Electronic Origin Data Exchange System (EODES) with China

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

Last updated 24 February 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.

Exporters and their appointed declaring agents/freight forwarders should leverage on the e-service available on the Networked Trade Platform (NTP). [“Electronic Preferential Certificate of Origin transmitted to The People’s Republic of China” > Government Services > e-service > outbound enquiry > Submit SG PCO (“ePCO”)]

Importers who wish to claim preferential treatment for import of goods from China to Singapore or to apply for a back-to-back PCO can also retrieve the electronic PCO issued by China via the same e-service on NTP. [“Electronic Preferential Certificate of Origin transmitted to The People’s Republic of China” > inbound enquiry > Electronic Preferential Certificate of origin (“ePCO”)]

For more information, please refer to Circular 19/2023 on the updated procedure involving the EODES between Singapore and China, Circular 10/2025 on the Implementation of EODES between Singapore and China under the Regional Comprehensive Economic Partnership (RCEP) and the Handbook on Transmission and Receipt of Electronic Preferential of Origin via Networked Trade Platform’s International Connectivity Service (ICS).
