Import Tips
• Reference statistical note (a)(ii)(C) for wafer grinders in documentation to support semiconductor end-use
• Provide cleanroom compatibility certifications (e.g
• low particle generation) for customs validation
• Declare vacuum-compatible materials if applicable to avoid reclassification as Chapter 90 apparatus
