Product classification
HS code for Digital wall clocks: 9105.21
Clocks, (excluding those with watch movements and instrument panel clocks), wall clocks, electrically operated.
Classification of digital wall clocks under HS 9105.21
Digital wall clocks are classified under HS code 9105.21. This classification is situated within Chapter 91, which covers clocks, watches, and their parts. Heading 9105 is reserved for "Other clocks," a category that excludes clocks with watch movements (which are found in 9103). The subheading 9105.21 specifically identifies wall clocks that are electrically operated. To qualify for this code, the clock must be designed primarily for mounting on a wall and must utilize an electrical power source, such as a battery or a mains connection. The "digital" aspect refers to the opto-electronic display (LCD, LED, or VFD) used to show the time, which distinguishes it from analog clocks with mechanical hands. The classification is determined by the combination of the mounting style (wall) and the method of operation (electrical/electronic).

Codes often confused with 9105.21
Common mistake. Digital wall clocks are frequently confused with 9105.11, which is the code for alarm clocks. If a clock has an alarm function but is designed to sit on a desk or bedside table, it belongs in 9105.11. If it is a wall-mounted clock with an alarm, the wall-mounting characteristic usually dictates classification in 9105.21. Another misclassification occurs with 9103.10, which covers clocks with watch movements; however, most digital wall clocks do not use movements that meet the size and thickness definitions of a "watch movement" as defined in Note 3 to Chapter 91.
Top exporters and importers of HS 910521 (the code used for digital wall clocks), 2025
In 2025, the largest exporter of HS 910521 (the code used for digital 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).
