Agents involved in the sale of sugar.

The world needs sugar from top producer Brazil more than ever to help ease global shortages. Congestion at key ports means the country can’t ship it fast enough.

More than a decade after port logjams plagued Latin America’s biggest economy — sending sugar prices rallying — logistics are being stretched to their maximum again. Approximately 70 vessels are waiting some 20 days to load over 3 million tons of sugar in the country. That’s equivalent to a month of exports.
