HS Code 3917.32 – Plastics; tubes, pipes and hoses thereof, other than those of item no. 3917.31, not reinforced or otherwise combined with other materials, without fittings
HS code 3917.32 is the 6-digit subheading for plastics, tubes, pipes and hoses thereof, other than those of item no. 3917.31, not reinforced or otherwise combined with other materials, without fittings. It is used for PVC drainage pipes, PEX tubing, HDPE water supply pipes, PP chemical transfer hoses and flexible conduit for electrical wiring.
What HS 3917.32 covers
This HS code covers plastic tubes, pipes, and hoses that are not reinforced or combined with other materials, and are supplied without fittings. These products are fundamental components across numerous industries, primarily for fluid and gas transfer. Key materials include PVC, polyethylene (PE), and polypropylene (PP), chosen for their corrosion resistance, flexibility, and cost-effectiveness. Major importers and exporters include manufacturers of plumbing systems, irrigation equipment, industrial machinery, and construction companies. Trade in these goods is driven by infrastructure development, agricultural needs, and industrial expansion globally. Understanding the specific polymer type and intended application is crucial for accurate classification and market analysis.

Codes often confused with 3917.32
Common mistake. This code is often confused with 391733 (with fittings) or 39172X (reinforced/combined). The key differentiator is being 'not reinforced' and 'without fittings'.
Top exporters and importers of HS code 391732, 2025
In 2025, the largest exporter of HS code 391732 in UN Comtrade data was the United States, with 22% of world exports; the largest importer in UN Comtrade data was Mexico, with 13% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
