Harmonized System Code Classification

The first two digits of the HS code starting with 90 typically represent optical, photographic, cinematographic, measuring, testing, analyzing, and control instruments and their parts and accessories.

Specifically, the 90 category includes the following main categories:

• Optical instruments: Including eyeglasses, telescopes, microscopes, prisms, lenses, etc.
• Photographic and cinematographic instruments: Including cameras, video cameras, film projectors, projectors, etc.
• Measuring and testing instruments: Including instruments for measuring length, weight, angle, temperature, pressure, flow, and other various measurements.
• Analyzing instruments: Including spectrometers, chromatographs, mass spectrometers, etc.
• Control instruments: Including automatic control systems, industrial automation equipment, etc.
• Medical, surgical, and dental instruments: Including some optical and precision instruments used in the medical field.

Reason for classification:

These products all have precision optical, electronic, or mechanical principles, used for acquiring, measuring, analyzing, or controlling information. They usually require high technical content and manufacturing precision, so they are classified under category 90.

In summary, HS code category 90 represents high-tech, precision instruments, widely used in scientific research, industrial production, and medical care.

First four digits explanation: 9001

Optical fibers and fiber bundles; other optical fibers cables (excluding those of heading 8544); sheets and plates of polarizing materials; lenses (including contact lenses), prisms, mirrors, and other optical elements, of any material, not mounted, but not optically worked glass elements.

Six-digit explanation: HS code: 9001.30

Classification: Optical fibers and fiber bundles; optical fiber cables (other than those of heading 8544); sheets and plates of polarizing materials; lenses (including contact lenses), prisms, mirrors, and other optical elements, of any material, not mounted, but not optically worked glass elements:

Specific meaning: Includes contact lenses.

Eight to ten-digit explanation: HS code: 9001300000

Classification: Optical fibers and fiber bundles; optical fiber cables (other than those of heading 8544); polarizing sheets and plates of any material other than optically worked glass; lenses (including contact lenses), prisms, mirrors, and other optical elements, of any material, not mounted.

Explanation: This HS code covers optical fibers and fiber bundles, optical fiber cables (other than those of heading 8544), and polarizing sheets and plates, as well as lenses (including contact lenses), prisms, mirrors, and other optical elements made of any material other than optically worked glass, and not mounted.

Examples of products under this HS code:

• Contact lenses
• Optical lenses (e.g., camera lenses, telescope lenses)
• Mirrors (e.g., optical mirrors, reflective surfaces)
• Prisms (e.g., optical prisms used in cameras or spectrometers)
• Polarizing filters
• Fiber optic cables (excluding those in heading 8544)
• Optical fibers and fiber bundles
