1.2mm Heat-Treated High-Carbon Spring Wire
Round wire of nonalloy steel with 0.6% or more carbon content, heat-treated for enhanced tensile strength, and sized at 1.2 mm diameter. Classified under HTS 7217.10.80.30 due to its specific diameter range (1.0-1.5 mm), high carbon composition, and heat treatment without plating or coating. Used primarily in manufacturing coil springs for automotive suspensions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing less than 0.6% carbon
Lower carbon nonalloy steel wire falls under separate subheading regardless of heat treatment.
If plated or coated with zinc or other metal
Plated wire shifts to heading 7217.20, excluding uncoated/polished categories.
If made of alloy steel instead of nonalloy
Alloy steel wire (with specified alloying elements per Chapter 72 notes) classified in Chapter 72 heading 7229.

Import Tips & Compliance
• Certify exact carbon content (≥0.6%) and diameter measurement at entry to match HTS 7217.10.80.30; mismatches lead to reclassification
• Provide heat treatment process documentation (e.g
• quenching/tempering specs) as proof it's not merely polished
• Avoid rust/discoloration claims for duty reduction per Chapter 72 notes; inspect shipments pre-entry
