Import Tips

• Verify compatibility certification showing sole use with 8501.64.0110 generators via manufacturer specs or engineering drawings

• Include detailed bills of materials (BOM) proving the part's principal function in wind turbine alternator power conversion systems

• Avoid misclassification by distinguishing from general-purpose capacitors; provide evidence of voltage/current ratings matching ≥5 MVA alternators
