Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for bars and rods of stainless steel, hot-rolled
Solid bars without hollow profile are in Chapter 72, not seamless tubes/pipes.
If threaded or drilled post-import
Finished tube or pipe fittings shift from raw hollow bar classification.

Import Tips & Compliance
• Provide material certification showing duplex microstructure to justify stainless steel classification
• Use ISPM-15 compliant packaging for bulk shipments to prevent quarantine issues
• Document outer diameter under 16mm if wire-like to avoid Chapter 73 wire headings
