The short version
- Power Build Private Limited asked for the correct HSN code for geared motors.
- The product is an assembly of an electric motor and a gear box.
- The authority ruled the assembly falls under HSN code 8501.
- This classification applies the GST rate for electric motors to the entire unit.
In short
The company asked the Gujarat Authority for Advance Ruling (GAAR) to decide the correct Harmonized System of Nomenclature (HSN) code for a 'geared motor'. Because the product combines a motor and a gear box, there was confusion over whether it should be taxed as a motor or as a mechanical gear part. The authority decided that the entire assembly is treated as an electric motor for GST purposes.
What has changed
How it worked before
Businesses were uncertain whether to classify geared motors under the code for gear boxes (8483) or electric motors (8501), as the two components often carry different tax rates.
What has changed
The authority clarified that under international HSN guidelines, motors remain classified as motors even when attached to gears. This means manufacturers should apply the GST rate for electric motors to the entire geared motor assembly.
Who this affects
Manufacturers and suppliers of integrated electrical and mechanical assemblies like geared motors.
An example
Imagine a company called 'Precision Drives' that also makes geared motors. They were previously unsure if they should split the tax rate between the motor and the gear box. Based on this ruling, they can now confidently classify the entire unit under HSN 8501 and apply the corresponding GST rate for electric motors.
What you should do
If you manufacture similar products, you can use this logic to support your classification. However, remember that an advance ruling only legally binds the company that asked for it and their specific tax officer. You should consult with your tax advisor to see if this interpretation applies to your specific product configuration.
If you do nothing
If you classify your goods under the wrong HSN code, you risk paying the incorrect amount of GST. If a tax officer disagrees with your classification during an audit, you may be required to pay the difference in tax plus interest and potential penalties. Relying on a ruling that does not apply to you can lead to costly disputes.

Questions before the authority
- What is the HSN Code and GST Tax Rate of a product ‘Geared Motor’?
Facts
The applicant manufactures and supplies 'Geared Motors', which are assemblies consisting of an Electric Motor coupled with a Gear Box. The applicant sought a ruling on the correct classification and GST rate for this assembly, noting that the individual components fall under different HSN codes and tax rates. The applicant contended that the product should be classified under the HSN code for Electric Motors.
Ruling
| Question | What the authority ruled |
|---|---|
| Geared Motor | Chapter Heading 8501 Taxed at the rate applicable to Electric Motors |
The Authority ruled that the product 'Geared Motor' is classifiable under Chapter Heading 8501 of the Customs Tariff Act, 1975. Consequently, the GST rate applicable to Chapter Heading 8501 applies to the product.
Reasoning
The Authority relied on the Explanatory Notes of the Harmonized System of Nomenclature (HSN) for Tariff Headings 8483 and 8501. The notes for Heading 8483 explicitly state that it does not cover gear boxes combined with a motor, while the notes for Heading 8501 specify that motors remain classified there even when equipped with gears or gear boxes. Therefore, the assembly is **appropriately classified under Heading 8501** as an electric motor. This interpretation aligns with the principle that HSN Explanatory Notes are a dependable guide for tariff classification.
Provisions relied on
- Section 97(2) of CGST / GGST Act, 2017
- Notification No. 1/2017-Central Tax (Rate) dated 28.06.2017
- Customs Tariff Act, 1975
- Harmonized System of Nomenclature (HSN) Explanatory Notes
For the practitioner
This ruling provides clarity for manufacturers of geared motors by confirming that the assembly is **classified under the motor's HSN code (8501)** rather than the gear box's code (8483). It settles the classification dispute by prioritizing the HSN Explanatory Notes over the individual components' classifications. Practitioners can use this to support the tax treatment of similar integrated electrical-mechanical assemblies.
