HS code for Rigid plastic pipe: 3917.29
Plastics, tubes, pipes and hoses thereof, rigid, of plastics n.e.c. in heading no. 3917.
Classification of rigid plastic pipe under HS 3917.29
Rigid plastic pipes made from materials other than polyethylene, polypropylene, or polyvinyl chloride are classified under HS code 3917.29. Chapter 39 covers plastics, and heading 3917 is specifically for tubes, pipes, and hoses, and fittings therefor. The subheading 3917.2 is reserved for rigid tubes and pipes. While 3917.21, 3917.22, and 3917.23 cover pipes made of ethylene, propylene, and vinyl chloride respectively, 3917.29 serves as the residual category for rigid pipes made from different plastic polymers such as ABS, acrylic, or nylon. To qualify for this code, the pipe must maintain its shape and not be easily deformed, distinguishing it from flexible tubing found in 3917.3x. According to Chapter 39 notes, "tubes, pipes and hoses" means hollow products, whether semi-manufactures or finished products, of a kind generally used for conveying, conducting or distributing gases or liquids. The classification is driven by the material composition and the physical state of rigidity, which is defined as being unable to be bent by hand at room temperature without fracturing.

Codes often confused with 3917.29
Common mistake. Rigid pipes are often misclassified into material-specific codes like 3917.21 (Polyethylene), 3917.22 (Polypropylene), or 3917.23 (PVC). If the pipe is flexible or can be coiled, it should be classified under 3917.31 or 3917.39. Furthermore, if the pipe is fitted with joints or accessories, it might still fall under 3917, but the specific subheading may change depending on the assembly.
Top exporters and importers of HS 391729 (the code used for rigid plastic pipe), 2025
In 2025, the largest exporter of HS 391729 (the code used for rigid plastic pipe) in UN Comtrade data was Germany, with 13% of world exports; the largest importer in UN Comtrade data was the United States, with 8.9% of world imports.

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).
