17-4PH Stainless Steel Sheet
Precipitation-hardening stainless steel sheet with approximately 4% nickel and 3.5% molybdenum, width under 600 mm, used in aerospace components. Falls under HTS 7220.90.0010 due to its stainless steel composition, flat-rolled form less than 600 mm wide, nickel content between 0.5-24%, and molybdenum 1.5-5%. Not further worked beyond basic rolling.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If width 600 mm or more
Flat-rolled stainless steel shifts to heading 7221 when width reaches 600 mm or greater, regardless of alloy content.
If electrolytically coated or further worked
Surface treatments like metal coating move it from basic flat-rolled to 'other bars and rods' categories under 7222.
If nickel content 0.5% or less
Excludes from 7220's nickel subheading; flat-rolled stainless without significant nickel falls under Chapter 72 non-nickel stainless provisions.

Import Tips & Compliance
• Provide mill test certificates verifying exact nickel (0.5-24%) and molybdenum (1.5-5%) content to avoid reclassification
• Ensure product is not further worked like coated or polished
• Watch for width measurements under 600 mm to prevent shifting to wider HTS codes
