2026 brought changes in customs regulations for importing goods into the EU. The requirements are no longer dictated by what happens at the border but require even more preparation in advance.
In this article, we will explain what ICS2, CBAM, and ESG mean; what changes will come into effect in 2026; and their practical value for all participants in the supply chain and trade with the EU.
New compliance rules in 2026
Three frameworks are being implemented in practice:
- ICS2 2026 requirements, which transform shipment data into security gates
- CBAM 2026 rules, which link imports to verified carbon reporting
- ESG Logistics Compliance, which increasingly links performance to corporate accountability
The result is simple: compliance can no longer be fixed at the border. It must be designed into the supply chain upstream.
What is the ICS2?
ICS2 (Import Control System 2) updates customs processes from a technical standpoint. And in practice, it introduces strategic changes to the management of import risks in the EU.
To avoid post-arrival inspections of goods, ICS2 requires the submission of preliminary cargo data earlier and more detailed, significantly cutting room for manual corrections. What is the impact?
- Errors are not carried over to the final arrival stage, but are detected upstream
- Delays in shipments can occur before the shipment reaches Europe
- Routing complexity becomes a compliance variable
ICS2 requirements for 2026
ICS2 came into force on April 1, 2025, and has significant changes in 2026:
- Mandatory submission of ENS via ICS2: All carriers and forwarders must submit an Electronic Entry Summary Declaration (ENS) to EU customs before crossing the border. The old ICS system will cease to function for this type of data.
- Transition period in Hungary: Until March 15, 2026, ENS can be submitted via the old ICS system and only via ICS2 after the deadline.
- Extension to road and rail transport: The new rules apply to all land transport, which requires a detailed cargo description (TN FEA codes, consignor/recipient data).
- Risk analysis: The data is used for a preliminary security assessment, allowing customs officers to stop suspicious cargo before it arrives at the border.
What’s the impact?
The updated ICS2 requirements create a logistics environment that requires enhanced scheduling, transit structure, and route consistency even more.
This is not just about moving cargo but about having a complete picture of the supply chain through real-time data at every level that accompanies the shipment. This is how compliance is stabilized.
In practice, companies are relying on the transparency of shipment planning: scheduling analytics, routing tools for custom needs, and live tracking of exceptions. All these slight but smart efforts help reduce the risk of data variance before departure.
What are the CBAM rules?
The CBAM (Carbon Border Adjustment Mechanism) entered its final operational phase on January 1, 2026. For importers, it is a key mechanism for ensuring compliance with trade rules within the framework of climate policy.
CBAM connects three elements that were previously separate, namely, production emissions, supplier transparency, and the total landed cost of EU imports.
CBAM requirements for 2026
Transition from test mode to full operation. Key must-knows in 2026:
- Financial responsibility: Importers will start to pay for their emissions by purchasing CBAM certificates, the price of which is linked to the carbon price in the EU Emissions Trading System (EU ETS).
- Annual reporting: Reporting is moving from quarterly to annual. The first full annual report must be submitted by 31 August 2027.
- Data simplification: While the use of supplier data is not mandatory, it is more cost-effective to provide actual data than to use the higher EU default values.
- Anti-circumvention: Enhanced reporting and traceability requirements are introduced.
What’s the impact?
What does this mean for planners and dispatchers? A new requirement in logistics operations. Trade is impossible without reliable emissions data. Suppliers and logistics providers that lack insight into the carbon footprint of different transport types only provide shippers and traders with uncertainty.
This uncertainty in carbon emissions leads to the untransparency and lack of clarity in reporting and, of course, freight pricing, contract stability, and supply planning.
Cargo owners and shippers will increasingly calculate potential emissions from the very start of production. Long before transport decisions are locked in. Delivery success will also depend on the carrier’s ability to clearly explain how different transport options influence overall emissions.
What is ESG logistics compliance?
In 2026, ESG (Environmental, Social, and Governance) is increasingly being directed towards the factual verification of sustainability claims.
The main goal of increased regulation is to clarify the following: Do actual supply chain solutions match the stated commitments?
ESG requirements for 2026
Shift from policy-building to implementation and enforcement. Main updates for 2026:
- CSRD (Corporate Sustainability Reporting Directive) expansion: More large companies are required to submit mandatory ESG reports under ESRS (European Sustainability Reporting Standards).
- External assurance: Sustainability data increasingly requires third-party verification.
- Double materiality: Companies must report both financial risks from ESG factors and their environmental/social impact.
- Supply chain due diligence: Stronger transparency requirements across suppliers and value chains.
- Board responsibility: Management and boards are directly accountable for ESG disclosures.
- Data alignment: Reported ESG metrics must match operational and emissions data.
What’s the impact?
