HS Code for PP pipe

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).

Products Included

• PPR (Polypropylene Random Copolymer) pipes for hot and cold water
• PP-H (Homopolymer) rigid industrial pipes
• PP-B (Block Copolymer) drainage pipes
• Rigid polypropylene conduit for electrical cables
• High-temperature resistant PP pressure pipes

Common Misclassification

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.

FAQ

What is the HS code for PP pipe?

The HS code for rigid polypropylene pipes is 3917.22.

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.
