0.35% Carbon Polished Round Wire for Lock Wire
High-tensile round steel wire with 0.35% carbon content, polished but not coated, used in safety lock wiring for aviation and machinery. Falls under HTS 7217.10.80.20 due to its nonalloy composition, specific carbon range, round shape, and exclusion from high-strength steel definitions. Meets tensile requirements for locking fasteners without further working beyond polishing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If carbon 0.6% or more
Higher carbon content in nonalloy round wire uses subsequent subheading.
If imported as finished stranded wire
Stranded or cabled configurations classify under barbed wire/stranded provisions, not solid rod/wire.
If for alloy tool steel equivalent
If meeting tool steel note (e.g., specific Cr/C combos), shifts to alloy flat-rolled but wire form to 7228.

Import Tips & Compliance
• Submit chemical analysis reports confirming 0.25-0.6% carbon to distinguish from lower-carbon wires
• Avoid classifying polished wire as 'further worked' unless it involves Chapter 72 note treatments like coating; polishing alone stays here
• Check for rust or discoloration issues per Chapter notes—no duty reduction allowed
