Chapter 85 covers electric motors, electrical equipment and their parts; 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 a wide range of fields including power generation, power transformation, power consumption, communications, and consumer electronics. As industrial equipment that uses the principle of electromagnetic induction for heating, the core components of induction furnaces involve electrical control and energy conversion, and therefore they are classified under this chapter. Heading 8514 includes industrial or laboratory electric resistance heated furnaces and ovens (including those functioning by induction or dielectric loss), and other industrial or laboratory equipment for the heat treatment of materials by induction or dielectric loss. This heading mainly covers industrial equipment that uses electrical energy for heating, including induction furnaces, resistance furnaces, microwave furnaces, etc., but excludes household appliances (such as household microwave ovens classified under 8516) or welding equipment (classified under 8515). The first 2 digits, 85: indicate Chapter 85, namely electric motors, electrical equipment and their parts. Digits 3-4, 14: indicate heading 8514, namely industrial or laboratory electric furnaces and ovens. Digits 5-6, 20: indicate subheading 851420, specifically furnaces and ovens functioning by induction or dielectric loss. Among these, induction furnaces use the principle of electromagnetic induction to generate eddy currents in the metal charge for heating and melting, while dielectric loss furnaces use high-frequency electric fields to heat non-conductive materials. This subheading clearly distinguishes the heating principle, making it easier for customs to classify according to technical parameters. Induction furnaces heat through the principle of electromagnetic induction, belong to electric heating equipment, and are used in industry or laboratories, and therefore are classified under 8514. They differ from resistance heated furnaces (851410) because their heating principle is induction rather than resistance; they also differ from other electric furnaces (851430), such as electric arc furnaces. In addition, they are not classified under 8515 welding equipment because their main function is melting or heating, not welding.

Product name: Fill in the Chinese and English names of the commodity, which should accurately reflect the type of equipment, such as "induction melting furnace", "induction heating furnace", etc. Use: Explain the application field of the equipment, such as "used for iron and steel melting", "used for metal heat treatment", etc., and it must be specific to an industrial or laboratory scenario. Heating principle: Clearly indicate "induction heating" or "dielectric loss heating"; this is the key determining factor for classification under 851420. Brand: Fill in the equipment brand (if there is no brand, fill in "none"), used for customs intellectual property recordation verification. Model: Fill in the model specified by the manufacturer, which should reflect the equipment specifications (such as power, capacity). Power: Fill in the rated power of the equipment (kilowatts or megawatts), which affects equipment classification and regulatory conditions. Operating frequency: Fill in the operating frequency of the induction furnace (such as power frequency, medium frequency, high frequency); the frequency range affects equipment characteristics. Brand type: Fill in the brand type according to customs requirements, such as "foreign brand (OEM production)", "domestic brand", etc. Product name: Medium-frequency induction melting furnace; Use: Used for cast iron melting; Heating principle: Induction heating; Brand: ABC; Model: MF-500; Power: 500kW; Operating frequency: 1000Hz; Brand type: Foreign brand (OEM production). Incorrectly classifying an induction furnace under 851410 (resistance heated furnace) because the heating principle was not accurately described. Ignoring the declaration of operating frequency, causing customs to question the actual working principle of the equipment. Incorrect entry of brand type, such as filling in OEM production as domestic brand, triggering subsequent verification.

The core determining basis for classification is the heating principle and use of the equipment. According to HS notes, subheading 851420 covers furnaces and ovens functioning by induction or dielectric loss, mainly for industrial or laboratory use. Induction heating uses electromagnetic induction to generate eddy currents and heat within the object being heated, while dielectric loss heating uses a high-frequency electric field to heat non-conductive materials. If the equipment uses resistance heating, it should be classified under 851410; if it uses other principles (such as electric arc), it should be classified under 851430. In addition, it is necessary to confirm whether the equipment is used in industry or laboratories, rather than household use. 851410 Resistance heated furnaces and ovens: Resistance heated furnaces generate heat through resistance elements, and the heat is transferred to the workpiece; induction furnaces generate heat directly within the workpiece through electromagnetic induction. The heating principle must be clearly stated at declaration. 851430 Other electric furnaces and ovens: Includes electric arc furnaces, electron beam furnaces, etc., whose heating principles differ from induction furnaces. Induction furnaces must be clearly identified as using induction or dielectric loss heating. 851511 Soldering irons and guns for brazing or welding: Welding equipment is used to join metals, while induction furnaces are used for melting or heating, with different functions. However, induction welding equipment may be classified under 8515, and judgment should be based on the main function. 851680 Electric resistance heaters: Electric resistance heaters are individual electric heating elements, while induction furnaces are complete heating equipment. If induction coils and other parts are imported, they should be classified under 851490. 850431 Transformers: Induction furnaces may contain transformer components, but the complete machine is still classified under 851420. If transformers are imported separately, they are classified under 8504. Is it clearly stated that the equipment uses induction or dielectric loss heating? Is the equipment used in industry or laboratories, rather than household use? Have sufficient technical parameters (power, frequency) been provided? Is it clearly distinguished from resistance furnaces, electric arc furnaces, etc.? Are declaration elements such as brand and model complete and accurate?

How are induction furnaces and resistance furnaces distinguished in HS codes? Induction furnaces are classified under 851420, and resistance furnaces under 851410. The key difference lies in the heating principle: induction furnaces use electromagnetic induction to make the workpiece itself generate heat, while resistance furnaces generate heat through resistance elements and then conduct it. At declaration, an explanation of the heating principle should be provided, and technical materials if necessary. What declaration elements are required for importing induction furnaces? Product name, use, heating principle, brand, model, power, operating frequency, brand type, etc. are required. Among these, the heating principle and use are key to classification, while power and frequency help customs confirm equipment characteristics. How are parts of induction furnaces classified? If dedicated parts of induction furnaces (such as induction coils and control cabinets) are imported separately, they should be classified under 851490. However, if the parts themselves are general-purpose components (such as transformers), they are classified under the corresponding heading. Are household induction furnaces classified under 851420? No. 851420 applies only to industrial or laboratory induction furnaces. Household induction furnaces (such as induction cookers) are classified under 8516. The criterion is use, not power size. How can the tariff rate for induction furnaces be checked? Tariff rates must be determined according to the importing country, country of origin, trade agreements, etc. They can be checked in customs tariff schedules or through official databases, such as China Customs' "Internet + Customs" platform. Rates may change, so the latest published version should be used. What certifications are required for exporting induction furnaces to the EU? Exporting to the EU requires CE certification, including the Low Voltage Directive (LVD), Electromagnetic Compatibility Directive (EMC), etc. The specific requirements depend on equipment parameters and use. It is recommended to communicate with certification bodies in advance. Are HS codes for induction furnaces consistent across countries? The first 6 digits of the HS code are uniform internationally, but countries may have different subdivisions in later digits. For example, the U.S. HTSUS may have further subdivisions under 851420. When exporting, the destination country's code must be confirmed. If an induction furnace is used for welding, which code should it be classified under? If the main function of the induction furnace is welding, it should be classified under 8515 (welding equipment). However, if it has both melting and welding functions, judgment should be based on the main function. It is recommended to provide detailed technical explanations.
