Chapter 90 is the chapter in the HS classification system covering optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, precision instruments and apparatus; parts and accessories thereof. This chapter covers an extremely wide range, from spectacles and microscopes to medical equipment and industrial measuring instruments. The core characteristic is that these goods generally have precision, measuring, or checking functions, rather than being simple mechanical or electrical products. Heading 9024 covers mechanical property testing equipment for various materials (including metals, wood, plastics, rubber, textiles, etc.), as well as instruments used for testing physical properties such as hardness, strength, durability, and elasticity of materials. These devices are typically used in industrial quality control, R&D laboratories, and material inspection fields. The first 2 digits 90 represent Chapter 90 (optical, measuring, checking, medical and other precision instruments and equipment). Digits 3-4, 24, represent heading 9024, i.e., mechanical property testing equipment for various materials. Digits 5-6, 80, are the subheading, representing other material testing equipment not elsewhere specified or included. The complete code 902480 refers to material mechanical property testing equipment not specifically named, including mobile testing devices such as vehicle-mounted testing equipment. Vehicle-mounted testing equipment is used for dynamic performance testing of materials or components during vehicle operation, falling within the scope of material mechanical property testing equipment. Because of its mobile testing characteristics and because it is not specifically named under other subheadings of 9024 (such as 902410 for metal testing, 902420 for plastic testing, etc.), it is classified under 902480 as other.

Product Name: The Chinese and English names of the declared goods, which should accurately reflect the equipment's function, such as vehicle-mounted testing equipment. Use: Explain the specific application scenario of the equipment, such as being used to test material fatigue strength during vehicle operation. Working Principle: Briefly describe how the equipment achieves its testing function, such as collecting and analyzing data through sensors. Brand: Fill in the equipment brand or manufacturer name; if there is no brand, indicate "no brand." Model: Fill in the specific model of the equipment so that customs can identify it. Test Object: Clearly specify the material or component being tested, such as metal, plastic, rubber, etc. Vehicle-Mounted or Not: Confirm whether the equipment is designed for vehicle-mounted use, which affects classification. Product Name: Vehicle-mounted testing equipment; Use: Used for real-time testing of the fatigue strength of metal materials during vehicle operation; Working Principle: Data is collected through acceleration sensors and strain gauges and analyzed by an onboard computer; Brand: ABC; Model: XYZ-100; Test Object: Metal materials; Vehicle-Mounted or Not: Yes. Failure to indicate the "vehicle-mounted" characteristic may lead to incorrect classification under other testing equipment. Unclear description of the test object may cause confusion with 902410 or 902420. The working principle description is too simple to prove that it belongs to mechanical property testing.

The core basis for classification is whether the equipment's function is material mechanical property testing and whether it is designed for vehicle-mounted use. According to HS notes, 9024 covers material mechanical property testing equipment, including mobile types. Vehicle-mounted testing equipment, because it is used on vehicles and tests material properties, falls under subheading 902480 "other." Note that if the equipment's main function is testing the performance of the vehicle itself, it should be classified under vehicle parts headings such as 8708. 902410 Metal material testing equipment: 902410 is specifically for metal material testing, while 902480 covers other materials or testing equipment not elsewhere specified. If vehicle-mounted testing equipment only tests metals, it may be classified under 902410. 902420 Plastic and rubber material testing equipment: 902420 is specifically for plastic and rubber testing. If the test object of the vehicle-mounted equipment is plastic or rubber, it should be classified under this code. 903180 Other measuring or checking instruments: 903180 covers measuring instruments for non-mechanical property testing, such as temperature and pressure. If vehicle-mounted testing equipment tests mechanical properties, it should be classified under 902480. 870899 Other parts for vehicles: 870899 is for vehicle parts. If the equipment is a fixed component of the vehicle and its main function is vehicle operation rather than independently testing materials, it is classified under this code. Is the equipment used to test the mechanical properties of materials? Is the equipment designed for vehicle-mounted use? Is the test object metal, plastic, rubber, or other materials? Is the equipment independent of the vehicle's own functions? Is it not specifically named under other subheadings of 9024?

Which HS code should vehicle-mounted testing equipment be classified under? It is usually classified under 902480, but it must be confirmed that the equipment's function is material mechanical property testing and that it is used vehicle-mounted. If the test object is metal, it may be classified under 902410; if it is plastic or rubber, under 902420. It is recommended to provide detailed technical information for accurate classification. How can one determine whether vehicle-mounted testing equipment is classified under 902480 or 8708? The key is the main function of the equipment. If the equipment is an independent testing instrument used to test material properties, even if installed on a vehicle, it should be classified under 902480. If the equipment is an inherent vehicle component used for vehicle operation monitoring or control, it is classified under 8708. What elements need attention during declaration? It is necessary to accurately declare the product name, use, working principle, brand, model, test object, whether vehicle-mounted, etc. In particular, the characteristics of "vehicle-mounted" and "material mechanical property testing" should be highlighted to avoid vague descriptions. What is the import tariff rate for 902480? Tariff rates vary by country, trade agreement, and time period. It is recommended to consult the latest China Customs tariff schedule or use official tariff query tools. We cannot provide specific figures. What certifications are required for vehicle-mounted testing equipment? Certification is usually required according to the requirements of the destination country, such as CCC in China and CE in the EU. The specifics depend on the equipment type and use. It is recommended to consult professional certification agencies. If the equipment can test both metal and plastic, how should it be classified? If the equipment can test multiple materials and is not specifically designed for one material, it is usually classified under 902480 "other." If it mainly tests metal, it may be classified under 902410. The judgment should be based on the main function. How can classification errors be avoided during customs declaration? Provide detailed product manuals, technical parameters, working principle diagrams, etc., and apply for advance classification if necessary. Ensure that the declaration elements are complete and accurate, especially the test object and vehicle-mounted characteristics. What is the difference between 902480 and 903180? 902480 is specifically for material mechanical property testing, such as hardness, strength, fatigue, etc.; 903180 is for other measurement or checking, such as temperature, pressure, flow, etc. The core difference lies in the type of test parameters.
