The Harmonized System (HS) code for a level control switch can vary depending on its primary function and how it operates within a system. Generally, level control switches are classified under two main HS code categories, reflecting whether they are primarily considered an electrical switch or an automatic regulating instrument.
Common HS Codes for Level Control Switches
Level control switches can be classified under the following HS codes:
| HS Code | Product Description / Category | Typical Application and Characteristics |
|---|---|---|
| 8536 | Electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits (e.g., switches, relays, fuses, plugs, sockets, lamp-holders) | This broader chapter covers various types of electrical switches. A level control switch primarily functioning as an on/off electrical switch, activated by a fluid level, would fall here. |
| 853650 | Other switches: (within Chapter 8536) | This sub-heading is for switches that do not fit into more specific categories like push-button or rotary switches. Many basic level control switches, acting as simple electrical contacts, are classified here. |
| 85365090 | Other (within 853650) | This is a more specific classification for miscellaneous switches. If the level control switch's main role is to open or close an electrical circuit based on level, without advanced regulating capabilities, this code is often applicable. |
| 9032 | Automatic regulating or controlling instruments and apparatus | This chapter covers instruments and apparatus for automatically controlling or regulating variables like flow, level, pressure, temperature, etc. If the level control switch is integrated into, or functions as, an automatic control loop beyond simple on/off switching, it may be classified here. |
| 903289 | Other (within 9032 for automatic regulating or controlling instruments) | This specific sub-heading is used for other automatic regulating or controlling instruments that do not fall into more specific categories (e.g., thermostats, pressostats). Level control switches that provide feedback for automated systems, or have integrated control functions, can fall under this code. |
8536 - Electrical Switches
This category applies when the level control switch is primarily an electrical switching device. Its main function is to open or close an electrical circuit based on a detected liquid or material level. These switches typically have a simple on/off action and are used to start or stop pumps, activate alarms, or control valves directly. For example, a float switch that turns a pump on when water reaches a certain level is often classified under this heading. The HS code 853650 covers "Other switches," with 85365090 being a common specific sub-category for various types of level switches that fall under this description.
9032 - Automatic Regulating or Controlling Instruments and Apparatus
This classification is more appropriate for level control switches that function as part of an automatic regulating or controlling system. These devices often involve more complex mechanisms than simple on/off switches, such as providing continuous feedback, proportional control, or being integral components of larger automated processes. For instance, a level sensor that outputs an analog signal (e.g., 4-20mA) to a Programmable Logic Controller (PLC) for continuous level monitoring and regulation, rather than just a simple on/off signal, would likely fall under this chapter. The HS code 903289 is used for "Other automatic regulating or controlling instruments and apparatus" that don't fit into more specific categories within Chapter 9032.
Choosing the correct HS code depends on a detailed understanding of the level control switch's specific design, function, and how it is intended to be used. Importers and exporters should always verify the classification based on the precise technical specifications of the product.
