Chapter 85 is the chapter in the HS classification system concerning electrical machinery, electrical equipment and parts thereof, covering various electrical devices such as generators, motors, transformers, batteries, switches, lamps, and electronic tubes. The core characteristic of this chapter is that goods must have an electrical function or be used for electrical purposes, but attention must be paid to distinguishing them from mechanical apparatus of Chapter 84 and optical instruments of Chapter 90. Goods in this chapter are widely used in energy, communications, industrial control, and consumer electronics fields, and are a category with relatively high technical content in international trade. Heading 8545 covers carbon electrical articles, including carbon electrodes, carbon brushes, lamp carbons, battery carbons, and various carbon electrical parts. These articles utilize the electrical conductivity, high-temperature resistance, and chemical stability of carbon, and are widely used in electrolysis, electric furnaces, motors, batteries, and other scenarios. This heading includes both finished carbon electrodes and carbon parts specially designed for electrical equipment, but excludes carbon articles for non-electrical uses (such as pencil leads, carbon fiber reinforced materials, etc.). Code 854590 is a 6-digit subheading. The first 2 digits "85" represent Chapter 85 (electrical machinery and equipment); the 3rd-4th digits "45" represent heading 8545 (carbon electrical articles); the 5th-6th digits "90" represent subheading 854590, namely "other carbon electrical parts." This subheading is a residual subheading under 8545, used to classify carbon electrical articles not specified in 8545.11 to 8545.19, such as specially shaped carbon parts, non-standard carbon brushes, carbon seals, etc. When classifying, it is first necessary to determine whether the goods fall under a specific subheading of 8545; if not, they are classified under 854590. The key reason this goods is classified under 854590 rather than adjacent codes is that its material is carbon and it is specially designed for electrical use. If it is a graphite article but for non-electrical use, it should be classified under 6815; if it is a carbon brush but used for non-electrical equipment, it may be classified under part codes such as 8466; if it is a carbon electrode but used for electrolysis, it is classified under 8545.11. Therefore, 854590 applies only to carbon electrical parts not otherwise specified, and must be determined strictly based on material, use, and whether a specific subheading applies.

Product Name: The specific name of the declared goods, which should accurately reflect the material and use, such as "carbon electrical part," "carbon brush," "carbon electrode," etc. Material: State the main composition, such as "carbon," "graphite," "carbon fiber composite," etc., and indicate carbon content or degree of graphitization. Use: Clearly state for what kind of electrical equipment it is used, such as "for electric motors," "for generators," "for electrolytic cells," etc. Brand: Fill in the manufacturer or brand name; if there is no brand, write "no brand." Model: Fill in the product model or specifications, such as "CB-100," "Φ50×200mm," etc. Processing Method: State the forming process, such as "molding," "extrusion," "machining," etc. Whether in Sets: Indicate whether it is imported in sets with other parts, such as "imported separately," "in sets with motors." Product Name: Carbon electrical part (carbon brush); Material: Graphite carbon, carbon content ≥99%; Use: For micro motor commutator; Brand: XX; Model: CB-2024; Processing Method: Molded and then sintered; Whether in Sets: Imported separately. Specifications: 20×10×5mm. Remarks: Not in sets, specially designed for electrical equipment. Mistakenly classifying carbon articles for non-electrical use under 854590, such as pencil leads and carbon fiber boards. Ignoring the specificity of carbon brushes; if used for non-electrical equipment, they should be classified under other part codes. Failing to distinguish carbon electrodes from carbon brushes; carbon electrodes are generally classified under 8545.11, and carbon brushes under 8545.20.

The core criteria for classification are: 1) whether the material is carbon or graphite; 2) whether it is specially designed for electrical equipment; 3) whether it falls under a specified subheading under 8545. If it is a carbon electrode, priority is given to 8545.11; if it is a carbon brush, it is classified under 8545.20; if it is a lamp carbon or battery carbon, it is classified under a specific subheading other than 8545.90. Only carbon electrical parts that do not fall under the above subheadings are classified under 854590. At the same time, attention must be paid to distinguishing them from 6815 (carbon articles for non-electrical use) and 8466 (mechanical parts). 854511 Furnace carbon electrodes: 854511 specifically refers to carbon electrodes used in electric furnaces, while 854590 covers other carbon electrical parts. If a carbon electrode is used for electrolysis or electric furnaces, it should be classified under 854511; if it is a carbon part for other uses, it is classified under 854590. 854520 Carbon brushes: 854520 is specifically for carbon brushes, used for current conduction in motors and other equipment. If the goods are carbon brushes, they must be classified under 854520 and cannot be classified under 854590. 854590 applies only to carbon electrical parts not otherwise specified. 681510 Carbon articles for non-electrical use: 681510 covers carbon or graphite articles for non-electrical uses, such as seals and bearings. If the carbon article is not used for electrical equipment, it should be classified under 681510; if it is specially designed for electrical use, it is classified under 8545. 854590 Other carbon electrical parts: This code is a residual subheading and applies only when the goods are carbon electrical parts and are not specified under other subheadings of 8545. It must be ensured that it does not overlap with other subheadings. Is the material carbon or graphite? Is it specially designed for electrical equipment? Does it fall under a specified subheading of 8545? Is it confused with 6815 or 8466? Are the declaration elements complete and accurate?

Should carbon brushes be classified under 854590 or 854520? Carbon brushes must be classified under 854520, because 854520 is a code specifically established for carbon brushes. 854590 is a residual subheading and applies only to carbon electrical parts not otherwise specified. If carbon brushes are mistakenly classified under 854590, it may lead to classification errors and customs questions. How can one determine whether a carbon article is for electrical use? Electrical use means that the article is used in electrical equipment to achieve electrical functions such as conduction, arc extinction, and high-temperature resistance. For example, carbon brushes used in motor commutators and carbon electrodes used in electrolysis are for electrical use. If it is used only for mechanical sealing or wear resistance, it is not for electrical use and should be classified under 6815. What is the difference in classification between carbon electrodes and carbon brushes? Carbon electrodes generally refer to large-sized carbon electrodes used in electric furnaces or electrolysis, classified under 854511; carbon brushes are sliding contact parts used in motors and other equipment, classified under 854520. The two differ in use and shape and must be strictly distinguished when classifying. What declaration elements are required for importing carbon electrical parts? Product name, material, use, brand, model, processing method, whether in sets, etc. are required. The material must indicate carbon content or degree of graphitization, and the use must clearly state for what kind of electrical equipment it is used. Incomplete declaration elements will affect classification and customs clearance. How can the tax rate for 854590 be checked? Tax rates vary by country, trade agreement, and annual adjustments. It is recommended to check the latest tax rate through the official website of the customs administration, the international trade single window, or by consulting a customs broker. This code does not provide specific tax rate values. How can carbon electrical parts and graphite articles be distinguished in classification? The key is use: if specially designed for electrical equipment, they are classified under 8545; if used in non-electrical fields (such as sealing and lubrication), they are classified under 6815. In addition, there are specific subheadings under 8545 that must be applied first. If carbon parts are imported in sets, how should they be classified? If imported in sets and constituting complete electrical equipment, they should be classified as equipment; if imported separately as parts, they should be classified as parts. If a set contains both carbon parts and parts of other materials, it must be determined based on the main function or value. For cross-border e-commerce sales of carbon electrical parts, how can correct classification be ensured? First confirm the material and use of the goods, and judge step by step against the HS code table. Reference may be made to customs classification decisions or advance classification services. For bulk exports, it is recommended to apply for advance classification to reduce risks.
