Harmonized System Code Classification

The first two digits "90" in the HS code represent Optical, photographic, cinematographic instruments, optical elements and related instruments.

Specifically, this major category includes the following main contents:

• Optical instruments: Including telescopes, microscopes, prisms, lenses, filters, camera lenses, etc.
• Photographic equipment: Including cameras, developing equipment, film, photographs, slides, etc.
• Cinematographic equipment: Including video cameras, video recorders, video tapes, etc.
• Related instruments: Including projectors, light meters, developing machines, enlargers, reducers, movie projectors, etc.

Reason for classification:

Products in this category are all based on optical principles, using light for imaging, recording, measuring, or processing. Therefore, they are classified into the category of "Optical, photographic, cinematographic instruments." The core functions of these products are all related to optical technology, whether for observation, recording, or processing images, they all rely on optical components and optical principles.

If you want to know more specific classification, please provide more detailed HS codes (e.g., 9001, 9002, etc.), or provide a specific product description, I can help you analyze further.
