Import Tips
• Provide COSC chronometer certification references to establish precision watch end-use justifying chapter 91
• Declare exact alloy composition (Nivarox, Elinvar) as undervaluation of specialty materials triggers audits
• For sets with balance wheels, use GRI 3 rules carefully; individual springs maintain 9114 classification
