On 23 October 2025, the World Customs Organization (WCO) advised that Costa Rica had acceded to the International Convention on the simplification and harmonisation of customs procedures done at Kyoto, Japan, on 18 May 1973 and amended on 26 June 1999, widely known as the Revised Kyoto Convention (RKC), thereby becoming its 140th Contracting Party.
The Instrument of Accession of Costa Rica was deposited with the Secretary General of the WCO on 23 October 2025, by the Ambassador of the Embassy of Costa Rica to Belgium.
Costa Rica becomes the 12th WCO member out of 33 in the South America, North America, Central America and the Caribbean region to accede to RKC, contributing to the global total of 140 contracting parties out of the 187 WCO members.
The WCO will continue to support Costa Rica in the effective implementation of the RKC, for the benefit of its Customs administration, trade community, and society at large.
