Chapter 90 is the HS classification system for optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, precision instruments and apparatus; parts and accessories thereof. This chapter covers an extremely broad scope, from spectacles, microscopes, and lasers to medical diagnostic equipment and dental instruments. The core characteristics are that these goods are usually precision, technical, and specialized, used for purposes such as measurement, detection, treatment, or correction. This chapter is clearly distinguished from Chapter 84 machinery and Chapter 85 electrical equipment, but many modern medical devices may involve overlap across multiple chapters. Heading 9021 covers appliances and implants for orthopedic surgery, orthopedics, dentistry, etc., including artificial body parts, hearing aids, cardiac pacemakers, etc. Specifically, it includes artificial joints, bone plates, bone screws, dental implants, artificial teeth, dental fixtures, etc. Goods under this heading are usually used to replace or support the functions of human organs and have the characteristics of medical implantation or long-term use. They are clearly distinguished from the X-ray equipment of 9022 and the physicochemical analysis instruments of 9027. The first 2 digits 90: indicates Chapter 90, covering optical, medical, and other precision instruments and equipment. Digits 3-4, 21: indicate heading 9021, namely orthopedic, dental, and other implants and appliances. Digits 5-6, 29: indicate subheading 902129, specifically other dental implants and accessories. In the HS classification, under 9021 there are also 902110 (orthopedic or fracture appliances), 902121 (artificial teeth), 902129 (other dental implants), 902131 (artificial joints), etc. 902129 specifically refers to dental implants other than artificial teeth, such as implants, abutments, dental screws, etc. If a vehicle-mounted dental implant is imported separately as a dental implant, it should be classified under 902129, because it is essentially a dental implant used to replace missing teeth. However, if it is combined with a vehicle and becomes a vehicle-specific part, it may be classified under Chapter 87 vehicle parts. When classifying, it is necessary to determine the main function of the product: if the implant is sold independently and used for dental treatment, it is classified under 902129; if it has been integrated into a vehicle as a functional vehicle part, it may be classified under 8708, etc. Usually, dental implants imported separately are classified under 902129.

📝 Declaration Elements
Product name: The Chinese and foreign-language name of the declared goods, which should accurately reflect the product attributes, such as 'dental implant' or 'vehicle-mounted dental implant'. Material: The main material of the declared implant, such as pure titanium, titanium alloy, ceramics, etc. The material affects classification and regulatory conditions. Use: Clearly state the use of the goods, such as 'for dental implant restoration' or 'for vehicle-mounted dental treatment equipment'. Brand: Declare the brand of the goods (Chinese or foreign language). If there is no brand, state 'no brand'. Model: Declare the model of the goods to facilitate customs identification of the specific product. Sterile or not: Declare whether it has undergone sterile processing, which affects regulatory conditions (such as medical device registration). With accessories or not: Declare whether accessories are included (such as screws, abutments, etc.). Accessories must be declared separately. Example of customs declaration form: Product name: dental implant (vehicle-mounted dental implant); Brand: Straumann; Model: BLT 4.1×10mm; Material: titanium alloy; Use: for dental implant restoration; Sterile or not: yes; With accessories or not: with central screw. Remarks: This product is a separately imported dental implant used for dental treatment, not a vehicle-specific part. Incorrectly classifying the goods under a vehicle parts code (such as 8708), ignoring their nature as dental implants. Failure to declare sterility status, resulting in inability to enjoy relevant free trade agreement preferences or violation of regulatory requirements. False declaration of material, such as declaring titanium alloy as pure titanium, affecting classification and the application of anti-dumping duties.

🎯 Classification Logic
Core basis for classification: the function, use, and material of the goods. 902129 specifically refers to other dental implants, including implants, abutments, dental screws, etc. If the goods are artificial teeth, they are classified under 902121; if they are orthopedic or fracture appliances, they are classified under 902110. If a vehicle-mounted dental implant is imported separately as a dental implant, it should be classified under 902129; if it is combined with a vehicle and becomes a vehicle-specific part, it may be classified under Chapter 87. According to the Explanatory Notes to the Harmonized System, dental implants refer to devices surgically implanted into the jawbone to support artificial teeth. 902121 Artificial teeth: Artificial teeth are prostheses that replace missing teeth and are directly exposed in the oral cavity, while dental implants are supporting structures implanted into the jawbone and require surgery. 902110 Orthopedic or fracture appliances: Orthopedic appliances are used for bone correction or fracture fixation, such as bone plates and bone screws, while dental implants are specifically used for dental implantation. 902131 Artificial joints: Artificial joints are used for hip, knee, and other joint replacement, while dental implants are used in the alveolar bone, with different functional sites. 870899 Other vehicle parts: Vehicle parts are used for motor vehicles, while vehicle-mounted dental implants, if they are independent dental products, should not be classified as vehicle parts. Is the product used for dental implant restoration? Does the product need to be surgically implanted into the jawbone? Is the product sold independently of the vehicle? Is the product made of medical materials such as titanium or ceramics? Does the product have a medical device registration certificate?
