Harmonized System Code Classification

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, 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, negatives, developing equipment, etc.
• Measuring and testing instruments: Including instruments for measuring length, weight, angle, temperature, pressure, flow, and other various measurements.
• Analyzing 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 90?

These goods share the common characteristics of high precision, high technical content, and reliance on optical, electronic, or mechanical principles, and are mainly used in scientific research, industrial production, medical care, safety inspection, and other fields. Therefore, customs classify them into category 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.
