Import Tips
• Include NIST-traceable frequency certificates to prove horological function during customs exam
• Separate hairsprings from movement kits in shipments to maintain individual spring classification
• Beware of minimum value declarations; low-value hairsprings may qualify for de minimis but require aggregation
