Harmonized System Code Classification

The first two digits "90" represent Optical, photographic, cinematographic, measuring, testing, analyzing, and control instruments and their accessories; clocks and timepieces.

More specifically, this chapter includes the following main categories:

• Optical instruments: Including telescopes, microscopes, prisms, lenses, photographic lenses, projectors, etc.
• Photographic and cinematographic instruments: Including cameras, video cameras, movie cameras, developing machines, film, etc.
• Measuring, testing, and analyzing instruments: Including balances, length measuring instruments, flow meters, thermometers, pressure gauges, analytical instruments, etc.
• Control instruments: Including automatic control instruments, alarms, signal devices, etc.
• Clocks and timepieces: Including various types of clocks (mechanical clocks, electronic clocks, wristwatches, wall clocks, etc.) and timers.

In short, products under the "90" chapter are mainly used in scientific research, industrial production, healthcare, environmental protection, safety inspection, and time measurement fields.

If you want to know more detailed classification, please provide a more specific HS code, such as "9001" or "9010".
