Key Deadlines Manufacturers Outside the EU Must Know

Introduction: Why CBAM Deadlines Matter for Your Business

The EU Carbon Border Adjustment Mechanism(CBAM) is no longer a future regulation—it's active, and non-compliance carries financial consequences. If you manufacture cement, steel, aluminum, fertilizers, hydrogen, or electricity outside the EU and export these goods to European markets, understanding CBAM deadlines is critical to maintaining market access.

From January 2026 onwards, the CBAM transitions from its transitional reporting phase to the definitive phase, where financial obligations begin. Missing deadlines can result in penalties ranging from €10 to €50 per tonne of unreported emissions—costs that quickly add up for high-volume exporters.

This guide outlines the key deadlines manufacturers must know, the reporting requirements at each stage, and actionable steps to ensure compliance.


Understanding the CBAM Timeline: Transitional vs.Definitive Phase

Transitional Phase (1 October 2023 – 31 December 2025)

During this phase, EU importers of CBAM goods must submit quarterly reports on embedded emissions. As a manufacturer, you are responsible for providing accurate emissions data to your EU importers.

Key characteristics:

Definitive Phase (Starting 1 January 2026)

From 2026, EU importers must purchase and surrender CBAM certificates corresponding to the embedded emissions of imported goods. Manufacturers who fail to provide verified emissions data will be subject to default emission values—typically higher than actual emissions, resulting in higher costs for your EU customers.

What Manufacturers Must Do Before Each Deadline

1. Monitor Embedded Emissions (Direct + Indirect)

You must track:

Accepted methodologies:

2. Communicate Data to EU Importers Quarterly

Your EU customers (importers) must submit quarterly reports. You should provide them with:

Recommended tool: Use the European Commission's voluntary communication template(Excel-based) to standardize data exchange.

3. Prepare for Verification (Starting 2026)

From 2026, third-party verificationbecomes mandatory. Accredited verifiers will assess your emissions monitoring methodology and validate your reported data.

Steps to prepare:

  1. Align your monitoring methodology with EU MRV rules (Implementing Regulation EU 2023/1773)
  2. Document your processes: Maintain records of fuel consumption, electricity use, and calculation factors
  3. Identify an accredited verifier in your jurisdiction or the EU
  4. Conduct internal audits to ensure data accuracy before external verification

Penalty Structure: What Happens If You Miss a Deadline?

Transitional Phase (2023-2025): Reporting Penalties

If your EU importer fails to submit a quarterly report due to missing data from you, they face penalties of €10 to €50 per tonne of unreported goods. While the penalty is levied on the importer, repeated non-compliance can damage your business relationship and may result in importers seeking alternative suppliers.

Definitive Phase (2026+): Financial Consequences

From 2026, if you do not provide verified emissions data, your EU customers will be assigned default emission values. These are set at the 90th percentile of global emissions intensity for each product category—meaning they are significantly higher than the actual emissions of most installations.

Example:

For a manufacturer exporting 10,000 tonnes annually, this results in €800,000 in avoidable costs.
