Overview

This HTS category, 7318, encompasses a wide array of fasteners and similar articles manufactured from iron or steel. It specifically includes items such as screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter pins, and washers, including spring washers. The defining characteristic for inclusion in this heading is their construction from iron or steel, serving the fundamental purpose of joining, securing, or fastening other objects.

While other HTS chapters and headings deal with various manufactured goods, Chapter 73 focuses exclusively on articles of iron or steel. This means that fasteners made from other base metals, such as aluminum or copper, would fall under different HTS headings. Furthermore, within Section XV, this heading is distinct from categories covering unwrought or semi-finished base metals (Chapter 72 for iron and steel) or more complex manufactured articles where the fastener function is not the primary characteristic.

The subcategories within 7318 are designed to differentiate between fasteners based on their construction. The distinction between "Threaded articles" and "Non-threaded articles" is crucial for classification. Threaded articles, such as screws, bolts, and nuts, are characterized by their helical ridges designed to engage with a corresponding internal or external thread. Non-threaded articles, like rivets and cotters, achieve their fastening function through deformation, friction, or interlocking mechanisms without relying on screw threads. This division aids in the precise identification and tariff treatment of specific types of fasteners.
