HS Code 3917.23 – Plastics; tubes, pipes and hoses thereof, rigid, of polymers of vinyl chloride
HS code 3917.23 is the 6-digit subheading for plastics, tubes, pipes and hoses thereof, rigid, of polymers of vinyl chloride. It is used for UPVC water supply pipes, PVC sewage pipes, PVC electrical conduit, PVC drainage pipes and PVC well casings.
What HS 3917.23 covers
This HS code covers rigid tubes, pipes, and hoses made from vinyl chloride polymers, primarily unplasticized polyvinyl chloride (UPVC or PVC-U). These products are ubiquitous in construction and infrastructure due to their cost-effectiveness, excellent corrosion resistance, and ease of installation. Importers are typically construction companies, municipal water and sewage authorities, and agricultural sectors for irrigation. Exporters are large-scale PVC pipe manufacturers. The global trade in these pipes is substantial, driven by urbanization, sanitation projects, and agricultural needs. Key considerations include pressure ratings, diameter, wall thickness, and suitability for specific applications like potable water, sewage, or electrical conduit. PVC pipes have largely replaced traditional materials like cast iron or concrete in many applications due to their durability, lower maintenance, and environmental benefits over their lifecycle.

Top exporters and importers of HS code 391723, 2025
In 2025, the largest exporter of HS code 391723 in UN Comtrade data was China, with 15% of world exports; the largest importer in UN Comtrade data was the United States, with 10% 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).
