HS Code 9103.90 – Clocks; with watch movements, other than electrically operated, excluding clocks of heading no. 9104
HS code 9103.90 is the 6-digit subheading for clocks, with watch movements, other than electrically operated, excluding clocks of heading no. 9104. It is used for mechanical desk clocks, wind-up mantel clocks, pendulum clocks with watch movements, skeleton clocks and carriage clocks.
What HS 9103.90 covers
This HS code pertains to clocks that utilize traditional 'watch movements' but are not electrically operated, and are not for vehicles (9104). These are typically mechanical clocks, often requiring winding, and are prized for their craftsmanship, intricate gear trains, and classic aesthetic. The trade in these items is often driven by luxury markets, antique reproductions, and specialty horology shops. Exporters are typically countries with a strong heritage in mechanical clockmaking, while importers include collectors, high-end home decor retailers, and gift markets. The value lies in their mechanical complexity, the absence of electrical components, and their often timeless design, appealing to those who appreciate traditional timekeeping.

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).
