Import Tips
• Verify furnace operates without electric heating elements to avoid Chapter 85 classification; provide technical specs confirming semiconductor material processing use
• Include end-user certificates for potential duty exemptions under semiconductor programs
• Watch for misclassification as laboratory apparatus if scaled down
