7320.20.10.00 - Suitable for motor-vehicle suspension

This HTS category, 7320.20.10.00, specifically covers helical springs manufactured from iron or steel that are designed and suitable for use in motor-vehicle suspension systems. These springs are characterized by their coiled shape and are engineered to absorb shocks and vibrations, thereby providing a smoother ride and improved handling in automobiles, trucks, and other motor vehicles. The defining feature for classification under this subheading is the explicit suitability for motor-vehicle suspension, which implies specific design tolerances, load-bearing capacities, and material properties tailored for this application.

Distinguishing this category from its sibling, 7320.20.50, is crucial for accurate classification. While both subheadings fall under "Helical springs," 7320.20.10.00 is reserved exclusively for those intended for motor vehicles. The sibling category, "Other," would encompass all other helical springs of iron or steel not meeting the specific criteria for motor-vehicle suspension. This could include springs used in industrial machinery, furniture, appliances, or general engineering applications.

As a leaf node, 7320.20.10.00 has no further subcategories. Classification at this level is determined by the presence of the spring and its demonstrated suitability for motor-vehicle suspension. Importers and exporters should be prepared to provide evidence, such as technical specifications, product catalogs, or manufacturer declarations, to support the classification of goods under this specific subheading. The material composition being iron or steel, and the form being helical springs, are prerequisites for any classification within heading 7320, with this subheading providing the final level of specificity based on application.
