HS-6 · Subheading
903289
Regulating or controlling instruments and apparatus; automatic, other than hydraulic or pneumatic
Heading 9032 — Regulating or controlling instruments and apparatus; automatic type
Chapter 90: Optical, photographic, medical instruments
Plain-language overview
Use HS-6 903289 when importing or exporting automatic regulating instruments that are not hydraulic or pneumatic. This includes items like electronic temperature controllers used in industrial processes.
This code specifically covers instruments that automatically regulate or control various parameters, such as pressure, temperature, or flow. For instance, an automatic pressure regulator for gas systems falls under this classification.
In contrast, HS-6 903281 covers hydraulic or pneumatic regulating instruments, which are specifically designed for fluid control. If your product operates using hydraulic pressure, you would need to classify it under that code instead.
When dealing with automatic instruments, it’s important to ensure your product does not fall into the hydraulic or pneumatic categories, as this could lead to misclassification and potential customs issues.
