Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cold-drawn with tensile strength >600 MPa
Specific mechanical properties trigger statistical suffixes within cold-drawn iron/steel tubes.
If over 16mm cross-section dimension
Exceeding wire dimension limit (16mm) shifts from potential Chapter 72 hollow bars to tubes.
If of carbon steel, not alloy
Lack of alloying elements >1.5% total moves to carbon steel seamless tube classifications.

Import Tips & Compliance
• Include NACE MR0175 compliance if for oil/gas to prove heat-resisting corrosion resistance
• Ensure no surface treatments that could reclassify as finished tubes under other provisions
