Chapter 91 covers clocks and watches and their parts, including various types of wristwatches, pocket watches, clocks, timers, time recorders, and their movements and components. The core characteristic of this chapter is that the goods must have a timekeeping function and are usually driven mechanically or electronically. It should be noted that this chapter does not include instruments for measuring, recording, or indicating time intervals (such as stopwatches and timers) if they are mainly used for other purposes, nor does it include toy clocks and watches (Chapter 95) or jewelry watches made of precious metal (Chapter 71). Heading 9102 covers other wristwatches, pocket watches, and other watches, including stopwatches, but excludes watches made of precious metal or rolled precious metal of heading 9101. Specifically, it includes: wristwatches, pocket watches, and stopwatches with only a time display function; wristwatches with a timer function; and wristwatches combining other functions (such as calculators and radios). However, it does not include smartwatches (usually classified under 8517 or 8471) or vehicle clocks (classified under 9105). The first 2 digits, 91: indicates Chapter 91, namely clocks and watches and their parts. Digits 3-4, 02: indicates heading 9102, namely other wristwatches, pocket watches, and other watches, including stopwatches, but excluding watches made of precious metal or rolled precious metal of heading 9101. Digits 5-6, 21: indicates subheading 9102.21, namely other wristwatches with a mechanical display only, and self-winding. Self-winding means the watch is automatically wound by the wearer's movement or an internal rotor, without the need to manually turn the crown. Watches under this subheading are usually mechanical automatic watches, distinguished from manually wound (9102.11) and electronic watches (9102.12). This product is a car-use automatic watch. Its core function is timekeeping, and it uses a self-winding mechanical movement, so it is classified under 9102.21. It is different from vehicle clocks (9105), because vehicle clocks are usually fixed installations and do not have a wearable function; it is also different from precious metal watches (9101), because its material is not precious metal; and it is further different from smartwatches (8517), because it does not have communication or data processing functions.

Brand: Enter the watch brand name, such as "Rolex", "Seiko", etc. It must be consistent with the actual item or packaging. Model: Enter the specific model or item number of the watch, such as "SARB033". Movement Type: State "self-winding mechanical" or "manual-winding mechanical" or "electronic". Case Material: Enter the case material, such as "stainless steel", "titanium alloy", "plastic", etc. Strap Material: Enter the strap material, such as "leather", "stainless steel", "rubber", etc. Is It Made of Precious Metal: State "yes" or "no". If it is made of precious metal, it must be classified under 9101. Function: State the main function, such as "timekeeping only", "chronograph", "with calendar", etc. Brand: SEIKO; Model: SARB033; Movement Type: self-winding mechanical; Case Material: stainless steel; Strap Material: leather; Is It Made of Precious Metal: no; Function: timekeeping only (hours, minutes, seconds). Mistakenly declaring a self-winding mechanical watch as an electronic watch, resulting in incorrect classification. Ignoring precious metal components in the case material, which may mean it should be classified under 9101. Confusing a car-use watch with a vehicle clock and incorrectly classifying it under 9105.

The core basis for classification is: 1. Whether the product is a watch (with a wearable or carryable function); 2. Whether the movement type is self-winding mechanical; 3. Whether it has only a mechanical display; 4. Whether it excludes precious metal watches (9101) and smartwatches (8517). If a car-use automatic watch has a wearable function and is self-winding mechanical, it is classified under 9102.21. 9101 Watches made of precious metal or rolled precious metal: 9101 applies to watches whose cases are made of precious metal or rolled precious metal, while 9102.21 applies to self-winding mechanical watches made of other materials (such as stainless steel). 9102.11 Manual-winding mechanical watches: 9102.11 is manual-winding and requires manually turning the crown to wind; 9102.21 is self-winding and winds automatically through a rotor. 9102.12 Electronic watches: 9102.12 has an electronic movement (such as quartz, LED, LCD), while 9102.21 has a mechanical movement. 9105 Vehicle clocks: 9105 refers to clocks for vehicles, aircraft, or vessels, usually fixed installations and without a wearable function; 9102.21 refers to wearable watches. 8517 Smartwatches: 8517 refers to smartwatches with communication or data processing functions, while 9102.21 is only for timekeeping functions. Is the watch a self-winding mechanical watch? Is the case made of non-precious metal? Does it have only a timekeeping function? Does it have a wearable or carryable function? Are smartwatches and vehicle clocks excluded?

Is there a difference in HS code between a car-use automatic watch and an ordinary automatic watch? No difference. As long as the watch is a self-winding mechanical watch and is not made of precious metal, it is classified under 9102.21. The car-use feature does not affect classification unless it is fixed-installed in a vehicle and does not have a wearable function, in which case it may be classified under 9105. How can one determine whether a watch is self-winding mechanical? A self-winding mechanical watch usually has a rotor, which can be determined by observing the back of the watch or by shaking it and listening for a sound. When declaring, proof of movement type must be provided, such as a product manual or test report. If the watch case is gold-plated, which code should it be classified under? A gold-plated case is not considered precious metal and is still classified under 9102.21. Only cases made of precious metal or rolled precious metal (such as gold, silver, platinum) are classified under 9101. Can a smartwatch be classified under 9102.21? No. Smartwatches usually have communication, data processing, and other functions, and should be classified under 8517.62 or other corresponding codes. 9102.21 applies only to purely timekeeping mechanical watches. How should "Brand" and "Model" be filled in during customs declaration? For Brand, enter the watch brand; for Model, enter the specific model. If it is an unbranded watch, "no brand" may be entered, but other identifiers must be provided. The model must be consistent with the actual item. What is the tariff rate for 9102.21? Tariff rates vary by country, trade agreement, and country of origin. It is recommended to consult the Chinese Customs Import and Export Tariff or use a customs classification query tool to obtain the latest rate. If the watch has a calendar function, will it affect classification? No. The calendar function is an additional function. As long as the main function is timekeeping and the movement is self-winding mechanical, it is still classified under 9102.21. How can one check the regulatory conditions for 9102.21? The regulatory conditions for this code, such as whether commodity inspection or licenses are required, can be checked through the website of the General Administration of Customs of China or the "Single Window." A professional customs broker can also be consulted.
