Last updated: July 2026 dataBase metal flexible tubing — whether of steel, copper, aluminum, or other base metals — serves critical roles in hydraulic systems, HVAC installations, and industrial fluid conveyance, where rigid piping is impractical. Classification hinges on the specific base metal composition and whether fittings are attached, as these factors can shift the applicable HTS heading. Imports of steel-based flexible tubing may be subject to Section 232 tariffs, making origin documentation and mill certificates essential for accurate duty assessment. Buyers should confirm whether fittings are integral or separately classified, as that distinction affects both duty rate and admissibility.

It can. When fittings are permanently attached and integral to the assembly, the product may still classify under the flexible tubing heading, but customs authorities may scrutinize whether the fittings constitute the essential character of the article. Importers should document the tubing's primary function and the nature of any attached fittings to support their classification position.
Steel-based flexible tubing can fall within the scope of Section 232 tariffs on steel articles, depending on the steel content and product form. Importers should review the specific product composition and consult a licensed customs broker to determine whether an exclusion applies or whether the Section 232 measure is triggered.
