In re BorgWarner Cooling Systems (India) Private Limited (GST AAR Tamilnadu)
In the automotive and engineering industry, the product in question is NOT referred to or understood as a conventional dry-plate or friction-based clutch. Instead, it is consistently identified as a due to its operational characteristics. This trade terminology distinguishes it from traditional clutches which operate through friction.
The Tamil Nadu Authority for Advance Ruling (AAR) in In re BorgWarner Cooling Systems (India) Private Limited examined the classification and applicable GST rate for “Fan Drive Assembly” used in engine cooling systems of motor vehicles. The applicant manufactures and supplies these assemblies for use in vehicles such as trucks, SUVs, and tractors. The product operates using a viscous fluid coupling mechanism, where silicone fluid regulates the engagement and disengagement of the radiator fan based on engine temperature, thereby improving fuel efficiency and maintaining optimal engine performance. Unlike traditional clutches, it does not rely on friction plates but functions through fluid dynamics.
The applicant had been classifying the product under HSN 8708 as parts of motor vehicles, attracting higher GST, but sought clarification on whether it should instead be classified under HSN 8483.60 as a “fluid coupling,” which would attract GST at 18%. The AAR analysed the product’s design, function, and operation, noting that it is a self-contained mechanical device that controls torque transmission through viscous fluid and not friction-based mechanisms. The Authority observed that conventional clutches under HSN 8708 involve mechanical engagement and disengagement through friction, whereas the applicant’s product operates on fluid coupling principles.
