Classification of office chair under HS 9401.39
Office chairs are classified under HS code 9401.39. This classification is found within Chapter 94, which covers furniture, bedding, and similar products. Specifically, heading 9401 covers seats (other than those of heading 9402), whether or not convertible into beds, and their parts. The sub-heading 9401.30 is dedicated to swivel seats with variable height adjustment. Within this sub-heading, 9401.31 is for seats with wooden frames, while 9401.39 is for seats with frames made of other materials, typically metal or plastic. To be classified here, the chair must feature a mechanism that allows it to rotate 360 degrees and a system (such as a gas cylinder or screw) to adjust the height of the seat. These features are characteristic of modern ergonomic office furniture. The material of the upholstery, whether leather, textile, or synthetic mesh, does not affect the primary classification as long as the frame is not wood and the swivel/height adjustment features are present.

Codes often confused with 9401.39
Common mistake. Office chairs are frequently misclassified under 9401.31 if the customs broker fails to identify the frame material correctly (wood vs. metal). They are also sometimes confused with 9401.71 or 9401.79, which cover other seats with metal frames but lack the swivel and height adjustment features. Additionally, specialized medical or dental chairs must be classified under 9402.10, even if they swivel, as they are designed for specific professional procedures.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
