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 a wide range of goods from household appliances to precision electronic components. Radar equipment, as an electronic device that uses electromagnetic waves for detection and positioning, has its core components classified as electrical equipment and is therefore classified under this chapter. Heading 8526 specifically covers radar apparatus, radio navigational aid apparatus and radio remote control apparatus. Among these, radar apparatus refers to devices that detect the presence, distance, speed, azimuth and other information of targets by transmitting and receiving radio waves, and is widely used in military, aviation, maritime, meteorological, transportation and other fields. This heading is further subdivided: 8526.10 for radar apparatus, 8526.91 for radio navigational aid apparatus, and 8526.92 for radio remote control apparatus. Code 852610 is a six-digit subheading. The first two digits 85 indicate 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, 26, indicate heading 8526 (radar apparatus, radio navigational aid apparatus and radio remote control apparatus). Digits 5-6, 10, indicate subheading 8526.10, i.e., radar apparatus. This subheading may be further subdivided under individual national tariff schedules, but at the international level it only goes to six digits. The core function of radar apparatus is radio detection and ranging, which distinguishes it from radio navigational aid apparatus (aiding navigation) and radio remote control apparatus (remote control). Radar apparatus is classified under 8526.10 because it is essentially an electronic device that uses the principle of radio wave reflection for target detection and positioning. It differs from wireless communication equipment (such as 8517), which is used for transmitting information; it also differs from radio navigational aid apparatus (8526.91), which is used for receiving navigation signals to determine position; and it further differs from radio remote control apparatus (8526.92), which is used for sending control commands. The core of radar apparatus lies in actively transmitting and receiving echoes to achieve detection.

Product Name: The specific name of the declared commodity, such as "marine navigation radar", "weather radar", "traffic speed measurement radar", etc., which must be consistent with the actual product. Use: Explain the specific application scenario of the radar, such as military, aviation, maritime, meteorological, transportation, security, etc. Operating Principle: Briefly describe the radar's operating mode, such as pulse Doppler, continuous wave, synthetic aperture, etc. Brand: The brand name of the declared commodity; if there is no brand, "no brand" may be entered. Model: The specific model of the declared commodity, which must be consistent with the actual nameplate. Operating Frequency: The frequency range of the radio waves transmitted by the radar, such as X-band, S-band, etc. Transmit Power: The peak transmit power or average power of the radar, usually in watts or kilowatts. Whether It Has an Antenna: Indicate whether the radar includes an antenna; if the antenna is imported separately, it should be classified under another code. Product Name: Marine navigation radar; Use: For ship navigation and collision avoidance; Operating Principle: Pulse Doppler; Brand: FURUNO; Model: FR-8065; Operating Frequency: X-band (9.4GHz); Transmit Power: 6kW; Whether It Has an Antenna: Yes. Note: This equipment is a complete radar system, including the antenna unit, transceiver unit and display unit. Misdeclaring radio navigational aid apparatus as radar apparatus; the two have different functions. Failing to provide operating frequency and transmit power, leading to classification disputes. Declaring the radar antenna separately; it should be classified under 8529.10.

The core criterion for classification is whether the commodity uses the principle of radio wave reflection to achieve target detection and positioning. Radar apparatus must include a device for transmitting and receiving radio waves and must be able to obtain target information through echo analysis. If it only receives radio waves for navigation (such as a GPS receiver), it is classified under 8526.91; if it is used to send control commands (such as a drone remote controller), it is classified under 8526.92. In addition, radar apparatus may be a complete system or a separately imported radar main unit, but antennas are usually classified separately. 852691 Radio navigational aid apparatus: Radio navigational aid apparatus determines position by receiving external navigation signals (such as GPS, GLONASS) and does not actively transmit detection waves; radar apparatus actively transmits and receives echoes. 852692 Radio remote control apparatus: Radio remote control apparatus is used to send control commands to operate equipment remotely and is not used to detect targets; radar apparatus is used for detection and positioning. 851762 Wireless communication equipment: Wireless communication equipment is used to transmit voice, data and other information and does not involve target detection; the core function of radar apparatus is detection. 852990 Parts of radar apparatus: If parts of radar apparatus (such as antennas, transceiver modules) are imported separately, they are classified under 8529.90; complete radar apparatus is classified under 8526.10. 901580 Other measuring instruments: Some distance measuring equipment that does not use the radio wave principle (such as laser rangefinders) is classified under 9015, whereas radar apparatus must use radio waves. Does the commodity actively transmit radio waves? Does it use echoes for target detection? Does it include a complete transmit-receive system? Is it used for navigation or remote control? Is the antenna imported together with the main unit?

How are radar apparatus and radio navigational aid apparatus distinguished? Radar apparatus actively transmits radio waves and receives echoes to detect targets; radio navigational aid apparatus only receives external navigation signals (such as GPS) to determine its own position. If a device can both navigate and detect, it is usually classified according to its primary function. What declaration elements are required for importing radar apparatus? Product name, use, operating principle, brand, model, operating frequency, transmit power, whether it has an antenna, etc. are required. Some countries may also require a technical parameter sheet or manual. Under which code should a radar antenna imported separately be classified? As a dedicated part of radar apparatus, if a radar antenna is imported separately, it should be classified under 8529.10 (antennas and parts thereof for radar apparatus and radio navigational aid apparatus). What is the difference in classification between radar apparatus and wireless communication equipment? Wireless communication equipment (such as 8517) is used to transmit information and does not involve target detection; radar apparatus (8526.10) is used for detection and positioning. If a device has both communication and detection functions, it must be determined according to its primary function. How can I check the import tariff rate for radar apparatus? Tariff rates vary by country and change over time. It is recommended to check the customs official website of the importing country or use an official tariff query tool, entering HS code 852610 and the country of origin to obtain the latest tariff rate. After radar apparatus is classified under 8526.10, are there other regulatory conditions to consider? Yes. Some radar apparatus may involve export controls, radio frequency approval or military-use restrictions, and the relevant regulations of the importing country should be understood in advance. If radar apparatus has a GPS function, how should it be classified? If the primary function of the radar apparatus is detection and GPS is only an auxiliary function, it is still classified under 8526.10; if GPS is the primary function, it is classified under 8526.91. What is the classification boundary between parts of radar apparatus and complete machines? Complete machines are classified under 8526.10; dedicated parts (such as antennas, transceiver modules) imported separately are classified under 8529.90. However, if the parts are imported together with the complete machine and have already been assembled, they are classified as the complete machine.
