Last updated: April 2026 dataDoors, windows, door thresholds, and window frames fabricated from iron or steel serve the commercial construction, industrial facility, and security-door markets, where steel's strength and fire-resistance ratings are the primary selection criteria over aluminum alternatives. Imports of these articles are subject to Section 232 tariffs on steel, and the fabricated nature of the goods does not automatically exempt them from coverage. Fire-rating certifications (UL listings), thermal performance data, and corrosion-protection specifications are commonly required by building codes and must be verified against the destination jurisdiction's requirements.

Steel doors used in fire-rated assemblies must carry a listing from a nationally recognized testing laboratory (NRTL) such as UL or Intertek, certifying compliance with NFPA 80 and the applicable fire-resistance rating (e.g., 20-minute, 45-minute, 90-minute). Foreign manufacturers must obtain this listing through testing at an accredited facility; the listing label must be affixed to the door before installation and is typically verified by the authority having jurisdiction (AHJ) during inspection.
A door slab alone and a pre-hung unit (slab plus frame, hinges, and hardware) may be classified differently depending on whether the complete assembly is presented as a set. Pre-hung units with all components imported together are often classified as a complete door assembly, while separately imported slabs and frames may each be classified under their own provision. Consulting a customs broker before structuring the shipment can prevent post-entry reclassification.
