E-commerce FDI rules: marketplace and B2B models allowed automatically while inventory-based e-commerce remains restricted. The amendment defines e-commerce entities and distinguishes inventory based and marketplace models for FDI purposes, permitting full FDI under the automatic route for B2B and marketplace models while prohibiting FDI in inventory based e-commerce. Marketplace platforms must not own inventory, may transact with registered sellers on a B2B basis, provide support services, disclose seller details, avoid influencing prices, and limit annual sales from a single vendor to twenty-five percent; sale of services online is automatic subject to sectoral conditions and applicable laws.
