Costa Rica completes CPTPP accession negotiations
The UK Department for Business and Trade confirmed on 6 May 2026 that Costa Rica's CPTPP (Comprehensive and Progressive Agreement for Trans-Pacific Partnership) Accession Working Group has concluded its negotiations. This milestone moves Costa Rica closer to full membership in the 11-nation trade bloc, which includes the UK, Canada, Australia, Japan, and others. Shippers exporting to or importing from Costa Rica should monitor for tariff-rate changes and new preferential-origin rules once Costa Rica formally accedes.

The UK Department for Business and Trade announced on 6 May 2026 that Costa Rica's CPTPP Accession Working Group has completed its negotiation phase. This concludes a critical step in Costa Rica's path to joining the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, a 12-member trade pact (including the UK, Canada, Australia, Japan, Singapore, Vietnam, Malaysia, Brunei, Chile, Mexico, New Zealand, and Peru).
What accession means for Costa Rican trade
Costa Rica's formal accession to CPTPP—pending ratification by existing member states—will:
- Establish reciprocal duty reductions on goods traded between Costa Rica and all CPTPP members
- Create new rules of origin for chapters across agriculture, machinery, chemicals, and textiles
- Align Costa Rica's tariff schedules with CPTPP commitments
- Grant Costa Rican exporters preferential access to 500+ million consumers across CPTPP member economies
The working group's conclusion signals that member states have resolved outstanding commodity, service, and intellectual-property disputes. Formal accession typically follows within 6–18 months of working-group sign-off, subject to legislative approval in each member country.
Impact on importers and exporters
Shippers with Costa Rican suppliers (coffee, bananas, fresh fruit, sugar, semiconductor components, optical instruments, and machinery—chapters 2, 6, 7, 8, 9, 10, 17, 29, 30, 38, 39, 48, 84, 85, 87, and 90) should expect tariff relief once Costa Rica accedes. UK exporters to Costa Rica will similarly gain preferential rates on products classified under chapters 25, 39, 48, 62, 63, 64, 84, and 85.
Until formal accession is complete and implemental regulations are published, shippers must continue applying Most-Favoured-Nation (MFN) tariff rates on Costa Rican origin goods and pay full tariffs on UK exports to Costa Rica.
What this means for shippers
Monitor the UK Department for Business and Trade and CPTPP secretariat websites for Costa Rica's formal accession date and implemental rules. Once Costa Rica joins, you must review and update your landed-cost models, preferential-origin calculations, and supplier sourcing for any goods in the chapters listed above. Failure to apply CPTPP rates on day one of accession leaves money on the table; proactive HS-code and origin-documentation review now shortens your compliance window.
