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 is a concentration of technology-intensive products in the HS classification, involving a wide range from household appliances to industrial electrical equipment. Insulators, as key insulating components of electrical equipment, are used to support and isolate conductors and prevent current leakage, and are therefore classified in this chapter. Heading 8546 specifically covers insulators of any material, including glass, ceramics, plastics, rubber, etc. The core function of insulators is electrical insulation and mechanical support, and they are widely used in power transmission, distribution, and electrical equipment. This heading is further subdivided by material and use, such as glass insulators, ceramic insulators, etc., while 854690 is a residual subheading covering other insulators not elsewhere specified or included. Code 854690 is a 6-digit HS code: the first 2 digits "85" represent Chapter 85 (electrical machinery and equipment and parts thereof); digits 3-4 "46" represent heading 8546 (insulators); digits 5-6 "90" represent subheading 854690, i.e., "other insulators." This subheading is a residual subheading under 8546, used to classify insulators not specifically named in 854610 to 854680, such as those made of plastics, rubber, composite materials, etc. This commodity is classified under 854690 because it is an insulator and its material is not specifically named in other subheadings under 8546 (such as glass 854610, ceramics 854620, etc.). If it were a glass or ceramic insulator, it should be classified under the corresponding subheading; if it is made of other materials (such as plastics, rubber, composite materials), it is classified under 854690. At the same time, attention must be paid to the difference from 8544 (insulated wire and cable), which are conductors with an insulating layer, rather than separate insulators.

Product name: The specific name of the declared commodity, which should accurately reflect its material and use, such as "plastic insulator," "composite insulator." Material: Detailed description of the main material of the insulator, such as plastics, rubber, composite materials (e.g., epoxy resin fiberglass), etc. Use: Explain the application scenario of the insulator, such as for power lines, transformers, switchgear, electrical equipment, etc. Brand: If there is a brand, declare the brand name; if there is no brand, declare "no brand." Model: Declare the model or specifications of the product, such as dimensions, voltage level, etc. Voltage level: The rated voltage of the insulator, such as 10kV, 35kV, etc., used to determine its applicable scenario. Whether in complete sets: Declare whether it is in complete sets of unassembled articles or a finished product, which affects classification. Customs declaration example: Product name: Plastic insulator Material: Polypropylene (PP) Use: Used for 10kV power lines, supporting conductors and providing insulation Brand: No brand Model: PP-10kV Voltage level: 10kV Whether in complete sets: No Remarks: This insulator is injection-molded, not made of glass or ceramics, and meets the classification under 854690. False declaration of material: Misreporting a plastic insulator as ceramic, leading to classification under 854620 instead of 854690. Use description too broad: For example, only writing "for electrical use" without specifying the specific equipment or scenario, affecting classification. Ignoring voltage level: Failure to declare the voltage level may make it impossible to determine whether it is a high-voltage insulator, affecting regulatory conditions.

The core basis for classification is the material and use of the insulator. First, according to HS rules, insulators are classified by material: glass articles are classified under 854610, ceramic articles under 854620, and other materials (such as plastics, rubber, composite materials) under 854690. Second, it must be confirmed whether the commodity is an insulator, i.e., a separate component used for electrical insulation and mechanical support, rather than insulated wire and cable (8544) or parts of electrical equipment (such as 8547). Finally, if the insulator is in complete sets of unassembled articles, it should be classified as a finished product. 854610 Glass insulators: The material is glass, whereas 854690 is for other materials (such as plastics, rubber). The core difference is the material; glass insulators are usually used for high-voltage lines but are classified under 854610. 854620 Ceramic insulators: The material is ceramic, whereas 854690 is for other materials. Ceramic insulators are commonly found in power equipment but are classified under 854620. 854690 Other insulators: This code is a residual subheading covering insulators of other materials not elsewhere specified. If the material is plastics, rubber, composite materials, etc., classify under this code. 8544 Insulated wire and cable: 8544 covers conductors with an insulating layer, used to transmit current; whereas 854690 covers separate insulators, used to support and isolate conductors, not to transmit current. 8547 Insulating fittings for electrical equipment: 8547 covers insulating fittings for electrical equipment, such as insulating tubes, insulating joints, etc., usually as equipment parts; whereas 854690 covers separate insulators with a supporting function. Confirm whether the commodity is an insulator, rather than insulated wire or equipment parts. Confirm whether the material is glass or ceramic; if so, classify under 854610 or 854620. Confirm whether the material is other (such as plastics, rubber, composite materials); if so, classify under 854690. Confirm whether the use is electrical insulation and mechanical support. Confirm whether it is in complete sets of unassembled articles; if so, classify as a finished product.

How can I check the tax rate for HS code 854690? You can enter 854690 on the official website of the General Administration of Customs of China, the International Trade Single Window, or a professional HS code query platform to view the latest import tariff, value-added tax, and regulatory conditions. Note that tax rates are subject to policy adjustments; it is recommended to rely on the latest official announcements. What is the difference in classification between plastic insulators and ceramic insulators? Plastic insulators are classified under 854690, and ceramic insulators under 854620. The core difference is the material. Ceramic insulators are usually high-temperature and high-voltage resistant, while plastic insulators are low-cost and lightweight. The material must be accurately declared during classification. How are insulators distinguished from insulated wire and cable? Insulators are separate components used to support and isolate conductors and do not transmit current; insulated wire and cable are conductors with an insulating layer used to transmit current and are classified under 8544. If the commodity is a cable with insulators, it is usually classified as cable. What regulatory documents are required when declaring 854690? Usually no special regulatory documents are required, but if used for high-voltage power equipment, it may involve compulsory product certification (CCC) or export quality license. The specifics depend on the use and voltage level. It is recommended to consult a customs broker or customs. Under which code are composite insulators classified? Composite insulators are usually made of composite materials such as epoxy resin and fiberglass, which are not glass or ceramic, and are therefore classified under 854690. When declaring, the material must be indicated as composite material. What is the export tax rebate rate for 854690? The export tax rebate rate is subject to national policy adjustments. Currently, the export tax rebate rate for 854690 needs to be checked in the latest export tax rebate database. You can check through the electronic tax bureau or customs official website, or consult a professional tax advisor. If the insulator is in complete sets of unassembled articles, how should it be classified? According to the General Rules for the Interpretation of the HS, complete sets of unassembled articles that already have the essential character of a finished product should be classified as a finished product. Therefore, complete sets of unassembled insulators should be classified under 854690, not as parts. How are 854690 and 8547 insulating fittings distinguished? 854690 covers separate insulators, mainly used to support and isolate conductors; 8547 covers insulating fittings for electrical equipment, such as insulating tubes, insulating joints, usually as special parts for equipment. The key to distinction is function: insulators provide support, while fittings provide insulation protection.
