Import Tips
• Verify machine specifications confirm use for stone or mineral materials to avoid reclassification to 8460 for metalworking
• Include detailed technical manuals and end-use declarations in documentation to prove cold working of stone
• Check for CE marking or equivalent if originating from EU; common pitfall is undervaluing multi-axis CNC features
