Harmonized System Code Classification

The first two digits of the HS code "91" represent "Clocks and other measuring instruments."

Specifically, this classification includes the following:

• Clocks: Including various types of clocks such as mechanical clocks, electronic clocks, wristwatches, mantel clocks, and wall clocks.
• Timing instruments: Covering stopwatches, timers, and alarm clocks.
• Measuring instruments: Including devices used for measuring, indicating, recording, or controlling various physical quantities (such as length, weight, temperature, angle, pressure, etc.).
• Counters: Including various types of counters such as mechanical counters and electronic counters.
• Other related instruments: Including instruments used for calibrating, testing, or maintaining the aforementioned instruments.

In short, the HS code 91 mainly refers to goods related to time measurement, counting, and measurement of physical quantities.

If you want to understand more detailed classifications, you can provide a more specific HS code (e.g., 9101), and I will explain based on the more detailed code.

The first four digits of the HS code "9101" represent the following classification:

Wristwatches, pocket watches, and other watches, including stopwatches, with cases made of precious metals or clad with precious metals.

6-digit explanation: HS code: 9101.21

8-10 digit explanation: HS code: 9101211000 Classification: Watches, including stopwatches, with cases made of precious metals or clad with precious metals --> Other watches, whether or not with a stopwatch function --> With automatic winding function --> With a movement containing more than 17 jewels --> Watch straps, bracelets, or chains imported together with watches under the tax number 9101.21.50, and according to the additional U.S. note 2 of this chapter, may be classified under this tax number; the aforementioned products, whether or not connected to these watches at the time of import: --> Made of textile materials or base metals, whether or not gold-plated or silver-plated

Explanation: This HS code corresponds to watches with an automatic winding function, a movement containing more than 17 jewels, watch straps, bracelets, or chains imported together with watches under the tax number 9101.21.50 or that can be classified under this tax number, and made of textile materials or base metals (whether or not gold-plated or silver-plated). It covers watches with cases made of precious metals or clad with precious metals, but specific classification depends on their automatic winding function, number of jewels, and the material of the watch strap/bracelet.
