Other Forged or Stamped Iron or Steel Articles (NESOI, Not Further Worked)

'Not further worked' means the article has not undergone any significant secondary operation — such as machining, grinding, drilling, threading, or heat treatment — beyond the forging or stamping process itself. Once a forged blank is machined to final dimensions or drilled for assembly, it typically moves to a more specific heading that reflects its finished function (e.g., a flanged fitting, a mechanical part). Importers should assess the state of the article at the time of importation to determine whether it remains classifiable as a not-further-worked forging.

Forged articles (7326190010) are shaped by applying compressive force to heated or cold metal using dies, producing a wrought grain structure. Stamped articles (7326190080) are formed by pressing sheet or plate metal in a die without significant heating. The distinction matters because CBP may request manufacturing process documentation to confirm the correct line, and the two sub-lines may be subject to different statistical reporting or trade remedy scrutiny. Supplier process documentation should clearly identify the forming method.
