Last updated: May 2026 dataFlexible plastic hose assemblies — tubing presented with fittings already attached — serve as ready-to-install fluid-transfer components in automotive, HVAC, laboratory, and industrial applications, where the fitting type and connection standard often drive purchasing decisions as much as the hose material itself. All US imports enter on a single line (3917330000), and the presence of fittings at time of importation is the key classification trigger distinguishing this heading from the without-fittings provision. Singapore leads US supply under this heading, a notable concentration that reflects the island's role as a regional hub for precision fluid-handling component assembly. Importers should confirm that the fittings are permanently or semi-permanently attached, as loose fittings packed separately with hose may be classified as separate articles.

Singapore functions as a major regional manufacturing and logistics hub for precision fluid-handling components, with multinational manufacturers operating assembly facilities there to serve global markets. Its prominence in this heading reflects both direct production and the consolidation of components from across Southeast Asia into finished hose assemblies for export.
A hose assembly with plastic tubing and metal fittings can still classify under 391733 if the plastic tubing is the essential component and the fittings are accessories to it. However, if the metal fittings are substantial enough to give the article its essential character, or if the hose is reinforced with metal, classification may shift to 391739 or even a metal-goods heading. The specific construction and end-use should be reviewed carefully, and a CBP binding ruling is advisable for borderline cases.
