Harmonized System Code Classification

The first two digits of the HS code starting with 90 typically refer 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, film projectors, projectors, etc.
• Measuring instruments: Including instruments for measuring length, weight, volume, angles, temperature, pressure, and other parameters.
• 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 high 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 precision measurement, observation, analysis, and control.

First four digits explanation: HS code 9005

Classification: Telescopes, binoculars, other optical telescopes and their stands; other astronomical instruments and their stands (excluding radio astronomical instruments); parts and accessories.

Meaning: Covers various types of optical telescopes, including binoculars, monoculars, and other optical instruments used for astronomical observation. It also includes the stands, parts, and accessories of these instruments. It does not include instruments used for radio astronomical observation.

Six-digit explanation: HS code: 9005.80

Classification: Binoculars, monoculars, other optical telescopes and their mounting frames; other astronomical instruments and their mounting frames; but excluding radio astronomical instruments; parts and accessories.

Specific meaning: Refers to other instruments.

8-10 digit explanation: hscode: 9005804040 Classification: Binoculars, monoculars, other optical telescopes and mounting frames; other astronomical instruments and mounting frames; parts and accessories; --> other instruments --> optical telescopes --> other Explanation: This HS code belongs to the classification of binoculars, monoculars, or other optical telescopes, specifically categorized under "other instruments" under "optical telescopes" as "other." The difference from 9005.80.40.20 is that 9005.80.40.20 is specifically used for infrared light, while 9005.80.40.40 does not specify the type of light wave used, and belongs to other optical telescopes.

Examples of products: * Binoculars * Monocular telescopes * Optical telescopes * Parts and accessories for telescopes * Astronomical instruments * Parts and accessories for astronomical instruments
