HS code for Plastic tubing with connectors: 3917.33
Plastics, tubes, pipes and hoses thereof, other than those of item no. 3917.31, not reinforced or otherwise combined with other materials, with fittings.
Classification of plastic tubing with connectors under HS 3917.33
Plastic tubing with connectors is classified under HS code 3917.33. Heading 3917 covers tubes, pipes, and hoses, and their fittings, of plastics. Subheading 3917.33 is designated for \"Other, not reinforced or otherwise combined with other materials, with fittings.\" To qualify for this code, the product must meet several criteria: it must be a tube, pipe, or hose as defined in Note 8 to Chapter 39 (hollow products used for moving gases or liquids); it must not be reinforced with metal, textile, or other materials; and it must be imported with fittings (such as joints, elbows, or flanges) already attached. The presence of \"fittings\" is the defining characteristic that separates this code from 3917.32. This classification is essential for ensuring that the assembly is treated as a single functional unit rather than separate components. The material can be any plastic polymer, such as PVC, PE, or PP, provided it is not reinforced. If the tubing is designed for high-pressure applications and has a burst pressure of 27.6 MPa or more, it would instead fall under 3917.31, even if it has fittings.

Codes often confused with 3917.33
Common mistake. The most frequent misclassification is 3917.32, which is for tubing without fittings. Another common error is 3917.40, which is for the fittings alone. If the tube is reinforced with a textile braid, it must be moved to 3917.39. Additionally, if the tube is rigid, it falls under 3917.21 through 3917.29.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
