At least 30,000 metric tons of cocoa are trapped on their way to ports in Nigeria’s main city of Lagos as roads in a state of disrepair delay access to ships, the cocoa exporters body said.

Travel to the Apapa and Tin Can Island ports that previously took hours, now takes as much as four weeks as trucks struggle through cratered and water-logged roads to get there, Pius Ayodele, president of the Cocoa Exporters Association of Nigeria, said. The affected cargoes are either in traffic jams or stored in transit warehouses in Lagos.

“A greater part of this travel time is spent at the epicenter of the congestion which is just 6 kilometers (3.7 miles) to the ports,” Ayodele said by phone from the southwestern cocoa-trading center of Akure.

Nigeria currently ranks a joint fifth with neighboring Cameroon among the world’s biggest cocoa producers, with the International Cocoa Organization estimating its 2017-18 output at 240,000 metric tons. Access roads to the ports were left to decay by a succession of governments over the past two decades, now slowing everything ranging from cocoa exports to gasoline imports, escalating costs and taking a significant toll on economic activity, according to the Lagos Chamber of Commerce and Industry.

Haulage costs have gone up “about 400 percent because of the turnaround time to get to the ports, to get loaded and get out of the ports,” Muda Yusuf, director general of the Lagos Chamber of Commerce and Industry, said in an interview in Lagos. This will either erode the profit margins of companies or get passed on to consumers, Yusuf said.

Price Drop

Shipment delays are making it difficult for exporters to get credit from banks to finance their operations, according to Akin Olusuyi, president of the Cocoa Processors Association of Nigeria, who said 1,760 tons of cocoa butter and cake are held up in the gridlock to the ports.

“Most of them have been in the traffic to the ports for close to three weeks and are still far away from its gates,” he said. “The cargoes that would have translated into export proceeds for us are locked up in that horrific traffic.”

Farm-gate cocoa prices have dropped as purchases have slowed because of the difficulties in reaching the ports, according to local buying agents. Prices have fallen from 800,000 naira ($2,208) per ton in July to 640,000 naira, according to Wale Shittu, managing director of Agrotrack Ltd., a cocoa-buying company.
