Import Tips
• Include annealing specifications; soft-drawn wire must specify temper to avoid valuation disputes
• Provide dimensional tolerance certificates (±0.01mm typical) to prevent reclassification
• Label as 'refined copper' explicitly; alloy trace elements over limits trigger Chapter 74 subheading shifts
