Chapter 90 covers optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, precision instruments and apparatus, and parts and accessories thereof. This chapter is one of the most technologically advanced chapters in the HS classification, covering a wide range of products from spectacles and microscopes to medical devices and measuring instruments. Its core characteristic is that these goods are generally used for precision measurement, testing, analysis, or medical purposes, rather than ordinary mechanical or electronic consumer goods. Heading 9026 covers instruments and apparatus for measuring or checking the flow, level, pressure or other variables of liquids or gases, such as flow meters, level gauges, pressure gauges, etc. These instruments are typically used in industrial process control, automotive, aerospace and other fields. This heading also includes parts and accessories of the above instruments, but note that these parts must be solely or principally for use with instruments under 9026. Code 902690 is a 6-digit subheading. The first 2 digits '90' represent Chapter 90 (optical, measuring, medical, etc. instruments). Digits 3-4 '26' represent heading 9026 (instruments for measuring the flow, level, pressure or other variables of liquids or gases). Digits 5-6 '90' represent subheading 9026.90, i.e., parts and accessories solely or principally for use with instruments under heading 9026. Therefore, 902690 specifically refers to parts of vehicle-mounted measuring instruments (such as automotive oil pressure gauges, water temperature gauges, fuel level gauges, etc.), rather than complete instruments. This commodity is a part of vehicle-mounted measuring instruments, not a complete instrument. According to General Rules of Interpretation 1 and 6, if a part is solely or principally for use with instruments under 9026, it should be classified under 9026.90. If the part is a general-purpose part (such as screws, springs), it may be classified under other headings (such as articles of iron or steel). If the part is for use with instruments under other headings (such as navigation instruments under 9025), it should be classified under the parts subheading of the corresponding heading. Therefore, 902690 is the correct classification specifically for parts of 9026 instruments.

Product Name: The specific name of the declared commodity, which should accurately reflect the function or use of the part, such as 'automotive fuel level sensor', 'oil pressure gauge parts', etc. Use: State which measuring instrument the part is used for and the final application scenario, such as 'sensor for automotive fuel level measuring instrument'. Material: The main material of the declared part, such as metal, plastic, electronic components, etc., which helps determine classification. Brand: Fill in the manufacturer or brand name; if no brand, write 'No Brand'. Model: Fill in the specific model or part number of the part for identification. Working Principle: Briefly describe the working principle of the part in the measuring instrument, such as 'measures liquid level through resistance change'. Whether Solely for 9026 Instruments: Clearly declare whether the part is solely or principally for use with measuring instruments under 9026. Customs declaration example: Product Name: Automotive Fuel Level Sensor Use: For automotive fuel level measuring instrument, measures fuel level in the tank Material: Stainless steel housing, electronic components Brand: Bosch Model: F00H600123 Working Principle: Through a float driving a sliding resistor, changes resistance value to output level signal Whether Solely for 9026 Instruments: Yes HS Code: 902690 Mistakenly classifying general-purpose parts (such as standard screws) under 902690; they should be classified under headings for articles of iron or steel. Mistakenly classifying parts for other measuring instruments (such as 9025) under 902690; they should be classified under the corresponding heading. Failing to provide sufficient information to prove the part is solely for 9026 instruments, leading to classification disputes.

The core basis for classification is: 1) whether the part is solely or principally for use with instruments under heading 9026; 2) if it is a general-purpose part, classify by material; 3) if it is for use with instruments under other headings, classify under the corresponding heading. According to the Explanatory Notes to the Harmonized System, parts of 9026 include parts specifically for flow meters, level gauges, pressure gauges, etc., such as sensors, indicators, housings, etc. However, note that if the part itself constitutes a complete instrument, it should be classified under the complete instrument heading. 902620 Instruments for measuring pressure: 902620 is a complete pressure measuring instrument, while 902690 is its parts. If a complete pressure gauge is imported, it should be classified under 902620; if it is only a sensor or case for a pressure gauge, it should be classified under 902690. 902580 Other measuring instruments: 902580 covers other measuring instruments (such as densimeters, thermometers, etc.), and their parts are classified under 902590. If the part is for 9026 instruments, it should be classified under 902690 and must not be confused. 870899 Motor vehicle parts: 870899 is for general motor vehicle parts, but if the part is solely for vehicle-mounted measuring instruments (such as oil pressure gauge parts), it should be classified under 902690 first, as its function is more specific. 903290 Parts of automatic regulating instruments: 903290 is for parts of automatic regulating or controlling instruments. If the part is used for measurement and feedback control, it may be classified under 903290, but pure measuring instrument parts are still classified under 902690. Is the part solely or principally for use with instruments under 9026? Does the part constitute a complete instrument? Is the part a general-purpose part (such as screws, springs)? Is the part for use with instruments under other headings (such as 9025)? Has sufficient information been provided to support classification?

How to determine whether a part should be classified under 902690? First confirm whether the part is solely or principally for use with measuring instruments under 9026 (such as flow meters, level gauges, pressure gauges). If solely for such use, classify under 902690; if it is a general-purpose part, classify by material; if it is for use with instruments under other headings, classify under the parts subheading of the corresponding heading. How to distinguish vehicle-mounted measuring instrument parts from motor vehicle parts (8708)? Vehicle-mounted measuring instrument parts, if solely for measuring instruments (such as fuel level sensors), should be classified under 902690; while general motor vehicle parts (such as bumpers, brake pads) are classified under 8708. The key is whether the part is solely for measuring instruments, and the measuring instrument itself is classified under 9026. Which code should a complete automotive instrument panel be classified under when imported? A complete automotive instrument panel that integrates multiple measuring instruments (such as speedometer, oil pressure gauge, water temperature gauge) is generally classified under the complete instrument heading of 9026 (such as 902620 or 902680), rather than the parts subheading 902690. However, if the instrument panel contains only indicators without measuring functions, it may be classified under other headings. If a part under 902690 has an electronic control unit, will it affect classification? If the electronic control unit is part of the measuring instrument and is solely for 9026 instruments, it is still classified under 902690. However, if the control unit has automatic regulating functions, it may be classified under 9032. Judgment should be based on the primary function. How to check the import tariff rate for 902690? You can check the latest import tariff rate, VAT rate and regulatory conditions by entering HS code 902690 on the official website of the General Administration of Customs of China, the International Trade Single Window, or professional tariff query tools. Note that rates may vary depending on trade agreements, country of origin, and other factors. What certifications are required to export vehicle-mounted measuring instrument parts to the EU? Exporting to the EU generally requires CE certification, depending on the type of part. If the part is for automotive use, E-mark certification may also be required. It is recommended to consult professional certification agencies to ensure compliance with EU regulations. What is the difference between 902690 and 902590? 902690 is for parts of 9026 instruments, and 902590 is for parts of 9025 instruments (such as navigation, meteorological instruments). The difference lies in the different complete instrument headings they belong to, and judgment should be based on the use of the part. If a part can be used for both 9026 instruments and other instruments, how should it be classified? According to General Rule of Interpretation 3 (b), if a part can be classified under multiple headings, it should be classified according to its principal use. If the principal use cannot be determined, the last-in-numerical-order rule applies. It is recommended to provide sufficient evidence to prove the principal use.
