17-4 PH Stainless Alloy Steel Round Bar
Precipitation-hardening 17-4 PH stainless alloy steel round bar, hot-rolled for aerospace fasteners and valves. Although containing 17% chromium, classified as 'other alloy steel' bar under 7228.60.60.00 when not cold-formed, distinguishing from basic stainless categories. Heat-treated condition H1150 standard.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as stainless steel bar
Standard stainless bars (heading 7222) if not treated as specialty alloy steel.
If ground or polished surface finish
Further worked surfaces (per chapter note) like grinding move to 7228.70.
If width exceeds bar dimensions for flat-rolled
Wide products may classify as flat-rolled in 7208 instead of bars.

Import Tips & Compliance
• PH grades may border stainless classification; provide detailed chemistry certs showing precipitation-hardening treatment
• Avoid rust/discoloration claims at entry per chapter note—no duty allowance for surface conditions
• Document as 'not cold-formed' explicitly in commercial invoice for smooth CBP processing

AISI 4140 Alloy Steel Round Bar
A hot-rolled round bar made from AISI 4140 chromium-molybdenum alloy steel, commonly used for shafts, gears, and axles in machinery. It falls under HTS 7228.60.60.00 as a non-cold-formed bar of other alloy steel, not meeting specific alloy steel definitions in chapter notes like tool steel or ball-bearing steel. The product is supplied in straight lengths without cold-forming processes.
