Ukrainian corn purchase prices are low due to Russian inspectors delaying vessels to Black Sea ports, causing additional losses for farmers. The backlog has resulted in a queue of 30-50 days for vessels, with one vessel being idle for 84 days. The Russian Federation refuses to speed up inspections and proposes a 60-day extension of the agreement, instead of the 120 days specified, contributing to the supply/demand imbalance in the Ukrainian corn market.
