Import Tips

• Verify statistical suffix .65.60 applies specifically to semiconductor processing equipment per Chapter 84 notes

• Provide manufacturer specs confirming use in crystal growers/pullers to avoid reclassification to general machinery parts

• Include material certificates showing compatibility with vacuum/high-temperature semiconductor environments
