ICC recommends FCA instead of FOB in containerized shipments. But why?

FOB (Free on Board) and FCA (Free Carrier) are two well-known and frequently used trade terms of Incoterms 2010.

Both FOB anf FCA have been in circulation for a long period of time, as they been defined under previous versions of Incoterms.

FOB is one of the oldest incoterms, which has been created in 1923. FCA introduced to the export-import world in 1980.

ICC recommends FCA instead of FOB in containerized shipments.

ICC included a warning message in Incoterms 2010, which catches the most practitioners by surprise.

One of the explanatory paragraphs under the FOB rule states that:
FOB may not be appropriate where goods are handed over to the carrier before they are on board the vessel, for example goods in containers, which are typically delivered at a terminal. In such situations, the FCA rule should be used.

Until the issuance of the Incoterms 2010 rules, may be hundreds of millions of containers have been loaded under FOB terms without any problem. 

In such case why ICC puts this warning message in incoterms 2010 explanations:

Here is the logic of the ICC:
  • What ICC figured it out from the general international freight container transportation is that the containers are being received by the carriers at the container terminals of the port of loading, long before they have been shipped on board a named vessel. 
  • By accepting a FOB trade term in a containerized shipment, exporters have to bear extra risk, which responds to the time between the container received by the carrier at the container terminal of the port of loading and shipped on board of the container to the named vessel. 
  • In order to eliminate any wrong usage of the FOB trade term, ICC included above warning text to the FOB trade term explanations.
