Starting August 15, 2020, Sri Lanka increased the special commodity levy para-tariff tax on potatoes from 50 rupees to 55 rupees per kilogram. This tax, which has been in place to protect potato farmers and promote them as a non-competitive export, is also applied to onions. The policy was introduced in the early 1980s to protect farmers during economic reforms, but it has been criticized for contributing to currency devaluation and high inflation rates.
