7216.10.00 - U, I or H sections, not further worked than hot-rolled, hot-drawn or extruded, of a height of less than 80 mm

This HTS category, 7216.10.00, specifically covers angles, shapes, and sections of iron or non-alloy steel that are U, I, or H-shaped. These items are defined by being not further worked than hot-rolled, hot-drawn, or extruded, and crucially, they possess a height of less than 80 mm. This precise dimensional constraint is a key identifier for this particular classification.

When differentiating from sibling categories, it's important to note the cross-section shape and dimensions. For instance, while other categories within 7216.10 also cover hot-rolled, hot-drawn, or extruded sections, they may pertain to L or T shapes, or U, I, or H sections with a height of 80 mm or more. Furthermore, sections that are cold-formed or cold-finished fall under different headings entirely, regardless of their cross-sectional profile.

The subcategories within 7216.10.00 provide further refinement based on the specific shape. The 7216.10.00.10 subcategory is dedicated to U-shaped sections, acknowledging their commonality and distinct usage. The remaining U, I, or H sections that do not fit the U-section description are captured under the broader "Other" classification, 7216.10.00.50, ensuring comprehensive coverage within the defined parameters of this code.
