Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If shanks, threads or holes 6 mm diameter or less
Drops to 7616.10.60 subheading for smaller aluminum fasteners, purely dimensional criterion.
If classified as base metal mountings, fittings for furniture
Certain large aluminum screws used as furniture hardware may shift to Chapter 83 per functional use, not standalone fasteners.
If aluminum structures/components like door frames containing embedded bolts
If bolts are integral parts of larger aluminum architectural structures, classifies under 7610 as construction components.

Import Tips & Compliance
• Provide detailed engineering drawings showing thread/shank dimensions >6mm to support classification during CBP review
• Avoid common pitfall of classifying with hex head bolts under steel codes; highlight aluminum purity via spectrochemical analysis
• For alloyed aluminum, ensure documentation shows Al predominates over other elements per subheading note (b)
