7303.00.00.60 - Pressure pipe with an inside diameter of less than 356 mm

This HTS category, 7303.00.00.60, specifically covers pressure pipes manufactured from cast iron that have an inside diameter smaller than 356 millimeters. These pipes are designed to convey fluids or gases under pressure, distinguishing them from non-pressure applications. The material composition, being cast iron, is a key determinant for classification under Chapter 73.

Unlike its sibling category 7303.00.00.30, which is designated for soil pipes primarily used for drainage and waste, this category focuses on pipes intended for higher pressure systems such as water mains, industrial fluid transport, or gas distribution lines. The specified inside diameter of less than 356 mm is a crucial distinguishing feature that differentiates these pressure pipes from potentially larger diameter cast iron pipes.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification within 7303.00.00.60 relies directly on the material (cast iron), the intended use (pressure conveyance), and the specified dimensional criteria (inside diameter less than 356 mm). Importers and exporters should confirm these characteristics to ensure correct classification.
