Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of high-speed steel
High-speed tool steels (with tungsten/molybdenum/vanadium) have separate subheading.
If stainless with >14.7% Cr
Stainless bars/rods shift to Chapter 72 stainless headings.
If electrolytically coated post-rolling
Metal coating constitutes 'further worked' per Chapter notes.

Import Tips & Compliance
• Include heat analysis certificates proving conformance to ball-bearing elemental limits
• Confirm not universal mill plate (width >150mm, thickness ≥4mm) per note (b)
• Segregate from high-strength steel which has different yield point requirements
