High-Carbon Spring Steel Wire from Canada
Round wire made from nonalloy steel containing 0.6% or more carbon by weight, typically used in manufacturing mechanical springs for automotive suspensions and industrial machinery. It falls under HTS 7217.90.50.90 as iron or nonalloy steel wire with high carbon content, not further worked beyond basic drawing. The elevated carbon level provides essential high tensile strength and elasticity required for spring applications.

Import Tips
• Verify carbon content certification from mill test reports to confirm ≥0.6% for this subheading; ensure wire diameter and tensile strength specs match declared use
• Provide accurate documentation of nonalloy composition to avoid reclassification to stainless steel codes
• Watch for 'further worked' treatments like coating which shift to 7217.20
