Clocks; movements, whether or not complete, incomplete, assembled or unassembled
HS v2022 Code: 911090
About clocks; movements, whether or not complete, incomplete, assembled or unassembled
HS code 911090 covers a wide range of clock movements, both complete and incomplete, assembled or unassembled. This industry plays a crucial role in the broader timepiece and precision instruments sector, which is an important component of the global manufacturing economy. Clock movements are the heart of timepieces, enabling the accurate measurement and display of time, and find applications in a diverse range of products from wristwatches to industrial control systems.
Production process
The production of clock movements typically involves a series of precision engineering processes. Key steps include the fabrication of individual components such as gears, springs, and escapement mechanisms, followed by careful assembly and adjustment to ensure accurate timekeeping. Advanced manufacturing techniques like computer numerical control (CNC) machining and automated assembly lines are commonly employed to achieve the tight tolerances and quality standards required in this industry.
Production inputs
The main inputs for the clock movements industry include a variety of metals, such as brass, steel, and jewel bearings, as well as specialized components like quartz crystals, electronic circuits, and battery power sources. Highly skilled labor, specialized machinery, and precise measurement tools are also essential inputs for this industry.
Production outputs
The primary outputs of the clock movements industry are the various types of clock and watch movements, which are then incorporated into a wide range of final products. These include 9101 Wristwatches, pocket-watches and other watches, including stop-watches, 9102 Clocks with watch movements, excluding clocks of heading 9101, and 9104 Instrument panel clocks and clocks of a similar type for vehicles, aircraft, spacecraft or vessels.
