Overview

This HTS category, 7304.39.00.52, specifically classifies seamless tubes, pipes, and hollow profiles made of iron or non-alloy steel that have a circular cross-section. The defining characteristic for this classification is a wall thickness that falls within a precise range: greater than or equal to 12.7 millimeters (mm) but less than 19 mm. These products must also meet the criteria of their parent categories, including having an outside diameter of 190.5 mm or more but not exceeding 285.8 mm.

To differentiate this category from its siblings at the same level, it's important to focus on the wall thickness specification. Category 7304.39.00.48 covers similar seamless steel tubes and pipes with an outside diameter in the specified range but with a wall thickness *less than* 12.7 mm. Conversely, category 7304.39.00.56 encompasses those with a wall thickness of *19 mm or more*. Therefore, this specific node acts as an intermediate classification based solely on the wall thickness measurement between these two related categories.

As this is a leaf node in the HTS classification structure, there are no further subcategories. All relevant details for classifying goods under this code are contained within the existing hierarchical structure and the specific parameters outlined in the description, namely the material, form, cross-section, outside diameter range, and the precise wall thickness range. This level of detail ensures accurate customs declarations for seamless iron or steel pipes and tubes exhibiting these particular physical dimensions.
