Product classification
HS code for Manual wind clocks: 9103.90
Clocks, with watch movements, other than electrically operated, excluding clocks of heading no. 9104.
Classification of manual wind clocks under HS 9103.90
Manual wind clocks are classified under HS code 9103.90. This classification is based on the criteria set forth in Chapter 91 of the Harmonized System, which deals with clocks and watches and parts thereof. Heading 9103 specifically covers clocks with watch movements, excluding clocks of heading 9104 (instrument panel clocks). To qualify as having a "watch movement," the internal mechanism must meet the dimensions specified in Note 3 to Chapter 91: it must be no thicker than 12 mm and the width, length, or diameter must not exceed 50 mm. The subheading 9103.90 is the residual category for these clocks that are not electrically operated. Since manual wind clocks rely on a mechanical spring tensioned by a human turning a crown or key, they are excluded from the electrical subheadings and placed here.

Codes often confused with 9103.90
Common mistake. Manual wind clocks are often confused with HS code 9105.99, which covers "other" mechanical clocks. The distinction lies in the movement; if the movement exceeds the dimensions of a watch movement (12mm thickness or 50mm width), it must go to 9105. If it is smaller, it stays in 9103. Another error is using 9103.10, which is strictly for electrically operated clocks (battery or mains powered). Finally, if the clock is designed for a vehicle dashboard, it must be classified under 9104.00 regardless of the movement type.
Top exporters and importers of HS 910390 (the code used for manual wind clocks), 2025
In 2025, the largest exporter of HS 910390 (the code used for manual wind clocks) in UN Comtrade data was Switzerland, with 51% of world exports; the largest importer in UN Comtrade data was Switzerland, with 51% of world imports.

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).
