Now, small listed firms where trading has been less than 10 per cent of the total shares in the last 12 months can get delisted from the stock exchanges.
At present, Sebi norms allow only those companies whose shares have not been traded for the preceding one year to get delisted.
There are more than 1,000 small companies where trading has been negligible for several years.
The move comes after the board of Securities and Exchange Board of India (Sebi) approved the norms in November.
The relaxation is provided in case the "share capital of a particular class of shares of the company is not identical throughout such period, the weighted average of the shares of such class shall represent the total number of shares of such class of shares of the company."
