Music Wire Piano String Steel from Mexico
Precision-drawn high-carbon steel wire (0.6-1.0% carbon) used for piano strings and musical instrument wires, offering exceptional tensile strength and consistent pitch stability. Classified under HTS 7217.90.50.90 due to its nonalloy composition and carbon content exceeding 0.6% by weight, in drawn form without further working. The high carbon enables the necessary hardness and vibrational properties.

Import Tips
• Include detailed chemical analysis showing carbon ≥0.6% and absence of alloying elements; declare exact gauge and tensile strength
• Ensure no plating or coating applied, as that constitutes 'further worked' per Chapter 72 notes
• Common pitfall: misdeclaring as lower-carbon music wire leading to duty adjustment
