U.S. imports of grain-oriented silicon electrical steel, flat-rolled, under 600 mm wide (HS 722611) totaled $6.1M in April 2026, traded with 9 countries.
Last updated: April 2026 dataNarrow-format grain-oriented silicon electrical steel (GOES) — under 600 mm wide — is slit or produced to width for use in smaller transformer cores, distribution transformers, and specialty magnetic components. The US schedule provides four 10-digit lines (7226110000 through 7226119060) that distinguish widths between 300–600 mm from those under 300 mm, and further split the narrower band by thickness relative to 0.25 mm — a specification threshold that reflects the ultra-thin lamination grades used in high-efficiency transformer designs. Japan and Germany are the leading suppliers, with Mexico and Canada also significant. Section 232 tariffs apply, and importers should confirm that mill certifications specify both width and thickness to support the correct 10-digit classification.

Ultra-thin GOES laminations (0.25 mm or less) are used in high-frequency and high-efficiency transformer cores where minimizing eddy-current losses is critical. The US tariff schedule separates these from thicker laminations under separate 10-digit lines (7226119030 vs. 7226119060), so accurate thickness measurement — supported by mill test reports — is essential to avoid misclassification.
Mexico is a USMCA partner, and goods that meet USMCA rules of origin may qualify for preferential tariff treatment on the base MFN duty. However, Section 232 steel tariffs apply separately and are not waived by USMCA preference claims. Importers should evaluate both the origin qualification and the Section 232 exposure — including any available product exclusions — before relying on a duty estimate.
