Electronic Origin Data Exchange System (EODES) with China

Procedures for electronic exchange of Preferential Certificates of Origin with China.

Last updated 29 July 2026

Established on 1 November 2019, the EODES enables the electronic submission of Preferential Certificate of Origin (PCO) and the Certificate of Non-Manipulation (CNM) between Singapore and China Customs.

With effect from 1 May 2020, China has implemented full transmission of electronic PCO. This eliminates the need for hard copy PCO or CNM to be dispatched overseas.

EODES shortens the transmission lead time and assures PCO authenticity, thus reducing the goods’ time-to-market through faster Customs clearance.

Submission and Retrieval of e-PCOs

Exporters and their appointed declaring agents/freight forwarders may access the e-service via Customs eServices (opens in new tab) to submit their e-PCOs.

Importers may also access the e-service via Customs eServices (opens in new tab) to retrieve the e-PCOs issued by China for claiming preferential treatment on goods imported into Singapore, or to apply for back-to-back PCOs.

Approximately 10 minutes are required to complete the adjustments and trigger the transmission.

For more information, please refer to Circular 10/2025 on the Implementation of EODES between Singapore and China (opens in new tab)and the Handbook on Transmission and Receipt of Electronic Preferential of Origin (opens in new tab) via Customs eServices’ (opens in new tab) International Connectivity Service (ICS).
