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, Chapter 90 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 quantities.
• 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 classified as 90?

These goods share common characteristics such as high precision, high technical content, and reliance on optical, electronic, or mechanical principles, and are mainly used in scientific research, industrial production, healthcare, safety inspection, and other fields. Therefore, customs classify them under 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.

The first four digits 9030 represent:

Oscilloscopes, spectrum analyzers, and other instruments and devices for measuring or testing electrical quantities, excluding instruments under heading 9028; instruments and devices for measuring or testing α, β, γ, X-rays, cosmic rays, or other ionizing radiation; their parts and accessories.

The six-digit code HS code: 9030.20

Classification: Oscillators, spectrum analyzers, and other instruments and devices for measuring or testing electrical quantities, excluding instruments under heading 9028; instruments and devices for measuring or testing α, β, γ, X-rays, cosmic rays, or other ionizing radiation; their parts and accessories: Oscillators and oscilloscopes: Other oscillators and oscilloscopes

Meaning: This HS code covers instruments and devices for measuring or testing electrical quantities, such as oscillators and oscilloscopes, but excludes instruments used for specific purposes (such as those listed under heading 9028). It also includes instruments for detecting various ionizing radiations and their parts and accessories.

8-10 digit explanation: hscode: 9030201000 Classification: Oscilloscopes and other instruments and devices for measuring or testing electrical quantities, excluding instruments under Chapter 9028; instruments and devices for measuring or testing α, β, γ rays, X-rays, cosmic rays, or other ionizing radiation; their parts and accessories: → Oscilloscopes and oscillograms: → Other oscilloscopes and oscillograms Explanation: This HS code belongs to instruments and devices for measuring or testing electrical quantities, specifically categorized as oscilloscopes and oscillograms, and is classified as other oscilloscopes and oscillograms. It excludes instruments under Chapter 9028 and does not include instruments and devices for measuring or testing α, β, γ rays, X-rays, cosmic rays, or other ionizing radiation.
