The Authority ruled that the Fan Drive Assembly is classifiable as a fluid coupling under HSN 8483.60 rather than a general vehicle part. Consequently, the product is subject to a GST rate of 18% under Schedule III, as specific technical descriptions in the tariff take precedence over general end-use classifications.

M/s BorgWarner Cooling Systems (India) Private Limited, a manufacturer in Tamil Nadu, requested a ruling regarding their “Fan Drive Assembly”, which is used to cool engines in vehicles like trucks and tractors. This device acts as a clutch using silicone fluid and temperature sensors to control fan speed, helping the engine stay at the right temperature.
Although the company originally classified the product as a general vehicle part under HSN 8708 with a 28% tax rate, they applied to change it to HSN 8483. They argued that because the assembly is technically a fluid coupling device, it should be classified by its specific mechanical function rather than just being called a vehicle part, which would lower their GST rate to 18%.
Issues Involve in this Case
1. Is the Fan Drive Assembly classifiable under Heading 8483.60 (Clutch and Shaft Coupling) for GST purposes? If yes, is it covered under Sl. No. 369A of Schedule III of Notification No. 1/2017-Central Tax (Rate), attracting a 9% CGST rate?
2. Are individual parts and components of the assembly, when purchased separately, also classifiable under Heading 8483.60?
Decision of the AAR Tamilnadu
The Authority ruled in favour of BorgWarner by deciding that the Fan Drive Assembly should be classified based on its specific technical function rather than its general use in a vehicle. Under the law, a specific description like “fluid coupling” (HSN 8483) takes priority over a broad category like “vehicle parts” (HSN 8708), especially since this device uses fluid dynamics instead of mechanical friction to work.
Additionally, tax rules specifically exclude items in the 8483 category from being labelled as vehicle parts when they are an integral part of an engine. Because of this, the Authority held that the assembly qualifies for a lower GST rate of 18% (9% CGST and 9% SGST) under Schedule III. For any individual components of the assembly bought separately, they are classified under the “Other” category of HSN 8483.60.90 because there isn’t a more specific heading for those individual parts.
