What is the difference between commodity classification and pre-classification in customs declaration level test?

The Decision on Commodity Classification is a difficult commodity classification announcement issued regularly by the General Administration of Customs every year. The prefix of the document number is usually Z, W or J, which is applicable to customs areas all over the country. Pre-classification decision is a pre-classification decision issued by the customs of the municipality directly under the central government for the import and export enterprises to apply for pre-classification. The document number is prefixed with R and is applicable to the customs of the municipality directly under the Central Government.

If you work in an enterprise, it is necessary to know that if the products of the enterprise are relatively single, you can consult the pre-classification company when you encounter products that you don't know how to classify. "Commodity classification" is one of the main factors that affect the tariff collection, agreed tax rate and preferential tax rate of import and export goods, affecting tariff collection, goods supervision conditions, trade sanctions, trade security and so on.

According to the relevant announcement of customs classification, the pre-classification of social services has no legal effect, only the pre-determination (classification) applicable to the customs directly under the Central Government and the classification decision of the General Administration have legal effect. Therefore, if the pre-classification made by the pre-classifier is in doubt, the customs will not recognize it.
