Import Tips
• Provide engineering drawings showing integration with 8445 spindles to confirm 'solely or principally' use criterion
• Label with exact machine model compatibility (e.g
• Rieter or Zinser frames) to facilitate customs verification
• Avoid common pitfall of bulk packaging without part numbers, which triggers valuation disputes
