Import Tips & Compliance

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
