Import Tips
• Specify 'diamond wire feedstock' end-use on commercial invoice to support industrial classification
• Separate shipments of sawn vs cleaved miners' diamonds to match exact statistical suffixes
• Watch for re-export requirements under KP if processing occurs before final US consumption
