HS Code 91.06 – Time of day recording apparatus and apparatus for measuring, recording or otherwise indicating intervals of time, with clock, watch movement or synchronous motor

HS code 9106 is a 4-digit heading in the Harmonized System that covers: Time of day recording apparatus and apparatus for measuring, recording or otherwise indicating intervals of time, with clock, watch movement or synchronous motor. HS Heading 9106 covers "Time of day recording apparatus and apparatus for measuring, recording or otherwise indicating intervals of time, with clock, watch movement or synchronous motor." This classification is distinct from simple time-displaying clocks (9105) because its primary function involves the measurement, recording, or indication of specific time intervals or the precise time of an event. This heading encompasses a range of devices from employee attendance systems to industrial process timers and professional sports timing equipment. The essential characteristic is the active engagement with time beyond mere display, often involving data capture or event marking. The scope includes both mechanical and electronic devices, provided they incorporate a clock, watch movement, or synchronous motor to perform their time-related functions. Key sub-categories include time clocks (punch clocks), parking meters, elapsed time indicators, and specialized chronographs for scientific or industrial applications. For trade compliance professionals, correctly identifying whether a device merely displays time or actively records/measures it is paramount, as misclassification can lead to significant duty discrepancies and regulatory non-compliance. This heading is crucial for industries reliant on precise time management, such as manufacturing, human resources, and event management. As part of Section XVIII, it emphasizes the precision and functional aspects of horological instruments that serve specific, advanced purposes beyond basic timekeeping.

Employee time clocks (punch clocks), electronic attendance recorders, smart parking meters (with time recording), industrial elapsed time indicators, time-stamping machines (for documents), professional sports timing systems, laboratory experiment timers, production line timers, digital stopwatches (with memory/recording), time-recording modules for access control, automated event timers, data loggers with time-stamping, vehicle usage time recorders, process control timers with recording, digital chronographs (industrial grade), time-and-date stampers, time-tracking devices for fieldwork, machinery run-time recorders, security guard tour clocks, hospital patient interval timers, racing event finish line timers, judicial court time recorders, broadcast segment timers, energy consumption interval meters.

A frequent misclassification under HS 9106 occurs when traders confuse time-recording apparatus with simple clocks. If a device merely displays time without recording, measuring intervals, or stamping, it typically falls under 9105 ('Clocks, other, n.e.c.'). Another error is classifying complex electronic systems where time recording is a secondary feature under this heading, instead of more specific electronics categories like 8543 ('Electrical machines and apparatus, having individual functions') or 8537 ('Boards, panels, consoles for electric control'). Additionally, devices primarily designed as revolution counters or production counters, even if they have a time element, might be incorrectly placed here instead of 9029. The key differentiator is the primary function of actively measuring, recording, or indicating intervals of time, rather than just passively displaying the current time.

In 2025, the top exporters of HS code 9106 in UN Comtrade data were China ($465M, 67% of world exports), France ($50M) and the Netherlands ($25M). World exports came to about $693M, 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.

In 2025, the top importers of HS code 9106 in UN Comtrade data were Russia (about $331M, 55% of world imports), Japan ($24M) and Germany ($24M). World imports came to about $605M, 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.

HS code 9106 is a 4-digit heading under Chapter 91 of the Harmonized System. The first 2 digits (91) identify the chapter, and digits 3-4 (06) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
