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, healthcare, safety inspection, and other 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.
