Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of import and export commodity management in international trade, and in particular to a model for HS Code pre-classification of customs declaration commodities. Background Art
[0002] HS Code stands for Harmonized System Code, also known as customs code or coordinated system code, which is an internationally accepted commodity classification system. It was developed by the World Customs Organization to unify the classification and coding of import and export commodities in various countries. HS Code is widely used in trade, logistics, tariffs and other aspects around the world.
[0003] In the prior art, one commodity corresponds to only one HS Code, and one HS Code corresponds to more than one commodity. However, when the actual situation is complicated, there will be differences. For example, in the case of textiles, two commodities that look similar contain cotton and chemical fibers of the same quality, but due to different proportions, the resulting HS Codes will be different. Furthermore, the same commodity with different uses can sometimes be declared for customs clearance with different HS Codes. For example, the HS Codes used for corrugated boxes imported as paper goods and as packaging materials are also different. A commodity item can only have one code, or a code can only identify one commodity item. Commodities of different specifications, packaging, varieties, prices, quantities, and even colors can only use different commodity codes; therefore, it is difficult to accurately determine the item to which the declared commodity belongs from the obtained HS Code, resulting in incorrect classification of commodities and bringing risks to import and export trade. Summary of the invention
[0004] In order to solve the above technical problems, the present invention provides a model for HS Code pre-classification of declared goods, and its technical solution is as follows: One aspect of the present invention provides a method for pre-classifying HS Code of declared goods, comprising: Step 1) Establish a standby database; Step 2) Collect information on goods to be declared; Step 3) Integrate the information based on the information collected in step 2); Step 4) Input the integrated information into the pre-classification processing module to obtain the customs declaration commodity code; Step 5) Input the customs declaration commodity code obtained in step 4) into the verification module for verification to obtain a verification result; if the customs declaration commodity code verification result is HS Code, output HS Code; if the customs declaration commodity code verification result is not HS Code, execute steps 2) to 5) again.
[0005] Further, in step 1), establishing the backup database involves converting the customs declaration commodity names and codes into model statements for backup. The backup database established in step 1) complies with the provisions of relevant conventions and annotations, including: the Convention on the Harmonized Commodity Description and Coding System, the Explanatory Notes on Commodities and Categories in the Import and Export Tariff, the Explanatory Notes on Commodities and Categories in the Import and Export Tariff, and the Explanatory Notes on National Subheadings of the Import and Export Tariff of the People's Republic of China.
[0006] Further, the information collected in step 2) includes the customs declaration commodity name, customs declaration commodity specifications, customs declaration commodity materials, customs declaration commodity composition, and customs declaration commodity uses.
[0007] Further, the information integration performed in step 3) involves converting the customs declaration commodity information collected in step 2) into model statements.
[0008] Further, the pre-classification processing module in step 4) includes a classification database. The pre-classification processing module in step 4) supports statement input and statement processing functions, and the pre-classification processing module in step 4) uses the random forest algorithm.
[0009] Further, the programming of the pre-classification processing module in step 4) complies with the set principles, and the set principles include: Rule 1, search scope; Rule 2, understanding of tariff items; Rule 3, selection of tariff numbers; Rule 4, fallback clause; Rule 5, packaging; Rule 6, subheading notes.
[0010] Further, Rule 1, Rule 2, Rule 3, and Rule 4 are in a logical order; Rule 1, the Rule, Rule 3, and Rule 4 are used sequentially from front to back; Rule 2 is in a parallel and juxtaposed relationship; Rule 5 and Rule 6 are independent of each other.
[0011] Further, the customs declaration commodity code obtained in step 4) complies with the provisions of the Convention on the Harmonized Commodity Description and Coding System.
[0012] Further, the verification module includes a verification database, and the data in the verification database comes from official classification decisions and classification pre-rulings.
[0013] In another aspect of the present invention, an electronic device is provided, including a processor and a memory. The memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to execute the above-mentioned method for pre-classifying the HS Code of customs declaration commodities.
[0014] Compared with the prior art, the beneficial effects are as follows: By adopting the technical solution of the present invention, the obtained HS Code can accurately determine the heading of the declared goods. Combining with the official customs classification preliminary ruling will greatly reduce the trade risks brought about by misclassification of goods. BRIEF DESCRIPTION OF THE DRAWINGS
