CBAM 2026 and Enforcement Risk: What Are the Legal Liabilities for the Transport and Logistics Sector?

With the official entry into the definitive regime of the Carbon Border Adjustment Mechanism (CBAM) on 2026年1月1日, the mechanism has ceased to be a mere environmental reporting requirement. It has transformed into one of the most complex and heavily sanctioned variables of European Union customs law.

While energy-intensive industrial sectors (steel, aluminum, cement, fertilizers, hydrogen, and electricity) view CBAM as a challenge to their market competitiveness, operators in the transport, freight forwarding, and logistics sector face a substantial increase in Enforcement Risk (sanction and compliance compliance exposure).

The Legal Trap of Indirect Customs Representation

The most critical node for logistics companies lies in their method of interaction with customs authorities. When a freight forwarder or carrier acts in the capacity of an indirect customs representative (pursuant to Art. 18 of the Union Customs Code – UCC), they become jointly and severally liable with the importer for customs debts and the compliance of the declarations.

Under the definitive regime in force since 2026, importing CBAM-governed goods requires mandatory status as an Authorized CBAM Declarant if the new single cumulative threshold of 50 annual tons of net mass (introduced by recent regulatory corrections, including EU Regulation 2025/2083) is exceeded. Executing customs clearance for bound goods without this prior authorization, or submitting incorrect data regarding embedded emissions, directly exposes the logistics operator to severe administrative penalties, border cargo holds, and commercial litigation.

Risk Factor Analysis in the Global Supply Chain

Recent studies highlight how the transition to the definitive regime is heavily straining European supply chains, with direct impacts on transport flows:

1. Vulnerability of Downstream Manufacturing: As noted by analyses of the fastener industry, the indirect extension of CBAM’s effects to semi-finished goods and assembled components makes collecting Scope 1 and Scope 2 emissions data highly complex. The reluctance or inability of non-EU suppliers (particularly in Asian markets) to provide validated reports translates into chronic customs bottlenecks. For carriers, this results in an exponential increase in vessel/vehicle idle times, demurrage costs, and the risk of disputes for breach of contract.
2. Regulatory Instability and the Article 27a Question: The legal debate sparked in February 2026 regarding the introduction of Article 27a (concerning exemptions for “serious and unforeseen circumstances”) has introduced significant elements of uncertainty. As pointed out by think-tank analyses, the possibility of discretionary modifications to the mechanism’s application undermines regulatory predictability (Rule of Law). For those managing logistics planning and long-term transport contracts, calculating the real impact of costs in real time becomes a high-risk economic exercise.
3. Severity of the Sanction Framework: Although the actual financial outlay for purchasing CBAM certificates will materialize starting in 2027 (covering 2026 emissions, with prices indexed to EU ETS market fluctuations), compliance obligations are immediate. Penalties for missing or partial declarations during the transition phase, combined with fines of up to 100 euros per missing certificate in the definitive regime, represent a severe insolvency risk for clients, with inevitable repercussions on the payment chain of transport services.

Legal Guidelines for Mitigating Logistics Risk

To safeguard operational continuity and financial integrity, transport and shipping companies must adopt a proactive and legally rigorous approach:

• Review of Customs Mandates: Where applicable and commercially viable, assess shifting from indirect representation to direct customs representation, leaving the formal and exclusive liability for CBAM compliance with the importer. In cases where indirect representation is unavoidable, it is imperative to include highly stringent indemnification and contractual guarantee clauses regarding the accuracy of emissions data provided by the client.
• Preventive Due Diligence on Customs Codes (CN/HS): Implement preventive verification systems—collaboratively between logistics and legal departments—aimed at mapping the product composition of cargoes right from the order quotation phase. Early identification of whether goods fall under CBAM annexes allows verification that the client holds an authorized declarant identification code before the cargo reaches EU borders.
• Traceability of “Reasonable Efforts”: In compliance with National Competent Authority guidelines, if third-party producers fail to provide actual emissions data (limiting the use of default values to what is strictly permitted), the logistics operator must ensure that the client irrefutably documents their unsuccessful attempts to retrieve the information. Demonstrating robust procedural due diligence is the only appropriate tool to mitigate administrative sanctions and prevent the precautionary seizure of goods.

Conclusion

CBAM is no longer a topic confined to corporate social responsibility or sustainability departments; it is a binding customs regulation redefining legal liabilities across the entire value chain. Facing Enforcement Risk with appropriate legal instruments is not just a measure to protect one’s balance sheet, but a strategic asset to ensure the efficiency, continuity, and stability of cross-border transport.
