The GST rate on transport to transport services depends on the type of transport service, the type of goods transported, and the type of customer. Here are some general guidelines based on the web search results:
If the service is provided by a goods transport agency (GTA), the GST rate is 5% (CGST 2.5% and SGST 2.5%) or IGST 5%, provided that the GTA does not take credit of input tax charged on goods and services used in supplying the service12. The GTA can also opt to pay GST at 12% (CGST 6% and SGST 6%) or IGST 12%, in which case it can take credit of input tax3.
If the service is provided by any other transporter, the GST rate is 12% (CGST 6% and SGST 6%) or IGST 12%, and the transporter can take credit of input tax3.
If the service is provided by a packer and mover, the GST rate is 18% (CGST 9% and SGST 9%) or IGST 18%, if the service includes packing, disassembling, loading, unloading, unpacking, transportation, and insurance4. If the service only includes transportation, the GST rate is 5% or 12%, as mentioned above4.
