Import Tips
• High precision requires calibrated measurement tools; submit photos/micrographs of cross-section for verification
• Avoid coiling patterns that suggest pre-forming, which could shift to finished article classification
• Carbon content certification critical; horology-grade wire often at exact 0.6-1.0% threshold
