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 has an extremely broad scope, covering everything from household appliances to industrial power equipment, from semiconductor devices to communication equipment. The core characteristic is that goods must operate by electrical energy or be dedicated parts of electrical equipment, but articles of pure insulating material (such as insulating articles of plastics, ceramics, or glass) that are not fitted with metal conducting parts are generally classified under the insulating fittings heading of this chapter rather than according to the material. Heading 8547 covers insulating fittings for electrical machines, appliances or equipment, being fittings wholly of insulating material apart from any minor components of metal (for example, threaded sockets, collars, bushes) incorporated during moulding solely for purposes of assembly, other than insulators of heading 8546. It includes insulators, insulating tubing, insulating joints, etc., but excludes insulating fittings specially designed for particular equipment if they are named elsewhere. This heading is divided into subheadings 854710 (of ceramics), 854720 (of plastics) and 854790 (of other materials). Code 854790 is a 6-digit subheading. The first 2 digits '85' represent Chapter 85 (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). Digits 3-4 '47' represent heading 8547 (insulating fittings for electrical machines, appliances or equipment). Digits 5-6 '90' represent subheading 854790, i.e., insulating fittings of 'other' materials, covering insulating fittings made of insulating materials other than ceramics (854710) and plastics (854720), such as glass, mica, rubber, paperboard, synthetic fibers, etc. This subheading is a residual subheading; any insulating fittings not classified under 854710 or 854720 are classified here. The goods are insulating fittings, but the material is neither ceramics nor plastics, so they cannot be classified under 854710 or 854720. At the same time, they must meet the definition of heading 8547: specially designed for electrical machines, appliances or equipment, and consisting essentially of insulating material, with only minor metal components for assembly permitted. If the fitting is a dedicated part of a specific machine and is specifically named in another heading (e.g., electric motor parts under 8503), it should be classified under the specific heading. Therefore, only when the above conditions are met and the material is 'other' should it be classified under 854790.

Product Name: The specific name of the declared commodity, which should accurately reflect its material, use and shape, such as 'glass fiber insulating tube', 'mica insulating gasket'. Material: Detailed description of the specific composition of the insulating material, such as 'glass fiber reinforced plastics', 'mica', 'silicone rubber', 'insulating paperboard', etc. Use: Indicate for which electrical machine, appliance or equipment it is used, such as 'for transformers', 'for electric motors', 'for switchgear'. Brand: The brand or trademark of the declared commodity; if no brand, fill in 'no brand'. Model: The model or specification of the declared commodity, such as 'Φ10×20mm', 'Type A'. Appearance: Describe the shape, color and other appearance features of the commodity, such as 'tubular, black', 'sheet-like, translucent'. Whether Fitted with Metal Parts: State whether it is fitted with metal parts; if so, specify the type and quantity of metal parts, such as 'with two copper terminals'. Product Name: Glass fiber insulating sleeve; Material: glass fiber braided and impregnated with silicone resin; Use: for insulation of electric motor windings; Brand: no brand; Model: Φ5mm; Appearance: tubular, white; Whether fitted with metal parts: no. Mistakenly classifying plastic insulating fittings under 854790 when they should actually be classified under 854720. Failing to specify the use, making it impossible to determine whether it falls under heading 8547. Ignoring the presence of metal parts; if metal parts exceed the scope for assembly purposes, classification under other headings may apply. Mistakenly classifying dedicated parts (such as insulating parts for electric motors) under 854790 when they may actually be classified under 8503. Inaccurate material description, such as misreporting 'glass' as 'plastics'.

