Import Tips & Compliance
• Confirm the screw turbine's power rating (100 kW) and head range in the product documentation
• If the turbine is part of a complete generating set, check if the generator is classified separately under heading 8501
• Be prepared to demonstrate that the product is a water wheel, not a pump, to avoid misclassification
