Standard International Trade Classification
U.S. imports of Cast Articles of Nonmalleable Cast Iron, Not Elsewhere Specified (SITC 69962) totaled $14.0M in August 2026, imported from 40 countries.
Importers of Cast Articles of Nonmalleable Cast Iron, Not Elsewhere Specified paid $3.9M in duties in August 2026, an average duty rate of 27.94% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataNonmalleable (gray) cast iron articles classified here are residual manufactures — finished or semi-finished castings that do not fit more specific headings for pipes, fittings, valves, or machinery parts. Gray cast iron's brittleness and excellent compressive strength make it a preferred material for counterweights, ballast blocks, machine bases, and certain architectural elements. Because this is a catch-all heading, classification disputes are common when a casting could plausibly be described as a part of a specific machine or structure; the essential character and primary function of the article are the deciding factors. Section 232 tariffs on steel and iron products may apply, and importers should confirm whether the casting's iron content and form trigger the measure.

A casting classifies here only when it cannot be more specifically described by another heading — for example, as a pipe fitting, valve body, or part of a named machine. If the casting is identifiable as a component of a specific apparatus or structure, it is generally classified with that apparatus. The NES heading captures truly general-purpose or unspecified castings.
A mill certificate or material test report specifying the iron alloy composition — particularly confirming the absence of the annealing treatment that would render it malleable — is the standard supporting document. Chemical composition data showing carbon content and microstructure type (flake graphite for gray iron) helps customs officers confirm the nonmalleable designation.
