CPTPP Procurement Chapter

The CPTPP Procurement Chapter establishes the rules and market access commitments for government procurement among the members of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership. CPTPP entered into force in December 2018 for the original six ratifying members and has since grown to include additional economies. Its procurement chapter is directly relevant to European suppliers because the United Kingdom formally acceded to CPTPP in December 2024, making it a binding framework for UK suppliers and buyers operating in CPTPP member markets.

What is the CPTPP Procurement Chapter?

Chapter 15 of CPTPP is modelled closely on the WTO Government Procurement Agreement and incorporates many of its disciplines by reference. The core obligations include:

Non-discrimination and national treatment. Covered contracting entities must treat suppliers, goods, and services from any CPTPP party no less favourably than those from the procuring entity's own country or any other CPTPP party. This mirrors the GPA's national treatment principle.

Transparency. Contracting entities must publish notice of covered procurement opportunities, provide tender documentation, and disclose evaluation results. The chapter specifies minimum time limits for the submission of tenders and notice periods for contract opportunities.

Coverage schedules. Like the GPA, each CPTPP party appends its own schedule of covered entities, goods, and services, along with threshold values and general notes. Coverage is therefore not uniform across all CPTPP parties: each party's schedule reflects its negotiated commitments.

Electronic procurement. CPTPP explicitly encourages electronic tendering and the use of electronic means throughout the procurement process, a provision that has practical implications for how opportunities are published and how bids must be submitted.

Challenge procedures. Each party must maintain a review mechanism for suppliers who believe a covered procurement has been conducted in breach of Chapter 15 obligations. The requirements parallel the GPA's challenge procedure standards.

CPTPP members as of 2025 include Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, Vietnam, and the United Kingdom. The UK's accession is particularly significant for European (non-UK) suppliers, as UK buyers are now subject to CPTPP obligations towards suppliers from those markets.

Why it matters for bidders

For UK-based suppliers, CPTPP accession creates legally enforceable access rights to covered government contracts in markets such as Japan, Canada, Australia, and Vietnam. These are markets that many UK companies already compete in, but CPTPP formalises and strengthens the legal basis for that competition beyond what the GPA alone provides, particularly for sub-central entities and sectors not fully covered under GPA schedules.

For non-UK European suppliers, CPTPP is not directly applicable (the EU is not a CPTPP member), but the agreement shapes the competitive landscape. UK suppliers now have CPTPP-backed access to some markets where EU suppliers must rely solely on bilateral EU FTA procurement chapters or the GPA, and this may affect competitive dynamics in tenders where European and UK suppliers are competing for the same contracts.

The UK's CPTPP accession also creates obligations on UK contracting authorities towards CPTPP-party suppliers. A German subsidiary tendering in the UK cannot rely on CPTPP (it is not a CPTPP-party supplier), but an Australian or Japanese company can. UK buyers must ensure their procurement procedures comply with Chapter 15 for covered contracts.

Example

A UK-based environmental consultancy wants to bid on a Japanese prefectural government environmental assessment contract. Japan has listed certain prefectural entities in its CPTPP Annex and the services are within the covered CPC codes. The contract value exceeds Japan's CPTPP sub-central threshold. Under Chapter 15, the UK firm has access rights equivalent to domestic Japanese suppliers for this contract, a right that is more extensive than the GPA alone would provide because Japan's CPTPP sub-central coverage is broader than its GPA sub-central schedule.

Frequently Asked Questions

Is the CPTPP Procurement Chapter the same as the GPA for covered contracts?

The disciplines are very similar in structure and content, and Chapter 15 explicitly incorporates GPA disciplines by reference in several provisions. The practical differences lie in the coverage schedules: CPTPP parties have made specific commitments that may differ from their GPA schedules. Some CPTPP parties have opened more at sub-central level under CPTPP than under the GPA; others have maintained similar scope. Suppliers should check both instruments for any given market.

Can EU suppliers benefit from CPTPP procurement rights?

No. The EU is not a CPTPP member and EU suppliers do not have CPTPP rights. The EU has its own network of bilateral FTA procurement chapters covering some CPTPP member markets (such as Japan, Singapore, and Canada via CETA), but the scope may differ. EU suppliers targeting markets like Australia, New Zealand, or Vietnam must rely on EU-specific bilateral agreements or, if the country is a GPA party, on GPA coverage schedules.

What happens to UK procurement obligations after CPTPP accession?

UK contracting authorities that are listed in the UK's CPTPP Annex and are conducting procurement above the relevant CPTPP thresholds must comply with Chapter 15 obligations towards suppliers from all CPTPP parties. The UK's domestic framework under the Procurement Act 2023 implements these obligations. Where a procurement is covered by both GPA and CPTPP, the UK must satisfy whichever instrument imposes the stricter or broader obligation.
