GB/T 23833-2022Bar code for commodity—Numbering and symbol marking of assets (English PDF)

3.1 Returnable asset

The packaging, containers or transport equipment, etc., which have certain value and are reusable.

Note: Such as beer barrels, high-pressure gas cylinders, plastic pallets or crates, etc.

3.2 Individual asset

A physical entity, which has specific properties.

Note: Such as aircraft parts, rolling stock, tractors, etc.

3.3 Individual asset of an assembly

A single asset, which combines multiple parts, components (assemblies).

3.4 Global returnable asset identifier; GRAI

In the commodity barcode system, a code that is used to uniquely identify returnable asset items on a global scale.

Note: It consists of manufacturer identification code, asset type code, check code, optional serial number.

3.5 Global individual asset identifier; GIAI

In the commodity barcode system, a code that is used to uniquely identify a single asset on a global scale.

4.1.2.2 Asset type code

The asset type code is compiled by the asset owner or manager, who has obtained the manufacturer identification code AND is guaranteed to be unique.

4.1.2.3 Check code

The check code is obtained, according to the calculation method in Appendix B, based on the first 13 digits of GRAI.

4.1.2.4 Serial number

The serial number is the responsibility of the asset owner or manager, who obtains the manufacturer identification code.

4.2 Global individual asset identifier

4.2.1 Code structure

The global individual asset identifier (GIAI) consists of two parts: the manufacturer identification code and the individual asset reference code, which are code characters less than or equal to 30 characters. They are divided into four structures, as shown in Table 2. Among them, the manufacturer identification code consists of 7 ~ 10 digits; the individual asset reference code consists of 1 ~ 23 code characters. The coded character set is in accordance with Appendix A.

4.2.2 Compilation rules

4.2.2.1 Manufacturer identification code

The rules for compiling the manufacturer identification code shall comply with the requirements of GB 12904.

4.2.2.2 Individual asset reference codes

Individual asset reference codes are compiled by the asset owner or manager, who obtained the manufacturer identification code.

4.3 Individual asset codes for global assemblies

4.3.1 Code structure

The structure of the individual asset codes for global assemblies (GIAI-ASSEMBLY) is the same as that in Table 2.

4.3.2 Compilation rules

4.3.2.1 Manufacturer identification code

The compilation rules for manufacturer identification code shall comply with GB 12904.

4.3.2.2 Individual asset reference codes for assemblies

See 4.2.2.2 for the compilation rules of individual asset reference codes for assemblies.

6.1 Requirements for size and level

The size and level requirements for one-dimensional barcode symbol of assets are in accordance with Table 4. The size and level requirements for two-dimensional barcode

B.1 Code position number

The code position serial number refers to the serial number from right to left, including the check code (the code position serial number of the check code is 1).

B.2 Calculation steps

The calculation steps of the check code are as follows:

a) Starting from the code position number 2, sum all the digital codes of even digits;

b) Multiply the sum of step a) by 3;

c) Starting from code position number 3, sum up all the digital codes of odd digits;

d) Add the results of step b) and step c);

e) Subtract the unit digit of the result obtained in step d) from 10, as the check code (if the unit digit is 0, the check code is 0).

Example: For the 14-digit code 0690123456789X1, see Table B.1 for the calculation method of the check code. […]
