About HS Code 391733

This category encompasses plastic tubes, pipes, and hoses that are not reinforced or combined with other materials, but are supplied *with fittings*. This signifies a more complete, ready-to-install product, adding value through pre-assembly or integrated connection points. These items are widely used in plumbing, HVAC, automotive, and industrial fluid handling systems where ease of installation and system integrity are paramount. Importers typically include construction contractors, automotive manufacturers, and specialized distributors seeking complete solutions. The trade in these goods reflects a demand for efficient, labor-saving components in various assembly processes.

Products Under This Code

Pre-assembled PEX plumbing lines, PVC drain assemblies with glued fittings, HDPE irrigation systems with integrated connectors, flexible conduit kits with connectors, pneumatic tubing with quick-connect fittings, garden hoses with attached connectors

Real World Examples

SharkBite PEX fittings on PEX tubing, PVC DWV pipe with solvent-welded couplings, garden hose with attached brass connectors, pneumatic air lines with push-to-connect fittings

Common Misclassification

Often confused with 391732 (without fittings) or 391740 (fittings only). The distinction is the combination of tube/pipe and fittings.
