respond 100 words to stundent robert class 352: This is a great comparison between air and sea freight shipments. The point that you made about the customs inspection is very interesting. Customs inspections is a leading cause to the congestion that many sea ports experience. The containerized freight, while it does not solve the issue, it definitely helps reduce the amount time that containerized freight spends in customs. That is for both containerized freight leaving and entering a port. I paralleled sea and air containerized freight in the purpose of utilizing containerization to expedite the uploading, down-loading, or cross-loading of containerized freight from one mode to another, or holding area. The costs of air freight, containerized or not, is much higher than maritime freight. This plays into the importance of having an efficient supply chain that can plan for longer shipping times to go via vessel, if possible, to safe on transportation costs.
