Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS category, 7305.90.10.00, specifically classifies tubes and pipes of iron or nonalloy steel that have circular cross-sections and an external diameter exceeding 406.4 mm. These are "other" types of tubes and pipes not specifically detailed under more granular headings within 7305, but characterized by their material composition. The key criteria for inclusion are the material (iron or nonalloy steel), the circular cross-section, and the substantial external diameter.

This classification is distinguished from its sibling category, 7305.90.50.00, primarily by the material composition. While both cover "other" tubes and pipes of circular cross-section exceeding 406.4 mm in external diameter, this category is exclusively for those made of iron or nonalloy steel, whereas the sibling category is reserved for those made of alloy steel. The distinction between nonalloy and alloy steel is critical for accurate classification.

As this is a leaf node, there are no further subcategories. Therefore, classification under 7305.90.10.00 is definitive once the criteria of material (iron or nonalloy steel), circular cross-section, and external diameter greater than 406.4 mm are met, and the product is not otherwise specifically classified. Examples of such goods could include large diameter, welded or riveted steel pipes used in major infrastructure projects like water mains or oil and gas transportation where the material is not alloyed.
