U.S. exports of Flexible Plastic Tubes, Pipes & Hoses with Minimum Burst Pressure of 27.6 MPa (HS 391731) totaled $14.6M in August 2026.
Importers of Flexible Plastic Tubes, Pipes & Hoses with Minimum Burst Pressure of 27.6 MPa paid $974K in duties in August 2026, an average duty rate of 10.33% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Flexible Plastic Tubes, Pipes & Hoses with Minimum Burst Pressure of 27.6 MPa imports of $9.5M in August 2026 ran 24% below the year-to-date monthly average of $12.5M.
Last updated: August 2026 dataThe 27.6 MPa (4,000 psi) minimum burst-pressure threshold is the defining technical criterion that separates high-pressure hydraulic hose from ordinary flexible plastic tubing, making this heading critical for fluid-power and heavy-equipment applications. All US imports enter on a single line (3917310000), and correct classification requires documented burst-pressure test data — a detail that customs examiners may request. France leads US supply under this heading, followed by Mexico and India, reflecting the concentration of hydraulic hose manufacturing among specialized industrial producers. Importers should verify whether their product meets the burst-pressure threshold through third-party testing, as misclassification into a lower-pressure heading can trigger penalty exposure.

Importers should retain manufacturer test reports or third-party laboratory certifications confirming that the hose meets or exceeds the 27.6 MPa minimum burst pressure per a recognized standard (such as SAE or ISO). CBP may request this documentation during examination or in a post-entry audit, and its absence can lead to reclassification into a lower-pressure flexible hose heading with potential duty and penalty implications.
No — when a flexible plastic hose meets the specific 27.6 MPa minimum burst-pressure criterion, heading 391731 takes precedence as the more specific provision. The NESOI headings (391739) apply only to flexible hoses that do not meet the burst-pressure threshold or are not otherwise more specifically described. Classification should always follow the most specific applicable heading.
