Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not round cross-section (e.g., square or flat)
Non-round stainless wire classified separately within heading 7223.
If made into finished springs
Assembled springs become finished articles under screws, bolts, and similar.
If wound into complete motor armatures
End-use as distributed parts for electrical machinery changes classification.

Import Tips & Compliance
• Include tensile strength test results proving spring temper without surface treatments
• Label spools clearly with alloy grade and diameter to facilitate CBP verification
• Avoid bundling with coated wires, as mixtures trigger separate tariff line entries
