7216.91.00.10 - Drilled, notched, punched or cambered

This HTS category, 7216.91.00.10, specifically classifies angles, shapes, and sections of iron or nonalloy steel that have undergone subsequent processing beyond their initial forming. The key defining characteristic of goods within this subcategory is the application of drilling, notching, punching, or cambering operations to flat-rolled products that have been cold-formed or cold-finished. These operations impart specific features or contours to the base shape, making them ready for particular assembly or structural applications.

This classification distinguishes itself from its sibling, 7216.91.00.90, which covers "Other" cold-formed or cold-finished shapes from flat-rolled products. While both fall under the broader category of other shapes from flat-rolled products, 7216.91.00.10 is reserved for those that have been mechanically altered through the aforementioned specific processes (drilled, notched, punched, or cambered). The sibling category would therefore encompass processed shapes that do not exhibit these particular modifications, or other forms of post-forming alteration not explicitly listed.

As this is a leaf node in the HTS structure, there are no further subcategories to introduce. Therefore, the classification concludes with the specific descriptions of these processed steel shapes. The emphasis for importers and exporters remains on identifying whether the cold-formed or cold-finished shape of iron or nonalloy steel has been subjected to drilling, notching, punching, or cambering to ensure correct classification under this specific tariff item.