Core criteria for classification: First, confirm whether the goods are insulating fittings for electrical machines, appliances or equipment, i.e., specially designed for electrical equipment and consisting essentially of insulating material. Second, check whether the material is ceramics or plastics: if so, classify under 854710 or 854720 respectively; if it is other materials (such as glass, mica, rubber, paperboard, etc.), classify under 854790. At the same time, confirm that the fitting is not specifically named in another heading (e.g., electric motor parts under 8503). Finally, note the permitted range of metal parts: only minor metal parts for assembly purposes (such as screws, rivets) may be present; other metal parts may lead to classification under other headings. 854710 Insulating fittings of ceramics: The material is ceramics, while 854790 is for other materials. Ceramic insulators, bushings, etc. are classified under 854710, while those of glass or mica are classified under 854790. 854720 Insulating fittings of plastics: The material is plastics, while 854790 is for other materials. Plastic insulating tubes, joints, etc. are classified under 854720, while those of rubber are classified under 854790. 854690 Articles of other insulating materials: 854690 covers articles of insulating materials not named elsewhere, not limited to use in electrical equipment; while 854790 specifically refers to insulating fittings for electrical equipment. 8503 Dedicated parts of electric motors and generators: If the insulating fitting is a dedicated part of an electric motor or generator, it should be classified under 8503; only general-purpose insulating fittings are classified under 8547. 392690 Other articles of plastics: If the plastic insulating fitting is not specially designed for electrical equipment, or does not meet the specificity requirements of 8547, it may be classified under 392690. Is it specially designed for electrical machines, appliances or equipment? Is the material ceramics or plastics? If so, classify under 854710 or 854720. Does it contain metal parts? Are the metal parts only for assembly purposes? Is it specifically named in another heading? Is the material description accurate?

How do I check the import tariff rate for 854790? You can check through the official website of the General Administration of Customs of China or the 'Internet + Customs' platform. Enter the 'Import and Export Tariff Query' module, input HS code 854790, select the importing country, country of origin and other information, and the MFN rate, general rate, VAT rate, etc. will be displayed. Note that tariff rates may be adjusted with policy changes; it is recommended to rely on the customs system feedback at the time of declaration. What is the difference between 854790 and 854720? Both are insulating fittings for electrical equipment; the difference lies in the material: 854720 is of plastics, while 854790 is of other materials (such as glass, mica, rubber, etc.). If the material is plastics, it must be classified under 854720; if it is glass fiber reinforced plastics, it is usually classified as plastics, but if glass fiber predominates, it may be classified under 854790. Classification should be determined based on material composition. My product is a rubber insulating sleeve used for cable joints. Which code should it be classified under? If the rubber insulating sleeve is specially designed for cable joints (electrical equipment), is essentially made of rubber, and is not fitted with metal conducting parts, it should be classified under 854790. However, it is necessary to confirm whether it is a dedicated part of a cable joint; if the cable joint itself is classified under 8536, its dedicated parts may be classified under 8538. It is recommended to provide detailed use and material information for accurate classification. What should I pay attention to when declaring goods under 854790? Focus on the completeness of declaration elements: product name, material, use, brand, model, appearance, whether fitted with metal parts. Material and use are key and directly affect classification. If the material is plastics or ceramics, it should be classified under the corresponding subheading. In addition, confirm whether the goods are specially designed for electrical equipment to avoid misclassification under other headings. If the insulating fitting has metal screws, does it affect classification? If the metal screws are only used for assembly and fixation and do not constitute a conducting function, they do not affect classification under 8547. However, if the metal parts exceed the scope for assembly purposes (such as serving as conducting components), they may be regarded as being fitted with metal parts, and reclassification based on essential character may be required, possibly under other headings. The type and function of metal parts should be truthfully stated at the time of declaration. What is the export tax rebate rate for 854790? The export tax rebate rate depends on the specific material and use of the commodity; different materials may be subject to different rebate rates. You can check through the official website of the State Taxation Administration or the export tax rebate query system by entering HS code 854790. Note that rebate rates may be adjusted; it is recommended to rely on the tax system at the time of declaration. How do I determine whether an insulating fitting is specially designed for electrical equipment? Specially designed for electrical equipment means that the fitting is designed to be used only for electrical machines, appliances or equipment and cannot be used in other situations. For example, insulating bushings for transformers, insulating slot wedges for electric motors, etc. If the fitting is general-purpose and can be used for non-electrical equipment, it may be classified under other headings (such as 854690). When making a determination, reference can be made to product manuals, industry standards and customs classification decisions. Are 854790 and 854690 easily confused? Yes, they are easily confused. 854690 covers 'articles of insulating materials not named elsewhere', not limited to use in electrical equipment; while 854790 specifically refers to insulating fittings for electrical equipment. If the insulating article is clearly used for electrical equipment, it should be classified under 8547 first; if the specificity cannot be determined, or it is used in non-electrical fields, it should be classified under 854690. Use should be a key focus during classification review.
