HS Code for Steel fasteners

Steel fasteners are classified under HS code 7318.19, which is situated within Chapter 73 of the Harmonized System, covering articles of iron or steel. Heading 7318 specifically addresses screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter-pins, washers, and similar articles. The classification logic is based on the presence of threading and the specific function of the fastener. Subheading 7318.19 is a residual category for threaded articles that are not specifically named in other subheadings like 7318.11 (coach screws) or 7318.15 (other screws and bolts). To be classified here, the product must be made of iron or non-stainless steel and feature mechanical threading designed to secure components together. The material composition is critical; if the fastener were made of stainless steel, it would still fall under 7318 but might require different sub-classification depending on the specific regional tariff schedule. The manufacturing process typically involves cold heading or machining, followed by thread rolling. This code is essential for customs as it distinguishes general-purpose fasteners from specialized automotive or aerospace components that might fall under different chapters.

Products Included

Common Misclassification

Confusion often arises between 7318.19 and 7318.15. While 7318.15 covers specific types of screws and bolts, 7318.19 acts as the "other" category for threaded fasteners that do not fit the precise definitions of the preceding subheadings. Importers often mistakenly use 7318.15 for all bolts, but if the bolt has unique features or is part of a specialized assembly not covered by 7318.15, 7318.19 is the correct legal classification. Additionally, non-threaded fasteners like rivets or washers must be classified under 7318.21 through 7318.29, and stainless steel variants often require 7318.15 or 7318.16 depending on the specific item.

FAQ

What is the HS code for steel fasteners?
