Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If diameter 1.0 mm to 1.5 mm
Wire diameter determines subheading within same zinc-coated high-carbon category.
If supplied in bars/rods rather than wire form
Pre-drawn rod stock for springs classified under 7213 before final wire drawing process.
If further worked into finished springs
Completed spring products (not raw wire) classified by function in Chapter 73.

Import Tips & Compliance
• Measure diameter precisely - even slight variance over 1.0mm shifts to different subheading with higher duties
• Include tensile strength test results showing high-carbon properties; CBP often requests for spring wire
• Avoid declaring as 'spring steel' without chemical analysis - must prove nonalloy status
