Chapter 91 covers clocks and watches and their parts, including personal clocks and watches, instrument panel clocks, vehicle clocks, aircraft clocks, ship clocks and other timekeeping devices, as well as clock and watch movements, parts and accessories. This chapter does not include timekeeping devices specifically named in other chapters, such as time recorders of Chapter 85 or time measuring instruments of Chapter 90. The core feature is use for measuring, indicating or recording time, and they are usually mechanical or electronic timekeeping devices. Heading 9106 covers time recorders and apparatus for measuring, recording or otherwise indicating intervals of time, with clock or watch movement or with synchronous motor (for example, time recorders, time-stamp machines), but excludes clocks and watches of headings 9101 to 9105. This heading includes vehicle timers, parking meters, race timers, production timers and other industrial or special-purpose timing equipment whose core function is to record or indicate intervals of time rather than merely display the current time. First 2 digits 91: Chapter 91, clocks and watches and their parts. Digits 3-4: 06: heading 9106, time recorders and apparatus for measuring, recording or otherwise indicating intervals of time, with clock or watch movement or with synchronous motor. Digits 5-6: 90: subheading 910690, other time recorders and apparatus for measuring, recording or otherwise indicating intervals of time. This subheading is a residual subheading covering other similar apparatus not specifically named in 910610 (time recorders) and 910620 (parking meters), such as vehicle timers, industrial timers, sports timers, etc. Vehicle timers are used to record or indicate intervals of vehicle operating time and are usually fitted with an electronic or mechanical clock or watch movement, meeting the definition of heading 9106 as "apparatus for measuring, recording or otherwise indicating intervals of time." They are not classified in 9105 (other clocks) because their main function is not to display the current time; not in 8708 (motor vehicle parts) because their core function is timing rather than being a mechanical vehicle component; and not in 8531 (electric signalling apparatus) because they do not involve sound or light signals.

Product name: The standard name of the declared commodity, which should accurately reflect the function of the goods, such as "vehicle timer" or "vehicle time recorder." Use: Explain the specific use scenario of the commodity, such as "installed on commercial vehicles to record driving time" or "used for timing engineering vehicles." Working principle: Explain the timing method, such as "electronic oscillator timing," "mechanical clock or watch movement," or "synchronous motor drive." Brand: Fill in the brand of the commodity; if there is no brand, write "no brand." Model: Fill in the specific model or specification for easy identification. Whether fitted with clock or watch movement: Clearly state whether it is fitted with a clock or watch movement or synchronous motor, which is key to classification under 9106. Display method: State whether it is digital display, pointer display, or no display (recording only). Product name: vehicle timer; Use: installed on commercial vehicles to record engine operating time; Working principle: electronic oscillator timing, fitted with a quartz clock or watch movement; Brand: XX; Model: T-100; Whether fitted with clock or watch movement: Yes; Display method: digital display. Mistakenly classifying a vehicle timer under 8708 motor vehicle parts, ignoring its core timing function. Failure to declare "whether fitted with clock or watch movement," making it impossible to determine classification under 9106. Mistakenly reporting a device that only records intervals of time as a vehicle clock that displays the current time (which should be classified under 9105).

Core basis for classification: whether the commodity is fitted with a clock or watch movement or synchronous motor, and whether its main function is to measure, record or indicate intervals of time. Vehicle timers are usually installed in vehicles to record operating time or intervals of time, meeting the wording of heading 9106. If they only display the current time, they are classified under 9105; if they are mechanical vehicle components (such as speed sensors), they are classified under 8708; if they are electric signalling apparatus, they are classified under 8531. 9105 Other clocks: 9105 covers clocks that display the current time, such as vehicle clocks; 9106 covers apparatus for measuring, recording or otherwise indicating intervals of time, such as vehicle timers. The core difference is whether the function is to display the time or to time. 8708 Motor vehicle parts and accessories: 8708 covers mechanical or electrical vehicle parts, such as instrument panels and sensors; if a vehicle timer is an independent timing device, it should be classified under 9106 rather than as a vehicle part. 8531 Electric signalling apparatus: 8531 covers signalling apparatus such as electric bells and indicator lights; if a vehicle timer only records time and has no signalling function, it should be classified under 9106. 9029 Revolution counters, production counters: 9029 covers revolution counters, production counters, etc., which are usually not fitted with clock or watch movements; if a vehicle timer is fitted with a clock or watch movement, it should be classified under 9106. Is the commodity fitted with a clock or watch movement or synchronous motor? Is its main function to measure, record or indicate intervals of time? Is it used for vehicles but independent of the vehicle mechanical system? Is it not classified under clocks and watches of 9101-9105? Is it not classified under adjacent headings such as 8708, 8531, 9029?

What is the difference between a vehicle timer and a vehicle clock? A vehicle timer is used to record or indicate intervals of time (such as engine operating time) and is usually classified under 9106; a vehicle clock is used to display the current time and is classified under 9105. The difference lies in whether the core function is timing or displaying the time. How can it be determined whether a vehicle timer should be classified under 9106? The key is whether it is fitted with a clock or watch movement or synchronous motor and whether its main function is to measure, record or indicate intervals of time. If it only displays the current time, it is classified under 9105; if it is a mechanical vehicle component, it is classified under 8708. What elements must be provided when declaring a vehicle timer? Product name, use, working principle, brand, model, whether fitted with clock or watch movement, display method, etc. must be provided. Among these, "whether fitted with clock or watch movement" is the key element for classification under 9106. How should a vehicle timer with GPS function be classified? If GPS only assists timing and the core function is still time recording, it is classified under 9106; if GPS is the main function, it may be classified under 8526 (radar and radio navigational aid apparatus). It must be judged according to the main function. What is the difference between subheading 910690 and 910610, 910620? 910610 is time recorders, 910620 is parking meters, and 910690 is other time recorders and apparatus for measuring, recording or otherwise indicating intervals of time. Vehicle timers are usually classified under 910690. After a vehicle timer is classified under 9106, how can the tax rate be checked? The tax rate must be checked according to the customs tariff of the destination country/region, usually by using the HS code on an official tariff website or by consulting a customs broker. Note that tax rates change, and the latest tariff shall prevail. If a vehicle timer is an original equipment part of a vehicle, must it be classified under 8708? Not necessarily. If the timer works independently and its core function is timing, it should still be classified under 9106. 8708 applies to mechanical or electrical vehicle parts, not independent timing devices. How can cross-border e-commerce sellers of vehicle timers ensure correct classification? It is recommended to check the product manual to confirm whether it is fitted with a clock or watch movement and whether the main function is timing. Reference may be made to customs classification decisions or a professional customs broker may be consulted to avoid customs clearance delays caused by incorrect classification.
