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 one of the most technology-intensive chapters in the HS classification, covering various types of equipment for the generation, conversion, storage, transmission, and utilization of electrical energy, ranging from household appliances to large-scale industrial electrical installations, but excluding certain electrical equipment for specific purposes (such as mechanical apparatus of Chapter 84). Heading 8514 covers industrial or laboratory electric furnaces and ovens (including those functioning by induction or dielectric loss); other industrial or laboratory equipment for the heat treatment of materials by induction or dielectric loss. This heading primarily targets equipment that uses electrical energy for heating, melting, heat treatment, and other industrial processing, including resistance furnaces, arc furnaces, induction furnaces, microwave furnaces, etc., but excluding rapid thermal processing equipment used for semiconductor manufacturing. The first 2 digits 85 indicate Chapter 85 (electrical machinery and equipment and parts thereof). The 3rd-4th digits 14 indicate heading 8514, i.e., industrial or laboratory electric furnaces and ovens. The 5th-6th digits 30 indicate subheading 851430, specifically electric arc furnaces. An electric arc furnace is equipment that uses the heat of an electric arc generated between electrodes and the charge to melt metals or heat materials, mainly used for steel smelting, ferroalloy production, and non-ferrous metal melting. This subheading can be further subdivided, but the six-digit code is already specific to electric arc furnaces, distinguishing them from resistance furnaces (851410), induction furnaces (851420), and other electric furnaces. The core characteristic of an electric arc furnace is the use of an electric arc as the heat source, rather than resistance heating or induction heating. Its structure includes electrodes, a furnace body, a tilting mechanism, etc., and it operates at extremely high temperatures for melting purposes. The adjacent 851410 is resistance furnaces, which generate heat through resistance; 851420 is induction furnaces, which generate heat through electromagnetic induction. The heating principle and application of electric arc furnaces are fundamentally different from these, hence classified under 851430.

Remarks: This equipment is an AC electric arc furnace, electrode diameter 600mm, furnace shell inner diameter 5.2m. Misclassifying electric arc furnaces under 851410 (resistance furnaces) or 851420 (induction furnaces), leading to differences in tax rates and regulatory conditions. Failure to indicate "arc heating" in the declaration, writing only "electric heating," which may be questioned by customs regarding classification. Ignoring parameters such as electrode type and power, affecting customs assessment of equipment value. False declaration of brand and model, which may trigger intellectual property disputes or administrative penalties. Use filled in too vaguely, without distinguishing smelting, melting, or laboratory use, affecting subheading determination.

The core basis for classification is the Import and Export Tariff and the HS Explanatory Notes. The key to classifying electric arc furnaces under 851430 lies in their heating principle being arc heating, i.e., using the heat of an electric arc generated between electrodes and the charge for melting or heating. According to Chapter 85 notes, electric furnaces are classified by heating method, with electric arc furnaces listed alongside resistance furnaces and induction furnaces. It should also be noted that if equipment has multiple heating methods, the primary heating method shall prevail. In addition, the industrial or laboratory use of electric arc furnaces is also a necessary condition; household appliances are not classified under this heading. 851410 Resistance Furnaces: Resistance furnaces heat by resistance heating elements, such as box-type resistance furnaces and tube-type resistance furnaces, with relatively lower heating temperatures and no arc generation. Electric arc furnaces use high-temperature arcs for melting and have a structure containing electrodes. 851420 Induction Furnaces: Induction furnaces use electromagnetic induction to make the charge itself generate heat, with no electrodes, typically used for melting and heat treatment. Electric arc furnaces have electrodes and rely on arc radiant heat; the heating principles and structures are different. 851490 Parts: 851490 covers parts of electric furnaces, such as electrodes, furnace shells, etc. If electric arc furnace parts are imported separately, they should be classified under 851490, not the complete machine 851430. 845410 Steelmaking Converters: Converters are steel smelting equipment but use chemical energy (oxygen blowing) rather than electrical energy, classified under Chapter 84. Electric arc furnaces are electrometallurgical equipment, classified under Chapter 85. 851531 Arc Welding Equipment: Arc welding equipment is used for welding, classified under 851531, while electric arc furnaces are used for melting, classified under 851430. Although both use electric arcs, their uses and functions are different. Is the electric arc used as the primary heating source? Is it used for industrial or laboratory melting/heating? Does it include typical structures such as electrodes and a furnace body? Is it confused with resistance furnaces or induction furnaces? Is the complete machine imported separately rather than parts?

How are electric arc furnaces and induction furnaces distinguished in HS codes? Electric arc furnaces are classified under 851430, and induction furnaces under 851420. The core difference lies in the heating principle: electric arc furnaces use the heat of an electric arc between electrodes and the charge, and have electrodes; induction furnaces use electromagnetic induction to make the charge itself generate heat, with no electrodes. The heating principle and electrode type should be clearly stated in the declaration. How are parts of electric arc furnaces classified? Dedicated parts of electric arc furnaces, such as electrodes, furnace shells, tilting mechanisms, etc., if imported separately, should be classified under 851490. However, if the parts themselves belong to other headings (such as graphite electrodes under 8545), they are classified according to the specific material. Complete machines and parts must be declared separately. Are small laboratory electric arc furnaces also classified under 851430? Yes, as long as they are industrial or laboratory electric arc furnaces, regardless of size, they are classified under 851430. However, if they are for household or similar purposes, they are not classified under this heading. Laboratory equipment requires proof of use. How should power be filled in the declaration elements for electric arc furnaces? Power should be filled in as rated power or transformer capacity, usually in MVA (megavolt-amperes) or kW (kilowatts). For example, "50MVA." Power is an important reference for customs valuation and classification and must be consistent with the actual product. How are imported second-hand electric arc furnaces classified? Second-hand electric arc furnaces are still classified under 851430, but attention must be paid to customs regulatory requirements for used mechanical and electrical products, which may involve pre-shipment inspection, licenses, etc. The declaration should truthfully indicate "second-hand" and the condition rate. How can the tariff rate for electric arc furnaces be checked? It can be checked through the General Administration of Customs website, China International Trade Single Window, or the Import and Export Tariff. Tariff rates may vary due to trade agreements, country of origin, and other factors; it is recommended to refer to the latest tariff. Preferential rates may differ for different countries of origin. What regulatory documents are required for exporting electric arc furnaces? Generally, no special documents are required for export, but if dual-use items or technology exports are involved, relevant licenses must be obtained. Specific requirements can be consulted with the local customs or commerce department. Regarding export tax rebates, the rebate rate corresponding to the HS code should be confirmed. What are the consequences of incorrect classification of electric arc furnaces? Incorrect classification may lead to supplementary taxes, fines, downgrading, and other administrative penalties, and in serious cases may be suspected of smuggling. It is recommended that enterprises obtain advance classification rulings or consult professional customs brokers to ensure accurate declaration.
