or other wood, solid or multilayer, and the face ply thickness.
For structural products, check whether it is glulam, cross-laminated timber, an I-beam, or another engineered member.
Confirm whether the product is an assembled panel or article rather than loose shaped wood strips.
