Dev said she had urged the Centre and the finance minister to exempt GST on sanitary napkins.
"If the price is subsidised, it becomes a product that is affordable in the rural market, so private companies take it there," she said.
Dev claimed the BJP will not win a single seat in Meghalaya, and its similar promise of free sanitary napkins will not happen.
She accused the saffron party of not being serious about the security of women.
Dev also took a jibe at Union Minister Smriti Irani who campaigned here yesterday.
"We need to ask a lot of questions on the leaders of the BJP who are coming to Meghalaya and talking about the security of women," she added.
