Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If complex non-round twisted profiles
Highly irregular cross-sections exclude from 'essentially round' provision.
If corrugated pipe-style chain
Corrugated steel structures classify under pipe/tube headings.
If copper alloy construction
Nonferrous chain moves to appropriate Chapter 74 heading.

Import Tips & Compliance
• Specify twist angle (typically 90°) in technical drawings for classification
• Torsion testing certifies twist maintains round cross-section integrity
• Distinguish from straight link via 360° rotation measurement
