Import Tips
• Include polishing rate data and surface roughness specs (Ra values) to demonstrate material removal function
• Avoid describing as 'cleaning equipment' in docs, as this shifts classification away from machine tools
• For EU imports, ensure Machinery Directive compliance documentation is complete
