Guidance on GST Compliance and Document Requirements for Trade Show Participation - Goods and Services Tax - GST

Dear Experts, My company is planning to participate in a Trade Show at an event in X City, State of Maharashtra, on May 15th and 16th, 2025, and we need to transfer some finished goods and assets from my head office in Y City, State of Tamil Nadu, to the event. I do not have any retail outlets in X City, but I have a retail outlet only in Z City of Maharashtra. Requesting you to provide guidance on the following: GST Compliance : What are the necessary GST procedures for transferring goods across state borders for a Trade Show? Do I need to take CTP Registration or any other specific tax documentation since I do not have a retail outlet in X City? Are there any exemptions or special rules for participating in trade shows that I should be aware of? Documents for Transport : What documents should accompany the goods during transit? Do I need an E-way Bill for inter-state movement, or is there a specific delivery challan or other documents required for transporting goods for a Trade Show? Are there any other documentation requirements that would be specific to the event or the transport of goods to a location where I don t have an established presence? Additional Procedures : Are there any other regulatory procedures I should be aware of when moving goods for an event in a state where I don t have a permanent retail presence? Sales at the Trade Show : In case there is a sale initiated at the fair or after the fair, should there be a separate GST return filed for this, or is it sufficient to disclose it in the GSTR-1 ?
