Korea lettuce price increase more than 20% compared to 2020

Korean lettuce's price has increased more than 20% compared to 2020. The cost of 8-10kg/carton was around 9-ish USD in 2020, and it's around 11-ish USD in 2021. The importers are still sourcing the Korean lettuce despite the price increase to diversify the origins of the imported lettuce to minimize the risk of international trading caused by the delay of shipments and congestions at ports.
