Chapter 90 is the core chapter in the HS classification system for optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, and precision instruments and apparatus, covering a range from simple spectacle lenses to complex electronic measuring instruments. Goods in this chapter generally have the characteristics of being technology-intensive, relatively high in value, and used for professional measurement or medical purposes. As an electronic measuring instrument, a vehicle-mounted multimeter is classified in this chapter because of its function of measuring electrical parameters. Heading 9030 specifically covers oscilloscopes, spectrum analyzers and other instruments and apparatus for measuring or checking electrical quantities, but excludes supply meters of heading 9028 (such as electricity meters) and measuring or checking instruments of heading 9031. The core function of goods under this heading is to measure electrical parameters such as voltage, current and resistance. A vehicle-mounted multimeter is precisely a portable instrument used to measure electrical parameters of an automobile electrical system, and is therefore classified under this heading. The first 2 digits "90" represent Chapter 90, namely optical, measuring, checking, medical and other precision instruments and equipment. The 3rd-4th digits "30" represent heading 9030, specifically oscilloscopes, spectrum analyzers and other instruments for measuring or checking electrical quantities. The 5th-6th digits "31" are the subheading, representing multimeters, namely a multifunctional electrical parameter measuring instrument that can measure voltage, current, resistance, etc. Therefore, 903031 fully represents "vehicle-mounted multimeter" and is the specific subdivision of the multimeter subheading under heading 9030. A vehicle-mounted multimeter is essentially a type of multimeter, used to measure parameters such as voltage, current and resistance in automobile circuits, and conforms to the description of heading 9030 as "instruments for measuring or checking electrical quantities." It is not classified under 9028 (supply meters) because its function is not to measure electrical energy consumption; nor is it classified under 9031 (other measuring or checking instruments) because multimeters are already explicitly listed under 9030. Therefore, 903031 is the correct classification.

Product name: The Chinese and foreign-language names of the declared goods, which should accurately reflect the product attributes, such as "vehicle-mounted multimeter" or "automotive digital multimeter." Brand type: Fill in the brand attribute, such as "no brand," "domestic independent brand," "foreign brand (OEM production)," etc. Export preferential treatment status: Fill in according to whether preferential export tariffs are enjoyed, such as "export goods do not enjoy preferential tariffs in the final destination country." Use: Explain the use of the goods, such as "used for inspection and repair of automobile electrical systems." Function: Describe the main functions of the goods, such as "measuring voltage, current, resistance, continuity, etc." Brand: Fill in the brand name of the goods (Chinese or foreign language); if there is no brand, fill in "none." Model: Fill in the product model, such as "DT9205A." Whether it has a recording device: Explain whether the multimeter has a data recording function, such as "with recording device" or "without." Customs declaration example: Product name: Vehicle-mounted multimeter Brand type: Foreign brand (OEM production) Export preferential treatment status: Export goods do not enjoy preferential tariffs in the final destination country Use: Used for inspection and repair of automobile electrical systems Function: Measuring voltage, current, resistance, continuity, diode test Brand: FLUKE Model: 88V Whether it has a recording device: No Mistakenly classifying a vehicle-mounted multimeter under 9031 (other measuring or checking instruments), resulting in incorrect classification. Incomplete declaration elements, such as omitting "brand type" or "export preferential treatment status." The function description is too simple and does not reflect the multifunctional characteristics of the multimeter, which may trigger customs questions.

