The first two digits of the HS code starting with 90 generally represent optical, photographic, cinematographic, measuring, testing, analyzing, and control instruments and their parts and accessories.
Specifically, Chapter 90 includes the following main categories:
- Optical instruments: Such as eyeglasses, telescopes, microscopes, prisms, lenses, etc.
- Photographic and cinematographic instruments: Including cameras, video cameras, film, negatives, developing equipment, etc.
- Measuring and testing instruments: Including instruments for measuring length, weight, angle, temperature, pressure, flow rate, and other variables.
- Analytical instruments: Including spectrometers, chromatographs, analytical balances, etc.
- Control instruments: Including automatic control systems, industrial automation equipment, etc.
- Medical, surgical, and dental instruments: Including some precision optical and electronic instruments.
Why is it classified under 90?
These products share common characteristics such as high precision, high technical content, and reliance on optical, electronic, or mechanical principles. They are mainly used in scientific research, industrial production, medical care, and safety inspection fields. Therefore, customs classify them into Chapter 90 for easier management and statistics.
In summary, HS codes starting with 90 represent precision instruments and meters, typically used in situations requiring precise measurement, analysis, control, or observation.
