Chapter 90 covers optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus, precision instruments and apparatus; parts and accessories thereof. The core characteristics of this chapter are 'precision' and 'functionality'; goods are typically used in professional fields such as measurement, observation, transmission, analysis, or medical treatment. Optical elements (such as lenses, prisms) and their assemblies are important components of this chapter, but attention must be paid to distinguishing them from Chapter 85 (electrical equipment) and Chapter 87 (vehicles). Optical lenses classified under this chapter must have an independent optical function, rather than merely serving as dedicated parts of a particular device. Heading 9002 includes: lenses, prisms, mirrors and other optical elements, of any material, mounted, being parts of or fittings for instruments or apparatus, other than such elements of glass not optically worked. This heading emphasizes 'mounted' and 'being parts of or fittings for instruments or apparatus,' meaning the optical elements must be assembled and possess a specific optical function, for use in a certain instrument or device. Vehicle-mounted optical lenses are typically assembled from multiple lenses, a barrel, an aperture, etc., and are used in vehicle camera, sensing, LiDAR and other systems, conforming to the definition of this heading. The first 2 digits '90' represent Chapter 90 (optical, photographic, measuring, medical and other instruments and apparatus). The 3rd-4th digits '02' represent heading 9002 (mounted optical elements). The 5th-6th digits '19' are a subheading meaning 'other' mounted optical elements, not named in the preceding subheadings (such as 9002.11 for cameras, projectors, etc.; 9002.19 for other). Therefore, 900219 specifically refers to 'other mounted optical elements.' Vehicle-mounted optical lenses, because they are not for the camera, projector, or similar uses of 9002.11, are classified under this subheading. Vehicle-mounted optical lenses are classified under 900219 because they are mounted optical elements and are mainly used in vehicle camera, sensing, LiDAR and other systems, not for cameras, projectors, or cinematographic cameras (which are classified under 900211). At the same time, they are not parts of vehicles under Chapter 87, because their core function is optical imaging or sensing, rather than vehicle mechanical or electrical components. According to General Rules of Interpretation 1 and 6, the goods conform to the description of heading 9002 and subheading 900219.

Product Name: The Chinese and foreign language names of the declared goods, which should accurately reflect the product attributes, such as 'vehicle-mounted optical lens'. Use: Explain the specific application scenario of the lens, such as 'used for vehicle-mounted cameras,' 'used for ADAS systems,' 'used for LiDAR,' etc. Material: The main material of the lens, such as glass, resin, plastic, etc., as well as the material of the barrel (such as metal, plastic). Brand: The manufacturer or brand name; if there is no brand, 'no brand' may be entered. Model: The specification and model of the product, used to distinguish different products. Composition: What parts the lens is composed of, such as the number of lens elements, aperture, filter, etc. Whether Mounted: Clearly state whether the optical elements have been assembled into a lens; mounted ones are classified under 9002, unmounted ones under other headings. Product Name: Vehicle-mounted optical lens; Use: Used for vehicle-mounted front-view camera to realize ADAS environmental perception; Material: glass lenses, plastic barrel; Brand: XX; Model: XX-123; Composition: Assembled from 6 glass lenses, 1 aperture, 1 filter and a barrel; Whether Mounted: Yes. Failure to indicate the 'vehicle-mounted' use, resulting in classification under other optical lens subheadings. Mistakenly reporting unmounted lens elements as mounted lenses, incorrectly classified under 9002. Ignoring the materials of non-optical parts such as the barrel, affecting classification.

Core basis for classification: 1) whether the goods are mounted optical elements; 2) whether they are parts of instruments or apparatus; 3) whether the specific use falls under cameras, projectors, etc. listed in 9002.11. Vehicle-mounted optical lenses are usually mounted and used in vehicle camera or sensing systems, not belonging to 9002.11, so they are classified under 9002.19. If the lens is unmounted, it is classified under 9001 (unmounted optical elements); if it is a dedicated vehicle part without optical function, it may be classified under Chapter 87. 900211 Mounted optical elements for cameras, projectors, cinematographic cameras: Used for cameras, projectors and other consumer electronics, not vehicle-mounted systems. 900190 Other unmounted optical elements: Unmounted, only a single lens or prism, without barrel or other assembly. 870829 Other parts and accessories for vehicles: Used for vehicle mechanical or electrical components, without optical imaging function. 851290 Parts of lighting or signaling devices for vehicles: Used for vehicle lamps and other lighting devices, not imaging lenses. Is the lens mounted? Is it used for vehicle-mounted camera or sensing? Does it belong to camera or projector use? Does it have an independent optical function? Is it a dedicated vehicle part?

Which HS code should vehicle-mounted optical lenses be classified under? Usually under 900219, i.e., other mounted optical elements. However, it must be confirmed that the lens is mounted and used in vehicle camera or sensing systems, rather than cameras or projectors. If unmounted, it is classified under 900190. How to distinguish 900219 from 900211? 900211 specifically refers to mounted optical elements for cameras, projectors, and cinematographic cameras; 900219 is mounted optical elements for other uses. Vehicle-mounted lenses are used in vehicle systems, not belonging to 900211, so they are classified under 900219. If a vehicle-mounted lens is unmounted, which code is it classified under? Unmounted optical elements are classified under 900190, i.e., other unmounted optical elements. Mounted means lenses, barrel, etc. are combined into a complete lens. What elements need attention during declaration? It is necessary to declare the product name, use, material, brand, model, composition, whether mounted, etc. The use should clearly state 'vehicle-mounted camera' or 'ADAS,' avoiding a vague 'for vehicles.' Are vehicle-mounted LiDAR lenses classified under 900219? Yes, LiDAR lenses are usually mounted optical elements used in sensing systems and are classified under 900219. However, if they include electronic transmitting and receiving modules, they may be classified as complete machines. How to inquire about the tax rate for 900219? The tax rate must be inquired according to the latest customs tariff, which can be checked through the General Administration of Customs website or the declaration system. Different countries of origin may apply different agreement tax rates. What documents are required for classification under 900219? Generally, contracts, invoices, packing lists, product manuals, etc. are required to prove that the goods are mounted vehicle-mounted optical lenses. Classification basis may be provided when necessary.
