About HS Code 721631

This HS code covers substantial U-shaped structural sections, also known as channels, made from iron or non-alloy steel. These profiles are produced via hot-rolling, hot-drawing, or extrusion, and are specifically characterized by a height of 80mm or more. They are fundamental in heavy construction, infrastructure projects, and the manufacturing of large machinery and vehicles, providing robust structural support and framing. Importers are typically large construction firms, infrastructure developers, and heavy equipment manufacturers. Exporters are major integrated steel mills globally. Trade in these products is characterized by high volume, adherence to international standards (e.g., ASTM, EN), and significant logistical considerations due to their size and weight, making them critical for large-scale engineering.

Products Under This Code

Large steel channels, hot-rolled U-beams, structural U-sections, heavy steel channels, C-beams, parallel flange channels, standard steel channels.

Real World Examples

Bridge components, building frames, truck chassis, railway car frames, heavy machinery bases, industrial platforms.

Common Misclassification

Often confused with smaller U-sections under 721610 if the height dimension (80mm or more) is not accurately measured. Also, I or H sections (721632, 721633) are distinct shapes.

EU Regulatory Requirements

This product falls under the Carbon Border Adjustment Mechanism (CBAM). Importers to the EU must declare embedded carbon emissions and purchase CBAM certificates.
