4.3 Basic data units
4.3.1 General rules
4.3.1.1 Whether a data unit is mandatory or optional depends on the industry. Market or individual trading partner requirements (see Table 2). These data cells may be human-readable, machine-readable or expressed in a web-based format. If machine-readable, the data cells shall comply with the relevant requirements of ISO/IEC 15418.
4.3.1.2 For a wide range of product packaging applications, some specific data units are required, including:
4.3.2 Item identification
4.3.2.1 Item identification may be assigned to either the supplier or the customer. The label may show the customer's item identification, the supplier's item identification or both, depending on the outcome of negotiations between the trading parties. If both are displayed on the label, at least one of the two item identifiers should be coded as a machine-readable symbol.
4.3.2.2 If there is no other agreement between the parties to the transaction, the supplier's part code shall be used as the item identification.
4.3.2.3 The maximum length of a data unit is 25 alphanumeric characters, excluding the corresponding application identifier or data identifier.
4.3.2.4 It is desirable that the item identification data field be in any of the formats shown in Tables 3 and 4. These identifiers identify the most common formats used for product packaging. A full list of item identifiers can be found in ISO/IEC 15418 and the GS1 application identifier consistent with GB/T 16986.
4.4 Additional data units
4.4.1 General rules
Whether a data unit is mandatory or optional depends on the requirements of the industry, the market or the individual trading partners. In addition to the data specified in Table 2, the following data units can also be found in common use. These data units can be human-readable, machine-readable or both.

The use of 2D barcodes and the specific 2D barcode code system to be used should be agreed between trading partners. Users are advised to ensure that the scanning technology selected is capable of reading the barcode symbologies they choose to read.
4.6.4.1.3 - 2D imaging scanning or 2D laser scanning technology can read both 1D barcodes and PDF417 barcodes. Hanson, Data Matrix ECC 200 and QR codes require the use of 2D imaging scanning technology.
4.7 Label size and layout
4.7.1 Size of labels
The size of the label should be adapted to the size of the package and may also be influenced by the space required for the information. 4.7.2 Label layout
4.7.2.1 The label layout refers to the placement of the individual fields on the label. The layout of a 1D or 2D barcode will be influenced by the space available on the label, packaging technology and other factors.
4.7.2.2 When placing multiple 1D barcodes, or 2D barcode symbols in a row or in consecutive fields, it is advisable to take care that the layout does not interfere with the scanning of individual data units. The layout of the label format should be designed to suit the size of the package and to facilitate barcode scanning.
