7312.10.90.30 - With a diameter not exceeding 9.5 mm

This classification covers ropes, cables, and cordage made from iron or steel, which are not electrically insulated and are not stranded wire. Specifically, it encompasses items within the "Other" category of ropes, cables, and cordage that are galvanized. The defining characteristic for this particular sub-classification is that the diameter of the rope, cable, or cordage must not exceed 9.5 mm.

This category is distinguished from its sibling category, 7312.10.90.60, by the precise measurement of its diameter. While both are galvanized ropes, cables, and cordage other than stranded wire, this sub-category is exclusively for those with a diameter of 9.5 mm or less. The sibling category, conversely, covers similar items with a diameter exceeding 9.5 mm. This distinction is critical for accurate customs declarations, as it relies on a specific physical measurement to differentiate the products.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the focus remains on the precise definition and exclusion criteria: galvanized iron or steel ropes, cables, and cordage, excluding stranded wire, with a diameter not exceeding 9.5 mm. Examples of items that would fall under this classification include smaller diameter galvanized steel cables used for general purposes, mooring lines, or securing applications where such a size limitation is specified.
