7317.00.20.00 - Not threaded

This HTS category, 7317.00.20.00, specifically covers articles such as nails, tacks, drawing pins, staples, and similar fasteners made from iron or steel that are *not threaded*. This includes common smooth nails, pins, and staples that rely on friction and material penetration for holding power, rather than screw-like engagement. The primary characteristic is the absence of a helical ridge along the shaft.

This classification is distinct from its sibling category, 7317.00.30.00, which covers *threaded* articles of the same base material. The presence or absence of threading is the key differentiator. While both categories encompass similar types of fasteners, the method of attachment and design of the fastener's shaft are what dictate classification between these two headings.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the focus for classification purposes under 7317.00.20.00 is solely on identifying articles made of iron or steel that are essentially unthreaded. Examples within this category would include common finishing nails, brads, upholstery tacks, and standard corrugated nails or staples that do not feature any helical grooves.
