Last updated: August 2026 dataWide-flange H-sections of iron or nonalloy steel, hot-rolled to 80 mm or more in height, are subdivided at the 10-digit level by weight per unit length: under 11.3 kg/30.5 cm (7216330030), 11.3–27.2 kg/30.5 cm (7216330060), and all others (7216330090), with a legacy line (7216330000) also present. These weight-based subdivisions reflect the structural engineering significance of section weight in specifying beams for columns, piles, and heavy framing. South Korea is the leading US import source, with Luxembourg and the United Arab Emirates also significant suppliers. All imports are subject to Section 232 steel tariffs, and South Korean steel is subject to a quota arrangement rather than the tariff under the terms negotiated with the US.

The three active weight-based lines under 721633 use weight in kilograms per 30.5 cm (one foot) of length as the sorting criterion: 7216330030 covers sections weighing less than 11.3 kg/30.5 cm, 7216330060 covers 11.3 to 27.2 kg/30.5 cm, and 7216330090 covers heavier sections. The mill certificate or AISC section tables provide the pounds-per-foot (or kg/m) figure needed to convert and assign the correct line.
South Korea, the leading supplier of H-sections to the US, negotiated a quota-based arrangement with the United States in lieu of Section 232 tariffs. Korean-origin H-sections entering within the quota volume are exempt from the Section 232 tariff, but volumes above the quota threshold are subject to the tariff. Importers should monitor quota fill rates and filing windows, as the quota can be exhausted earlier in the calendar year for high-demand sections.
