Import Tips
• Verify part compatibility with specific centrifuge models via manufacturer specs to avoid misclassification as machinery
• Include detailed engineering drawings and end-use statements for semiconductor processing to qualify for duty relief programs
• Ensure RoHS compliance certification as common pitfall in electronics-related centrifuge parts
