Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If deformed or ribbed for concrete
Deformations during rolling qualify as note (c) reinforcing, to Chapter 73.
If other alloy >0.3% carbon
Duplex high-strength variants may fit other Chapter 72 alloy steel wires.
If imported assembled with rebar forms
Complete reinforcing structures classify as Chapter 73 steel structures.

Import Tips & Compliance
• PREN value certification (pitting resistance) distinguishes duplex from standard 300-series for proper duty
• Black annealed finish? Confirm no 'further worked' oil/phosphate coatings
• Avoid bundling with rebar; separate entries prevent set classification issues
