Import Tips

• Verify core specifications including winding turns, wire gauge, and material composition match transformer incorporation requirements to avoid reclassification as finished inductors

• Provide manufacturer datasheets proving the core is wound and solely for transformer assembly, as incomplete documentation often leads to duty reassessment

• Check for restrictions on electrical components from certain origins; declare insulation class and voltage rating accurately to prevent holds
