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
