Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as rope due to construction
Stranded products >16mm or rope-like plaiting go to 7312.10.10.
If cut to fixed lengths as finished components
Prefabricated prestressing elements become other steel articles.

Import Tips & Compliance
• Supply chemical composition and coating specs; avoid 'keg' misclassification irrelevant to Chapter 73
• Pitfall: over 16mm dimension excludes from 'wire' per notes

Textile-Covered Steel Strand for Concrete Prestressing
High-tensile steel strand, 12.7mm diameter, coated with polyethylene textile material for corrosion protection, specifically designed for prestressing post-tensioned concrete structures like bridges and buildings. It falls under HTS 7312.10.3010 due to its stranded steel construction, non-metallic covering, and explicit use in prestressing concrete. The textile covering enhances bonding and durability in concrete applications.
PE-Sheathed 15.2mm Prestressing Strand
7-wire steel strand with 15.2mm nominal diameter, sheathed in extruded polyethylene (non-metallic) for use in prestressed concrete beams and slabs. Classified under 7312.10.3010 as stranded wire for concrete prestressing covered with non-metallic material per Chapter 73 notes. The sheathing provides corrosion resistance during concrete embedding.
Polymer-Coated Post-Tensioning Cable Strand
Galvanized steel strand coated with polymer textile for corrosion protection in post-tensioned concrete floors and parking structures. HTS 7312.10.3010 applies to this stranded wire of steel, under 16mm, covered non-metallically, and designated for concrete prestressing. Polymer coating ensures long-term performance in alkaline concrete environments.
