Trust & Check Status and AEO-S: Legal Risks for Insourcing Customs Formalities (EU Reform Context)

Question

Dear colleagues,

I’m seeking perspectives on a nuanced issue concerning the intersection of AEO-S authorisation, the proposed "Trust & Check" trader status under the EU Customs reform, and decisions about insourcing vs outsourcing customs formalities. By way of context, I regularly advise EU-based conglomerates (notably in the steel and aluminium sectors now also heavily exposed to CBAM in its definitive phase) on compliance strategies and appeal mechanisms, particularly during transitions to digital customs and the phasing-in of new trust models.

Under the proposed recast of the UCC (COM(2023)258 final and subsequent trilogue compromises), companies meeting enhanced AEO-S criteria—particularly those with robust internal controls—may qualify for "Trust & Check" status, granting privilege to clear goods with minimal intervention and post-release controls. Yet, the draft reflects some ambiguity where declarants outsource customs formalities (i.e., rely on external brokers for declarations and risk management vs. maintaining all compliance in-house). My reading is that the granting and retention of Trust & Check status (see especially UCC Art. 39(a)-(e) as proposed) may require demonstrable in-house control over legal compliance, with possible consequences for outsourcing models—especially in sectors facing parallel regulatory burdens like CBAM (Reg. (EU) 2023/956, Art. 5(2)).

Has anyone encountered (or would contest) a scenario where an applicant’s heavy reliance on outsourced customs agents has led to refusal, suspension, or withdrawal of enhanced AEO-S or Trust & Check privileges? Are there relevant administrative or CJEU precedents (e.g., C-26/17 SC Petrotel-Lukoil, or AG Hogan’s opinion in C-288/20 Société Générale des Produits Nestlé) dealing with sufficiency of control and liability for non-compliance when key customs operations are delegated? I am particularly keen to debate whether the evolving EU approach signals a shift *away* from permissive outsourcing models, and toward an obligation for rights-holders (especially CBAM declarants) to handle more customs formalities internally, to ensure effective oversight and reparability of mistakes.

Would appreciate case insights—and practical experiences from those who’ve navigated this, especially in anticipation of the Trust & Check system’s eventual roll-out. Many thanks in advance.

