Traders in Kathmandu are protesting the government's decision to impose a 13% VAT on imported potatoes, onions, and other vegetables, leading to a shortage of these items in the market. The Potato Onion Traders Association has stopped supplying these products and warned retailers of fines up to Rs 100,000 for selling them. The government's decision to tax these essential food items has led to protests, and the Ministry of Agriculture and Livestock Development is working to address the traders' concerns by distinguishing between locally produced and imported items for tax purposes.
