HS Code for Densitometer

Densitometers are classified under HS code 9027.89, which covers instruments and apparatus for physical or chemical analysis. Specifically, these devices measure the optical density of a material by determining the degree of opacity or the amount of light absorbed or reflected by a surface. This classification is appropriate because the densitometer performs a quantitative analysis of light properties to provide data on the physical characteristics of a sample, such as the thickness of an ink layer or the exposure level of a photographic film. Heading 9027 is the designated category for instruments that check quantities of light, sound, or heat that are not specifically mentioned in other headings. These instruments are critical in the printing, photography, and medical radiography industries to ensure quality control and consistency in imaging and color reproduction.

Products Included

• Transmission densitometers for transparent materials
• Reflection densitometers for opaque surfaces
• Color densitometers for printing press control
• Scanning densitometers for laboratory analysis
• Bone densitometers (specifically those using optical analysis)
• Microdensitometers for high-resolution imaging

Common Misclassification

Densitometers are often confused with HS code 9026.80, which is used for density meters that measure the mass per unit volume of liquids or gases. While the names are similar, 9027.89 is for optical density (light), whereas 9026.80 is for fluid density. Additionally, spectrophotometers are sometimes misclassified here; however, if the device measures the full spectrum of light rather than just density, it may fall under 9027.30.

FAQ

What is the HS code for a densitometer?

The HS code for an optical densitometer used for light analysis is 9027.89.

Is a bone densitometer classified under 9027.89?

It depends on the technology. If it uses optical analysis, it may fall here, but most modern bone densitometers use X-rays and are classified under HS code 9022.14.
