HS Code for Steel pins

Steel pins, specifically those of a non-threaded nature used for mechanical fastening or alignment, are classified under HS code 731829. This code serves as a residual or "basket" category for non-threaded articles of iron or steel that are not specifically named in other subheadings of the 7318.2 group. Heading 7318 covers a wide array of fasteners, and the 7318.2 series is dedicated to non-threaded items such as washers, rivets, and cotters. When a steel pin does not meet the specific definitions of a spring washer (731821), a standard washer (731822), a rivet (731823), or a cotter/cotter-pin (731824), it falls into 731829. This classification is essential for industrial pins used for alignment, pivoting, or locking mechanisms where no screw threads are present. The material must be iron or steel; pins made of other metals like brass or aluminum are classified under their respective material chapters (e.g., Chapter 74 or 76).

Common Misclassification

The most frequent misclassification for steel pins is 731824, which is specifically for cotters and cotter-pins. While many industrial pins look similar to cotters, 731824 is strictly for split pins or wedge-shaped cotters. Another common error is using 731700, which covers nails, tacks, and drawing pins; however, 731700 is intended for fasteners used in construction or stationery, not precision mechanical pins. Furthermore, safety pins and hairpins are excluded from this chapter and are classified under 7319 and 9615 respectively.

FAQ

What is the HS code for steel pins?

Non-threaded steel pins for industrial or mechanical use are classified under HS code 731829.

Are safety pins classified under this code?

No, safety pins are classified under HS code 731940, as they are considered sewing or travel notions rather than industrial fasteners.
