Incoloy 825 Cold-Finished Round Bar
Incoloy 825 is a high-nickel alloy steel (Ni 38-46%, Cr 19.5-23.5%) used for its excellent corrosion resistance in harsh environments. This cold-finished round bar falls under HTS 7228.50.50.05 as it is not further worked beyond cold-forming and qualifies as high-nickel alloy steel per Chapter 72 notes. Commonly used in chemical processing equipment and marine applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stainless steel composition dominates
High-nickel alloys meeting stainless steel criteria (specific Cr/Ni ratios) classify under Chapter 72 stainless headings instead of alloy steel.
If further worked with polishing or coating
Per Chapter 72 note, any polishing, coating, or chemical treatment beyond cold-finishing moves product to 'other bars and rods, not cold-formed.'
If machined into finished articles or parts
Cold-finished bars further processed into specific components (e.g., pump shafts) become articles of iron/steel under Chapter 73.

Import Tips & Compliance
• Provide mill test certificates confirming high-nickel alloy composition (typically >30% Ni) to verify classification under 7228.50.50.05
• Ensure documentation specifies 'cold-finished' status with no further surface treatments like coating or polishing to avoid reclassification
