Product classification

HS code for PP pipe: 3917.22

Plastics, tubes, pipes and hoses thereof, rigid, of polymers of propylene.

Classification of PP pipe under HS 3917.22

Polypropylene (PP) pipes are classified under HS code 3917.22. Heading 3917 covers tubes, pipes, and hoses, and fittings therefor (for example, joints, elbows, flanges), of plastics. Subheading 3917.22 is specific to rigid tubes, pipes, and hoses made of polymers of propylene. To qualify for this classification, the product must meet the definition of \"rigid.\" In the context of Chapter 39, pipes are considered rigid if they cannot be bent at room temperature without being damaged or broken. These pipes are widely used in plumbing (PPR pipes), industrial chemical transport, and drainage systems due to their chemical resistance and thermal stability. The classification is determined by GRI 1, focusing on the material (propylene polymer) and the physical form (rigid tube/pipe).

Codes often confused with 3917.22

Common mistake. A common error is classifying PP pipes under 3917.32, which is for flexible tubes and pipes. If a pipe has a minimum bend radius that allows it to be coiled, it may be considered flexible. Another misclassification is 3917.21, which is reserved for pipes made of polymers of ethylene (PE). While PE and PP pipes are used in similar applications, the chemical polymer must match the code. Additionally, if the pipe has fittings already attached in a way that makes it a specific identifiable part of a machine, it might be classified under the machinery headings of Chapter 84 or 85, though this is rare for standard plumbing pipes.

Top exporters and importers of HS 391722 (the code used for PP pipe), 2025

In 2025, the largest exporter of HS 391722 (the code used for PP 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).

Questions about PP pipe

What is the HS code for PP pipe?

The HS code for PP pipe is 391722 (Plastics; tubes, pipes and hoses thereof, rigid, of polymers of propylene). The HS code for rigid polypropylene pipes is 3917.22.

How do I classify PP pipe for customs?

PP pipe is classified under HS code 391722 — Plastics; tubes, pipes and hoses thereof, rigid, of polymers of propylene. This is a 6-digit subheading level code.

Does 3917.22 include pipe fittings?

No, pipe fittings made of polypropylene, such as elbows or couplings, are classified under HS code 3917.40, even if they are made of the same material as the pipes.

Which countries are the top exporters of PP pipe (HS 391722)?

In 2025, the top exporters of HS 391722 (the code used for PP pipe) in UN Comtrade data were Germany ($195M, 15% of world exports), China ($140M) and Türkiye ($127M). World exports came to about $1.3B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

Which countries are the top importers of PP pipe (HS 391722)?
