HS Code for Optical measuring instrument

Optical measuring instruments are classified under HS code 9031.49. Heading 9031 is dedicated to measuring or checking instruments, appliances, and machines that are not specified or included elsewhere in Chapter 90. The sub-heading 9031.4x specifically identifies instruments that utilize optical phenomena—such as light reflection, refraction, interference, or diffraction—to perform their measuring or checking functions. The 'other' designation in 9031.49 is used for a wide variety of sophisticated industrial and scientific tools that do not fit into the more specific 9031.41 (for inspecting semiconductor wafers). These instruments are essential in quality control and precision engineering, as they allow for non-contact measurement of dimensions, surface roughness, or alignment. The classification is driven by the primary function of the device: if the optical component is the means by which a measurement is taken, 9031.49 is the correct code.

Products Included

• Optical profile projectors
• Laser distance measuring tools (industrial)
• Optical comparators
• Interferometers for surface analysis
• Coordinate measuring machines (CMM) with optical sensors
• Optical alignment telescopes

Common Misclassification

These instruments are often confused with HS code 9013.80, which covers general optical appliances. The distinction lies in the function: if the device measures a specific value (length, angle, etc.), it belongs in 9031. Another common misclassification is 9027.50, which covers instruments using optical radiations for physical or chemical analysis (like spectrometers). If the tool measures physical dimensions, use 9031; if it analyzes the composition of a substance, use 9027. Additionally, simple hand tools like calipers are in 9017, even if they have a small digital display.

FAQ

What is the HS code for optical measuring instrument?

The standard HS code for optical measuring or checking instruments not specified elsewhere is 9031.49.

Is a laser level an optical measuring instrument?

Yes, laser levels used for alignment and checking horizontal or vertical planes are typically classified under 9031.49 as optical checking instruments.
