Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chain is welded rather than stud link
Welded link chain falls under a separate subheading, lacking the forged stud characteristic.
If for large-diameter tube chain used in oil rigs
If constructed from steel tubes rather than solid stud links, it shifts to Chapter 73 tube fittings.
If imported as part of an anchor assembly set
Sets including anchors and chain may classify under articles of iron/steel if not principally chain.

Import Tips & Compliance
• Verify chain grade certification (e.g
• ABS or Lloyd's Register) and provide mill test reports to prove compliance with strength standards
• Ensure links do not exceed 16 mm cross-section if claiming 'wire' status; measure precisely to avoid reclassification
