About heading 7320
Springs and leaves for springs, of iron or steel
Heading 7320 covers springs made of iron or steel, plus the flat leaves used to build leaf springs. The heading splits first by type: leaf springs and leaves therefor (7320.10), helical springs (7320.20), and all other springs such as hairsprings and flat spiral springs (7320.90). Within each group the rate depends on whether the spring is for motor vehicle suspension, the wire thickness, or the leaf thickness.
