HS Code for Cotter pins

Cotter pins are classified under HS code 7318.24, which falls under the category of non-threaded fasteners made of iron or steel. Chapter 73 covers articles of iron or steel, and heading 7318 specifically includes screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter-pins, washers, and similar articles. The structure of heading 7318 is divided between threaded articles (7318.11 through 7318.19) and non-threaded articles (7318.21 through 7318.29). Since cotter pins function by mechanical deformation (such as bending the tines) or through tension rather than via a helical thread, they are categorized in the non-threaded section. Subheading 7318.24 is the specific designation for cotters and cotter-pins, ensuring they are distinguished from other non-threaded fasteners like rivets or spring washers. This classification applies to various designs of cotters, provided they are made of iron or steel and are not threaded. The material composition is the primary driver for the chapter selection, while the specific mechanical design dictates the subheading.

Common Misclassification

Cotter pins are sometimes misclassified under 7318.23 (rivets) or 7318.29 (other non-threaded fasteners). They may also be confused with 7318.15 if the user mistakenly identifies them as a type of bolt. If the pin is made of copper, it must be classified under 7415.29 instead of the iron/steel code.
