Chapter 85 is the core chapter of electrical and electronic equipment in the HS classification system, covering electric motors, generators, transformers, batteries, switches, relays, lamps, cables, insulators, etc. Goods in this chapter generally involve the production, transmission, conversion or control of electrical energy, as well as equipment that operates using electrical energy. Within the chapter, tariff headings are divided by function, from power generation (8501) to lighting (8539), electronic components (8540-8542), etc., making it one of the chapters with the densest classification of electromechanical products. Heading 8536 covers electrical circuit switches, protection or connection devices for circuits with a voltage not exceeding 1000 volts. Specifically, it includes switches, relays, fuses, surge suppressors, plugs and sockets, lamp holders, junction boxes, etc. Its core function is to safely make, break or connect circuits, and it belongs to basic low-voltage electrical components. 8536 forms a voltage boundary with 8535 (high-voltage circuit devices), and is distinguished from 8544 (insulated wires and cables) by whether connecting devices are included. Code 853669 is a six-digit subheading. The first 2 digits 85 represent Chapter 85 (electrical and electronic equipment). Digits 3-4, 36, represent heading 8536 (electrical circuit switches, protection or connection devices for voltage ≤1000V). Digits 5-6, 69, represent subheading 8536.69, namely "other plugs, sockets and connectors." Under 8536, 8536.10 is fuses, 8536.20 is automatic circuit breakers, 8536.30 is other circuit protection devices, 8536.41 to 8536.49 are relays, 8536.50 is other switches, 8536.61 is lamp holders, 8536.69 is other plugs, sockets and connectors, and 8536.90 is other devices. Therefore, 853669 specifically refers to plugs, sockets and connectors not otherwise named, such as USB interfaces, audio jacks, terminal blocks, etc. The goods are plugs, sockets or connectors used for low-voltage circuit connection, conforming to the description of heading 8536. 8536.69 is the residual subheading for plugs and sockets, because 8536.61 is limited to lamp holders, 8536.50 is switches, and 8536.90 is other connection devices but usually refers to junction boxes, etc. If for high voltage (>1000V), classification would be 8535; if for optical fiber connectors, classification would be 8536.70; if for wires and cables with connectors, classification may be 8544. Therefore, ordinary low-voltage plugs, sockets and connectors should be classified under 853669.

Product name: The specific name of the declared goods, such as "plug," "socket," "connector," etc., which should accurately reflect the product's attributes and avoid broadly writing "electronic accessory." Use: Explain the product's usage scenario, such as "for power connection of household appliances," "for computer data transmission," etc., which helps determine classification. Brand: Fill in the product brand; if there is no brand, write "unbranded" or "neutral." Brand affects customs intellectual property protection and price review. Model: Fill in the model assigned by the manufacturer, used to distinguish products of the same brand with different specifications, facilitating customs inspection and classification. Voltage: Indicate the rated voltage (unit: volts), which must be ≤1000V; otherwise it should be classified under 8535. This is a key classification element. Rated current: Fill in the rated current (unit: amperes), which assists in determining the product specifications and whether it falls within the scope of 8536. Material: The material of the main conductor (such as copper, brass) and the material of the insulator (such as plastic, ceramic), which affects classification and customs valuation. Whether it includes wire: Indicate whether it has a wire or cable. If it includes wire and the length exceeds a certain value, it may be classified under 8544. Product name: USB Type-C connector; Use: for data transmission and charging of smartphones; Brand: TE Connectivity; Model: 1-1734346-1; Voltage: 5V; Rated current: 3A; Material: plastic housing, copper alloy terminals; Whether it includes wire: no wire. Note: This product is a low-voltage connector and conforms to subheading 853669. Failure to distinguish voltage levels: plugs and sockets exceeding 1000V should be classified under 8535, not 8536. Misclassification of plugs with wire: if the plug and wire are assembled as one unit and the wire length exceeds 2 meters, it is usually classified under 8544. Misclassification of lamp holders: lamp holders should be classified under 8536.61, not 8536.69, and must be determined according to function. Misclassification of optical fiber connectors: optical fiber connectors are classified under 8536.70, and 853669 does not apply. Confusion between switches and connectors: switches are classified under 8536.50, connectors under 8536.69, and their functions differ.

