7216.99.00.10 - Drilled, notched, punched or cambered

This HTS category, 7216.99.00.10, specifically classifies angles, shapes, and sections of iron or non-alloy steel that have undergone further processing through drilling, notching, punching, or cambering. These operations alter the basic profile of the steel article to facilitate its intended use, often in construction, fabrication, or assembly processes. Examples include steel angles with pre-drilled holes for bolting, or notched beams designed for specific joint configurations.

This category is distinguished from its sibling, 7216.99.00.90, which covers "Other" angles, shapes, and sections of iron or non-alloy steel. While both fall under the "Other" subheading within the broader category of angles, shapes, and sections, 7216.99.00.10 is reserved for those articles exhibiting specific mechanical modifications like drilling or punching, indicating a more advanced stage of preparation for use. The sibling category would encompass items that do not possess these distinct preparatory modifications.

As this node represents a leaf in the HTS classification structure, there are no further subcategories. The classification is complete at this level, focusing on the distinct physical characteristics of having been drilled, notched, punched, or cambered. The key determinant for classification here is the presence of these specific fabrication steps, rather than the raw shape or profile alone.
