Import Tips
• Provide evidence of enterprise-grade specs (e.g
• MTBF ratings) to distinguish from consumer drives during classification review
• Label shipments clearly as 'magnetic disk drive units' and include HS code on commercial invoice to prevent misclassification
• Check for ITAR restrictions if drives contain encryption features exceeding basic levels
