Plain-language overview

Use HS-6 903220 when importing or exporting automatic manostats, which are devices that automatically regulate or control pressure in systems. For instance, if you are shipping a batch of automatic pressure regulators used in HVAC systems, this code is appropriate.

This code specifically applies to manostats, distinguishing them from other regulating instruments like thermoregulators or flow controllers, which fall under different HS codes. If you're dealing with a temperature control device, you would look at HS-6 903210 instead.

Automatic manostats are crucial in various applications, including industrial processes and automotive systems, where maintaining specific pressure levels is essential. They often come in forms such as digital pressure switches or mechanical pressure gauges.

When classifying your products, ensure they meet the criteria for automatic operation, as manual devices would not qualify under this HS-6. If your product is a manually operated pressure gauge, you should consider a different classification.
