Chapter 91 covers clocks and watches and their parts, including timepieces, movements, cases, clock cases, and other clock and watch parts. This chapter is divided into two main parts: complete clocks and watches (headings 91.01 to 91.05) and clock and watch movements and parts (headings 91.06 to 91.14). Vehicle automatic movements, as a type of clock and watch movement, fall within the parts category of this chapter, but due to their special use and structure, they are specifically named at the subheading level. Heading 91.08 covers clock and watch movements, including assembled and unassembled movements, for clocks or watches. This heading is further subdivided into electronic movements, mechanical movements, and other subheadings. Vehicle automatic movements usually refer to self-winding mechanical movements used for vehicle instrument panels or dedicated vehicle clocks, characterized by automatically winding using the kinetic energy generated by vehicle motion, without manual operation. Code 910820 has 6 digits: the first 2 digits "91" represent Chapter 91 (clocks and watches and their parts); digits 3-4 "08" represent heading 91.08 (clock and watch movements); digits 5-6 "20" represent subheading 9108.20, i.e., "automatic winding movements". Automatic winding movements automatically wind through devices such as oscillating weights, differing from manual winding movements (9108.11) and other electronic movements. Although vehicle automatic movements are used in vehicles, they are still classified under the automatic winding movement subheading according to movement type, unless they constitute complete vehicle parts. Vehicle automatic movements are classified under 910820 because their core function is as clock and watch movements, and they are of the automatic winding type. They should not be classified under 8708 (vehicle parts), because their essence is a timekeeping device rather than an essential component for vehicle operation; nor should they be classified under other subheadings of 9108, such as 9108.11 (manual winding) or 9108.90 (other), because they have an automatic winding mechanism.

Product Name: Should be declared as "vehicle automatic movement" or "automatic winding movement for automobile clocks", clearly specifying the use and movement type. Brand: Fill in the movement brand, such as Seiko, Citizen, etc.; if no brand, fill in "unbranded". Model: Fill in the specific model or number of the movement for easy identification. Working Principle: State that it is an automatic winding mechanical movement, automatically winding using vehicle motion. Automatic Winding: Clearly declare as automatic winding, distinguishing from manual winding. Use: Declare as dedicated for vehicle clocks, installed on vehicle instrument panels, etc. Size: Fill in the movement diameter or dimensions, expressed in millimeters. Origin: Fill in the country or region of origin of the movement. Product Name: Vehicle automatic movement; Brand: SEIKO; Model: 6650; Working Principle: Automatic winding mechanical movement, automatically winding using vehicle motion; Automatic Winding: Yes; Use: Dedicated for vehicle clocks; Size: Diameter 50mm; Origin: Japan. Mistakenly classifying vehicle automatic movements under 8708 vehicle parts, ignoring their essence as clock and watch movements. Failing to declare the "automatic winding" element, leading to subheading classification errors under 9108.11 or 9108.90. Confusing movements with complete clocks and watches, mistakenly classifying under 9105 or other complete clock and watch headings.

The core basis for classification is Chapter 91 and its notes of the "Import and Export Tariff". Vehicle automatic movements belong to clock and watch movements, have an automatic winding mechanism, and are used for vehicle timekeeping. According to General Rules of Interpretation 1 and 6, they should be classified under subheading 9108.20 under heading 91.08. If the movement is combined with other vehicle components to form a complete vehicle part, it may be classified as a vehicle part, but movements imported separately are still classified as clock and watch movements. 910811 Manual winding movements: Manual winding requires manually rotating the crown to wind, while automatic winding uses an oscillating weight to wind automatically; the mechanisms are different. 910890 Other clock and watch movements: Includes electronic movements, quartz movements, etc., which are not mechanical automatic winding and have different working principles. 870829 Vehicle parts: Vehicle parts are essential components for vehicle operation, while vehicle automatic movements are independent timekeeping devices and are not essential for operation. 910519 Other clocks: Complete clocks and watches are already assembled, while movements are unassembled or semi-finished products requiring further installation. Is it an automatic winding mechanical movement? Is it dedicated for vehicle timekeeping? Is it imported separately rather than combined with a vehicle? Does it have the basic characteristics of a clock and watch movement? Is it possible to classify it as a vehicle part?

Is there a difference in HS code between vehicle automatic movements and ordinary automatic movements? No difference. HS code 910820 covers all automatic winding movements, regardless of whether they are for vehicles. Vehicle use does not affect subheading classification, but the use must be indicated when declaring. How to determine whether a vehicle automatic movement should be classified as a vehicle part? If the movement is combined with other vehicle components into an inseparable whole and becomes an essential component for vehicle operation, it may be classified as a vehicle part. Movements imported separately are still classified under 910820. Why is the "automatic winding" element important when declaring? Automatic winding is the key to distinguishing 910820 from 910811. Failure to declare may lead to classification errors, affecting tariffs and regulatory conditions. How to inquire about the tariff rate for vehicle automatic movements? You can consult the "Import and Export Tariff" or the website of the General Administration of Customs, and query the MFN rate, general rate, etc., according to code 910820. Tariff rates may change, subject to the latest announcement. What regulatory documents are required for importing vehicle automatic movements? Usually no special regulatory documents are required, but basic documents such as contracts, invoices, and packing lists must be provided. Specific requirements are subject to customs. If the movement has electronic components, is it still classified under 910820? If the movement is an automatic winding mechanical movement, even with a small number of electronic components (such as lighting), it is still classified under 910820. If it is an electronic movement, it is classified under other subheadings. How is the origin of a vehicle automatic movement determined? According to the "Regulations on Origin", the origin is the country or region where the movement last underwent substantial transformation. Usually, it is the place where the movement was assembled.
