HS-4 · Heading
9025 — Hydrometers and similar floating instruments, thermometers, pyrometers, barometers, hygrometers and psychrometers, recording or not
Chapter 90: Optical, photographic, medical instruments
Plain-language overview
Use HS-4 9025 when importing or exporting hydrometers, thermometers, or similar measuring instruments. For example, if you're shipping a liquid-filled thermometer for direct reading, this heading applies. Knowing the correct HS-6 code is crucial for compliance and accurate duty assessments.
The HS-6 subheading 902511 specifically covers liquid-filled thermometers and pyrometers designed for direct reading. If your product is a digital thermometer or a non-liquid filled device, you should consider 902519 instead. This distinction is vital for proper classification and duty calculations.
For instruments that combine features, such as a hygrometer that also records temperature, look at 902580. This line includes various combinations of instruments but excludes those that are not combined. If your product includes parts or accessories, 902590 is the appropriate choice.
