17-4 PH Precipitation Hardening Stainless Steel Bloom
Rectangular bloom of 17-4 PH stainless alloy steel used in valves and fittings, with chromium ~17% and nickel ~4%. Classified in HTS 7224.90.0075 as other alloy steel semi-finished products, as it does not match specific tool or razor blade steel definitions despite high chromium.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily stainless steel per Chapter 72 notes
Stainless steels with >=10.5% chromium fall under heading 7222 for stainless semi-finished products.
If carbon steel without alloying elements
Non-alloy steel ingots or billets if lacking specified alloy percentages.
If heat-resisting steel
Qualifies under U.S. note (g) if <0.3% carbon and 4-10.5% chromium.

Import Tips & Compliance
• Certify non-tool steel status with composition data; label with heat number for traceability; avoid misdeclaration as Chapter 72 stainless semi-finished (7222) without proper alloy verification
