Import Tips
• Require ISO 9001 or IATF 16949 certification from suppliers for quality assurance
• Declare as 'chemical element silicon' not 'semiconductor material' to prevent premature Chapter 85 classification
• Monitor for Section 301 tariffs if originating from China due to technology sector restrictions
