HS-4 · Heading
9027 — Instruments and apparatus; for physical or chemical analysis (e.g. polarimeters, spectrometers), for measuring or checking viscosity, porosity, etc, for measuring quantities of heat, sound or light
Chapter 90: Optical, photographic, medical instruments
Plain-language overview
Use HS-4 9027 when importing or exporting instruments and apparatus designed for physical or chemical analysis, such as gas analyzers used in laboratories. These tools are essential for measuring properties like viscosity or light intensity in various scientific applications.
When deciding between subheadings, consider whether your product specifically analyzes gas or smoke. If it does, HS-6 902710 is appropriate. For chromatographs or electrophoresis instruments, you should use HS-6 902720 instead.
If your instrument utilizes optical radiations, check if it falls under HS-6 902730 for spectrometers or HS-6 902750 for other optical devices. This distinction is crucial for proper classification and compliance.
For instruments measuring physical properties like surface tension or heat, you can choose between HS-6 902781 for mass spectrometers and HS-6 902789 for exposure meters. Understanding these nuances will help ensure you select the correct code.
