Seats, swivel with variable height adjustment of wood, excluding medical, surgical, dental, veterinary or barber furniture.
Classification of wooden office chair under HS 9401.31
The classification of a wooden office chair falls under HS code 9401.31. Chapter 94 covers furniture, bedding, and similar furnishings. Heading 9401 is specifically designated for seats, whether or not convertible into beds, and their parts. The subheading 9401.31 is reserved for swivel seats with variable height adjustment that are primarily constructed with a wooden frame or base. This classification follows GRI 1 and GRI 6. The "swivel" and "variable height" features are the defining technical characteristics that separate office-style chairs from standard household dining chairs. Even if the chair has upholstery, if the structural frame and the swivel mechanism are integrated into a wooden design, 9401.31 is the appropriate code. It is important to note that this code excludes medical or dental chairs, which are classified under 9402. The distinction between 9401.31 (wooden) and 9401.39 (other materials like metal or plastic) is strictly based on the material of the supporting frame. For international trade, ensuring the chair meets the definition of "swivel" (rotating 360 degrees) and "variable height" (adjustable via gas lift or screw mechanism) is essential for correct duty application.

Codes often confused with 9401.31
Common mistake. Wooden office chairs are often misclassified under 9401.61 or 9401.69. These codes are for "Other seats, with wooden frames," but they specifically apply to seats that do not have swivel or height adjustment features. If a wooden chair is stationary, it belongs in 9401.61 (upholstered) or 9401.69 (not upholstered). Additionally, if the chair is made primarily of metal but has wooden armrests, it should be classified under 9401.39 (Other swivel seats) because the essential character is usually defined by the metal mechanism and frame.

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).
