High-Carbon Lock Wire 1.0mm from Canada
1.0mm diameter drawn wire of nonalloy steel with 0.7% carbon, used in safety-critical aerospace and automotive locking applications to prevent fastener loosening. HTS 7217.90.50.90 applies to this other high-carbon (>0.6%) nonalloy wire not plated or further worked. Provides superior shear strength for vibration-prone environments.

Import Tips
• Certify exact carbon analysis and tensile properties (typically 1800-2200 MPa); aerospace specs like MS20995 require traceability
• No surface treatments allowed in this code—declaring coated wire risks 7217.20 duties
• Common issue: incorrect diameter measurement leading to wrong statistical suffix
