Import Tips
• Verify machine specs match statistical note definitions for semiconductor crystal grinders to avoid reclassification to Chapter 84 heading 8486
• Provide detailed technical documentation proving use in monocrystalline boule processing; common pitfall is insufficient end-use certification
• Ensure FDA or cleanroom compatibility certifications if for silicon/GaAs processing to meet import compliance
