HS Code for Aluminium fasteners

Aluminium fasteners are classified under HS code 7616.99, which serves as the residual category for articles of aluminium not elsewhere specified or included. Unlike iron or steel fasteners, which have a dedicated heading in Chapter 73 (specifically 7318), the Harmonized System does not provide a specific four-digit heading for aluminium screws, bolts, nuts, or rivets. Consequently, these items are classified based on their constituent material under Chapter 76. According to the General Rules of Interpretation (GRI) 1 and 6, because these fasteners are finished articles made of aluminium and do not fall under the more specific descriptions of headings 7601 through 7615, they must be placed in the 'other' category. This classification applies to fasteners used in aerospace, automotive, and marine applications where the lightweight and corrosion-resistant properties of aluminium are preferred over heavier ferrous alternatives. The classification remains 7616.99 regardless of whether the fastener is threaded or non-threaded, provided it is made of an aluminium alloy.

Products Included

• Aluminium hex bolts and machine screws
• Aluminium nuts and locking washers
• Solid and blind aluminium rivets
• Aluminium threaded studs and spacers
• Aluminium cotter pins and circlips

Common Misclassification

The most frequent misclassification occurs with HS code 7318, which is strictly reserved for fasteners made of iron or steel. Importers often mistakenly use 7318 due to the similarity in product function. Additionally, 7616.10 is sometimes used incorrectly; this code is specifically for nails, tacks, staples (other than those of heading 8305), and similar articles. Threaded fasteners like bolts and nuts must remain in 7616.99.

FAQ

What is the HS code for Aluminium fasteners?

The primary HS code for aluminium fasteners, including bolts, nuts, and screws, is 7616.99.

Why are aluminium fasteners not classified under heading 7318?

Heading 7318 is restricted by the Section XV notes to articles made of iron or steel. Since these fasteners are made of aluminium, they must be classified within Chapter 76, specifically under the residual heading 7616.99.
