Galvanized High-Carbon Steel Music Wire 0.8mm
Round galvanized wire with 0.6% or more carbon content and diameter of 0.8mm, used primarily for manufacturing piano strings and guitar strings. Classified under HTS 7217.20.45.30 due to its nonalloy steel composition, zinc coating, high carbon content, and sub-1.0mm diameter. The high carbon provides essential tensile strength for musical applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not plated or coated with zinc
Uncoated high-carbon round wire <1.0mm falls under 7217.10, as zinc plating specifically directs to 7217.20.
If alloy steel composition per chapter note (e)
High-carbon wire meeting tool steel definitions moves to Chapter 72 alloy steel wire headings.
If imported as finished stranded cable
Stranded or twisted configurations are classified as wire rope rather than individual wire.

Import Tips & Compliance
• Provide mill test certificates verifying carbon content ≥0.6% and diameter <1.0mm to avoid reclassification
• Ensure zinc coating weight documentation meets ASTM A641 standards; common pitfall is insufficient plating verification
• Declare as nonalloy steel - alloying elements must not exceed chapter note limits to prevent Chapter 72 heading shift
