OCTOBER 1 is D-day for implementation of the new Single Administrative Document (SAD) which will replace the CCA1 as the only cross-border transport document in the Southern African Development Community (SADC). According to Riaan de Lange, who runs the customs and trade consultancy, SA Tariff & Trade Solutions, the new SAD 500 is based on the same-named European version which supplies customs (and its tax-gathering parent Sars) with statistical information and record of goods moved.
