With the implementation of the Regional Comprehensive Economic Partnership (RCEP) and the General Administration of Customs’ Announcement No.123 of 2023,the traditional "relying on personal connections" model of customs declaration is becoming obsolete.Compliance audits have shifted from manual spot checks to full-process intelligent verification,and 83% of customs declaration errors stem from non-standardized documents (according to customs statistics in 2026).

Three major cognitive traps and compliance logic reconstruction for agency customs declaration

The core conflict in current customs declaration agency lies in the clash between "human experience-driven" and "intelligent supervision systems".The "Smart Customs Power" initiative of the General Administration of Customs requires that all declaration data be electronically verified by 2025,which means that the previous operational space for "supplementing orders" and "deleting and modifying orders" has been completely eliminated.

90% of enterprises overlook the hidden risks in customs declaration

Cross-border e-commerce sellers need to pay attention to the following: 9710/9810 Declaration ModeUnder the "tax-free without invoices" policy,two conditions must be met simultaneously: 1.The enterprise must have registered with the tax bureau as "not having received invoices".2.The inventory data of the exported goods in the overseas warehouse must match the customs declaration form (otherwise,an investigation for "false trade" will be triggered).

For enterprises temporarily importing and exporting goods (supervision mode 2600),they need to submit an extension application to the customs before the end of the fifth month after the goods exit the country (with a maximum of three extensions,each no longer than three months).Otherwise,the goods will be regarded as "general trade imports" and subject to retroactive taxation.

Here are three compliance actions that can be implemented today.
