CBAM Explained: Impact on the Chemical Sector and Who Bears the Cost

What Is the CBAM?

The European Union’s Carbon Border Adjustment Mechanism (CBAM) is a policy designed to level the playing field between EU producers and foreign competitors. By imposing a carbon price on imported goods, the EU aims to prevent "carbon leakage"—where companies relocate production to countries with looser emissions rules.

Scope of the Mechanism

CBAM covers a range of sectors that are carbon‑intensive and have a high risk of leakage. In its definitive phase starting January 2026, the mechanism includes:

• Chemicals and fertilisers
• Steel and aluminium
• Cement
• Electricity generation

How the Tax Is Calculated

Importers must report the carbon intensity of their goods, measured in tonnes of CO₂e per unit. The CBAM price is calculated by:

1. Determining the EU allowance price for the relevant sector.
2. Subtracting any carbon credits the importer holds.
3. Applying the difference to the imported quantity.

For chemicals, the calculation takes into account the full life‑cycle emissions—from feedstock extraction to final product.

Who Pays the CBAM?

The responsibility for paying the CBAM falls on the importer, not the producer. Importers must:

• Submit an annual report detailing the carbon intensity of each imported batch.
• Pay the calculated carbon price to the customs authority.
• Maintain documentation to prove compliance.

However, the cost can ripple upstream. Manufacturers may pass the charge to importers through higher purchase prices, while distributors may adjust their margins. In practice, the financial burden is shared along the supply chain.

Implications for Chemical Companies

1. Supply Chain Transparency

Companies must map emissions across their supply chain to provide accurate data. This involves:

• Partnering with suppliers for emissions data.
• Implementing robust data capture systems.
• Regular audits to verify accuracy.

2. Product Innovation

Reducing the carbon intensity of products—through greener feedstocks, energy efficiency, or carbon capture—lowers CBAM exposure.

3. Strategic Sourcing

Shifting imports to regions with lower carbon footprints or higher carbon pricing can mitigate costs.

4. Financial Planning

Companies should model CBAM impacts in their budgeting and risk assessments. Options include hedging against carbon price volatility or incorporating CBAM costs into pricing strategies.

Compliance Checklist for Importers

1. Identify the CBAM classification for each product.
2. Collect emission data for each batch.
3. Calculate the carbon price using the latest EU allowance rates.
4. File the annual report and pay the tax on time.
5. Keep detailed records for at least five years.

Future Outlook

The CBAM is expected to evolve, with potential expansion to more sectors and tighter reporting requirements. Chemical companies that proactively address emissions and build data capabilities will be better positioned to navigate the new landscape.

In summary, the CBAM places the onus on importers to pay a carbon price that reflects the EU’s internal carbon cost. By understanding the mechanism, collaborating across the supply chain, and investing in low‑carbon technologies, the chemical industry can turn a regulatory challenge into an opportunity for innovation and competitiveness.
