U.S. imports of Metal-Reinforced Vulcanized Rubber Tubes, Pipes & Hoses Without Fittings (HS 400921) totaled $25.9M in August 2026, imported from 45 countries.
Importers of Metal-Reinforced Vulcanized Rubber Tubes, Pipes & Hoses Without Fittings paid $2.9M in duties in August 2026, an average duty rate of 11.17% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataMetal-reinforced rubber hose without end fittings — where steel wire braid, spiral wire, or metal helix is embedded in or wrapped around the rubber wall — is a primary component in hydraulic systems, high-pressure industrial fluid transfer, and oil-field applications. The metal reinforcement layer is what distinguishes this heading from unreinforced hose and from textile-reinforced hose, and CBP expects the construction to be documented (wire type, number of braid layers, working pressure rating) in the entry package. All imports under 4009210000 fall into a single US tariff line, but Section 301 tariffs may apply depending on origin, which is particularly relevant given that hydraulic hose manufacturing is concentrated in certain countries subject to those measures. Importers sourcing metal-reinforced hose should verify whether any applicable Section 301 exclusions cover their specific product.

CBP has generally treated an embedded metal helix or spiral that provides structural support — even if its primary purpose is kink or collapse resistance rather than pressure containment — as metal reinforcement, placing the hose under 400921. However, if the metal element is purely external and not combined with the rubber wall, classification may differ. A binding ruling is advisable for novel constructions.
The base MFN duty rate structure differs between the without-fittings and with-fittings lines under heading 4009. Beyond duty, the practical import consideration is that hose sold in bulk lengths without fittings is typically classified at entry as a semi-finished product, while hose assemblies with fittings may trigger additional product-safety or end-use documentation requirements depending on the application.
