U.S. imports of plastic tubes, pipes & hoses, nesoi (HS 391739) totaled $67.2M in July 2026, traded with 73 countries.
Importers of Plastic Tubes, Pipes & Hoses, NESOI paid $9.4M in duties in July 2026 — an effective duty rate of 18% on $51.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataReinforced flexible plastic hose — including metal-reinforced hydraulic hose below the 27.6 MPa burst-pressure threshold and other composite constructions — falls into this residual heading when not captured by more specific provisions. The US schedule distinguishes metal-reinforced flexible hose (3917390010), non-metal-reinforced flexible PVC hose (3917390020), other non-metal-reinforced flexible hose (3917390050), and a general residual line (3917390002). China and Taiwan together lead US supply, a concentration that means Section 301 tariff exposure is a live cost consideration for most importers in this heading. Correct classification requires careful analysis of reinforcement type and material, as the boundary with heading 391731 (high-pressure hose) and heading 391732 (unreinforced hose) is frequently contested.

Heading 391731 applies specifically to flexible plastic hose with a minimum burst pressure of 27.6 MPa, regardless of whether it is reinforced. If a metal-reinforced hose meets that burst-pressure threshold, it classifies under 391731. If it does not meet the threshold — even if it is metal-reinforced — it falls into the NESOI provisions of 391739. Burst-pressure test documentation is therefore the critical evidence for resolving this boundary.
Chinese-origin reinforced plastic hose is subject to Section 301 tariffs, which significantly increase landed costs compared to MFN rates alone. Taiwan-origin product is not subject to Section 301 measures, making it a common alternative source. Importers should verify the current Section 301 list status for the applicable 10-digit line and consider total landed cost — including duty, freight, and lead time — when evaluating supplier diversification.
