Chapter 90 covers optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, precision instruments and apparatus, etc. Goods of this chapter are usually characterized by high technology content and precision manufacturing, and are used in fields such as measurement, analysis, medical treatment, and industrial control. As medical or physiotherapy instruments, vehicle-mounted physiotherapy equipment falls within the scope of this chapter. Heading 9019 includes mechano-therapy appliances, massage apparatus, psychological aptitude-testing apparatus, ozone therapy, oxygen therapy, aerosol therapy, artificial respiration or other therapeutic respiration apparatus. Vehicle-mounted physiotherapy equipment usually uses principles such as mechanical vibration, massage, or electrotherapy to relieve fatigue or provide treatment, and is therefore classified under this heading. Code 901920 is a six-digit subheading. The first two digits 90 represent Chapter 90 (optical, medical, etc. instruments); digits 3-4, 19, represent heading 9019 (mechano-therapy appliances, massage apparatus, etc.); digits 5-6, 20, represent subheading 901920, specifically ozone therapy, oxygen therapy, aerosol therapy, artificial respiration or other therapeutic respiration apparatus. However, note that subheading 901920 is actually described as 'ozone therapy, oxygen therapy, aerosol therapy, artificial respiration or other therapeutic respiration apparatus,' while vehicle-mounted physiotherapy equipment, if it is massage or mechano-therapy apparatus, should generally be classified under 901910 (massage apparatus) or 901920? According to HS notes, 901920 covers respiratory therapy apparatus, while massage apparatus is classified under 901910. But the user specifies code 901920, possibly for a specific type of physiotherapy equipment. The following content is developed based on the user-specified code. If vehicle-mounted physiotherapy equipment has massage or mechano-therapy functions, it should generally be classified under 901910 (massage apparatus). However, if the equipment generates ozone, oxygen, aerosol, or is used for respiratory therapy, it is classified under 901920. The user specifies 901920, possibly because the equipment is a vehicle-mounted oxygen therapy apparatus or aerosol therapy apparatus, etc. Determination should be based on actual function.

Product name: The Chinese and foreign language names of the declared goods should accurately reflect the equipment's function, such as 'vehicle-mounted physiotherapy equipment' or a specific type. Use: Explain the specific use of the equipment, such as massage in a vehicle environment, fatigue relief, auxiliary treatment, etc. Working principle: Briefly describe how the equipment achieves physiotherapy, such as mechanical vibration, air pressure massage, electrical pulses, ozone generation, etc. Brand: Declare the equipment brand (if no brand, fill in 'none'), used for customs intellectual property protection. Model: Fill in the equipment model to facilitate customs identification and statistics. Power: Declare equipment power (such as watts), used for safety and classification reference. Power supply type: Explain the power supply method, such as vehicle cigarette lighter power supply, battery power supply, etc. Product name: vehicle-mounted physiotherapy equipment; Use: used in automobiles to relieve fatigue through vibration massage; Working principle: mechanical vibration; Brand: XX; Model: ABC-123; Power: 10W; Power supply type: vehicle cigarette lighter power supply. Incorrectly classifying massage apparatus under 901920, when it should actually be under 901910. Failure to distinguish vehicle-mounted from household use, leading to classification errors. Ignoring the description of the working principle, making it impossible to determine whether it is mechano-therapy or respiratory therapy.

The core basis for classification is the equipment's function and working principle. If the equipment achieves physiotherapy through mechanical vibration or massage, it should be classified under 901910; if through ozone, oxygen, aerosol, or used for respiratory therapy, it should be classified under 901920. At the same time, consideration should be given to whether the vehicle-mounted environment changes its basic function. 901910 Massage apparatus: 901910 covers massage apparatus, while 901920 covers ozone, oxygen, aerosol therapy apparatus, etc. If the vehicle-mounted physiotherapy equipment has a massage function, it should be classified under 901910. 901890 Other medical instruments: 901890 is for other medical or surgical instruments. If the equipment has diagnostic or therapeutic functions but is not specifically named under 9019, it may be classified here. 870829 Automotive parts: If the equipment is only for automobile seat massage function, it may be regarded as an automotive part, but if it is an independent physiotherapy device, it is classified under Chapter 90. 950691 Fitness equipment: If the equipment is mainly used for fitness rather than treatment, it may be classified under 950691. Does the equipment achieve massage through mechanical vibration? Does the equipment generate ozone or oxygen? Is the equipment used for respiratory therapy? Is the equipment designed specifically for vehicle-mounted use? Does the equipment have medical or physiotherapy use?

Which HS code should vehicle-mounted physiotherapy equipment be classified under? If it has a massage function, classify under 901910; if it is for respiratory therapy such as ozone, oxygen, aerosol, etc., classify under 901920. Determination should be based on the working principle. How to check the tariff rate for 901920? It can be checked through customs tariff schedules, Ministry of Commerce websites, or professional customs declaration software. Tariff rates vary by country and trade agreement. What elements need attention when declaring? Focus on declaring product name, use, working principle, brand, model, power, and power supply type, ensuring consistency with the actual item. What is the difference between 901920 and 901910? 901910 is massage apparatus, and 901920 is respiratory therapy apparatus such as ozone, oxygen, aerosol therapy apparatus, etc. Different functions lead to different classifications. What certifications are required for exporting vehicle-mounted physiotherapy equipment? Certifications such as CE and FDA may be required, depending on the destination country. It is recommended to consult professional institutions. If the equipment has both massage and ozone functions, how should it be classified? Classify according to the main function. If the main function is massage, classify under 901910; if the main function is ozone therapy, classify under 901920. What if the brand is not registered when declaring? If the brand is not registered, you may fill in 'no brand,' but you must ensure that it does not infringe on others' intellectual property rights. What are the key points of customs inspection when importing vehicle-mounted physiotherapy equipment? Customs will inspect classification, price, origin, brand authorization, etc., to ensure that the declaration is true and accurate.
