7320.10.30.00 - To be used in motor vehicles having a G.V.W. not exceeding 4 metric tons

This HTS classification, 7320.10.30.00, specifically covers leaf springs and their constituent leaves made of iron or steel, which are designed for use in the suspension systems of motor vehicles. A key defining characteristic for inclusion in this subcategory is that the intended motor vehicle must have a Gross Vehicle Weight (GVW) not exceeding 4 metric tons. This limitation is crucial for differentiating these components from those used in heavier-duty vehicles, which would fall under different classifications.

Distinguishing this category from its sibling, 7320.10.60, is the explicit mention of suitability for motor vehicles with a GVW not exceeding 4 metric tons. The sibling category, "Other," would encompass leaf springs and leaves not meeting this specific weight limitation, or those intended for applications other than motor vehicle suspension, such as industrial machinery or general mechanical equipment. Therefore, classification here hinges on both the product's form (leaf spring or leaf) and its intended application within a specific weight class of motor vehicles.

As this is a terminal node within the HTS structure, there are no further subcategories. The classification is complete upon meeting the criteria of being an iron or steel leaf spring or leaf specifically intended for use in motor vehicles with a GVW not exceeding 4 metric tons. Examples of vehicles fitting this description include many passenger cars, light trucks, and some vans.
