Chapter 90 covers optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, precision instruments and apparatus; parts and accessories thereof. This chapter is divided into multiple headings, including medical and surgical instruments, ray apparatus, measuring instruments, etc. Vehicle-mounted breathing equipment, as a medical or surgical breathing apparatus, falls within the scope of medical equipment in this chapter and is specifically classified under heading 9020. Heading 9020 covers other breathing appliances and gas masks, excluding protective masks having neither mechanical parts nor replaceable filters. This heading includes medical ventilators, anesthesia machines, vehicle-mounted breathing equipment, etc. Vehicle-mounted breathing equipment typically refers to medical equipment installed on vehicles for providing respiratory support or oxygen supply, and falls within the scope of this heading. Code 902000 is a six-digit subheading. The first 2 digits "90" represent Chapter 90, i.e., optical, medical and other instruments and apparatus; digits 3-4 "20" represent heading 9020, i.e., other breathing appliances and gas masks; digits 5-6 "00" is the subheading, indicating goods not further subdivided under this heading. Therefore, 902000 as a whole represents goods not otherwise specified under "other breathing appliances and gas masks," and vehicle-mounted breathing equipment is classified under this code. Vehicle-mounted breathing equipment is a breathing appliance with medical or emergency use, and typically has mechanical parts or replaceable filters, thus classified under heading 9020. It differs from vehicle-mounted equipment under Chapter 87 (such as vehicle parts), and also differs from mechanical breathing devices under Chapter 84 (if their function is more consistent with medical use). According to the General Rules for Interpretation, this product should be classified under 902000.

Product Name: The Chinese and foreign language names of the declared goods, which should accurately reflect the product attributes, such as "vehicle-mounted breathing equipment." Purpose: Explain the specific purpose of the equipment, such as medical emergency, vehicle-mounted oxygen supply, respiratory support, etc. Brand: The brand of the declared goods (Chinese and English); if no brand, indicate "no brand." Model: The model or specification of the declared goods for customs identification. Working Principle: Briefly describe the working principle of the equipment, such as electric drive, oxygen supply, filtration method, etc. Whether it has mechanical parts or replaceable filters: Clearly state whether the equipment contains mechanical parts or replaceable filters, which is key to classification under 9020. Brand Type: Select "foreign brand (OEM production)," "foreign brand (other)," "domestic brand," or "no brand." Export Preference Status: If export tax rebate or preferential trade agreements are involved, the preference status must be declared. Product Name: Vehicle-mounted breathing equipment; Purpose: Used in ambulances, emergency vehicles, etc., to provide respiratory support for patients; Brand: ABC; Model: XYZ-100; Working Principle: Electric drive, oxygen supply through oxygen cylinder, with replaceable filters; Whether it has mechanical parts or replaceable filters: Yes; Brand Type: Foreign brand (other); Export Preference Status: No preference. Mistakenly classifying vehicle-mounted breathing equipment under 8708 (motor vehicle parts), ignoring its medical breathing function. Failing to declare "whether it has mechanical parts or replaceable filters," leading to classification disputes. Misinterpreting "vehicle-mounted" as vehicle-specific parts, when it should actually be classified as a breathing appliance.

The core criteria for classification are: whether the product is a breathing appliance, and whether it has mechanical parts or replaceable filters. Vehicle-mounted breathing equipment typically has mechanical parts (such as pumps, valves) or replaceable filters for medical respiratory support, thus meeting the description of heading 9020. At the same time, Chapter 84 (mechanical breathing devices if purely mechanical and non-medical) and Chapter 87 (vehicle parts) must be excluded. According to General Rules of Interpretation 1 and 6, it is classified under 902000. 901920 Ozone therapy equipment, oxygen therapy equipment, etc.: 901920 covers ozone and oxygen therapy equipment. If vehicle-mounted breathing equipment only provides oxygen therapy without mechanical parts, it might be classified under this code, but vehicle-mounted breathing equipment typically has mechanical parts, so it is classified under 9020. 902110 Orthopedic or fracture appliances: 902110 is for orthopedic or fracture use, completely different in function from breathing equipment, and should not be confused. 870899 Other motor vehicle parts: 870899 is for motor vehicle parts, but the main function of vehicle-mounted breathing equipment is respiratory support, not essential for vehicle operation, so it is not classified under Chapter 87. 841480 Other air pumps or gas compressors: 841480 is for general air pumps. If the breathing equipment is merely an air pump without medical use, it might be classified under this code, but vehicle-mounted breathing equipment is typically for medical use. Is the product used for respiratory support or medical emergency? Does it have mechanical parts or replaceable filters? Is it installed on a vehicle but independent of vehicle operation? Are Chapters 84 and 87 excluded? Is it confirmed that there is no other more specific subheading?

Why is vehicle-mounted breathing equipment classified under 902000 instead of 8708? 8708 is for motor vehicle parts, while the main function of vehicle-mounted breathing equipment is to provide respiratory support, belonging to medical equipment. Even if installed on a vehicle, its core function is still a breathing appliance, so it is classified under 9020. How to determine whether vehicle-mounted breathing equipment has mechanical parts or replaceable filters? Check whether the equipment contains mechanical components such as electric pumps, valves, fans, or whether the filter cartridge is replaceable. If yes, it meets the description of 9020; if it is only a mask without mechanical parts, it may be classified under other codes. How should the "Purpose" field be filled in during declaration? It should be specific, such as "used in ambulances to provide respiratory support for patients," avoiding simply writing "medical use." What certifications are required for exporting vehicle-mounted breathing equipment? Medical device registration certificates, export quality licenses, etc., are typically required, depending on the destination country's requirements. It is recommended to consult professional agencies. If vehicle-mounted breathing equipment is a combination of an oxygen cylinder and a mask, where should it be classified? If the oxygen cylinder and mask are packaged separately, they may be classified separately; if combined as a set for breathing, they are typically classified as a breathing appliance under 9020. How to check the tariff rate for 902000? You can check China Customs' "Import and Export Tariff" or the General Administration of Customs website. Tariff rates may change, so it is recommended to refer to the latest announcement. Is there a difference in classification between vehicle-mounted breathing equipment and home ventilators? If the functions are the same, both are classified under 9020; however, home ventilators may be more commonly classified under 9019, and judgment should be based on specific functions. How to choose the brand type during customs declaration? Choose based on brand ownership: foreign brand (OEM production), foreign brand (other), domestic brand, or no brand.
