Cross-border B2C export planning should start with the customs supervision model and the electronic data that the platform, payment provider and logistics provider must transmit. China Customs’ online guide describes the declaration and data responsibilities; a 2026 official announcement separately addresses cross-border returns. [1] [2]
Separate the operating questions
- Which supervision code and export model matches the transaction?
- Who is responsible for the authenticity of transaction, payment and logistics data?
- How will returns be declared and linked to the original export?
- Which tax treatment applies to the actual product and documentation?
Return handling and tax treatment should be checked against the current implementation for the chosen model and product.
Seller control
Keep product descriptions, buyer orders, payment data, logistics data, customs codes and return records aligned. The correct process is determined by the transaction and the current local implementation, not by a generic “pilot-zone” label.
