Between January and September 2026, three types of cargo accounted for most of the coastal shipping cargo handled at Mexican ports, according to CGPMM statistics.
Mexican ports handled 41,415,175 tonnes of coastal shipping cargo between January and September 2026, 6.5% more than in the same period of 2025, according to preliminary statistics from the General Coordination of Ports and Merchant Marine (CGPMM).
Coastal shipping refers to maritime transport between domestic ports, unlike international maritime traffic, which involves movements between Mexican and foreign ports.
Petroleum and petroleum products led coastal shipping cargo movements with 18.4 million tonnes between January and September 2026, according to the CGPMM. This category accounted for approximately 44.4% of total cargo transported under this shipping modality.
They were followed by general cargo, with 11.1 million tonnes, and mineral bulk cargo, with 11 million. Together, these three categories accounted for approximately 97.9% of Mexico's total coastal shipping cargo movements. Smaller volumes of containerized cargo, agricultural bulk cargo and other liquid bulk cargo were also transported, according to official statistics.
Compared with January–September 2025, petroleum and petroleum products movements increased by 20.3%, while general cargo and mineral bulk cargo recorded year-on-year declines, according to the CGPMM.
Dos Bocas recorded the highest coastal shipping cargo volume between January and September 2026, with 5,732,786 tonnes, according to CGPMM statistics. Of that total, 3,690,367 tonnes corresponded to outbound shipments of petroleum and petroleum products.
It was followed by Salina Cruz with 3,259,945 tonnes, and Isla de Cedros with 3,128,230 tonnes. Guerrero Negro ranked fourth with 3,108,450 tonnes.
Meanwhile, Lázaro Cárdenas handled 2,700,123 tonnes during the same period. These five ports recorded the highest volumes of coastal shipping cargo in Mexico between January and September 2026, according to CGPMM statistics.
