Around 90% of Ukrainian grain exports move through the Black Sea corridor.

Omissions

• The 90% figure describes the traditional/normal routing of Ukrainian grain through Black Sea ports; sources explicitly frame it as 'in peacetime' or 'before the current restrictions'.
• Reuters (15 July 2026) reported Ukraine had lost about a third of its Black Sea grain export capacity because of intensified Russian missile and drone attacks on ports and vessels.
• Reuters (4 August 2026) reported that alternative export routes could replace only about half of Black Sea shipping capacity, and only from end-August 2026 at the earliest.
• No source found gives a precise measured share of Ukrainian grain exports moving through the Black Sea corridor in 2026 itself; the exact current percentage could not be established.
• The 'Black Sea corridor' is a route designation; sources speak of 'Black Sea ports' generally, which is a very close but not identical scope.
