Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloy steel construction
Presence of alloying elements classifies under alloy steel provisions in the same heading.
If imported as prefabricated structural articles
Finished structural steel assemblies (e.g., trusses) go to heading 7326, not raw tubes.
If circular cross-section
Circular welded profiles are excluded from noncircular 7306.69 and classified separately.

Import Tips & Compliance
• Label with exact dimensions, steel grade (e.g
• ASTM A500 Gr.B nonalloy), and 'welded' status for CBP review
• Use dimensional reports from accredited labs to prove noncircular shape and wall thickness over 4mm
