Import Tips & Compliance
• Obtain a certificate of analysis confirming the oxygen-free grade and copper purity to support the refined copper classification
• Be aware that audio-grade wire may be subject to consumer product regulations, but these do not affect tariff classification
• Declare the wire as bare or uncoated to avoid misclassification as insulated wire