Core basis for classification: 1) whether the voltage is ≤1000V; if it exceeds this, classify under 8535; 2) whether the function is circuit connection rather than switching, protection or lighting; 3) whether it is specially designed for lamp holders (8536.61) or optical fibers (8536.70); 4) whether it includes wires or cables (8544); 5) whether it belongs to other devices under 8536.90 (such as junction boxes). 853669 is the residual subheading for plugs, sockets and connectors, applicable to low-voltage connecting devices not otherwise named. 8535 High-voltage electrical circuit switches, protection or connection devices: 8535 applies to circuit devices with voltage exceeding 1000V, while 8536 applies to ≤1000V. If plugs and sockets are used for high voltage, they should be classified under 8535. 8536.50 Other switches: 8536.50 is switches, used to make/break circuits; 8536.69 is connectors, used for fixed circuit connection and does not have a switching function. 8536.61 Lamp holders: 8536.61 specifically refers to lamp holders, used for installing bulbs; 8536.69 is general plugs, sockets and connectors, not limited to lamp holders. 8536.70 Optical fiber connectors: 8536.70 is specifically for optical fiber connectors, while 8536.69 applies to electrical connectors; the transmission media differ. 8544 Insulated wires, cables and other insulated electrical conductors: 8544 includes wires and cables with connectors. If the plug and wire are assembled as one unit and the wire length exceeds a certain value, classification should be under 8544. Is the voltage clearly ≤1000V? Is the function circuit connection rather than switching or protection? Is it specially designed for lamp holders or optical fibers? Does it include wires or cables? Does it belong to other devices under 8536.90?

What is the difference between plugs and sockets under HS code 853669 and switches under 8536.50? 8536.50 is switches, used to control the making and breaking of circuits, such as push-button switches and toggle switches; 853669 is plugs, sockets and connectors, used for fixed circuit connection, such as power plugs and USB interfaces. Switches have an operating mechanism, while connectors only provide electrical connection. Should a plug with wire be classified under 853669 or 8544? If the plug and wire are assembled as one unit and the wire length exceeds 2 meters or it is clearly used as a wire or cable, it is usually classified under 8544; if it is only a short wire segment (such as the output wire of a power adapter) and its main function is connection, it may be classified under 853669. The specific customs classification decision shall prevail. How can one determine whether a plug or socket exceeds 1000V? Check the rated voltage on the product nameplate or instruction manual. If the nominal voltage is ≤1000V, classify under 8536; if >1000V, classify under 8535. Common household and industrial plugs and sockets are mostly 250V or 400V, belonging to 8536. Why can't optical fiber connectors be classified under 853669? Because the HS code establishes a separate subheading 8536.70 specifically for optical fiber connectors. 853669 applies to electrical connectors, and the transmission media differ, so they must be distinguished during classification. Is 3C certification required when declaring 853669? 3C certification is China's compulsory product certification and has no direct correspondence with HS codes. Some plugs and sockets are products within the 3C catalog and require a 3C certificate upon import. It is recommended to consult the latest Catalog of Compulsory Product Certification or consult a customs broker. What is the export tax rebate rate for 853669? The export tax rebate rate changes with national policies and may differ across periods. It is recommended to check the latest rebate rate through the official websites of the State Taxation Administration or the General Administration of Customs, or use professional customs declaration software. This answer does not provide a specific figure. If plugs and sockets are used in automobiles, are they still classified under 853669? If automotive plugs and sockets are low-voltage (≤1000V) and do not constitute vehicle-specific parts, they are usually still classified under 853669. However, if they are automotive-specific connectors and meet the characteristics of vehicle parts, they may be classified under Chapter 87. Judgment should be based on the specific use and design. How are 853669 and 8536.90 distinguished? 8536.69 is plugs, sockets and connectors, while 8536.90 is other circuit connection devices, such as junction boxes, terminal blocks, cable joints, etc. If the main function of the product is to connect two wires or provide a wiring point, it may be classified under 8536.90; if it is in the form of a plug or socket, classify under 8536.69.
