Import Tips
• Verify the hairspring's material composition meets Chapter 73 iron/steel wire definition (cross-section ≤16mm) with supplier certifications
• Include detailed technical specs in documentation to distinguish from balance assemblies, avoiding misclassification
• Check end-use declarations for horological instruments to prevent reclassification as watch parts under Chapter 91
