Seller obligations changing from 1 January 2027
Summary
Under the amended e-commerce consumer protection rules, marketplace sellers must display government identification numbers and disclose origin, best-before dates and other details upfront. Platform duties also grow, so platforms will ask sellers for more data.
Key points
- Sellers: display identifiers such as GSTIN and MSME registration number (new)
- Platforms: label sponsored products, show the lowest price in the 30 days before a cut, put the seller's name on invoices in the same font size
- Annual dark pattern self-audit and certificate display (the 2025 advisory becomes mandatory)
