Import Tips
• Clearly document that the grinder is for semiconductor wafers, not general metalworking, to avoid classification under Chapter 84.61
• Keep records of the machine's specifications to show it handles brittle mineral materials
• Consider whether the equipment qualifies for a duty deferral under the Customs Duty Deferral Program
