Product classification
HS code for Quartz wall clocks: 9105.21
Clocks, (excluding those with watch movements and instrument panel clocks), wall clocks, electrically operated.
Classification of quartz wall clocks under HS 9105.21
Quartz wall clocks are classified under HS code 9105.21. This classification is situated within Chapter 91, which covers horological instruments. Heading 9105 is used for clocks that do not contain watch movements. According to Note 3 to Chapter 91, a watch movement is defined by its size and regulation mechanism; most wall clocks use larger movements that do not meet these specific dimensions. Subheading 9105.21 specifically identifies wall clocks that are electrically operated. This includes any wall-mounted timekeeping device powered by batteries, solar cells, or a connection to the electrical grid, utilizing a quartz crystal oscillator to regulate time. The classification is driven by the device's primary function as a fixed-location timekeeper and its electronic movement. Whether the clock has an analog face with hands or a digital liquid crystal display (LCD), it remains under 9105.21 as long as it is designed for wall mounting and is electrically powered.

Codes often confused with 9105.21
Common mistake. Quartz wall clocks are sometimes misclassified under 9103.10 if they are thought to contain a watch movement. However, 9103 is for clocks with watch movements, which are rare in standard wall clocks. Another common error is using 9105.91, which is for other electrically operated clocks. 9105.91 should only be used for clocks that are not wall-mounted, such as alarm clocks or desk clocks. If the clock is designed to be hung on a wall, 9105.21 is the mandatory code.
Top exporters and importers of HS 910521 (the code used for quartz wall clocks), 2025
In 2025, the largest exporter of HS 910521 (the code used for quartz wall clocks) in UN Comtrade data was China, with 73% of world exports; the largest importer in UN Comtrade data was the United States, with 13% 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).
