Chapter 85 is the chapter in the HS classification system concerning electrical machinery, equipment and parts thereof, covering power generation, transformation, energy storage, power-consuming equipment and appliances. This chapter includes electric motors, generators, transformers, batteries, household appliances, electronic components, etc., but excludes assembled complete machines or unassembled optical elements. Magnetrons, as electronic tubes that generate microwaves, belong to the electronic tube category of products under this chapter. Heading 8540 covers thermionic tubes, cold cathode tubes or photocathode tubes (including gas-filled tubes, vacuum tubes, mercury arc rectifier tubes, etc.), as well as parts of the aforesaid tubes. It specifically includes semiconductor devices such as diodes, transistors, thyristors, photocells, as well as microwave tubes such as magnetrons and klystrons. This heading mainly targets electronic devices that operate using electron emission or semiconductor characteristics. HS code 854071 is a six-digit subheading: the first two digits 85 represent Chapter 85 (electrical machinery, equipment and parts thereof); digits 3-4, 40, represent heading 8540 (thermionic tubes, cold cathode tubes or photocathode tubes); digits 5-6, 71, represent subheading 854071, specifically referring to magnetrons. A magnetron is a vacuum electron tube that uses a magnetic field to control electron movement to generate microwaves, commonly used in microwave ovens, radar and other equipment. This subheading further refines the specific product types under heading 8540. Magnetrons belong to the category of thermionic tubes. Their operating principle is based on electrons moving in magnetic and electric fields to generate microwave oscillations, which conforms to the definition of thermionic tubes under heading 8540. They differ from the semiconductor devices of heading 8541 (such as diodes and transistors), and also differ from the integrated circuits of heading 8542, because magnetrons are vacuum electron tubes, not semiconductor devices. Therefore, they are classified under 854071.

Product name: The Chinese and foreign language names of the declared commodity, which should accurately reflect the product's attributes, such as "magnetron" or "Magnetron". Use: Explain the specific application scenarios of the magnetron, such as for microwave ovens, industrial heating, radar systems, etc. Brand: Fill in the manufacturer or brand name, such as Panasonic, LG, Toshiba, etc. Model: Declare the model specifications of the magnetron, such as 2M261-M32, etc., used to uniquely identify the product. Power: The output power of the magnetron, usually in watts (W), such as 1000W. Frequency: The operating frequency of the magnetron, usually 2450MHz or another specified frequency. Brand type: Fill in the brand type according to customs regulations, such as "foreign brand (OEM production)", "domestic brand", etc. Export benefit status: State whether export tariff preferences are enjoyed, such as "not enjoyed" or "enjoyed". Product name: Magnetron; Use: For microwave ovens; Brand: Panasonic; Model: 2M261-M32; Power: 1000W; Frequency: 2450MHz; Brand type: Foreign brand (OEM production); Export benefit status: Not enjoyed. Mistakenly classifying magnetrons under 8541 semiconductor devices, leading to incorrect tax rates and regulatory conditions. Inaccurate declaration of power and frequency, which may trigger customs questions or inspection. Ignoring brand type and export benefit status, affecting tariff collection and trade statistics.

The core basis for classification is the product's operating principle and structure. A magnetron is a vacuum electron tube that uses magnetic and electric fields to cause electrons to generate microwave oscillations, belonging to the category of thermionic tubes. According to General Interpretative Rule 1 of the HS, it should be classified under heading 8540. If it is a semiconductor microwave device (such as a microwave transistor), it is classified under 8541. Therefore, it must be confirmed whether the product has a vacuum tube structure rather than being a semiconductor device. 854110 Diodes: Diodes are semiconductor devices that operate using PN junction characteristics, while magnetrons are vacuum electron tubes that use the movement of electrons in a vacuum. 854121 Transistors: Transistors are semiconductor devices used for amplification or switching, while magnetrons are used to generate microwaves, with different principles and structures. 854130 Thyristors: Thyristors are semiconductor switching devices, while magnetrons are microwave oscillator tubes, with different functions and application fields. 854160 Mounted piezo-electric crystals: Piezo-electric crystals use the piezoelectric effect, while magnetrons use the movement of electrons in a magnetic field; the two have different principles. 854320 Microwave generators: Microwave generators may contain magnetrons and other components; if they are complete equipment, they are classified under 8543, while magnetrons alone are classified under 854071. Is the product a vacuum electron tube structure? Does it use a magnetic field to control electrons to generate microwaves? Is it used in microwave ovens, radar and other equipment? Is it distinguishable from semiconductor microwave devices? Is it declared separately rather than as a complete machine?

What is the difference in HS codes between magnetrons and complete microwave ovens? A magnetron is the core component of a microwave oven and is classified under 854071 when declared separately; a complete microwave oven is classified under 851650. If a magnetron is declared together with a complete machine, it should be classified as a complete machine. How can it be determined whether a magnetron belongs to 854071? The key is whether it is a vacuum electron tube and used to generate microwaves. If it is a semiconductor device or integrated circuit, it is classified under 8541 or 8542. Product manuals and technical parameters can be referred to. What are the common classification errors when declaring magnetrons? Common errors include mistakenly classifying them under 8541 semiconductor devices, 8543 microwave equipment, or failing to distinguish between parts and complete machines. They should be classified strictly according to operating principle and structure. In the declaration elements for magnetrons, must power and frequency be provided? Yes, power and frequency are important technical parameters of magnetrons and help customs confirm the product's attributes. Truthful declaration is recommended to avoid inspection risks. What regulatory documents are required for importing magnetrons? Usually no special regulatory documents are required, but if radio transmitting equipment is involved, radio type approval may be required. Specific requirements can be checked with the General Administration of Customs or by consulting a customs broker. How can the tariff rate for magnetrons be checked? You can log on to the website of the General Administration of Customs of China or use a customs commodity code query tool and enter 854071 to check the latest tariff rate. Tariff rates may vary depending on trade agreements and country of origin. What should be noted when selling magnetrons through cross-border e-commerce? It is necessary to ensure that the product complies with the technical standards of the destination country, such as CE and FCC certification. Accurately fill in the HS code and elements during declaration to avoid undervaluation or incorrect classification. What are the main brands and models of magnetrons? Common brands include Panasonic, Toshiba, LG, Samsung, etc., with models such as 2M261-M32 and OM75S. Different models may have different power and frequency, and they must be listed specifically during declaration.
