HS code for Plastic hose connector: 3917.40

Plastics, tube, pipe and hose fittings (e.g. joints, elbows, flanges).

Classification of plastic hose connector under HS 3917.40

Plastic hose connectors are classified under HS code 3917.40, which is the dedicated category for tube, pipe, and hose fittings made of plastic. This classification is based on the function of the article as a component designed to join sections of piping or to connect a hose to a source or an appliance. According to the General Rules of Interpretation, fittings are classified under the same heading as the tubes or pipes they are intended for, provided they are made of the same material. Heading 3917.40 includes a wide variety of shapes such as elbows, tees, unions, flanges, and couplings. These articles are typically manufactured through injection molding and may feature threads for mechanical connection. It is important to note that for a connector to stay in 3917.40, it must be a passive component. If the connector incorporates a mechanism to control the flow of liquid, such as a tap or a valve, the classification shifts to Chapter 84. The material must be predominantly plastic; metal-plastic hybrids are classified based on the material that provides the essential character, though most standard hose connectors are entirely polymer-based.

Codes often confused with 3917.40

Common mistake. The most common misclassification is under HS code 3926.90 (Other articles of plastics). While 3926 is a catch-all, 3917.40 is more specific for pipe and hose fittings and takes precedence. Another error involves HS code 8481.80; if the connector has an internal shut-off valve or a flow regulator, it is classified as a valve under 8481 rather than a fitting under 3917.

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).
