Frequently asked questions

  • What is the CAx?

    The CAx (Container Availability Index) is an index (or tool) that allows interested parties to monitor the import and export moves of full containers around major ports. A CAx value of 0.5 means that the same amount of containers leave and enter a port in the same week. CAx values of > 0.5 means that more containers enter and CAx values of < 0.5 means more containers leave a specific port.

  • What data is included/not included in the CAx?
    • The CAx includes:
      • Gate-in and gate-out moves of containers (or import and exports of containers)
      • An estimation of manufactured containers in China
      • 20ft and 40ft containers
    • The CAx does not include:
      • Empty repositioning of containers by carriers
      • Containers sold locally in certain locations
      • Exact number of manufactured containers
  • Which equipment types are included in the CAx?

    This section is based on a a big sample of our tracking data. It should however be considered as a rough segmentation as the percentages might slightly changed for each update.

    • 20ft containers:
      • 98% are 20DC
      • 2% are a mix of different other equipment types (20HC, 20OT, 20RF..)
    • 40ft containers:
      • 55% are 40HC
      • 33% are 40DC
      • 7% are 40HC RF (forty high cube reefer containers)
      • 5% are a mix of different other equipment types (40RF, 40DC, 40FR..)
  • How to interpret the CAx major cases?

    This section provides an overview of some interpretations that one can derive from the CAx.

    • A CAx between 0 and 0.45:
      • More demand for export containers than full imports
      • Likely resulting in increased container rental fees
      • Likely delays cargo acceptance
      • Could be the result of an increase in cargo production output if the CAx is considerably lower than the long-term average
      • If for a longer time below 0.45
        • The port is likely not importing enough containers to handle the full exports
        • Likely a shortage of containers
        • Likely receiving empty imports to ease the shortage
      • A CAx between 0.55 and 1:
        • Less demand for export containers than full imports
        • Likely resulting in decreased container rental fees
        • Could be the result of a decrease in cargo production output if the CAx is considerably higher than the long-term average
        • If for a longer time above 0.55
          • If it happens during/after shortage:
            • This is likely a sign that the shortage is easing in this port
          • If there is no apparent shortage
            • The amount of full exports is likely not sufficient to decrease the surplus
            • The surplus could be a result of the empty containers that were moved out of this port in previous weeks and now are returning as full imports
          • A CAx between 0.45 and 0.55:
            • Balanced demand for export containers and full imports
            • If for a longer time between 0.45 and 0.55:
              • Decrease in empty exports and imports in this port
              • Stable cargo production output
  • Why does the CAx show values higher than 0.5 while the concerned port is known for currently experiencing a shortage?

    The CAx is an indication of how many full containers were imported vs. exported. This value should therefore serve as a tool to comprehend the imbalance of container moves in a certain location in a specific week. Although the CAx is showing high values, this does not mean all those containers are available. Moreover, the high number of imports could be the result of the shipping companies trying to ease the shortage by exporting more containers to that specific port. All in all, the CAx is solely an indication of entering vs. leaving containers, what this implies is up to interpretation and depends on each different port.
