Importers of Flexible Plastic Tubes, Pipes & Hoses, Not Reinforced, Without Fittings paid $4.3M in duties in August 2026, an average duty rate of 9.41% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataUnreinforced flexible plastic tubing without end fittings is among the most broadly used fluid-conveyance forms across agriculture, food processing, medical devices, and general industry, making precise material identification essential for correct classification. The US schedule subdivides this heading by resin: PVC (3917320010), polyethylene (3917320020), and other plastics (3917320050), with a legacy residual line (3917320000) also present. Mexico and Canada together dominate US supply, reflecting deep USMCA-integrated plastics manufacturing, while China is also a significant source subject to potential Section 301 considerations. Because certain flexible tubing grades contact food or pharmaceutical products, FDA food-contact or drug-contact compliance documentation may be required alongside standard customs entry.

The distinction is straightforward: 391732 covers flexible, unreinforced plastic tubes and hoses presented without fittings attached, while 391733 covers the same type of hose presented with fittings. If fittings are attached at the time of importation — even if they could be removed — the article classifies under 391733. Importers sometimes strip fittings before shipment to manage duty exposure, but CBP may consider the commercial reality of the transaction.
Tubing intended for direct food or drug contact may require FDA review under food-contact substance regulations or drug-contact material standards, in addition to standard HTS classification. Importers should obtain the manufacturer's FDA compliance documentation (such as a food-contact notification or extractables/leachables data) before entry. Consult a licensed customs broker or regulatory counsel to confirm the specific admissibility requirements for your product.