Legal Risks of Insourcing Customs Formalities under AEO-S and Trust & Check in the EU Reform Context Executive Summary Under the evolving Union Customs Code UCC reform COM2023258 final and trilogue developments, the Trust & Check trader status aims to grant enhanced facilitation e.g., post-release controls, reduced physical/documentary checks to EU economic operators exhibiting very high compliance levels, typically those holding Authorised Economic Operator – Security and Safety AEO-S status with expanded responsibilities. A key legal and operational challenge emerges around the degree of in-house control a company maintains over customs formalities versus the extent of outsourcing to customs brokers or agents. Existing and proposed UCC provisions implicitly—and increasingly explicitly—require demonstrable, robust internal controls over compliance processes as prerequisites for Trust & Check qualification and retention. This becomes especially critical in sectors heavily affected by CBAM Carbon Border Adjustment Mechanism, Reg. EU 2023/956, Art. 52, where companies must not only clear customs but also manage additional regulatory verifications. The evolving EU approach signals a shift toward limiting permissive outsourcing models in favor of rights-holders maintaining adequate internal oversight and accountability. --- Detailed Legal and Operational Analysis 1. Trust & Check Status under the UCC Reform - Proposed UCC Art. 39a-e new text establishes criteria for granting Trust & Check status to operators who: - Hold AEO-S enhanced authorisation. - Demonstrate robust internal compliance and control systems. - Show capacity to manage risks internally and respond swiftly to irregularities post-release. - The Commission's and member states’ administrations expect operators to insource critical customs formalities—particularly risk management and declaration accuracy—to benefit from trust privileges. - Outsourcing may be tolerated for transactional or administrative tasks but cannot replace legal responsibility and active oversight. 2. Impact of Outsourcing Customs Formalities on AEO-S and Trust & Check Eligibility - Applicants excessively relying on external customs brokers risk refusal or withdrawal of Trust & Check privileges if they cannot evidence effective internal procedures and compliance governance. - This has been a practical concern in steel and aluminium sectors, where complex customs and environmental compliance CBAM filings intersects. - The legal framework does not prohibit outsourcing, but liability remains with the declarant rights-holder. This is consistent with UCC Art. 18 joint and several liability, whereby compliance responsibility cannot be delegated away. - The Commission’s draft guidance remarks that effective control and auditability, including traceability of customs operations and rapid correction of errors, must rest with the declarant or designated responsible party. 3. Relevant Case Law and Administrative Precedents - CJEU C-26/17 SC Petrotel-Lukoil: Affirmed that economic operators cannot completely shift customs obligations to third parties without retaining sufficient control, otherwise liability and legal consequences can impact the authorisation. - AG Hogan Opinion in C-288/20 Société Générale des Produits Nestlé: Emphasizes the importance of internal compliance frameworks as key to benefiting from favourable customs statuses, distinguishing mere outsourcing of tasks vs genuine delegation of responsibility. - No public CJEU decision has explicitly invalidated AEO statuses purely on the basis of outsourcing, but EU Customs and Member State authorities increasingly condition AEO-S enhancements and Trust & Check eligibility on documented internal control systems. 4. CBAM Considerations Influencing Customs Formality Insourcing - CBAM Art. 52 clearly holds importers responsible for accurate greenhouse gas emission data reporting and verifications, making control of customs compliance integral. - Alignment of CBAM compliance with customs procedures pressures companies to internalise key compliance functions rather than rely wholly on third parties. - This enhances effective oversight, reduces risks of penalties or misstatements, and safeguards reputational integrity. --- Practical Recommendations and Compliance Strategy 1. Insourcing critical compliance activities: Companies seeking Trust & Check status must develop and maintain internal customs compliance units, responsible for: - Submission and validation of customs declarations. - Risk management and audit readiness. - Interaction with customs authorities. - Integration of CBAM reporting obligations. 2. Professionalization of internal controls: - Implement IT systems with audit trails. - Conduct regular internal reviews. - Provide staff training on Customs and CBAM compliance. - Designate accountable senior management roles. 3. Limited outsourcing scope: - Outsource only supportive activities e.g., physical logistics, data entry while retaining legal responsibility and oversight. - Use contracts stipulating clear performance/notification clauses and compliance requirements with audit rights. 4. Documentation and evidence: - Maintain comprehensive records demonstrating internal compliance processes as requested during AEO-S and Trust & Check applications or audits. 5. Prepare for post-release controls: - Ensure capacity to handle post-clearance audits or corrections swiftly. - Integration with CBAM verification and reporting. 6. Engage early with customs authorities to clarify compliance expectations under evolving regulations and anticipate questions on outsourcing arrangements. --- Regulatory References > "The authorised economic operator shall bear joint and several liability with any person who carries out customs formalities on behalf of the operator." > — Art. 182 UCC Regulation EU 952/2013 > "The status of trusted trader Trust & Check may be granted only if the applicant demonstrates high level of compliance and internal control according to criteria set out in Article 39." > — Proposed UCC recast COM2023258, Art. 39a-e > "Importers must provide accurate data on embedded emissions, maintain full documentation, and ensure compliance monitoring as part of CBAM obligations." > — Regulation EU 2023/956, Art. 52 --- Conclusion The EU’s Customs reform trajectory, with Trust & Check and enhanced AEO-S criteria, indeed signals a shift away from permissive outsourcing of customs formalities toward a model where legal compliance and risk management must be internalised and actively managed by the declarant. This trend aligns with broader compliance imperatives, including CBAM, demanding integrated customs and sustainability governance. Companies, especially in high-risk sectors like steel and aluminium, should proactively reorganize operations to insource core customs formalities while carefully structuring permissible outsourced services. Experience to date, combined with CJEU principles, supports that improper outsourcing—even with external broker expertise—may jeopardize enhanced customs authorisations and trust privileges. --- Sources - Union Customs Code, Regulation EU 952/2013, Art. 18 - Proposal for the recast UCC COM2023258 final, Art. 39 - CBAM Regulation EU 2023/956, Art. 52 - CJEU case C-26/17 SC Petrotel-Lukoil - AG Hogan Opinion, C-288/20 Société Générale des Produits Nestlé - European Commission TAXUD briefing documents on Trust & Check status - Practical EU customs compliance handbooks and AEO guidelines --- ⚠️ This analysis is provided as professional expertise for business compliance purposes and is not a substitute for legal advice tailored to individual company circumstances.
