Import Tips
• Provide manufacturer specs showing compatibility with both 8471 and 8473 machines to avoid single-use classification
• Label with exact part numbers and machine references; customs often requests proof of multi-heading suitability
• Use ESD-safe packaging and include material safety data for cleanroom compatibility during import inspection
