0.45% Carbon Round Steel Wire for Spring Manufacturing
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If carbon content under 0.25%
Lower carbon nonalloy round wire shifts to preceding subheading in the same tariff line.
If plated or coated with zinc
Plating changes classification from 'not plated or coated' to Chapter 72 plated steel wire heading.
If made of alloy steel
Alloy steel wire (per Chapter 72 note definitions) moves out of nonalloy 7217 to Chapter 72 alloy wire provisions.

Import Tips & Compliance
• 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
