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 has a broad scope, ranging from simple lenses to complex electron microscopes, but excludes instruments for certain specific uses (such as medical furniture of Chapter 94). The core characteristic is that these instruments and apparatus are generally used for measuring, detecting, observing or analyzing, and are often characterized by precision or specialization. Heading 9011 covers optical microscopes, including stereoscopic microscopes, compound optical microscopes, and microscopes for photomicrography, cinephotomicrography or microprojection. However, it excludes non-optical microscopes (such as electron microscopes and proton microscopes, classified under 9027) and microscopes for semiconductor manufacturing (classified under 8486). Microscopes under this heading are mainly used for observing minute objects, magnifying images through an optical system. The first 2 digits 90 represent Chapter 90 (optical, photographic, medical and other equipment). Digits 3-4, 11, represent heading 9011 (optical microscopes). Digits 5-6, 80, are the subheading, representing other optical microscopes (not elsewhere specified). Under 9011, subheading 9011.10 is stereoscopic microscopes, 9011.20 is other microscopes (for photomicrography, cinephotomicrography or microprojection), 9011.80 is other optical microscopes, and 9011.90 is parts and accessories. Therefore, 901180 specifically refers to other optical microscopes not elsewhere specified, such as metallurgical microscopes, polarizing microscopes, etc. Although a vehicle-mounted optical microscope is installed on a vehicle, its core function is optical microscopic observation, which conforms to the definition of "optical microscopes" under 9011. It does not belong to 9012 (non-optical microscopes), nor to 8708 (parts of motor vehicles), because it is not a component necessary for vehicle operation but an independent optical instrument. Therefore, it is classified under 901180, namely other optical microscopes.

🎯 Classification Logic
The core basis for classification is the notes to Chapter 90 of the Import and Export Tariff and the text of heading 9011. 9011 includes optical microscopes, whether or not equipped with photographic or camera devices. Although a vehicle-mounted optical microscope is installed on a vehicle, its main function is microscopic observation, which conforms to the description of 9011. According to General Rules of Interpretation 1 and 6, it should be classified under 901180. 901120 Microscopes for photomicrography, cinephotomicrography or microprojection: 901120 specifically refers to microscopes for photomicrography, photography or projection, while 901180 is other optical microscopes. If the vehicle-mounted microscope has a photographic function, it should be classified under 901120. 901210 Non-optical microscopes and diffraction apparatus: 901210 includes microscopes based on non-optical principles such as electron microscopes and proton microscopes, while 901180 is based on optical principles. 901380 Other optical instruments and appliances: 901380 covers optical instruments not elsewhere specified, such as magnifying glasses and optical door viewers, but microscopes are explicitly classified under 9011. 870829 Parts and accessories of motor vehicles: 870829 is for parts of motor vehicles, but a vehicle-mounted microscope is an independent optical instrument and does not constitute a necessary component of the vehicle, so it is not classified under this. Is it based on optical principles? Is it used for microscopic observation? Does it have a photographic or camera function? Is it specially designed for vehicles? Does it belong to other subheadings of 9011 not elsewhere specified?

❓ FAQ
Is there any difference in classification between a vehicle-mounted optical microscope and an ordinary optical microscope? There is no difference. HS classification is based on the function and principle of the commodity, not the installation location. A vehicle-mounted optical microscope is still classified as an optical microscope under 901180, unless it has a photographic function, in which case it is classified under 901120. If the vehicle-mounted microscope has a USB interface and can be connected to a computer, does this affect classification? It does not affect classification unless the interface is used to transmit images and has a photographic function. If it is only used for power supply or data transmission, it is still classified as an optical microscope. However, if it has digital imaging capability, it may be regarded as a photomicrographic microscope and classified under 901120. How can one determine whether a vehicle-mounted microscope belongs to 901180? Confirm that it uses an optical lens system for magnified observation of minute objects, and is not equipped with photographic, cinematographic or projection devices, and is not classified under other subheadings; then it can be classified under 901180. Is it necessary to provide the magnification of the microscope when declaring? Yes, magnification is an important declaration element and helps customs confirm the product attributes and classification. It is recommended to provide a specific range, such as 40X-1000X. How are parts of a vehicle-mounted optical microscope classified? Specialized parts or accessories should be classified under 901190, but general parts (such as screws) are classified according to material. If the microscope is a sensor installed on a vehicle for autonomous driving, is the classification different? If its function is environmental perception rather than microscopic observation, it may be classified under other headings, such as 8512 or 9027. But if it is still for microscopic observation, it is classified under 901180. What is the export tax rebate rate for 901180? The export tax rebate rate may be adjusted with policy changes. Please consult the latest export tax rebate rate database or customs. Generally, the rebate rate for optical instruments is relatively high, but the actual rate shall prevail.
