Import Tips
• Provide dimensional tolerance certificates (e.g
• ISO 286) critical for boule grinding precision
• Label with 'semiconductor grade' to distinguish from general industrial bearings during customs review
• Avoid common pitfall of missing RoHS compliance docs for electronics manufacturing imports
