Teflon Tape HSN Code: Understanding HSN Classifications for Teflon Tapes
Teflon tape is a common plumbing item used to seal threaded joints in water lines, gas lines and other pipe fittings. Many hardware shops and sanitary stores sell it in small rolls to plumbers and households.
To use the Teflon tape HSN code correctly and charge GST without mistakes, traders and plumbing material dealers need to understand how Teflon tapes are classified under HSN and which GST rates normally apply after the changes from 22 September 2025.
What Is the Teflon Tape HSN Code?
Under GST, Teflon tape is usually treated as a plastic product because it is made from PTFE which is a type of plastic. In practice, many dealers classify Teflon tape in the plastics chapter along with other plastic sheets, strips and sealing tapes used in plumbing and industrial work.
There is no single line in the tariff that uses the words Teflon tape in the description, so businesses select the closest plastic HSN family based on the form of the product. PTFE thread seal tape is a thin strip or film of plastic supplied in rolls and used as a sealing material on pipe threads.
For day to day billing, most shops keep one standard Teflon tape item in their accounting software and map it to a common plastic HSN family. Related items like PVC insulation tape for cables can be mapped to the same or a nearby tape HSN family, while bigger plastic parts are linked to their own plastic HSN codes.
Key Teflon Tape HSN Codes and GST Rates after 22 September 2025
| HSN Code | Product Description | Product Type or Variant | GST Rate |
|---|---|---|---|
| 3920 | Plates, sheets, film and strip of plastics | PTFE thread seal tape supplied in rolls | 18% |
| 3919 | Self adhesive plates, sheets, film and strip of plastics | Self adhesive PTFE or plastic sealing tapes | 18% |
| 3926 | Other articles of plastics | Small plastic sealing accessories used with pipes | 18% |
| 7307 | Tube or pipe fittings of iron or steel | Pipe fittings where Teflon tape is applied on threads | 18% |
| 3917 | Tubes, pipes and hoses of plastics | Plastic plumbing pipes where Teflon tape is used on joints | 18% |
HSN Code for Teflon Tape and GST Rates
Teflon tape rolls that plumbers use on threaded joints are typically classified in the plastics chapter as strips or film of plastic used for sealing. Many suppliers map them to a general plastic sheet or strip HSN family such as 3920 and apply the standard GST slab for plastics.
If the Teflon tape has a clear self adhesive layer, some traders prefer to use the self adhesive plastic sheet and tape heading such as 3919. The basic nature of the product remains a plastic sealing tape used on threads in plumbing and gas work.
In both cases, the GST rate after 22 September 2025 is generally 18% for these plastic tape items. This keeps Teflon tape in line with other plastic goods such as pipes that are covered under the pipe HSN code and MS pipe HSN code.
Hardware shops that stock Teflon tape along with valves, taps and other small items often map it in the same group as other plastic accessories and hardware under the hardware HSN code. This makes billing, reporting and purchase matching easier across all fast moving hardware items.
GST on Teflon Tape and HSN Code Classification
Under the three slab GST structure that applies from 22 September 2025, Teflon tape is treated as a standard plastic and hardware product. It is not an essential food item and it is not a sin or luxury product, so it normally falls in the 18% GST slab under its plastic HSN family.
This means that when a trader sells Teflon tape as part of a plumbing bill or as a stand alone item, GST is usually charged at 18% on the sale value. The invoice shows the chosen plastic HSN code along with the description such as PTFE Teflon tape and the GST amount.
For correct input tax credit, contractors and maintenance firms that buy Teflon tape for use at sites must ensure that their suppliers mention the proper HSN code and GST rate on the invoice. When they also buy pipes, cables and other items covered under the cable HSN code the matching of HSN wise supplies in returns becomes smoother.
If there is any doubt between two possible plastic HSN families, businesses should choose the one that best describes the material and form of the Teflon tape and then use that family consistently in their accounting software and GST returns. The GST rate may vary depending on specific notifications and conditions but in most cases it remains in the 18% slab.
Conclusion
The Teflon tape HSN code is selected from the plastics chapter based on the fact that PTFE thread seal tape is a thin plastic strip or film supplied in rolls for sealing threads. Most traders place it in a general plastic sheet or tape HSN family and apply the standard GST rate for such plastic products.
By mapping every Teflon tape item to a suitable plastic HSN family and charging GST at 18% in invoices and returns, hardware shops and plumbing material dealers can keep their billing clear, support smooth input tax credit for customers and reduce the risk of GST classification disputes linked to sealing tapes and plumbing accessories.
