CBAM Omnibus 2025: What Regulation EU 2025/2083 Changed and What Indian Exporters Must Update Today
Adopted in October 2025, the EU's CBAM Omnibus Regulation (EU 2025/2083) introduced major updates to the rules that actively govern the 2026 definitive phase. A new small-importer threshold now exempts EU importers importing under 50 tonnes annually (excluding electricity and hydrogen). Additionally, the rules around indirect emissions for aluminium have shifted. While every Indian exporter should have updated their CBAM compliance programme by mid-2025, many are facing declaration failures in 2026 due to outdated methodologies.
Key Takeaways
- Regulation EU 2025/2083 (the CBAM Omnibus) amended the original EU 2023/956 rules. These amendments apply to the active 2026 definitive period. All CBAM declarations due from September 2027 onwards (covering CY 2026 imports) must follow these new rules.
- The most operationally significant change is a new de minimis threshold exempting small EU importers (below 50 tonnes of net product weight per year) from the CBAM obligation. Indian exporters selling to small EU buyers no longer need to provide complex embedded emission data for those accounts.
- The indirect emission scope for aluminium was clarified regarding how to treat Power Purchase Agreements (PPAs) and Renewable Energy Certificates (RECs). PPA/RECs must now strictly demonstrate additionality to use the renewable emission factor, resolving previous ambiguities that led to inconsistent declarations.
- The deadline for the first CBAM annual definitive declaration was extended from 31 May 2027 to 30 September 2027. This aligns with the EU's fiscal year and gives importers more time to obtain verified data from third-country exporters.
- The Omnibus requires the European Commission to conduct a review of CBAM's functioning by 31 December 2028, specifically assessing how CBAM interacts with domestic instruments like India's CCTS. This will determine if the Article 9 deduction provision is strengthened by 2029.
The EU's Omnibus regulatory simplification package of 2025 was framed as an administrative cleanup, but for Indian exporters, it altered fundamental compliance mechanics. The changes described above are substantive amendments that dictate how the active 2026 definitive phase operates. If your EU CBAM programme was designed around the original Regulation EU 2023/956 and hasn't been updated, your 2026 data collection is out of compliance.
The small-importer threshold: which EU customer relationships change
The 50-tonne de minimis threshold has the broadest practical effect. Across all CBAM-covered product categories (excluding electricity and hydrogen), EU importers bringing in fewer than 50 tonnes of net product weight per calendar year are exempt. Consequently, they do not need to demand verified embedded emission data from their Indian suppliers.
For large bulk exporters (e.g., steel plants shipping 20,000 to 200,000 tonnes per year), this threshold is irrelevant. Every shipment is well above the mark. However, this is a gamechanger for exporters selling to mid-tier European distributors, specialty alloy exporters, and small manufacturers. The immediate commercial action for Indian CFOs is auditing EU customer accounts to determine exactly which buyers fall below this new threshold across their total global imports.
CBAM Omnibus EU 2025/2083: Substantive Changes for Indian Exporters (Oct 2026)
| Change | Original Regulation (EU 2023/956) | Omnibus Amendment (EU 2025/2083) | India Exporter Impact |
|---|---|---|---|
| De minimis threshold | No threshold. All importers required to file declarations. | EU importers below 50 t/year net weight are exempt (excludes electricity & hydrogen). | Significantly reduces data provision obligations for exporters selling to small EU buyers. |
| Aluminium Scope 2 methodology | Included, but PPA vs grid vs REC treatment was ambiguous. | Clarified: PPA/REC must demonstrate strict additionality to use the renewable emission factor. | Forces Indian smelters to prove actual RE delivery additionality, or default to the national grid GEF. |
| First declaration deadline | 31 May 2027 (covering 2026 imports). | 30 September 2027 (covering 2026 imports). | Exporters and EU customers have 4 extra months to finalise verified emission data for 2026. |
| CBAM-CCTS Review | General Article 30 review mandate. | Mandates specific Commission review of Article 9 (carbon price deduction) by 31 December 2028. | CCTS-CBAM interaction formally reviewed by 2028, potentially strengthening the deduction mechanism. |
The Omnibus clarification on PPA and REC treatment for aluminium Scope 2.
The Omnibus clarified exactly how a smelter purchasing RECs can use a low emission factor for Scope 2. The actual emission factor of the electricity physically consumed is the relevant figure, subject to strict additionality requirements. A smelter purchasing RECs from existing, non-additional renewable projects must use the national grid GEF. However, a smelter with a physical PPA tied to new additionality-verified capacity can use the actual renewable emission factor. Indian smelters relying on legacy REC purchases to claim low Scope 2 emissions must urgently recalculate their 2026 compliance metrics.
Frequently Asked Questions
When does the Omnibus amendment apply? Does it affect 2025 imports?
The Omnibus amendments actively govern the definitive period starting January 2026. Transitional period reports (Oct 2023 to Dec 2025) operated under the original regulation. The first CBAM annual declaration, due 30 September 2027 and covering CY 2026 imports, must apply the Omnibus-amended rules in full.
Does the 50-tonne de minimis apply per product category or combined?
It applies to the total combined weight of all CBAM-covered goods imported by a single EU importer in a calendar year. If an importer buys 30 tonnes of steel and 25 tonnes of aluminium from India, their combined volume is 55 tonnes. They are above the threshold and must file. Because this applies at the importer level, Indian exporters must confirm their EU customers' total global CBAM import volume. Note that electricity and hydrogen are excluded from this exemption and must always be declared.
What does the mandated December 2028 review mean for the CCTS-CBAM Article 9 deduction?
The Commission will assess whether India's active CCTS meets stringency requirements to justify meaningful CBAM certificate reduction under Article 9. If the CCTS is found sufficiently robust (verified MRV, active market pricing), the review could recommend strengthening the deduction calculation, making CCTS compliance highly valuable for CBAM reduction by 2029.
