The supply chain is as follows ; Farms -> Harvest -> Packinghouse/Selection -> Sales/Logistics
Farmers supply according to harvesting programs related to purchase orders. However, suppliers buy from other suppliers once or twice (very rarely) to meet the buyers' demand.
Suppliers export both directly and via traders or corporate firms. Big farms usually possess their own packing houses. There are around 3 renowned packing houses in Colima; the industry is not so saturated.
There is a kind of oligopoly in the supply chain, mostly to control processes and quality.
Agents do not play a big role, but they can be important in terms of easiness, volumes, invoices (fiscal procedures). Middlemen include only brokers and traders.
