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 a very wide range, from spectacles, microscopes, and lasers to medical devices and industrial measuring instruments. Its core characteristic is that these goods are usually precision, functional, and used in professional fields such as measurement, analysis, control, and medical care. The classification of parts under this chapter must follow the principle of "solely or principally for use with the equipment listed under a particular heading of this chapter." Heading 9029 covers revolution counters, production counters, taximeters, odometers, pedometers and the like; speedometers and tachometers (other than those of heading 9028); stroboscopes. These instruments are mainly used to measure or record physical quantities such as speed, rotational speed, production quantity, and mileage. Their common feature is that they have counting or speed-measuring functions, usually with mechanical or electronic display devices. This heading includes automobile odometers, taximeters, tachometers, production counters, etc., but does not include electricity measuring instruments of heading 9028. Code 902990 consists of 6 digits. The first 2 digits "90" represent Chapter 90, namely optical, photographic, measuring, medical and other instruments and apparatus. The 3rd-4th digits "29" represent heading 9029, namely revolution counters, production counters, taximeters, odometers, pedometers and the like; speedometers and tachometers; stroboscopes. The 5th-6th digits "90" represent subheading 9029.90, namely other. This subheading covers parts and accessories not specifically named under heading 9029. Therefore, 902990 fully means "parts and accessories of instruments listed under heading 9029 (such as odometers, tachometers, counters, etc.)." This commodity is a vehicle instrument part, specially or mainly used for odometers, speedometers, tachometers, etc. on automobile instrument panels (heading 9029). According to General Rules of Interpretation 1 and 6, if a part is specially used for goods of a certain heading, it should be classified under the parts subheading of that heading. 902990 is exactly the parts subheading of heading 9029, so it is classified under this code. It is not classified under the parts of heading 9028 (electricity measuring instruments) or 9032 (automatic regulating instruments), because vehicle instruments usually measure non-electrical quantities such as speed and mileage, and do not involve automatic regulating functions.

Product name: The Chinese and foreign language names of the declared commodity should accurately reflect the purpose of the part, such as "automobile odometer sensor," "tachometer pointer," etc. Use: Explain what kind of instrument the part is specially used for, such as "used for automobile odometers," "used for taximeters," etc., and it must correspond to goods of heading 9029. Material: Declare the main material of the part, such as plastic, metal, electronic components, etc., which affects classification and regulatory conditions. Brand: Declare the brand of the part (such as Bosch, Denso, etc.); if there is no brand, indicate "no brand." Model: Declare the model or part number of the part to facilitate customs identification and classification. Whether dedicated: Declare whether the part is specially used for instruments listed under heading 9029 or is a general-purpose part. Only dedicated parts may be classified under this code. Working principle: Briefly explain the function of the part in the instrument, such as "converts rotational speed signal into electrical signal," "displays mileage digits," etc. Product name: automobile odometer sensor; Use: specially used for automobile odometers to collect vehicle speed signals; Material: plastic housing + copper coil; Brand: Bosch; Model: 0261234567; Whether dedicated: dedicated; Working principle: converts wheel rotational speed into electrical pulse signals through the Hall effect and transmits them to the odometer for display. Incorrectly classifying general-purpose parts (such as standard screws and gaskets) under this code; they should actually be classified according to material. Failure to distinguish parts of heading 9029 from those of 9028, and incorrectly classifying parts of electricity measuring instruments under this code. Ignoring the "dedicated use" requirement and classifying parts that can be used for other equipment under this code, leading to classification disputes.

