Container traffic for the April-September period was estimated at 37,236 20-foot equivalent units, compared with 27,411 TEUs in the year-ago period.
Volume in September increased to 6,942 TEUs from 4,226 TEUs in the same month last year.
Officials attributed the growth in traffic to several proactive measures the authority has taken in recent months, covering reduction in handling costs and other concessions to users.
The measures include additional free days for cargo and containers, pre-shipment and long-term storage facilities, and reduction in midstream stevedoring charges for loading as well as discharging operations.
The west coast hub handled 27.38 million tons of cargo in the first half, up 3.33 percent from 26.5 million tons a year earlier.
Overall tonnage fell just short of the Shipping Ministry’s target of 28 million tons set for the six-month period.
The volume of petroleum products was up 22 percent and breakbulk cargo up 12 percent in the April-September period.
Mumbai, one of India's leading general cargo gateways, suffered a 20 percent drop in tonnage in August because of serious operational disruptions caused by the MSC Chitra-Khalijia-3 collision Aug. 7, and the latest data indicates the volume recovery will accelerate in the coming months amid signs of a significant turnaround in the country’s foreign trade.
