Chapter 90 covers optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, and precision instruments and apparatus; parts and accessories thereof. Goods in this chapter generally have characteristics of high technology content and high added value, and are widely used in fields such as medical diagnosis, industrial inspection, and scientific research experiments. X-ray equipment, as a device that uses radiation for fluoroscopic examination, whether used for medical or industrial purposes, is classified in this chapter. Heading 9022 includes apparatus based on the use of X-rays or of alpha, beta or gamma radiations, whether or not for medical, surgical, dental or veterinary uses, including X-ray tubes, other X-ray generators, high tension generators, control panels and desks, screens, examination or treatment tables, chairs and the like. This heading covers both medical diagnostic equipment and industrial non-destructive testing equipment. The first 2 digits 90: Chapter 90, representing optical, medical and other precision instruments and equipment. The 3rd-4th digits 22: Heading 9022, specifically referring to apparatus based on the use of X-rays and similar radiations. The 5th-6th digits 11: Subheading 902211, further limited to X-ray equipment 'for medical, surgical, dental or veterinary uses'. Therefore, the complete meaning of 902211 is: X-ray application equipment specifically for medical, surgical, dental or veterinary fields. If a vehicle-mounted X-ray machine is used for medical diagnosis (such as a mobile medical examination vehicle), it is classified under this subheading. Although the vehicle-mounted X-ray machine is installed on a vehicle, its core function is to generate X-rays for medical imaging examination, which conforms to the description of 902211 'medical X-ray equipment'. It is not classified under 8705 (special purpose vehicles) because the vehicle is only a carrier, and the equipment itself is the basis for classification; nor is it classified under 902219 (other X-ray equipment) because it is explicitly used for medical purposes.

Product Name: The Chinese and English names of the declared goods, which should accurately reflect the purpose and type of the equipment, such as 'vehicle-mounted X-ray machine' or 'mobile medical X-ray diagnostic system'. Purpose: Clearly state the usage scenario of the equipment, such as medical diagnosis, surgery, dental examination or veterinary application, which must correspond to subheading 902211. Working Principle: Briefly describe the method by which the equipment generates X-rays, such as X-ray tube, high voltage generator, and the imaging method (digital or film). Brand: Declare the brand or manufacturer name of the equipment; if there is no brand, indicate 'no brand'.

Vehicle-mounted: Declare whether the equipment is installed on a vehicle, and whether the vehicle is imported together with the equipment as a whole. Main Components: List the main components of the equipment, such as X-ray tube, detector, image processing system, control console, etc. Power: Declare the rated power or tube voltage of the X-ray generator, in kilowatts or kilovolts. Product Name: Vehicle-mounted X-ray machine (mobile medical X-ray diagnostic system); Purpose: Medical diagnosis, used for chest X-ray examination in mobile medical vehicles; Working Principle: Generates X-rays through an X-ray tube, which penetrate the human body and are received by a digital detector for imaging; Brand: GE; Model: Optima XR220amx; Vehicle-mounted: Yes, installed on a medical examination vehicle, vehicle and equipment imported together; Main Components: X-ray tube, high voltage generator, digital flat panel detector, image processing workstation, control console; Power: 32kW. Misreporting medical use as industrial inspection, leading to incorrect classification under 902219. Ignoring the 'vehicle-mounted' feature, failing to explain the relationship between the vehicle and the equipment, which may be incorrectly classified under 8705. Failure to provide power or working principle, making it impossible to prove the equipment is X-ray application equipment.

The core basis for classification is the purpose and function of the equipment. According to HS Notes, 902211 specifically refers to X-ray equipment for medical, surgical, dental or veterinary uses. If a vehicle-mounted X-ray machine is used for medical diagnosis, it conforms to the description of this subheading. If the equipment is used for industrial non-destructive testing or security inspection, it should be classified under 902219. If the vehicle itself constitutes a special purpose vehicle (such as a medical vehicle equipped with fixed equipment), and the equipment and vehicle are inseparable, it may be classified as a vehicle, but generally the X-ray machine as standalone equipment is still classified under 9022. 902219 Other X-ray equipment: Used for non-medical purposes, such as industrial flaw detection, security inspection, scientific research, etc. If the vehicle-mounted X-ray machine is used for industrial inspection, it is classified under this code. 870590 Other special purpose vehicles: When the vehicle itself is the main functional carrier and the equipment and vehicle form an inseparable whole, it may be classified under this code. But generally the X-ray machine as standalone equipment is still classified under 9022. 902212 Computed tomography equipment: Specifically refers to CT scanners, which use X-rays for tomographic imaging. If the vehicle-mounted X-ray machine is CT equipment, it should be classified under 902212. 902213 Other X-ray equipment for dental use: Specifically for dental diagnosis, such as oral X-ray machines. If the vehicle-mounted X-ray machine is used for dentistry, it is classified under this code. 902214 Other X-ray equipment for medical, surgical or veterinary use: This is a residual subheading for other medical X-ray equipment. However, 902211 explicitly includes medical use, so general medical X-ray machines are preferentially classified under 902211. Is the equipment used for medical, surgical, dental or veterinary purposes? Does the equipment use X-rays as its main working principle? Is the equipment installed on a vehicle? Is the vehicle imported together with the equipment? Does the equipment have independent functions, or is it inseparable from the vehicle? Have sufficient declaration elements been provided to support classification?

What is the difference in HS codes between vehicle-mounted X-ray machines and mobile X-ray machines? Both may be classified under 902211 as long as they are used for medical diagnosis. The difference is that vehicle-mounted X-ray machines are usually installed on vehicles, which may involve the overall classification issue of the vehicle and equipment. If the equipment can be used independently, it is still classified as an X-ray machine; if it forms an inseparable whole with the vehicle, it may be classified as a special purpose vehicle. How to determine whether a vehicle-mounted X-ray machine is for medical or industrial use? Mainly look at the designed purpose and actual application scenario of the equipment. Medical use usually has a medical device registration certificate and is used for human diagnosis; industrial use is for non-destructive testing, such as weld inspection. When declaring, supporting documents such as purpose description and technical parameters should be provided. If a vehicle-mounted X-ray machine has both medical and industrial inspection functions, how should it be classified? Classify according to the primary use. If the primary use is medical, classify under 902211; if the primary use is industrial, classify under 902219. If it cannot be determined, refer to customs advance classification rulings or consult professional classification personnel. What special documents are required for importing vehicle-mounted X-ray machines? In addition to conventional customs declaration documents, X-ray machines for medical use may require medical device registration certificates, radiation safety licenses, etc. Specific requirements are subject to customs and relevant authorities. How to check the tariff rate for vehicle-mounted X-ray machines? It can be checked through the website of the General Administration of Customs, the Chinese Customs Import and Export Tariff, or by consulting a customs broker. Tariff rates are adjusted according to national policies, and the latest tariff schedule should be used as the basis. If the vehicle and X-ray machine are imported separately, how should the HS codes be declared? The vehicle is classified as a vehicle (such as 8705), and the X-ray machine is classified under 902211. If imported together and forming a whole, classification should be determined based on the primary function. What is the difference between 902211 and 902212? 902211 covers all medical X-ray equipment, including general X-ray machines; 902212 specifically refers to computed tomography equipment (CT). If the vehicle-mounted X-ray machine is CT equipment, it should be classified under 902212. What are the consequences of filling in the brand and model incorrectly during declaration? It may lead to classification errors, tax evasion, or affect customs statistics, and may even result in administrative penalties. It is recommended to fill in the brand and model truthfully and accurately.
