Product classification
HS code for Desk clocks: 9103.90
Clocks, with watch movements, other than electrically operated, excluding clocks of heading no. 9104.
Classification of desk clocks under HS 9103.90
Desk clocks that utilize watch movements and are not electrically operated are classified under HS code 9103.90. Chapter 91 of the Harmonized System covers clocks, watches, and parts thereof. Heading 9103 is specifically for clocks with watch movements, excluding instrument panel clocks. To be classified here, the clock must contain a "watch movement" as defined by Note 3 to Chapter 91. This means the movement must be regulated by a balance-wheel and hairspring, quartz crystal, or another system capable of determining time intervals, and it must not exceed 12mm in thickness or 50mm in width, length, or diameter. Subheading 9103.90 is the residual category for these clocks when they are not electrically operated, meaning they are typically mechanical and powered by a mainspring. These are often high-quality or vintage-style desk and table clocks. The classification relies on the technical specifications of the internal movement rather than the external appearance of the clock housing.

Codes often confused with 9103.90
Common mistake. The most common misclassification is with HS code 9103.10, which is for clocks with watch movements that are electrically operated (e.g., battery-powered). Another frequent error is using HS code 9105.21 or 9105.29, which are for wall clocks. If the clock does not have a "watch movement" (i.e., the movement is larger than 12mm thick or 50mm wide), it must be classified under heading 9105 as a standard clock. Specifically, mechanical clocks with larger clock movements fall under 9105.99. Distinguishing between a watch movement and a clock movement is the most critical step in this classification process.
Top exporters and importers of HS 910390 (the code used for desk clocks), 2025
In 2025, the largest exporter of HS 910390 (the code used for desk 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. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).

Questions about desk clocks
What is the HS code for Desk clocks?
The HS code for Desk clocks is 910390 (Clocks; with watch movements, other than electrically operated, excluding clocks of heading no. 9104). For mechanical desk clocks with watch movements, the HS code is 9103.90. If they are battery-operated, the code is 9103.10.
How do I classify Desk clocks for customs?
Desk clocks is classified under HS code 910390 — Clocks; with watch movements, other than electrically operated, excluding clocks of heading no. 9104. This is a 6-digit subheading level code.
How do I know if my clock has a watch movement?
A watch movement is defined by its size; it must be no thicker than 12mm and no wider/longer than 50mm. Most small, high-precision mechanical desk clocks meet these criteria.
Which countries are the top exporters of desk clocks (HS 910390)?
In 2025, the top exporters of HS 910390 (the code used for desk clocks) in UN Comtrade data were Switzerland ($27M, 51% of world exports), the United Kingdom ($11M) and France ($3.0M). World exports came to about $53M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
