Aluminum Alloy T-Slot Extrusion from Japan

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.

Import Tips

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
