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
