Explanation of the meaning of information entities and information elements. Valid value ranges of information entities and information elements and regulations for valid operations on values ​​within the value range. See Table 2 for data types and format representation. Indicates whether an entity or information element is required or optional. See 1.3 for the representation of constraints/conditions. Names that are different from information entity and information element names but represent similar concepts. The set of values ​​allowed by information elements.
Used to represent the size of the same quantity to be compared. Conventions that define the specific quantity used. Units of measurement are given names and symbols by convention: for some quantities of the same magnitude, even if they are not the same kind of quantities, their units may have the same names and symbols; for different objects: the units of measurement are also different. For details, see GB/T 740S Supplementary Notes on Information Entities and Information Elements. The data type of the information entity is "complex type".

4.2.2 Data format
The data format of information elements is expressed in the following forms: a) Character type and numeric type are followed by a positive integer to indicate a fixed-length format; Example 1: (6 indicates a 6-bit fixed-length character: Example 2: V16 indicates a 16-bit fixed-length value b) Character type and numeric type are followed by "\x..y" to indicate a format from the smallest to the largest length; Example 3: (1.10 indicates a character with a short length of 1 bit and a maximum length of 10 bits: Example 4: NI..6 indicates a value with a short length of 1 bit and a maximum length of 6 bits c) Character type is followed by "..ul" to indicate a format with an uncertain length Example 5: C..ul indicates a character with an uncertain length, which is mostly human-valued content, d) Numeric type (N) is followed by "..xy\ to indicate a decimal place: Example 6: V..17, 2 indicates a value with a maximum of 17 digits and two decimal places. C) Binary stream (1Y) can be followed by the media format of the body. Indicates different formats. Example 7: BY-JPEG indicates "IPEG\ format file. Indication of constraints/conditions
Used to indicate whether a information entity or information element is mandatory or optional. The representation method is as follows: a) M: Mandatory, indicating that the information entity or information element is mandatory: GB/T40037—2021
b) C: Conditionally mandatory, indicating that the information entity or information element is mandatory under certain conditions. It should be selected when the conditions defined in the constraints are met. The specific conditions are described in the remarks; (: Optional, indicating that the information entity or information element is optional according to actual use.)
5 Commodity classification
5.1 Overview|| tt||Commodity classification is an important part of commodity information description. Commodity classification includes but is not limited to: a) The major categories of bulk commodities are energy and chemical industry, basic raw materials and agricultural and sideline products; b) Different industries can further divide bulk commodities in the industry into medium, small and large categories according to the characteristics of the industry; c) The spot trading market or platform of bulk commodities can further classify the traded bulk commodities according to the actual trading needs: using commodity attribute codes:
2 Coding method
The coding of bulk commodity classification in e-commerce transactions consists of the classification code of bulk commodities and the commodity attribute code. The classification code adopts 8 digits and 4 segments. The coding requirements include but are not limited to: a) The first and second digits of the code represent the major category:
b) The 3rd and 4th digits of the code represent the sub-category;
c) The 5th and 6th digits of the code represent the sub-category; The digit code indicates a subcategory;
dl) The 7.8th digit indicates the group:
The character "0" in the code is used to fill in the code of the higher level to achieve a unified digit length of the code in the code table, and it should not be used in other cases;
The character derivative \99"-share is used to indicate "others" f)
The coding structure is shown in the figure, and the examples of the classification of commodities in the chemical industry are shown in Appendix A3
