Lessons identified?

  • Is shipping weight provided final and accurate?
  • Are shipping dimensions provided final and accurate?
  • Is the shipment covered by a Letter of credit and, if so, where is it?
  • Are there dangerous goods in the shipment – and, if so, are they properly packaged and declared?
  • For over-sized cargoes loaded to vessel, rail, truck – when and how often is the lashing being re-checked? – as even the best tie-down schemes can loosen during transit
  • Is the cargo professionally and sufficiently insured?
  • Are related parties named ‘additional insured’ on the insurance certificate to reduce corporate exposure?
  • Are the products being shipped subject to import, export, and/or transit permits and are these in place before the cargo movement starts?
  • Does the shipping documentation accurately describe the cargo and the movement – and are the various documents consistent?
  • On very large units, is an independent surveyor and/or company rep. present at key intermodal points to provide up-to-date info, photos, and to intervene as required?
  • Are weights in lbs or kilos?
