Chapter 85 covers electric motors, electrical equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories thereof. This chapter is one of the most technology-intensive chapters in the HS classification, involving various types of equipment for the production, transformation, storage, transmission, distribution, and use of electrical energy. From simple switches and sockets to complex integrated circuits and communication equipment, all are classified under this chapter. Within the chapter, headings are divided by function, such as 8501 electric motors, 8504 transformers, 8535 high-voltage switches, 8536 low-voltage connecting devices, etc. The core distinctions lie in voltage level, functional use, and whether they constitute complete machines. 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 volts, including switches, relays, fuses, plugs and sockets, lamp-holders, junction boxes, etc. However, the subheadings under 8536 are divided by specific type, such as 853610 fuses, 853620 automatic circuit breakers, 853630 other apparatus for protecting electrical circuits, 853641/49 relays, 853650 other switches, 853661/69 lamp-holders, 853670 optical fiber connectors, 853690 other apparatus for making connections to or in electrical circuits. The core of this heading is low-voltage (≤1000V) electrical connection and protection devices, distinguished from the high-voltage (>1000V) similar apparatus of 8535. The first 2 digits 85 indicate Chapter 85 (electric motors, electrical equipment and parts thereof). Digits 3-4, 36, constitute heading 8536, referring to electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits, for a voltage not exceeding 1000 volts. Digits 5-6, 90, form the subheading, indicating "other apparatus for making connections to or in electrical circuits," i.e., connection devices not named under other subheadings of 8536 (such as fuses, circuit breakers, relays, switches, lamp-holders, optical fiber connectors, etc.). This subheading is a residual subheading, covering such items as terminal blocks, connectors, plug-in connectors, cable joints, busbar connections, etc., but must satisfy the conditions of voltage ≤1000V and not belonging to other more specific subheadings. This commodity is classified under 853690 rather than adjacent codes because its function is electrical connection, its voltage does not exceed 1000V, and it is not covered by more specific subheadings under 8536 (such as 853650 switches, 853669 plugs and sockets). For example, if it were a plug or socket, it should be classified under 853669; if it were a switch, it should be classified under 853650. As a residual subheading, 853690 applies to terminal blocks, connectors, cable joints, etc., but attention must be paid to distinguishing it from 8544 insulated wire and cable, 8538 dedicated parts, etc.

Product Name: The Chinese and English names of the declared commodity, which should accurately reflect the product's attributes, such as "terminal block," "connector," "cable joint," etc. Use: Explain the final use scenario of the commodity, such as for household appliances, industrial control cabinets, automotive circuits, communication equipment, etc. Material: Main constituent materials, such as copper alloy, plastic, brass, phosphor bronze, etc. Metal parts and insulation parts need to be described separately. Voltage: Rated voltage value; it must be clearly stated whether it does not exceed 1000V, which is the key condition for classification under 8536. Brand: Manufacturer or brand name; if there is no brand, indicate "no brand." Model: Product model or specification code, used to uniquely identify the commodity. Structure Type: Such as plug-in type, threaded type, crimp type, welded type, etc., describing the connection method. Product Name: Terminal Block; Use: For wire connection in industrial control cabinets; Material: Copper alloy conductor, PA66 insulating housing; Voltage: 250V; Brand: XX; Model: UK-2.5B; Structure Type: Screw crimp type. Mistakenly classifying connection devices with voltage exceeding 1000V under 853690; they should be classified under 8535. Mistakenly classifying plugs and sockets under 853690; they should actually be classified under 853669. Mistakenly classifying switches under 853690; they should actually be classified under 853650. Failing to distinguish dedicated parts from general connection devices; 8538 parts are not classified under 853690.

Core criteria for classification: 1) Whether the voltage does not exceed 1000V; 2) Whether the function is electrical circuit connection; 3) Whether it belongs to other more specific subheadings under 8536; 4) Whether it constitutes a complete machine or a dedicated part. If the voltage exceeds 1000V, classify under 8535; if it is a plug or socket, classify under 853669; if it is a switch, classify under 853650; if it is a fuse, classify under 853610. 853690 applies only to other connection devices not elsewhere specified, such as terminal blocks, connectors, cable joints, etc. 853669 Plugs and sockets: 853669 specifically refers to plugs and sockets for pluggable connections; 853690 is for fixed connections, such as terminal blocks and connectors, which are not pluggable. 853650 Other switches: 853650 refers to switches used to control the on/off of circuits; 853690 refers to connection devices used only for conductive connection, with no switching function. 853890 Dedicated parts for 8535/8536/8537: 853890 refers to dedicated parts, such as housings and contacts; 853690 refers to complete connection devices with independent functions. 854442 Other insulated wire and cable for a voltage ≤1000V: 854442 refers to wire and cable fitted with connectors; if the connector is declared separately, classify under 853690; if it comes with cable, classify under 854442. Is the voltage ≤1000V? Does it have a switching or protection function? Is it a pluggable plug or socket? Is it already named under another subheading of 8536? Does it constitute a complete connection device rather than a part?

How can I check the import tariff rate for 853690? You can check the MFN rate, agreement rate, etc., through the official website of the General Administration of Customs, China International Trade Single Window, or third-party tariff inquiry platforms by entering HS code 853690 and the country of origin. Note that tariff rates are subject to policy adjustments; it is recommended to rely on the latest official data. How to distinguish 853690 from 853669? 853669 specifically refers to plugs and sockets for pluggable connections; 853690 refers to other connection devices, such as terminal blocks, connectors, cable joints, etc., for fixed connections. If the product has pins and receptacles, it is usually classified under 853669. What are the consequences of incorrectly filling in voltage during declaration? Voltage is the key to distinguishing 8536 from 8535. If a product exceeding 1000V is declared as 853690, it may be deemed inaccurate declaration, leading to tax recovery, fines, or even affecting the enterprise's credit rating. The rated voltage must be declared truthfully. What is the export tax rebate rate for 853690? The export tax rebate rate should be checked according to the latest policy, usually available on the website of the State Taxation Administration or the General Administration of Customs. The rebate rate may be adjusted in different periods; it is recommended to rely on the latest policy at the time of export. Should terminal blocks be classified under 853690? Yes, terminal blocks are used for fixed connection of conductors, usually at a voltage not exceeding 1000V, and do not belong to other subheadings, so they should be classified under 853690. However, note that if they have a switching function, they may be classified under 853650. Are optical fiber connectors classified under 853690? Optical fiber connectors should be classified under 853670, not 853690. 853670 specifically refers to optical fiber connectors, optical fiber adapters, etc., used for optical fiber connection. 853690 applies to electrical connections, not optical fibers. Must all declaration elements for 853690 be filled in? Yes, declaration elements are an important basis for customs review and classification and must be filled in completely and accurately. Missing or incorrect information may lead to rejection, inspection, or classification disputes. It is recommended to fill them in according to the customs standard declaration catalog. How to determine whether a connector belongs to 853690? First confirm that the voltage is ≤1000V, then confirm that the function is electrical connection, and that it does not belong to other subheadings of 8536 (such as switches, plugs and sockets, fuses, etc.). If it is a dedicated part, it should be classified under 853890; if it is a connector with cable, it should be classified under 854442.
