Product classification
HS code for Wood dryer: 8419.35
Dryers, for wood, paper pulp, paper or paperboard, not used for domestic purposes.
Classification of wood dryer under HS 8419.35
The classification of a wood dryer under HS code 8419.35 is based on the machine's primary function of moisture removal through thermal treatment. Heading 8419 covers machinery and plant equipment for the treatment of materials by a process involving a change of temperature, such as heating, cooking, roasting, or drying. Subheading 8419.35 is specifically allocated to dryers used for wood, paper pulp, paper, or paperboard. These are industrial-scale units used in sawmills and timber processing facilities to reduce the moisture content of lumber, veneers, or wood chips to prevent warping and decay. The classification is determined by the fact that the machine is not for domestic use and is specifically engineered for the physical properties of wood and wood-based fibers.

Codes often confused with 8419.35
Common mistake. Wood dryers are often confused with HS code 8451.21 or 8451.29, which cover drying machines for textiles or laundry. While both remove moisture, the engineering and application are entirely different. Another common misclassification is 8419.39, which is the residual category for "other" industrial dryers. Because the HS system provides a specific subheading (8419.35) for wood and paper dryers, using the general category 8419.39 is a classification error. Additionally, small domestic-use dryers are classified in Chapter 85.

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).
