HS code for Automatic watches: 9102.21
Wrist-watches, whether or not incorporating a stop-watch facility, with automatic winding.
Classification of automatic watches under HS 9102.21
Automatic watches are classified under HS code 910221. This specific classification applies to wrist-watches that incorporate an automatic winding mechanism, meaning they are self-winding through the motion of the wearer. The description also notes that these watches may or may not include a stop-watch facility (chronograph function). The essential criteria for this classification are that the item is a complete wrist-watch, not just a movement, and its power source relies on an automatic mechanical winding system rather than manual winding or electrical operation.

Codes often confused with 9102.21
Common mistake. Automatic watches can be commonly misclassified with other types of wrist-watches. HS code 910211 covers wrist-watches with electrical operation, often with no mechanical display only. The key difference is the power source: automatic mechanical winding for 910221 versus electrical (battery-powered) for 910211. Another point of confusion can be with 910229, which encompasses other wrist-watches not specifically provided for, such as manual-winding mechanical watches. The defining characteristic for 910221 is the automatic winding feature. Furthermore, it is crucial to distinguish complete automatic watches from automatic watch movements (HS 910820), as the latter refers only to the internal mechanism.

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).
