Harmonized System Code Classification

90开头 HS 编码的商品 typically belong to Optical, Photographic, Cinematographic, Measuring, Testing, Analyzing, and Control Instruments and Their Parts and Accessories.

Specifically, the 90 category covers the following main categories:

• Optical Instruments: Including glasses, telescopes, microscopes, prisms, lenses, etc.
• Photographic and Cinematographic Instruments: Including cameras, video cameras, movie projectors, projectors, etc.
• Measuring Instruments: Including instruments for measuring length, weight, volume, angles, temperature, pressure, etc.
• Testing and Analyzing Instruments: Including laboratory equipment, medical diagnostic equipment, chemical analysis instruments, etc.
• Control Instruments: Including automatic control devices, industrial automation equipment, etc.

Why is it 90?

These products are all related to precise measurement, observation, analysis, and control, and usually require a high level of technical content and professional knowledge. They play an important role in scientific research, industrial production, medical care, environmental protection, and other fields.

Therefore, customs classify these products into category 90 to facilitate the specialized management and statistics of these high-tech, high-value-added products.

In summary, the core characteristics of goods with HS codes starting with 90 are precise measurement, observation, analysis, and control.
