0.35% Carbon Polished Round Wire for Lock Wire from Canada
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.

Import Tips
• 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
