Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If welded structural tubing
Lower cost welded ERW tubing serves same fabrication applications.
If non-circular cross section
Square/rectangular seamless tubing for frames uses other seamless profiles.
If motorcycle frame tubes
Pre-cut, pre-notched frame tubes classify as motorcycle frame parts.

Import Tips & Compliance
• Stock multiple wall thicknesses (1.65mm, 2.0mm, 3.0mm) under same HTS
• Provide yield strength certification (minimum 235 MPa for S235JR equivalent)
• Cut lengths ≤6m avoid 'in coils' classification issues
