HS Code 91 – Clocks and watches and parts thereof
What HS 91 covers
Chapter 91 of the Harmonized System (HS) meticulously categorizes "Clocks and watches and parts thereof," serving as the definitive classification for all timekeeping instruments and their components in international trade. This chapter encompasses a vast array of devices designed to measure, indicate, or record time, ranging from intricate mechanical masterpieces to advanced electronic gadgets. Its scope extends to wristwatches, pocket watches, clocks of all types (wall, table, alarm, tower), time-registers, time switches, and chronometers. Crucially, it also covers the specialized movements (assemblies of parts that make the timekeeping function possible) and all identifiable parts suitable solely or principally for use with these articles, such as cases, dials, hands, springs, and integrated circuits for electronic movements. The boundaries of Chapter 91 are precise, distinguishing dedicated timekeeping devices from other instruments that might incidentally display time but have a primary function elsewhere (e.g., smartwatches with extensive computing capabilities might fall under Chapter 85 or 84, depending on the principal function, or certain vehicle dashboard instruments in Chapter 90). This classification is vital for trade compliance as it dictates applicable customs duties, import/export regulations, origin rules, and potential eligibility for preferential trade agreements. The historical significance of timekeeping, particularly the Swiss watch industry, underlines the high value and precision associated with many goods in this chapter. Major headings within Chapter 91 include watches (9101-9102), clocks (9103-9105), time-recording devices (9106), time switches (9107), watch movements (9108), clock movements (9109), and a comprehensive range of watch and clock parts (9110-9114), ensuring a granular classification for every component of the horological world.

1. A renowned Swiss luxury watch manufacturer, Patek Philippe, exports a consignment of high-complication automatic wristwatches (HS 9101.21) from Geneva, Switzerland, to authorized dealers in New York, USA, and Hong Kong, SAR. These high-value shipments typically travel via air freight, requiring meticulous customs declarations to ensure proper valuation and duty calculation, often benefiting from preferential treatment under specific trade agreements if applicable. 2. A Chinese electronics company, producing mass-market digital alarm clocks (HS 9105.11) and wall clocks (HS 9105.91), ships several containers monthly from Shenzhen, China, to major retailers and distribution centers across Europe (e.g., Germany, France) via ocean freight. The sheer volume and competitive pricing necessitate efficient customs clearance and adherence to EU import regulations, including CE marking and RoHS compliance. 3. A Japanese precision manufacturer, Seiko Instruments, exports thousands of quartz watch movements (HS 9108.12) to watch assembly factories in Thailand and Malaysia. These movements are critical components for the final assembly of mid-range watches. The shipments are usually air freighted to maintain supply chain efficiency, and the importing countries often have reduced duties on such components to support their domestic manufacturing industries. 4. A German artisan workshop specializing in traditional cuckoo clocks (HS 9105.21) exports handcrafted pieces to specialty gift shops and tourist markets in the United States and Canada. These unique items, often made of wood, are carefully packaged and shipped via express courier or air freight, requiring precise classification to avoid delays and ensure the cultural heritage aspect is recognized for customs purposes.

Codes often confused with 91
Common mistake. Common classification errors in Chapter 91 often arise from the blurred lines between dedicated timekeeping and multi-functional devices. A frequent mistake is classifying advanced smartwatches or fitness trackers under Chapter 91 (e.g., 9102), when their primary function, due to extensive computing, communication, or data processing capabilities, leans towards Chapter 85 (e.g., 8517 for telecommunication apparatus or 8543 for electrical machines with individual functions). Similarly, certain timers or display units for industrial machinery might be mistakenly placed in Chapter 91, but if they are integral parts of a larger machine and not standalone timekeepers, they could belong to Chapter 84 (machinery) or Chapter 85 (electrical machinery). Another pitfall is with clocks incorporated into furniture; while the clock mechanism itself is Chapter 91, if it's an inseparable part of a piece of furniture (e.g., a grandfather clock where the case is primary), the entire item might fall under Chapter 94 (furniture). Careful consideration of the principal function and the "parts" rule is crucial to avoid these errors.
Top exporters and importers of HS code 91, 2025
In 2025, the largest exporter of HS code 91 in UN Comtrade data was Switzerland, with 49% of world exports; the largest importer in UN Comtrade data was Hong Kong, with 14% 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).
