Import Tips

Verify CNC control certification and machine specifications to confirm classification under 8460.40.40, avoiding misclassification as non-NC honing machines

Include detailed technical datasheets showing lapping function for metal/cermets in import documentation to prevent reclassification

Check for dual-use restrictions as precision finishing equipment may require export licenses from origin country
