HS-6 · Subheading
903039
Instruments and apparatus; for measuring or checking voltage, current, resistance or power, with a recording device (excluding multimeters)
Heading 9030 — Instruments, apparatus for measuring, checking electrical quantities not meters of heading no. 9028; instruments, apparatus for measuring or detecting alpha, beta, gamma, x-ray, cosmic and other radiations
Chapter 90: Optical, photographic, medical instruments
Plain-language overview
Use HS-6 903039 when importing or exporting instruments designed to measure or check electrical quantities like voltage or current, specifically those equipped with a recording device. An example would be a data logger that records voltage fluctuations over time.
This code specifically excludes multimeters, which are classified under a different HS line. If you have a device that can measure multiple electrical parameters but does not record data, you would need to look at HS-6 903031 instead.
Instruments under this classification are typically used in laboratories, electrical engineering, and research environments. They can include devices like oscillographs or recording ammeters that provide continuous data output.
When considering this HS code, ensure your product is not just a simple measuring device but one that captures and records data. This distinction is crucial for proper classification and compliance with customs regulations.
