Import Tips
• Provide material certificates showing corrosion-resistant alloys suitable for chemical slurries
• Label as 'semiconductor processing parts' to distinguish from general industrial centrifuge components
• Watch for reclassification if bowl includes fixed nozzles, potentially becoming complete filtering apparatus
