Springs and leaves for springs, of iron or steel
14 declarable lines
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.
Products in this heading
- Leaf springs and replacement leaves for light truck and trailer suspension
- Coil springs for passenger car suspension struts
- Helical coil springs used inside mattresses and mattress supports
- Hairsprings for watches, clocks and instruments
- Compression springs for valves and machinery
- Torsion springs for hinges and garage doors
- Flat spiral springs for retraction mechanisms
How to choose the right subheading
- Type of spring: leaf spring or leaf, helical (coil) spring, or other spring such as a hairspring
- Whether the spring is suitable for motor vehicle suspension, and for leaf springs the vehicle G.V.W. in metric tons
- For leaf springs, whether individual leaves are 1.6 mm or more thick
- For helical springs, the cross-sectional dimension of the wire: under 5.1 mm, 5.1 mm or more but under 12.7 mm, or larger
- Whether the spring is of wire at all, which separates 7320.90.50 from 7320.90.10 hairsprings and other non-wire springs
Often confused with
- Heading 7318Spring washers and lock washers
Washers, including spring washers, are named in heading 7318 and are not classified as springs.
- Heading 9404Mattresses and mattress supports that contain springs
The finished mattress or support is classified in 9404; only the bare springs fall in 7320.
- Heading 7318Cotter pins and spring pins used as fasteners
These are fasteners named in 7318, not springs in the tariff sense.
- Heading 7326Bent wire clips and other simple iron or steel articles with no spring function
Articles that do not act as springs fall to the residual heading 7326.
