Rough Forged Steel Slip-On Flange
Unprocessed forged flange of nonalloy steel that slips over pipe ends for welding, used in low-pressure applications like water systems. No machining after forging, meeting the raw state for this HTS. Falls under 7307.91.10.00 due to its iron/nonalloy steel construction and forging process.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If tooled for specific threading or finishing
Any post-forging processing moves it to 'machined' statistical suffixes.
If constructed from stainless steel
Stainless steel flanges have dedicated headings separate from iron/nonalloy.
If designed specifically as pump or compressor parts
End-use as machinery parts can reclassify under Chapter 84 functional components.

Import Tips & Compliance
• Provide forging process affidavits to confirm no post-forging treatment, preventing misclassification
• Label shipments clearly as 'unmachined forged flanges' to speed customs clearance
• Watch for alloy contamination in steel; test certificates avoid duties under wrong subheading
