Import Tips
• Verify the spring is explicitly for watch movements (under 12mm thick, 50mm wide) to avoid reclassification under chapter 85
• Provide manufacturer specs confirming compatibility with watch balance wheels; retain movement assembly diagrams
• Check for base metal parts exclusion per chapter note 1(c); hairsprings qualify as watch-specific
