Silico-Manganese Hot-Rolled Coil Rod for Spring Manufacturing from Mexico
Hot-rolled bars and rods of silico-manganese steel, wound in irregularly shaped coils, specifically designed for manufacturing industrial springs. This product falls under HTS 7227.20.00 due to its composition as silico-manganese alloy steel (containing silicon and manganese beyond ordinary steel limits) and hot-rolled form in coils. The alloy provides enhanced strength and wear resistance suitable for high-stress spring applications.

Import Tips
• Obtain mill test certificates verifying silico-manganese composition to confirm classification under 7227.20.00 and avoid reclassification as ordinary alloy steel
• Ensure proper coil weight documentation as coils over certain weights may trigger different handling or duty considerations
• Declare exact silicon and manganese percentages to prevent disputes over alloy steel definitions in Chapter 72 notes
