Product classification
HS code for Polypropylene pipe: 3917.22
Plastics, tubes, pipes and hoses thereof, rigid, of polymers of propylene.
Classification of polypropylene pipe under HS 3917.22
Polypropylene pipe is classified under HS code 3917.22. This classification falls under Chapter 39, which covers plastics and articles thereof. Heading 3917 is dedicated to tubes, pipes, and hoses, and their fittings. The subheading 3917.22 specifically identifies rigid tubes and pipes made from polymers of propylene. To be classified here, the product must meet the definition of "tubes, pipes, and hoses" provided in Note 8 to Chapter 39, which includes hollow products, whether semi-manufactures or finished, of a kind generally used for conveying, conducting, or distributing gases or liquids. The term "rigid" is essential; it refers to products that cannot be bent at room temperature without breaking or being permanently damaged. This code is widely used for PPR (Polypropylene Random Copolymer) pipes used in hot and cold water plumbing systems and industrial chemical transport.

Codes often confused with 3917.22
Common mistake. Polypropylene pipes are often misclassified under 3917.32, which is for flexible tubes and pipes that have a minimum burst pressure of 27.6 MPa but are not reinforced. Another common error is using 3917.40, which is strictly for pipe fittings (such as elbows, joints, and flanges) rather than the pipes themselves. If the pipe is reinforced with metal or other materials, it may move to 3917.39. Additionally, if the pipe is not hollow, it would be classified as a rod or profile under 3916.90.
Top exporters and importers of HS 391722 (the code used for polypropylene pipe), 2025
In 2025, the largest exporter of HS 391722 (the code used for polypropylene pipe) in UN Comtrade data was Germany, with 15% of world exports; the largest importer in UN Comtrade data was the United States, with 7.4% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
