Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chromatographic separation principle used
Gas chromatographs classify separately even for similar end uses.
If sold as complete continuous emission monitoring system (CEMS)
Integrated systems with data acquisition classify as complete machines.
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
• Provide EPA Method 320 validation data for customs verification of stack gas application
• Label clearly as 'optical FTIR analyzer' to distinguish from mass spec under different codes
