The average weight of units in containers in a number of trades is stated to be about 50 killogrammes and, if the "container formula" applies, this would mean 100 SDR if the limitation amount equals 2 SDR and 460.5 SDR if the limitation amount equals 8.33 SDR. These amounts should be compared with the limitation of the Hague-Visby Rules which amounts to 666.67 SDR.
