Sawn Miners' Diamonds for Diamond Wire Sawing from China
Simply sawn miners' diamonds prepared for embedding in diamond wire used in stone cutting and semiconductor slicing. These industrial rough diamonds under HTS 7102.21.10.20 feature the required toughness but lack gem transparency. Critical for marble quarrying and silicon wafer production.

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
