Import Tips
• Label precisely as 'hairspring' with dimensional specs (wire dia <16mm) to match Chapter 73 wire definition
• Obtain advance rulings for exotic alloys to confirm iron/steel content vs. non-ferrous reclassification
• Monitor Swiss export certificates, as most hairsprings originate there with specific origin rules
