Chapter 90 covers optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, and precision instruments and apparatus. Goods in this chapter generally have high technology content and high added value, and classification requires close attention to their functional principles and uses. Dental instruments, as an important branch of medical equipment, whether powered or not, are preferentially classified in this chapter rather than by material or as ordinary tools. Heading 9018 covers medical, surgical, dental or veterinary instruments and appliances, including scintigraphic apparatus, other electromedical apparatus and sight-testing instruments. Dental instruments, whether vehicle-mounted or combined with a vehicle, fall within this heading as long as their core function is dental diagnosis and treatment. The vehicle-mounted attribute does not change their essential classification as dental equipment. The first 2 digits 90 represent Chapter 90, i.e., optical, medical and other precision instruments and equipment; digits 3-4, 18, represent heading 9018, specifically medical, surgical, dental or veterinary instruments and appliances; digits 5-6, 49, represent subheading 901849, i.e., other dental instruments and appliances. This subheading covers dental instruments not specifically named, such as vehicle-mounted dental treatment units and portable dental machines. If it is a specifically named dental chair, etc., it may be classified under another subheading. The core function of vehicle-mounted dental instruments is dental diagnosis and treatment, which conforms to the description of heading 9018, and they are not specifically named in other subheadings 901841 to 901849, so they are classified under 901849. They cannot be classified under Chapter 87 as vehicle parts because their main function is not transportation; nor can they be classified under Chapter 85 as ordinary electric tools because they are specialized medical equipment.

🎯 Classification Logic
The core basis for classification is the function, use and working principle of the goods. The main function of vehicle-mounted dental instruments is dental diagnosis and treatment, which conforms to the description of heading 9018. Their vehicle-mounted attribute is only a use scenario and does not change their essential nature as dental equipment. According to General Rules 1 and 6 for the interpretation of the Harmonized System, they should be classified under 901849. If the equipment is a dental chair integrated with a treatment unit, it may be classified under 901841. 901841 Dental chairs: 901841 specifically refers to dental chairs and their accessories, while 901849 covers other dental instruments. If a vehicle-mounted dental treatment unit includes dental chair functions, classification should be determined based on the main function. 901849 Other dental instruments: This code is the current code and covers dental instruments not otherwise named. 870590 Special purpose vehicles: 870590 covers special purpose vehicles equipped with equipment. If the dental equipment and the vehicle form an integral whole and the vehicle is the essential character, classification is under Chapter 87. However, vehicle-mounted dental equipment is usually detachable, so it is classified under 9018. 854370 Other electrical equipment: 854370 covers electrical equipment with independent functions, but dental instruments, because they are dedicated to medical use, are preferentially classified under 9018. 940290 Medical furniture: 940290 covers medical furniture, such as dental chairs that may be classified here if they do not have treatment functions. However, vehicle-mounted dental treatment machines usually have treatment functions, so they are classified under 9018. Is the product dedicated to dental diagnosis and treatment? Does it form an inseparable whole with the vehicle? Does it include a dental chair and is that its main function? Is the working principle that of electric or pneumatic medical equipment? Can it be classified under a more specific subheading of 9018?

❓ FAQ
Is there a difference in HS codes between vehicle-mounted dental instruments and ordinary dental instruments? There is no difference. HS classification depends on the function and use of the goods, not the use scenario. The core function of vehicle-mounted dental instruments is still dental diagnosis and treatment, so they are classified under 901849. However, the "vehicle-mounted" feature must be noted at declaration so that customs can confirm. If vehicle-mounted dental equipment is imported together with a vehicle, how should it be classified? If the equipment and the vehicle form an integral whole and the vehicle is the essential character, it may be classified under Chapter 87. However, vehicle-mounted dental equipment is usually detachable for independent use, in which case they should be classified separately: the vehicle under Chapter 87 and the equipment under 901849. It is recommended to consult customs based on the actual state. Under which code should a dental handpiece imported separately be classified? If a dental handpiece is imported separately, it is still classified under 901849 because it is a dedicated accessory of dental instruments. However, if imported together with a treatment unit, it should be declared together under 901849. How can I check the import tariff rate for 901849? Tariff rates are adjusted according to national policies. It is recommended to check the latest rates through the official website of the General Administration of Customs or the China International Trade Single Window. Usually, information such as HS code and country of origin is required. How should the "working principle" element be filled in at declaration? It should briefly describe how the equipment works, such as "electrically driven, performing tooth preparation through an air turbine handpiece". Avoid writing only "electric" or "pneumatic"; the medical use should be reflected. What regulatory documents are required for vehicle-mounted dental instruments? Usually a medical device registration certificate or filing certificate is required because they are medical equipment. Specific regulatory conditions can be checked in the Customs Import and Export Tariff or by consulting local customs. If vehicle-mounted dental equipment has X-ray function, does the classification change? If the X-ray function is the main function, it may be classified under 9022 (X-ray equipment). However, if it is only an auxiliary function, it is still classified under 901849. Classification should be determined based on the main function. For cross-border e-commerce sales of vehicle-mounted dental instruments, is the HS code the same? Yes. HS codes are a globally common commodity classification, and cross-border e-commerce also needs to use 901849. However, attention should be paid to regulatory differences between personal use and commercial import.
