Container ships burn horrible, cheap bunker fuel, and the shipping industry is infamous for hiring crew from low-income countries like the Philippines, paying them a pittance, and treating them like modern-day slaves.
I'd strongly suspect that the costs for spoilage and knock-on effects from late delivery etc would outstrip crew and fuel costs by a large margin.
