HS Code 44.07 – Wood sawn or chipped lengthwise, sliced or peeled, whether or not planed, sanded or finger-jointed, of a thickness exceeding 6mm

HS code 4407 is a 4-digit heading in the Harmonized System that covers: Wood sawn or chipped lengthwise, sliced or peeled, whether or not planed, sanded or finger-jointed, of a thickness exceeding 6mm. Heading 4407 is a cornerstone classification for primary processed timber in international trade, encompassing 'Wood sawn or chipped lengthwise, sliced or peeled, whether or not planed, sanded or finger-jointed, of a thickness exceeding 6mm.' This broad heading covers a vast array of lumber products, from rough-sawn timber to highly finished boards, as long as they meet the critical criterion of being sawn or chipped lengthwise and having a thickness greater than 6mm. It includes common construction materials like planks, beams, studs, and decking, as well as components for furniture, joinery, and other manufactured wood products. The 'whether or not planed, sanded or finger-jointed' clause indicates that various levels of surface finishing and joining techniques are permitted within this heading, reflecting its versatility. For trade compliance, accurate classification under 4407 is paramount as it influences duties, quotas, anti-dumping measures (e.g., softwood lumber disputes), phytosanitary requirements, and CITES regulations for certain species. This heading represents the core output of sawmills globally, forming the foundational material for much of the world's construction and wood manufacturing, and is central to Chapter 44's progression from raw logs to industrial wood products.

Douglas fir dimensional lumber, planed pine boards, rough-sawn oak beams, cedar decking planks, mahogany furniture stock, spruce wall studs, finger-jointed timber for framing, sanded maple flooring blanks, untreated hemlock planks, pressure-treated lumber for outdoor use, laminated veneer lumber (LVL) over 6mm, plywood core veneers (over 6mm), glulam beam components (sawn and glued, over 6mm), utility poles (sawn lengthwise, over 6mm), scaffold planks, timber for window frames, timber for door frames, sawn pallet wood (over 6mm), timber for garden sheds, large wooden posts, railway tie blanks (pre-shaping), structural timber for roofing, wood for boat building (over 6mm), timber for heavy construction.

The primary misclassification issue with 4407 is its thickness boundary. Products not exceeding 6mm in thickness are typically classified under 4408 (Veneering sheets). Conversely, unworked wood in the rough (e.g., logs not sawn lengthwise) belongs to 4403. Another common error is confusing 4407 with 4409 (Wood, continuously shaped) if the timber has been continuously shaped along any of its edges or faces (e.g., tongue and groove flooring, molded lumber). The key differentiator for 4407 is 'sawn or chipped lengthwise' with a thickness 'exceeding 6mm,' without continuous shaping or being a finished laminated product.

In 2025, the top exporters of HS code 4407 in UN Comtrade data were Canada ($6.1B, 16% of world exports), Sweden ($4.4B) and Russia (about $3.0B). World exports came to about $38.7B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 4407 in UN Comtrade data were the United States ($7.4B, 19% of world imports), China ($6.4B) and the United Kingdom ($2.7B). World imports came to about $38.9B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 4407 is a 4-digit heading under Chapter 44 of the Harmonized System. The first 2 digits (44) identify the chapter, and digits 3-4 (07) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
