HDPE Pipe HSN Code: Classification for Water, Plumbing, and Drainage Pipes
HDPE pipes are widely used for water supply, plumbing, drainage, and irrigation. Under GST, they are treated as plastic pipes, so the correct HDPE pipe HSN code is needed.
What is the HSN code for HDPE water pipes?
Pipes and hoses of plastics, including HDPE pipes, usually fall under heading 3917. This heading covers tubes, pipes, and hoses of plastics including polyethylene (PE), PVC, and other polymers.
Sample HSN and GST Rate Table for HDPE Pipes
| HSN Code | Product Name | Product Description | Usual GST Rate* |
|---|---|---|---|
| 3917 | HDPE pipes | Pipes and tubes of polyethylene for water, etc. | 18% |
| 3917 21 | Pipes of polymers | Pipes of polymers like polyethylene | 18% |
*Rates are indicative.
Are HDPE drainage pipes classified differently under HSN?
Drainage, sewerage, and irrigation pipes made from HDPE are still plastic pipes, so they also fall under 3917. The main use does not move them to a new chapter.
How HDPE water pipes are classified under HSN?
- Identify main material as polyethylene or similar plastic
- Confirm that pipe is rigid or flexible tube type
- Use heading 3917 with proper sub code
GST and HDPE pipe products
Most HDPE pipes attract 18 percent GST. Some projects for drinking water or irrigation may enjoy special rate under specific notifications, but that is linked to supply to government or project type.
