Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stainless steel composition
Corrosion-resistant lock wire typically stainless, classified in Chapter 72 stainless headings.
If pre-twisted safety wire sets
Wire imported in twisted pairs for locking classified as finished wire articles.
If carbon under 0.25% in same size
Low carbon wire in 1.0-1.5 mm diameter uses separate carbon content subheading.

Import Tips & Compliance
• Electro-galvanizing requires coating weight documentation (typically 15-30 g/m²)
• Confirm minimum 1.0 mm diameter; sub-1.0 mm shifts to 7217.20.30+ subheadings
• Aerospace applications may need additional FAA/DOD material specs beyond HTS classification
