CBAM, the European Union’s Carbon Border Adjustment Mechanism, entered its definitive phase on 1 January 2026. It places a carbon-related obligation on EU imports of selected emissions-intensive goods. For Indian producers, the direct legal duty usually sits with the EU importer or its customs representative, but exporters must supply credible emissions data and may face new cost and contract pressure.
What CBAM does in 2026
The mechanism links the carbon cost of covered imports with the EU Emissions Trading System. An authorised EU declarant reports the embedded emissions in imported goods and surrenders the required certificates. The certificate price follows the EU ETS allowance price under the applicable rules.
The European Commission’s definitive-regime guidance says the system applies from 1 January 2026. It also explains the 50-tonne single mass-based threshold for covered goods and the duties of authorised declarants.
A carbon price already paid in the country of origin may reduce the number of certificates that must be surrendered when the required proof exists. Therefore, evidence and contract terms matter as much as headline carbon prices.
Goods currently covered
The definitive regime covers selected goods in cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen. Coverage depends on customs codes and the legal rules, not on a broad product label alone.
Exporters should map each product to the correct code and check whether processing changes the treatment. They should also identify the installation where the goods were made and the emissions data needed for the EU declaration.
The official CBAM Regulation, EU 2023/956 remains the core legal source. The European Commission also publishes implementing rules, sector guidance, and updated default values.
How the cost is calculated
The charge is based on embedded greenhouse-gas emissions in covered imports. Actual emissions data may be used when it meets the method and verification rules. Default values may apply in defined cases.
In practice, EU importers buy certificates from their national authority. They then surrender the amount linked to the emissions in their annual declaration, subject to the rules and any eligible deduction for a carbon price paid abroad.
The result is not a fixed customs tariff. It changes with embedded emissions, EU ETS prices, free-allocation phase-down rules, and any valid foreign carbon-price deduction. As a result, two similar products can face different exposure.
Why CBAM matters for Indian exporters
For example, India supplies the EU with products from several covered sectors, including iron, steel, and aluminium. Export impact will vary by product, plant, emissions intensity, customer contract, and the share of sales sent to Europe.
The first task is data readiness. EU buyers may ask for plant-level emissions data, production routes, energy inputs, and third-party verification. Weak data can lead to defaults, delays, price disputes, or lost business.
Next comes commercial allocation. Contracts should state who provides data, who bears certificate cost, and what happens if rules or prices change. Exporters should also align customs, sustainability, finance, and sales teams.
Green steel and aluminium strategy
Moreover, lower embedded emissions can improve an exporter’s position. Steel producers may examine energy efficiency, scrap use, cleaner power, process change, and low-emission fuels. Aluminium producers may focus on electricity sourcing, smelter efficiency, recycled metal, and traceable inputs.
However, each measure needs verified results. A renewable-energy certificate or corporate claim may not automatically meet the legal accounting method. Firms should check the specific CBAM rules before treating an investment as a compliance benefit.

CBAM data and verification workflow
Start with the product and customs code. Then identify the installation, production route, direct emissions, and any indirect-emissions fields required by the current rules. Keep source records for fuel, power, output, and process data.
Next, assign clear owners for data collection and review. Build controls for unit conversion, boundary changes, missing values, and version history. Meanwhile, coordinate with the EU customer so the format and deadline are clear.
Verification adds another layer. Producers should confirm which data must be checked, who may verify it, and when the report is due. The European Commission maintains a dedicated verification information page with current guidance and rules.
Trade and policy questions
The mechanism aims to address carbon leakage by aligning the treatment of covered imports with EU production. Yet exporters and governments continue to debate fairness, development impact, methods, and compatibility with trade rules.
India and the EU may also discuss carbon measures through trade and climate channels. Businesses should not assume that a political dialogue removes a legal duty. They should rely on enacted text and official guidance for each shipment.
Carbon pricing is also developing in India. Our guide to cap-and-trade and carbon markets explains how prices, allowances, and credits differ.
What exporters should do now
First, screen all EU-bound products against the covered codes. Second, map data gaps by plant and production route. Third, agree with EU customers on responsibilities, timelines, and cost sharing.
After that, test the calculation with realistic EU ETS price scenarios. Compare the cost of data improvement and emissions cuts with likely commercial exposure. Avoid using one average across plants when the rules require more detail.
Finally, monitor official updates. Guidance, default values, verification rules, and operational dates can change. Legal and technical advisers should review material decisions.
A practical India response
CBAM is both a compliance issue and an industrial strategy signal. Indian exporters that improve data, efficiency, clean power, and customer coordination may reduce risk and compete for lower-carbon demand.
The mechanism does not create the same outcome for every firm. Exposure depends on what is sold, how it is made, and how the contract works. A disciplined response combines legal checks, emissions measurement, plant investment, and trade planning.
