HS code for Swivel chair (wooden): 9401.31
Seats, swivel with variable height adjustment of wood, excluding medical, surgical, dental, veterinary or barber furniture.
Classification of swivel chair (wooden) under HS 9401.31
The classification for wooden swivel chairs falls under HS code 9401.31. This code is specifically designated for seats that possess a swivel mechanism and variable height adjustment features, where the predominant material of the frame is wood. In the context of international trade, the material of the frame is a primary factor in determining the correct subheading within heading 9401. Wooden swivel chairs are often found in executive offices or home studies and are distinguished from their metal or plastic counterparts by the aesthetic and structural use of timber. The classification process involves identifying the core functionality—the ability to rotate 360 degrees and change height—and then applying the material-specific criteria. This follows General Interpretative Rule 1 and 6. If a chair has a wooden seat and back but a metal base, the classification often depends on which material gives the item its essential character; however, the Harmonized System specifically provides for wooden swivel seats under 9401.31 to differentiate them from the broader category of metal or plastic office furniture. This code excludes chairs intended for medical or dental use, which are classified under heading 9402.

Codes often confused with 9401.31
Common mistake. Wooden swivel chairs are frequently misclassified under HS code 9401.39, which is the catch-all for swivel seats made of other materials like metal or plastic. Another common error is using HS code 9403.30, which covers wooden office furniture in general; however, because heading 9401 specifically covers seats, it takes precedence over the more general furniture heading 9403. Importers must ensure the swivel and height adjustment features are present to use 9401.31.

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).
