Last updated: September 2026 dataThe residual 'not elsewhere specified or included' category for wide flat-rolled non-stainless alloy steel captures surface-treated, painted, clad, and otherwise finished products that do not fall under the zinc-coating or silicon electrical steel headings. Three 10-digit lines — 7225990002, 7225990010, and 7225990090 — separate high-nickel alloy steel from other alloy grades, reflecting the distinct metallurgical and end-use profiles of nickel-bearing flat products used in chemical processing and aerospace. The United Kingdom and Netherlands lead US supply, with Canada, Germany, and South Korea also prominent. Section 232 tariffs apply, and the breadth of this residual heading means classification disputes are relatively common; importers should document alloy composition and surface treatment thoroughly.

Coatings other than zinc — such as aluminum, paint, lacquer, plastic, or clad metal layers — as well as products that are polished, pickled, or otherwise finished without a zinc coating, typically fall into the 722599 residual heading. The specific surface treatment must be identified in the entry documentation, as different finishes can trigger different antidumping scope considerations.
Stainless steel is defined under the HTS by chromium content (generally 1.2% or less carbon and 10.5% or more chromium), not nickel content alone. High-nickel alloy steels that do not meet the chromium threshold for stainless classification fall under the alloy steel headings, including 7225990010 for high-nickel grades. Mill certifications showing full chemical composition are essential to defend the classification if challenged.
