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