From a logistics perspective, ESG impacts:
- Carrier and route selection
- Emission allocation by mode and distance
- Tracking between declared and actual supply chain behavior (e.g., schedules tracing and exceptions monitoring)
Shipment transparency becomes the foundation of supply chain management and customer service: execution visibility, tracking, and routing consistency.
Common field for ICS2, CBAM, and ESG
The challenge for international trade is not managing each regulation separately.
Their combined effect creates a system where:
- Poor shipment data can block cargo upstream
- Unclear sourcing increases landed cost through carbon exposure
- Inconsistent logistics execution undermines ESG credibility
EU import compliance in 2026 is evaluated across:
- Time (pre-arrival enforcement)
- Traceability (shipment transparency)
- Emissions accountability (carbon-linked cost exposure)
Timeline of EU customs compliance
Let’s discover when flexibility in your supply chain disappears stage by stage:
Before booking
Flexibility still exists, and you can adjust supplier selection, routing, and documentation structures.
Before departure
Here, the ICS2 submissions become binding, and any of the mistakes might lead to automated booking cancellation. There are fewer windows for manual correction.
During transit
At this stage, the compliance for CBAM and ESG is critical, as resolving mismatches becomes more expensive.
At the EU entry
By the time cargo reaches the EU border, most compliance outcomes have already been determined by earlier decisions — data submission under ICS2, emissions transparency under CBAM, and supply chain consistency under ESG.
What are the consequences?
1. Earlier decisions carry greater weight.
Supplier choice, routing structure, and documentation accuracy now define compliance stability.
2. Mistakes become more expensive over time.
Upstream data errors may lead to shipment holds, carbon cost exposure, or reputational risk.
3. Visibility becomes a control mechanism.
Real-time shipment tracking, emissions clarity, and route consistency are compliance safeguards.
In 2026, EU import control is not about reacting at the border. It is about controlling risk before departure.
To sum up
The EU is currently developing an import control system. As the parts of this system updated on ICS2, CBAM, and ESG have already highlighted requirements for improved data screening, emissions transparency, and traceability expectations for trade in 2026.
These are practical methods to assess supply chains on an early and more structured basis to avoid delays, documentation inconsistencies, and costly importer errors.

FAQ: EU Customs Rules 2026 (ICS2, CBAM, ESG)
1. What are the new EU customs rules in 2026?
The European Union is implementing new customs regulations, which will establish enforcement procedures through advanced cargo data screening (ICS2) and an operational carbon reporting system for imports (CBAM) and new supply chain transparency requirements for environmental, social, and governance (ESG) factors. Compliance is now evaluated before cargo arrives, not only at the border.
2. What is ICS2, and what does it require?
ICS2 (Import Control System 2) is the EU’s pre-arrival security and risk-screening system. It requires import shipment data to be submitted earlier and with greater detail, allowing customs authorities to assess risk before goods enter the EU.
3. Can ICS2 lead to refusal to load?
Yes. If ICS2 data is incomplete, inconsistent, or submitted incorrectly, shipments may be held or refused for loading before departure. Enforcement happens upstream, making data accuracy critical.
4. What data must be submitted under ICS2?
ICS2 requires detailed advance shipment information, which needs accurate HS codes and consignee and shipper details, routing and transport data, and safety/security elements. The process becomes increasingly difficult because errors become permanent after submission.
5. Does CBAM operate at full capacity during the year 2026?
The answer is yes, CBAM began its full operational phase on 1 January 2026, which marked the transition from transitional reporting to active compliance assessment for all covered imports.
6. What are the CBAM reporting obligations that importers must follow?
Importers of CBAM-covered goods must report verified emissions data that relates to their production activities. The requirement to report increases for carbon-intensive sectors is because organizations need to provide trustworthy emissions data from their suppliers.
7. Will CBAM increase EU import costs?
CBAM can increase total landed cost by introducing carbon-linked obligations based on emissions intensity. Suppliers who lack emissions transparency create two problems for businesses, which include unpredictable pricing and potential compliance violations.
8. Which goods are covered by CBAM in 2026?
CBAM applies to all carbon-intensive imports, which include iron and steel, aluminum and cement, fertilizers, electricity, and hydrogen. The sectors require the most stringent procedures for reporting and certification.
9. How do EU customs changes affect transit time and delays?
EU customs enforcement now happens earlier, so routing complexity, schedule deviations, or incorrect advance data can trigger shipment holds before arrival. Businesses use transit predictability to manage their compliance risk.
10. Is ESG becoming part of EU trade compliance?
ESG is not a customs formality, but it increasingly affects trade compliance risk. EU regulators and stakeholders expect supply chain traceability and consistency between reported sustainability claims and actual logistics execution.
