Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when thermal conductivity detector used instead of IR
Non-optical gas chromatographs classify separately.
If mounted as integral part of refinery process equipment
Machinery parts classify with principal machine.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Specify IR detector type (photoacoustic or NDIR) to justify optical classification
• Include ATEX/IECEx certification for hazardous location use
