Music Wire Piano String Steel
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If carbon content <0.6% by weight
Music wire with lower carbon classified in the <0.6% carbon subheading of 7217.10.
If alloy tool steel per note (e)
High-carbon music wire meeting tool steel definitions (e.g., specific Cr/C combos) goes to alloy wire heading 7228.
If twisted into finished rope or cable form
Twisted high-carbon steel wire ropes classified as stranded products in 7318.21, not basic wire.

Import Tips & Compliance
• 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
Related Products under HTS 7217.90.50.90
High-Carbon Spring Steel Wire
Round wire made from nonalloy steel containing 0.6% or more carbon by weight, typically used in manufacturing mechanical springs for automotive suspensions and industrial machinery. It falls under HTS 7217.90.50.90 as iron or nonalloy steel wire with high carbon content, not further worked beyond basic drawing. The elevated carbon level provides essential high tensile strength and elasticity required for spring applications.
0.8% Carbon Tire Bead Wire
High-carbon steel wire (0.8% carbon content) drawn into fine bronze-coated filaments but classified on base metal, used to reinforce tire bead cores for structural integrity. Falls under HTS 7217.90.50.90 as nonalloy iron/steel wire ≥0.6% carbon; minimal coating doesn't qualify as 'further worked' if not specified otherwise. Essential for preventing tire deformation under pressure.
High-Carbon Lock Wire 1.0mm
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.
C70 Steel Brush Wire
C70 grade (0.67-0.74% carbon) round nonalloy steel wire used for manufacturing industrial wire brushes, knotting brushes, and abrasive cleaning tools. Classified in HTS 7217.90.50.90 as other wire containing ≥0.6% carbon by weight, drawn but not further worked. High carbon content ensures stiffness and durability under abrasive conditions.
1.0% Carbon Welding Wire
High-carbon nonalloy steel wire with 1.0% carbon content, drawn for specialized welding electrode applications requiring high hardness deposits. HTS 7217.90.50.90 covers this other category as it exceeds 0.6% carbon threshold and lacks alloying elements. Used in hardfacing applications for wear resistance.
High-Carbon Needle Wire 0.5mm
0.5mm fine high-carbon (0.65%) nonalloy steel wire used in felting needles and industrial sewing needle manufacturing. Falls under HTS 7217.90.50.90 as drawn wire of iron/nonalloy steel ≥0.6% carbon, other category. Provides necessary sharpness retention and bending resistance.
