It was the eighth shipment sent to North Korea since last November to help residents affected by massive 1995 floods that swept away homes and fields.
Previous shipments had included blankets, instant noodles, powered milk, and cooking oil worth $1.5 million.
The next shipment of $222,000 worth of flour is to depart from Inchon port next Monday.
Seoul has said the North can expect substantial government aid if it improves political relations with the South, but so far, the North has refused.
The two Koreas have been bitter enemies since their 1950-53 Korean War.
