More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If higher capacity variants
Output exceeding 40 MW moves to separate subheading despite similar design.
If functioning as hydraulic turbine
Liquid-driven turbines (water/hydraulic) classify under Chapter 8410, not steam/vapor.
If sold as complete generating set
If imported with integral generator for retail sale, classifies as electric generating set.

Import Tips & Compliance
• Include biomass fuel compatibility certifications for preferential duty treatments in sustainability programs
• Document pressure ratings (back-pressure vs condensing) accurately for correct statistical reporting
• Avoid classifying with auxiliary oil systems separately to prevent parts tariff application
