Aluminum Alloy T-Slot Extrusion
Extruded T-slot profiles from aluminum alloy 6063-T5, used for modular framing in machine guards and workstations. Classified under HTS 7604.29.1090 as 'other' profiles of aluminum alloys, featuring complex T-shaped cross-sections not fitting specific shapes. Meets alloy definition with iron plus silicon exceeding pure aluminum limits.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed as hollow T-slot profiles
Hollow cross-sections shift to 7604.29.30 for hollow profiles of alloys.
If for industrial use as structural steel-like components
If marketed as finished building structures, may fall under iron/steel Chapter 73 equivalents, though material dictates aluminum.
If processed into plates or sheets post-extrusion
Cladding or flattening changes to 7606 for clad aluminum plates.

Import Tips & Compliance
• Include cross-sectional diagrams in entry docs to prove T-slot shape qualifies as 'other profile', not bar or rod
• Certify temper and alloy grade (e.g
• 6063-T5) to comply with aluminum alloy subheading requirements
• Watch for misdeclaration as parts; extrusions alone stay in 7604 unless assembled
