Background: The European Union (EU) increasingly uses environmental conditionality as a market-access governance technique through border controls, traceability requirements, sustainability reporting, supply chain due diligence, and country-based risk assessment. Although many obligations are formally imposed on EU operators, compliance costs and evidentiary burdens are frequently borne upstream by third-country suppliers. For Vietnamese exporters, this creates a procedural gap: they may suffer commercial, reputational, and exclusionary harm while remaining peripheral to the decision-making and review structures that shape access to the EU market. The article examines that gap through access to justice, focusing on Article 263 TFEU and mediated safeguards.
Method: The article employs doctrinal legal analysis to examine standing and reviewability constraints under Article 263 TFEU and selected EU environmental market-access instruments. It uses law-in-context reasoning to assess how EU regulatory architectures operate through supply chains and affect Vietnamese exporters. The EU's yellow-card process for illegal, unreported, and unregulated (IUU) fishing against Vietnam is used as an illustrative case study because it clearly demonstrates the mismatch between the formal procedural addressee, the third-country state, and the private exporters who bear operational and economic burdens.
Results and Conclusions: The article finds that Vietnamese exporters operate in a structurally asymmetric procedural environment. Direct action before EU courts remains constrained by restrictive standing doctrine, while Article 267 TFEU offers only a contingent, indirect route that depends on proceedings before Member State courts. The IUU yellow card illustrates how reason-giving and participation are concentrated in Commission-state dialogue, while exporters bear intensified documentary, traceability, and reputational burdens. The article concludes that meaningful indirect access to justice depends on domestic institutional design. It proposes a single-window export spillover response mechanism, standardised evidence templates, time-bound reasoned responses, and interoperable compliance information systems linked to the EVFTA Trade and Sustainable Development dialogue and follow-up.
