0.45% Carbon Round Steel Wire for Spring Manufacturing from China
Round wire of nonalloy steel containing 0.45% carbon by weight, not plated or coated, and polished for enhanced surface finish. Classified under HTS 7217.10.80.20 as iron or nonalloy steel wire with 0.25-0.6% carbon, round cross-section, and 'other' specifications not meeting higher-strength categories. Used primarily in compression and extension spring production.

Import Tips
• Provide mill test certificates verifying carbon content between 0.25-0.6% and nonalloy composition to avoid reclassification
• Ensure wire diameter and round cross-section documentation matches 'other round wire' specs; common pitfall is misstating polish as coating
• Declare exact yield strength if near high-strength thresholds to prevent disputes under Chapter 72 notes