The core criterion for classification is whether the part is specially or mainly used for instruments listed under heading 9029. According to the Explanatory Notes to the Harmonized Commodity Description and Coding System, heading 9029 covers revolution counters, production counters, taximeters, odometers, pedometers and the like; speedometers and tachometers; stroboscopes. If their parts are specially used for these instruments, they should be classified under subheading 9029.90. If the parts are general-purpose parts (such as screws and springs), they should be classified according to material (for example, iron or steel under 7318). If the parts are used for electricity measuring instruments of heading 9028, they should be classified under the parts subheading of 9028. Therefore, a comprehensive judgment must be made based on use, function, and dedicated nature. 9028 Parts of electricity measuring instruments: 9028 covers electricity measuring instruments (such as ammeters and voltmeters), and their parts are classified under 9028.90. 9029 covers non-electrical measuring instruments (such as speed and rotational speed), and their parts are classified under 9029.90. The core difference lies in whether the physical quantity measured is electrical. 9032 Parts of automatic regulating instruments: 9032 covers automatic regulating or controlling instruments, and their parts are classified under 9032.90. If vehicle instrument parts have automatic regulating functions (such as cruise control sensors), they may be classified under 9032 rather than 9029. 8708 Motor vehicle parts: 8708 covers general-purpose motor vehicle parts, but instrument parts specially used for instrument panels should be classified under 9029. If the part is part of an instrument panel assembly but not the instrument itself, it may be classified under 8708. 9027 Parts of analyzing instruments: 9027 covers instruments for analysis, measuring flow, liquid level, etc., and their parts are classified under 9027.90. If vehicle instrument parts are used to measure liquid level or flow, they may be classified under 9027. Is the part specially used for instruments listed under heading 9029? Is the part used to measure non-electrical quantities (speed, rotational speed, mileage)? Does the part have an automatic regulating function? Is the part a general-purpose part (such as a standard part)? Is the part used for electricity measuring instruments?

How can I query the import tariff rate for 902990? It can be queried through the official website of the General Administration of Customs, China International Trade Single Window, or the Customs Tariff of the People's Republic of China. Tariff rates will be adjusted according to national policies, and the latest tariff should prevail. When querying, attention should be paid to factors such as origin and trade agreements, as preferential rates may apply. If vehicle instrument parts are classified under 902990, is 3C certification required? 3C certification is aimed at complete vehicles or specific parts, and instrument parts are usually not in the 3C catalog. However, if the parts involve safety or environmental protection requirements, they may need to comply with other certifications. It is recommended to check the Announcement of the State Administration for Market Regulation on Issuing the Catalog of Compulsory Product Certification. Are car navigation device parts classified under 902990? Car navigation devices are usually classified under 8527 or 8528, and their parts are classified under the corresponding tariff numbers. 902990 only applies to parts of instruments listed under heading 9029 (such as odometers and tachometers). Navigation devices do not belong to 9029, so they are not classified under this code. If general-purpose screws are used in automobile instruments, should they be classified under 902990 or 7318? If general-purpose screws meet the definition of standard parts, they should be classified according to material (for example, iron or steel under 7318). Only parts specially used for instruments and non-replaceable are classified under 902990. If the screws are designed specifically for instruments, they may be classified under this code. How are parts under 902990 and 902890 distinguished? 9028 is for electricity measuring instruments (such as electricity meters), and 9029 is for non-electrical measuring instruments (such as speedometers). If the part is used to measure electricity, it is classified under 902890; if it is used to measure speed, rotational speed, etc., it is classified under 902990. Judgment should be based on the function of the instrument. How should "whether dedicated" be filled in during declaration? If the part is only used for instruments listed under heading 9029, fill in "dedicated"; if it can be used for other equipment, fill in "general-purpose." Evidence (such as technical drawings and contracts) must be provided in support. Incorrect filling may lead to classification disputes. When exporting to the EU, what is the corresponding code for 902990? The first 6 digits of the EU HS code are consistent with those of China, and 902990 corresponds to EU CN code 9029 90 00. However, the EU may further subdivide it, so it is recommended to check the EU TARIC database. When exporting, attention should be paid to additional EU requirements, such as REACH regulations. When instrument parts are imported, what are the key points of customs inspection? Customs focuses on inspecting whether the parts are specially used for 9029 instruments, whether the declaration elements are complete, whether the brand and model are truthful, and whether infringement is involved. It is recommended to retain technical materials, contracts, invoices, etc. for verification.
