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.