The core basis for classification is the function and use of the goods. The main function of a vehicle-mounted multimeter is to measure electrical parameters (voltage, current, resistance, etc.), which conforms to the description of heading 9030 as "instruments for measuring or checking electrical quantities." Its "vehicle-mounted" use only indicates the usage scenario and does not change its nature as a multimeter. According to the Explanatory Notes to the Import and Export Tariff, multimeters are explicitly classified under 9030, and subheading 903031 specifically refers to multimeters. Therefore, as long as the goods have the basic functions of a multimeter, they should be classified under 903031. 903020 Oscilloscopes and oscilloscope plug-ins: Oscilloscopes are used to display electrical signal waveforms, while multimeters are used to measure numerical electrical parameters; their functions are different. 903033 Other instruments for measuring or checking electrical quantities: This subheading covers other electrical quantity measuring instruments that are not multimeters, such as voltmeters and ammeters; multimeters are excluded because they are already specifically listed. 903180 Other measuring or checking instruments: This subheading belongs to 9031 and covers non-electrical measuring instruments, such as automotive diagnostic tools, whereas multimeters are for electrical quantity measurement. 902830 Electricity meters: Electricity meters are used to measure electrical energy consumption, while multimeters are used to measure instantaneous electrical parameters; their functions are different. Does the product have the basic functions of a multimeter (measuring voltage, current, resistance, etc.)? Is the product clearly intended for vehicle-mounted use, but its function is still mainly electrical parameter measurement? Has it been incorrectly classified under 9031 (other measuring or checking instruments)? Are the declaration elements complete, especially brand type and export preferential treatment status? Has the multimeter been confused with similar instruments such as oscilloscopes or electricity meters?

Is there any difference in HS code classification between a vehicle-mounted multimeter and an ordinary multimeter? There is no difference. HS code classification is based on the function and principle of the goods, not the usage scenario. Both vehicle-mounted multimeters and ordinary multimeters have the function of measuring electrical parameters such as voltage, current and resistance, so both are classified under 903031. However, when declaring, "vehicle-mounted" should be noted in the "Use" element so that customs can understand the actual usage. How can I check the import tariff rate for 903031? The import tariff rate must be determined according to the country of origin, trade agreements and the latest tariff schedule. Through the official website of the General Administration of Customs of China, the International Trade Single Window, or professional tariff query tools, enter HS code 903031 and the country of origin to obtain the MFN rate, agreement rate, etc. Note that tariff rates change with policy adjustments, and the tariff schedule at the time of declaration should prevail. What certifications are required for exporting vehicle-mounted multimeters? Export certification depends on the requirements of the destination country. Common certifications include EU CE, US FCC, Canada IC, etc. In addition, if wireless functions are included, radio certification may be required. It is recommended to confirm certification requirements with the buyer in advance and ensure the product complies with relevant standards. The HS code itself does not determine certification, but classification affects regulatory conditions. What is the main difference between 903031 and 903033? 903031 specifically refers to multimeters, namely a multifunctional electrical parameter measuring instrument that can usually measure voltage, current, resistance, etc. 903033 covers other instruments for measuring or checking electrical quantities, such as single-function voltmeters, ammeters and ohmmeters. If an instrument has the multifunctional characteristics of a multimeter, it should be classified under 903031; otherwise, it should be classified under 903033. How is "whether it has a recording device" determined when declaring? A recording device refers to a device capable of automatically recording and storing measurement data, such as built-in memory or data logging functions. If a multimeter only has a data hold (Hold) function, it is not considered a recording device. If it can store multiple sets of data and export them, it is regarded as having a recording device. It must be truthfully filled in during declaration to avoid affecting classification or regulatory conditions. What are the regulatory conditions for classifying a vehicle-mounted multimeter under 903031? Regulatory conditions vary by country/region. In China, 903031 generally has no special regulatory conditions, but it must comply with the regulations on the import administration of mechanical and electrical products. For export, there are usually no special regulatory requirements, but if brand infringement or technology export controls are involved, additional attention is required. The latest customs announcements shall prevail. If a multimeter has an automotive diagnostic function, which code should it be classified under? If the main function of the multimeter is still electrical parameter measurement and it has only a simple diagnostic function (such as continuity testing), it should still be classified under 903031. If the diagnostic function becomes the main function, such as reading OBD-II fault codes, it may be classified under 9031 (other measuring or checking instruments). Classification should be based on the main function. For cross-border e-commerce sales of vehicle-mounted multimeters, how should the HS code be filled in? For cross-border e-commerce export declarations, HS code 903031 must be filled in. At the same time, elements such as product name, brand, model and use must be provided. If declaring through postal or express channels, the declaration may be simplified, but the code must still be accurate. It is recommended to consult a customs broker or use customs advance classification services to ensure compliance.
