Chapter 85 covers electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles. This chapter is the most concentrated chapter in the HS classification for electromechanical products, involving power generation, transformation, electrical energy control, communications, audio and video, and many other fields. Goods in this chapter generally operate on electrical or electronic principles, but certain equipment for specific uses is excluded (such as machinery of Chapter 84). Headings within the chapter are arranged by function or use, and 8536 covers electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits. Heading 8536 covers electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits, for a voltage not exceeding 1000 V. Specifically, it includes: switches, relays, fuses, surge suppressors, plugs and sockets, lamp-holders, junction boxes, etc. Note, however, that 8536 applies only to apparatus with a voltage ≤1000 V; switching apparatus exceeding 1000 V is classified under 8535. Goods under this heading are mostly basic components for electrical control and are widely used in industry, home appliances, automobiles, and other fields. First 2 digits 85: indicates Chapter 85 (electrical machinery and equipment and parts thereof). Digits 3-4, 36: indicates heading 8536 (electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits, voltage ≤1000 V). Digits 5-6, 50: indicates subheading 853650, namely "other switches," but according to the HS code structure, 853650 specifically is "electromechanical switches (including relays)"? In fact, HS code 853650 is "other switches," while electromechanical switches may be classified under 853650 or other subheadings. However, according to what the user provided, 853650 is electromechanical switches (including relays). Digit-by-digit breakdown: Chapter 85 (electrical equipment); heading 36 (switching, protecting, connecting apparatus); subheading 50 (electromechanical switches, including relays). Note: subheading 853650 in the HS generally refers to "other switches," but the specific scope must be determined by reference to the latest HS notes. This product is an electromechanical switch (including relays), and its operating principle is based on mechanical action to make or break or change electrical circuits, with a voltage not exceeding 1000 V. Therefore, it is classified under 8536, not 8535 (switching apparatus with voltage >1000 V). At the same time, it is different from 8541 (semiconductor devices) or 8542 (integrated circuits), because its core is mechanical contact action, not semiconductor effects. It is also not classified under 8537 (control panels), because 8537 is a combination board of multiple devices.

Product name: The specific name of the declared commodity, such as "electromechanical switch" or "relay," and it must be consistent with the actual goods. Brand: Fill in the manufacturer or brand name; if there is no brand, fill in "no brand." Model: Fill in the product model or specification for unique identification. Voltage: Indicate the rated voltage in volts (V), and it must be clear whether it is ≤1000 V. Use: Explain the application scenario of the switch or relay, such as "used for household appliance control." Operating principle: Briefly describe the mechanical action method, such as "by contact closing/opening." Rated current: Fill in the maximum current allowed to pass through the switch or relay, in amperes (A). Product name: electromechanical switch (relay); Brand: OMRON; Model: G5V-1; Voltage: 24V; Use: for making and breaking circuits in industrial control equipment; Operating principle: electromagnetic coil drives mechanical contact action; Rated current: 1A. Failure to distinguish whether the voltage exceeds 1000 V, resulting in incorrect classification under 8535. Mistakenly declaring an electronic switch (such as a MOSFET) as an electromechanical switch. The use description is too general, leading to classification disputes.

Core criteria for classification: 1) whether the voltage is ≤1000 V; 2) whether mechanical action is used to make or break circuits; 3) whether it belongs to switching, protecting, or connecting apparatus. If the voltage is >1000 V, classify under 8535; if it is a semiconductor switch, classify under 8541 or 8542; if it is a switch combination board, classify under 8537. The key feature of an electromechanical switch is that it relies on mechanical force (such as a spring or electromagnetism) to close or open contacts. 8535 Electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits (voltage >1000 V): 8535 applies to apparatus with voltage exceeding 1000 V, while 8536 applies to ≤1000 V. Voltage is the core distinguishing point. 8541 Semiconductor devices: 8541 includes semiconductor switches such as diodes and transistors, whose operating principle is based on semiconductor effects rather than mechanical action. 8537 Control panels, boards, etc.: 8537 is a combination board of multiple devices, while 8536 is a single switch or relay. If a switch is assembled with other devices into a board, it is classified under 8537. 8536 Other subheadings such as 853610 (fuses): 853610 is fuses, used for overcurrent protection, while 853650 is switches, used for making and breaking circuits. Their functions are different. Is the voltage clearly ≤1000 V? Is the circuit made or broken by mechanical action? Is it a single switch or relay? Is it used for circuit control rather than protection? Is it distinguished from the combination board of 8537?

What is the difference in HS classification between electromechanical switches and electronic switches? Electromechanical switches rely on mechanical contact action and are classified under 8536; electronic switches (such as transistors and solid-state relays) are based on semiconductor principles and are classified under 8541 or 8542. The core difference lies in the operating principle. Under which HS code should relays be classified? If the relay is electromechanical and the voltage is ≤1000 V, it is classified under 8536 (the specific subheading may be 853641 or 853649, depending on voltage and current). If it is a solid-state relay, it is classified under 8541. How can it be determined whether a switch's voltage exceeds 1000 V? Check the rated voltage in the product specification sheet. If the rated voltage is ≤1000 V, classify under 8536; if >1000 V, classify under 8535. Note that the peak value of AC voltage may affect the determination. What goods are specifically included in subheading 853650? 853650 generally refers to "other switches," including push-button switches, toggle switches, micro switches, and other electromechanical switches. However, the specific scope must be determined by reference to the latest HS notes, and different versions may have adjustments. What additional information is required for relays at the time of declaration? In addition to the basic elements, coil voltage, contact form (normally open/normally closed), rated current, etc., must be provided for accurate classification. If a switch and socket are combined together, how should it be classified? If the main function of the combined device is switching, it may still be classified under 8536; if the socket is the main function, classify under the socket subheading of 8536. If it is a combination board, classify under 8537. For cross-border e-commerce sales of switches, how can the HS code be queried? It can be queried through the official website of the General Administration of Customs, HS code query tools, by entering keywords such as "switch" or "relay," and filtering by voltage and operating principle. It is recommended to consult a professional customs broker. How can the tariff rate for switches under 8536 be queried? Tariff rates vary by country and trade agreement. You can query the customs tariff of the destination country, or check through China Customs' "Import and Export Tariff." Note that tariff rates may change, and the latest version shall prevail.
