Chapter 85 is the major category of electromechanical products in the HS classification system, covering electric motors, generators, transformers, batteries, wires and cables, switches, lamps, electronic components, communication equipment, sound recording and reproducing equipment, integrated circuits, etc. Goods in this chapter generally have electrical or electronic functions and are a category with relatively high technical content and relatively complex regulatory conditions in international trade. 8544 belongs to the heading in this chapter for insulated wires and cables and optical fiber cables, and is closely related to electronic equipment, communications, and power transmission. Heading 8544 covers insulated wires, cables and other insulated electric conductors (including coaxial cables) as well as optical fiber cables. However, optical fiber cables made of independently sheathed optical fibers are classified under 9001; cables fitted with connectors remain classified under 8544. Products under this heading are mainly used to transmit power, signals, or data, and are widely used in communications, electronics, automobiles, industrial control, and other fields. 854420 is the subheading for coaxial cables therein. First 2 digits 85: Chapter 85, representing the major category of electromechanical products. Digits 3-4: 44: heading 8544, representing insulated wires, cables and other insulated electric conductors; optical fiber cables. Digits 5-6: 20: subheading 854420, representing coaxial cables. Coaxial cables consist of an inner conductor, insulation layer, outer conductor (shielding layer), and sheath, and are used to transmit high-frequency signals. Note that 854420 only includes coaxial cables and does not include other types of cables (such as 854411, 854419, 854430, etc.). Coaxial cables have a unique coaxial structure and are used for high-frequency signal transmission, so they are classified under 854420. If they are ordinary power cables or signal cables, they are classified under 854411 (enameled wire), 854419 (other winding wire), 854430 (ignition wiring sets), 854442 (other electric conductors fitted with connectors), etc. If they are optical fiber cables, they are classified under 854470. Coaxial cables without connectors are classified under 854420; if fitted with connectors, they are still classified under 854420 because the coaxial cable itself already constitutes a complete article.

Product name: 同轴电缆 Coaxial cable; Structure type: coaxial structure, inner conductor is single-strand copper wire, insulation layer is foamed polyethylene, outer conductor is braided copper mesh, sheath is polyvinyl chloride; Material: inner conductor copper, insulation layer PE, shielding layer copper, sheath PVC; Rated voltage: 300V; Specifications and dimensions: inner conductor diameter 0.5mm, outer diameter 6.0mm, 100 meters per roll; Whether fitted with connectors: No; Use: used for cable television signal transmission; Brand and model: no brand, model RG6. Mistakenly classifying coaxial cable under 854442 (other electric conductors fitted with connectors), ignoring the coaxial structure. Failing to declare the rated voltage, making it impossible to determine whether it falls within the scope of 8544. Mistakenly declaring optical fiber cable as coaxial cable; optical fiber cable should be classified under 854470.

Core basis for classification: first confirm whether the product is an insulated electric conductor and whether it has a coaxial structure. Coaxial cable consists of an inner conductor, insulation layer, outer conductor, and sheath, and the outer conductor is usually a metal braid or foil layer used for shielding. If it conforms to this structure, it is classified under 854420. If it is an ordinary cable, it is classified under 854411, 854419, 854430, 854442, etc. according to whether it is fitted with connectors, its use, and other factors. If it is an optical fiber cable, it is classified under 854470. In addition, attention should be paid to the voltage level, but 8544 is not divided by voltage, but by structure type. 854411 Enameled wire: Enameled wire is winding wire made of copper or aluminum conductor coated with insulating varnish, used for motor and transformer windings, and has no coaxial structure. 854419 Other winding wire: Other winding wire includes wrapped wire, inorganic insulated wire, etc., used for windings, and is not a coaxial structure. 854430 Ignition wiring sets and other wiring sets: Wiring sets used for vehicles, aircraft, etc., composed of multiple insulated wires and fitted with connectors, and are not coaxial cables. 854442 Other electric conductors fitted with connectors: Ordinary cables fitted with connectors, with a rated voltage of ≤1000V, and not a coaxial structure. 854470 Optical fiber cables: Optical fiber cables are composed of optical fibers and transmit optical signals rather than electrical signals, and their structure is completely different. Does the product have a coaxial structure? Is it fitted with connectors? Is the rated voltage below 1000V? Is it used for high-frequency signal transmission? Could it be confused with 854442?

What is the difference in HS codes between coaxial cables and ordinary cables? Coaxial cables are classified under 854420, while ordinary cables are classified under 854411, 854419, 854430, 854442, etc. according to type. The key difference is that coaxial cables have a coaxial structure and are used for high-frequency signal transmission, while ordinary cables are used for power or low-frequency signals. Under which code should a coaxial cable fitted with connectors be classified? It is still classified under 854420. Because the coaxial cable itself already constitutes a complete article, even if fitted with connectors, its basic characteristics as a coaxial cable do not change. However, it is necessary to indicate in the declaration elements that it is fitted with connectors. How can I check the import tariff rate for coaxial cables? Tariff rates may change. It is recommended to check through the official website of the General Administration of Customs, China International Trade Single Window, or professional databases. It is necessary to enter HS code 854420 and the country of origin to obtain the MFN rate, general rate, VAT, etc. Among the declaration elements for coaxial cables, which are most prone to error? Common errors include: failing to indicate the coaxial structure, omitting the rated voltage, non-specific material descriptions, and failing to declare whether connectors are fitted. It is recommended to declare strictly in accordance with the specifications to avoid classification disputes. Can optical fiber cables and coaxial cables be classified under the same code? No. Optical fiber cables are classified under 854470, and coaxial cables under 854420. The transmission media are different: optical fiber cables transmit optical signals, while coaxial cables transmit electrical signals, and the structural differences are significant. If a coaxial cable is used in an automobile, is it classified under 854430? It is not classified under 854430. 854430 is for ignition wiring sets and other wiring sets, usually composed of multiple wires, used in automobiles, aircraft, etc. If a coaxial cable is used for automotive radio frequency signals, it is still classified under 854420. Is the classification of coaxial cables affected by voltage? Heading 8544 is not divided by voltage, and subheading 854420 for coaxial cables also does not specify a voltage limit. However, if the voltage exceeds 1000V, could it be classified under other subheadings of 8544? In fact, 8544 includes insulated electric conductors of all voltages, but note that 854420 applies only to coaxial cables. What should be noted when declaring coaxial cables for cross-border e-commerce sales? It is necessary to accurately declare the product name, structure, material, use, etc., to avoid mistakenly declaring coaxial cables as ordinary cables. Also note whether 3C certification is required and whether they comply with the standards of the destination country. It is recommended to keep product specification sheets for customs inspection.
