This International Standard specifies a transfer structure, syntax, and coding of messages and data formats when using high-capacity ADC media between trading partners (specifically between suppliers and recipients) and, where applicable, in support of carrier applications, such as bills of lading, and carrier sortation and tracking. The data encoded according to this International Standard include - data which may be used in the shipping, receiving and inventory of transport units; - data which may be contained within supporting documentation, in paper or electronic form, related to unit loads or transport packages; - data which may be used in the sortation and tracking of transport units. This International Standard describes the ISO 646 syntax for automatic data capture. This International Standard is not the controlling specification for data structures (e.g. CII) referenced in this International Standard. This International Standard does not supersede or replace any applicable safety or regulatory marking or labelling requirements. This International Standard is to be applied in addition to any other mandated labelling requirements.
