HS Code for Chromatograph

Chromatographs are classified under HS code 9027.20. Chapter 90 covers optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus. Heading 9027 is specifically for instruments and apparatus for physical or chemical analysis, such as polarimeters, refractometers, and spectrometers. Subheading 9027.20 is the specific designation for chromatographs and electrophoresis instruments. These devices work by separating mixtures into their individual components for identification or quantification. The classification applies regardless of whether the instrument is a gas chromatograph (GC) or a liquid chromatograph (LC), provided it functions on the principle of chromatography. These instruments are highly sophisticated and are used in laboratories for environmental testing, pharmaceutical analysis, and forensic science. The HS code covers the complete apparatus, including the injection system, the separation column housing, and the detection unit when presented as a functional unit.

Products Included

• Gas Chromatographs (GC)
• High-Performance Liquid Chromatographs (HPLC)
• Ion Chromatographs
• Thin-Layer Chromatography (TLC) equipment
• Size-Exclusion Chromatographs

Common Misclassification

Chromatographs are often confused with spectrometers, which fall under 9027.30. While many chromatographs use a mass spectrometer as a detector (GC-MS or LC-MS), the primary separation function usually dictates classification under 9027.20, though complex hybrid systems require careful GRI 3(b) analysis. They may also be misclassified under 9027.89, which is a catch-all for other instruments. Additionally, laboratory ovens used for drying samples should not be here; they belong in 8419.

FAQ

What is the HS code for chromatograph?

The standard HS code for chromatographs and electrophoresis instruments is 9027.20.

Are chromatography columns classified here?

No, individual chromatography columns are typically classified as parts and accessories under HS code 9027.90, unless they are made of glass, in which case they may fall under Chapter 70.
