Last updated: August 2026 dataRectangular (non-square) cross-section semifinished stainless steel — hot-worked slabs and similar intermediate shapes — feeds downstream flat-rolling mills that produce sheet, strip, and plate. The US schedule subdivides this heading by the ratio of width to thickness and by cross-sectional area, with lines 7218910015, 7218910030, and 7218910060 capturing progressively wider or larger-area rectangles; these dimensional thresholds matter for both classification and mill-order specifications. All entries under this heading remain subject to Section 232 tariffs, and the United Kingdom and Canada are the leading sources, with China also a notable supplier.

The US tariff lines under 7218910000 split rectangular semifinished products based on whether the width is less than four times the thickness (lines 7218910015 and 7218910030, further divided at 232 cm² cross-sectional area) or at least four times the thickness (7218910060). Measuring both dimensions accurately before entry is essential to avoid misclassification between these lines.
Once a rectangular intermediate has been hot-rolled to a width of 600 mm or more and reduced to a defined thickness range, it typically classifies as a flat-rolled product under heading 7219. The key test is whether the product has been worked to the point where it meets the dimensional and surface criteria for flat-rolled products; a slab that has only been rough-rolled but not brought to finished flat-rolled dimensions remains in 7218.
