Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If grain-oriented electrical steel
Silicon-electrical steel variants shift to specific electrical sheet subheadings.
If width under 600 mm
Narrower flat-rolled products (<600 mm) classified under preceding width-based headings.
If thickness ≥4.75 mm but <19 mm
Adjacent thickness category within same cold-rolled alloy steel grouping.

Import Tips & Compliance
• Include heat number traceability for composition verification during customs exam
• Ensure no 'further worked' treatments like phosphatizing that would require 7226 classification
• Measure thickness uniformly; variations exceeding 4.75 mm at any point trigger reclassification
