Chapter 90 covers optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, precision instruments and apparatus; parts and accessories thereof. This chapter has a broad scope, covering everything from eyeglasses and microscopes to medical imaging equipment and industrial measuring instruments. The core characteristic is that these goods are typically high-precision and technology-intensive, used for professional purposes such as measurement, inspection, analysis, and medical treatment. This chapter does not include ordinary mechanical appliances (Chapter 84) or electrical equipment (Chapter 85), but does include electronic medical equipment such as X-ray machines and radiotherapy equipment. Heading 9022 covers 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 radiography or radiotherapy apparatus, X-ray tubes, high tension generators, control panels and desks, screens, examination or treatment tables, chairs and the like. This heading includes both medical diagnostic equipment (such as CT scanners and X-ray machines) and industrial non-destructive testing equipment, security inspection equipment, etc. The key determination is whether the equipment uses X-rays or alpha, beta or gamma radiations for imaging, detection, or treatment. First 2 digits 90: indicates Chapter 90, covering optical, medical, and precision instruments and equipment. Digits 3-4, 22: indicates heading 9022, specifically for apparatus based on the use of X-rays and alpha, beta or gamma radiations. Digits 5-6, 29: indicates subheading 902229, specifically 'other apparatus based on the use of radiations for vehicle-mounted use,' i.e., equipment installed on vehicles that operates using radiations (X-rays or alpha, beta or gamma radiations), but excluding vehicle-mounted equipment exclusively for medical, surgical, dental or veterinary uses (those are classified under 9022.12 or 9022.14, etc.). This subheading covers vehicle-mounted radiation equipment for industrial inspection, security screening, flaw detection, etc. This commodity is vehicle-mounted radiation equipment, whose core function is to use radiations (such as X-rays or gamma rays) for detection, imaging or analysis, and is installed on vehicles for mobile use. Because it uses radiations, it is classified under heading 9022; because it is not exclusively for medical, surgical, dental or veterinary uses and is in vehicle-mounted form, it is classified under subheading 902229. If it were medical vehicle-mounted X-ray equipment, it should be classified under 9022.12 (for medical use); if it were non-vehicle-mounted industrial radiation equipment, it might be classified under 9022.19 or other subheadings.

Product Name: The Chinese and English names of the declared commodity, which should accurately reflect the equipment type, such as 'vehicle-mounted X-ray inspection equipment.' Use: Explain the specific application scenario of the equipment, such as industrial non-destructive testing, security screening, flaw detection, etc. Non-medical use must be clearly stated. Working Principle: Describe the type of radiation used by the equipment (X-rays, alpha, beta, gamma rays) and the imaging or detection method. Brand: Declare the equipment brand (such as Siemens, Philips, etc.). If no brand, write 'None.' Model: Declare the specific model to distinguish different specifications of equipment. Vehicle-Mounted: Clearly state whether the equipment is installed on a vehicle for use. If yes, write 'Yes'; otherwise write 'No.' Radiation Type: Specifically state the type of radiation used, such as X-rays, gamma rays, etc. Power: Declare the equipment power (such as kV, mA parameters) to assist in determining the equipment type. Customs declaration form example: Product Name: Vehicle-mounted X-ray industrial inspection equipment Use: For non-destructive testing of pipeline welds Working Principle: Uses X-ray penetration imaging for real-time defect analysis Brand: XX Model: XXX-2000 Vehicle-Mounted: Yes Radiation Type: X-ray Power: 200kV/5mA HS Code: 90222900 Declaration Elements: Product Name, Use, Working Principle, Brand, Model, Vehicle-Mounted, Radiation Type, Power Incorrectly classifying medical vehicle-mounted radiation equipment under this code; it should actually be classified under 9022.12. Failing to specify whether vehicle-mounted, leading to confusion with 9022.19 (other non-vehicle-mounted). Radiation type declared too generally, such as writing only 'radiation,' affecting classification accuracy.

Core classification criteria: 1) Whether the equipment operates using X-rays or alpha, beta, gamma radiations; 2) Whether it is exclusively for medical, surgical, dental or veterinary uses; 3) Whether it is installed on a vehicle as vehicle-mounted equipment. If all three conditions are met—uses radiations, non-medical use, and vehicle-mounted—then classify under 902229. If for medical use, even if vehicle-mounted, classify under 9022.12; if non-vehicle-mounted, classify under 9022.19 or other subheadings. 902212 Medical X-ray equipment: Exclusively for medical diagnosis or treatment, such as CT scanners and X-ray machines. Even if vehicle-mounted, classified under this code, whereas 902229 is for non-medical uses. 902219 Other non-medical X-ray equipment: Non-vehicle-mounted industrial or security X-ray equipment. 902229 emphasizes vehicle-mounted form; both have the same use but differ in installation method. 902214 Other medical alpha, beta, gamma radiation equipment: Medical gamma ray therapy equipment, etc. Classified under this code whether or not vehicle-mounted; 902229 is for non-medical vehicle-mounted. 902290 Other parts and accessories of heading 9022: Parts for 9022 equipment, such as X-ray tubes and control panels, whereas 902229 is complete vehicle-mounted equipment. 870590 Special purpose vehicles: Vehicles equipped with radiation equipment. If the equipment and vehicle form an integral whole, they may be classified as vehicles, but typically radiation equipment is separately classified under 902229. Does the equipment use X-rays or alpha, beta, gamma radiations? Is it exclusively for medical, surgical, dental or veterinary uses? Is it installed on a vehicle as vehicle-mounted equipment? Is it for non-medical purposes such as industrial or security screening? Does it form an inseparable whole with the vehicle?

Which HS code should vehicle-mounted X-ray security screening equipment be classified under? If vehicle-mounted and not exclusively for medical use, classify under 90222900. However, it must be confirmed that it uses X-rays and is not exclusively for medical use. If the equipment is integrated with the vehicle, it may be classified as a vehicle; consulting customs is recommended. Is medical vehicle-mounted X-ray equipment classified under 902229? No. Medical X-ray equipment, even if vehicle-mounted, should be classified under 90221200 (medical X-ray equipment). 902229 only applies to non-medical vehicle-mounted radiation equipment. How to distinguish between 902229 and 902219? 902219 is for non-vehicle-mounted other non-medical X-ray equipment; 902229 is for vehicle-mounted non-medical radiation equipment. The key difference is whether it is installed on a vehicle for use. How should 'Vehicle-Mounted' be filled in during declaration? If the equipment is permanently installed on a vehicle and used as the vehicle moves, write 'Yes'; if it is only portable and movable but not vehicle-mounted, write 'No.' Vehicle information or installation proof must be provided. Is vehicle-mounted gamma ray flaw detection equipment classified under 902229? Yes, if for non-medical use and vehicle-mounted, classify under 902229. Gamma rays are radiations, meeting heading 9022, and it is non-medical vehicle-mounted, so it is classified under this code. What are the export regulatory conditions for 902229? Radiation equipment may involve radiation safety regulation, requiring a radiation safety license. Export may require commodity inspection or dual-use item licenses. Specific requirements are subject to the latest customs regulations. How are parts of vehicle-mounted radiation equipment classified? If parts are exclusively for 9022 equipment, classify under 902290; if they are general-purpose parts, classify by material. However, complete vehicle-mounted equipment is classified under 902229. How to check the tax rate for 902229? Tax rates may change. The latest rates can be checked through the General Administration of Customs website, China International Trade Single Window, or by consulting a customs broker. It is recommended to rely on the system feedback at the time of actual declaration.
