Import Tips
• Verify wire cross-sectional dimension with caliper measurements and include test certificates to confirm 5.1-12.7mm range
• Provide engineering drawings specifying helical design to avoid misclassification as leaf springs
• Ensure material certification for iron/steel content to comply with Chapter 73 notes on wire definition
