Oil Seal HSN Code for GST Filing
Oil seals are important spare parts used in engines, gearboxes, pumps and industrial machines to stop oil leakage and protect moving parts. They are common in the automotive sector as well as in factories, farms and workshops.
To use the oil seal HSN code correctly and apply the right GST rate, traders, spare parts dealers and manufacturers need to understand how oil seals are classified under GST and how the three slab structure of 5%, 18% and 40% after 22 September 2025 generally applies to these products.
What is the HSN Code for Oil Seals Used in Various Industries?
Under GST, oil seals are generally grouped in the family that covers gaskets and similar joints of metal combined with other materials. This family also covers mechanical seals and sealing sets that are used to prevent leakage of oil, grease and other fluids in machines.
Standard rotary shaft oil seals, automotive oil seals and many industrial oil seals are usually treated as part of this same family as long as they match the description and are used as mechanical sealing elements rather than as simple rubber rings.
Key Oil Seal HSN Codes and GST Rates after 22 September 2025
| HSN Code | Product Description | Product Type or Variant | GST Rate |
|---|---|---|---|
| 8484 | Oil seals and sealing sets | General purpose oil seals and sealing sets for machines | 18% |
| 8484 | Automotive oil seals | Oil seals for engines, gearboxes and axles in vehicles | 18% |
| 8484 | Industrial oil seals | Oil seals used in pumps, compressors and industrial machinery | 18% |
How Does GST Apply to Oil Seals Under HSN Code?
In the present three slab GST structure, oil seals that fall under the mechanical seals and gaskets family are usually treated as standard taxable goods. For most regular trade, they attract the 18% slab as general industrial and automotive components.
The GST rate may vary depending on specific notifications and conditions, but there is no separate luxury or sin treatment for normal oil seals. When setting up items in accounting software, dealers normally link all oil seal products in this family with the 18% rate so that invoices and tax reports remain consistent.
Why is it Crucial to Use the Correct HSN Code for Oil Seals in GST?
Using the correct HSN code for oil seals is important because it shows clearly how the item has been classified and why a particular GST rate has been charged. This helps workshops, factories and transporters claim input tax credit smoothly on the spare parts they buy.
If oil seals are wrongly shown under a different HSN family or with an incorrect GST rate, it can cause mismatch between sales and purchase data. This may lead to notices, interest or penalties if the tax paid is lower than what is due for that family of goods.
Once the correct oil seal HSN family and GST rate are saved in the item master, every invoice carries the same classification. This keeps GSTR one data clean and makes future review or audit much easier for both the supplier and the buyer.
How Do Different Types of Oil Seals Get Classified for GST?
Different oil seals such as rotary shaft seals, wheel hub seals, engine crankshaft seals and pump seals can all fall under the same sealing family when they are designed as mechanical oil seals and match the tariff description.
In practice, businesses create separate stock items for each size, brand or application, for example oil seals for cars, tractors or industrial pumps. Even then, these items usually share the same oil seal HSN family and GST rate, while the exact use is captured in the item name and description.
Only when a product does not behave like a mechanical oil seal, or is better described as a different kind of component, should a different HSN family be considered. In doubtful situations, it is safer to review the detailed description and use neutral wording rather than guess a new classification.
Conclusion
Oil seal HSN codes usually place oil seals in the family for mechanical seals, gaskets and similar joints that stop fluid leakage in engines and machines. Under the present three slab GST structure, these products are normally treated as standard industrial and automotive parts that attract 18% GST.
By mapping every oil seal item to the correct HSN family, linking it with the proper GST slab and using the same details on all invoices, traders and spare parts dealers can raise accurate bills, support input tax credit for buyers and reduce the risk of classification disputes in GST.

Frequently Asked Questions
-
What is the HSN code for oil seals?
Oil seals are generally classified in the family for mechanical seals, gaskets and similar joints that combine metal with other materials. This family covers oil seals used in engines, gearboxes, pumps and other machines.
-
Are there different HSN codes for oil seals based on material type?
Most rubber bonded and metal cased oil seals share the same mechanical sealing family as long as they work as oil seals. A different HSN family may apply only if the item no longer fits the description of a mechanical seal or gasket.
-
How is the GST rate applied to oil seals in GST returns?
For regular trade, oil seals in this family are generally taxed at 18% as standard industrial parts. Once this rate is set in the item master, the same rate flows to all invoices and is reflected in the HSN wise summary in GSTR one.
-
What is the classification for oil seals in the automotive industry?
Automotive oil seals for engines, gearboxes and wheel hubs are usually grouped in the same mechanical sealing family as other oil seals. Their use in vehicles is captured in the item description, while the HSN family remains the same.
-
How do I ensure proper HSN code classification for oil seals under GST?
Check that the product is a true mechanical oil seal, match it with the sealing family description and set that HSN code and the 18% rate in your accounting software. Use the same code and rate on all invoices so that your GST returns stay consistent.
