CBAM Omnibus 2025: What Regulation EU 2025/2083 Changed and What Indian Exporters Must Update
Adopted in March 2025, the EU's CBAM Omnibus Regulation (EU 2025/2083) introduced five major updates to the original rules. A new small-importer threshold now exempts shipments under 50 tonnes. The rules around indirect emissions for aluminium have shifted, and anti-circumvention provisions for scrap are now much tighter. Plus, verification timelines have changed. While every Indian exporter should have updated their CBAM compliance programme by mid-2025, many are still lagging behind.
Key Takeaways
- Regulation EU 2025/2083, also known as the CBAM Omnibus package, was adopted by the European Parliament and Council in March 2025 as part of a broader regulatory simplification effort. It amends the original CBAM Regulation EU 2023/956 in several ways that directly affect Indian steel, aluminium, and fertiliser exporters. These amendments apply from January 2026, marking the start of the definitive period. This means that all CBAM declarations due from September 2027 onwards (which cover calendar year 2026 imports) must follow the new Omnibus rules.
- The most operationally significant change is a new de minimis threshold exempting small importers from the CBAM obligation. According to the Omnibus amendment, EU importers whose total CBAM-covered imports in a calendar year fall below 50 tonnes of net product weight are entirely exempt. This is meant to ease the administrative burden on small traders and occasional importers, such as European SMEs and individuals handling small quantities. For Indian exporters, this is good news. It means you no longer need to gather and provide complex embedded emission data to EU customers who fall below this 50-tonne mark.
- The indirect emission scope for aluminium was also revised. The original regulation included Scope 2 indirect electricity emissions in its calculation, reflecting the fact that electricity determines about 80 percent of a coal-smelter's total emission footprint. The Omnibus kept this rule but clarified exactly how to calculate these indirect emissions when a producer uses captive power versus grid electricity. It also specified exactly how Power Purchase Agreements (PPAs) and Renewable Energy Certificates (RECs) should be treated. This clarity resolves previous ambiguities that had led to wildly inconsistent CBAM declarations across the EU.
- Anti-circumvention provisions for aluminium scrap were significantly tightened. The original rules lacked clear provisions to stop secondary aluminium producers from claiming near-zero emissions when using pre-consumer scrap sourced from high-carbon primary smelters. The Omnibus added Article 7a, which requires pre-consumer scrap to carry the embedded emission factor of the primary production process it came from, rather than a default low value. This directly hits Indian secondary aluminium producers sourcing pre-consumer scrap from facilities like Vedanta's Jharsuguda or NALCO's Angul. Their CBAM calculations must now reflect the coal-heavy footprint of that primary scrap.
- The verification and declaration timeline has also shifted. The Omnibus extended the deadline for the first CBAM annual declaration 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. For Indian exporters, this simply means your EU customers have four extra months to file declarations for 2026 imports, giving your team more breathing room to establish proper data collection and verification chains. However, the definitive period still officially begins in January 2026.
- Finally, the Omnibus requires the European Commission to conduct a review of CBAM's functioning by 31 December 2028. Specifically, they will assess how CBAM interacts with domestic carbon pricing instruments like India's Carbon Credit Trading Scheme (CCTS). This review is the mechanism that will determine if the CCTS-CBAM Article 9 deduction provision (which allows carbon prices paid in India to reduce CBAM obligations) will be strengthened. Indian exporters need to watch this closely, as it will determine if CCTS compliance actually generates genuine CBAM cost offsets by 2029.
The EU's Omnibus regulatory simplification package of 2025 touched dozens of regulations in an effort to reduce administrative complexity across European green policy. CBAM was among the regulations amended, and while the changes were framed as simplification measures, several of them have substantive implications for the compliance programmes of non-EU exporters, including India's steel, aluminium, and fertiliser industries. Understanding exactly what changed, what it means operationally, and how your compliance team needs to adapt is essential. If your EU CBAM programme was designed around the original Regulation EU 2023/956 and hasn't been updated, you are likely out of compliance.
The five changes described above are the substantive amendments that Indian exporters need to incorporate into their systems today. There are also several minor administrative clarifications in the Omnibus that do not change the fundamental CBAM mechanics, such as updates to Registry operating procedures, changes to the declarant registration process, and revised guidance on reporting templates. Compliance teams should review the full Regulation EU 2025/2083 text for these details, but they generally won't require a material restructuring of your existing compliance programme.
The small-importer threshold: which EU customer relationships change
The 50-tonne de minimis threshold is the change with the broadest practical effect for an Indian exporter's commercial relationships. Across all CBAM-covered product categories, EU importers bringing in fewer than 50 tonnes of net product weight per calendar year are exempt from the CBAM declaration requirement. Consequently, they do not need to demand verified embedded emission data from their Indian suppliers. The immediate commercial question for Indian exporters is figuring out exactly how many of their EU customer accounts fall below this new threshold.
For large bulk commodity exporters, like Indian steel plants shipping 20,000 to 200,000 tonnes per year to major European service centres, the 50-tonne threshold is irrelevant. Every shipment is well above the mark, so CBAM compliance requirements are unchanged. However, this threshold is a gamechanger for exporters selling to mid-tier European distributors, specialist wholesalers, and small manufacturers. In the aluminium sector, this applies to many specialty alloy exporters. In fertiliser additives, it applies to niche agricultural input suppliers. In steel, it primarily benefits specialty steel and tube exporters selling small-lot products to European engineering SMEs.
| Change | Original Regulation (EU 2023/956) | Omnibus Amendment (EU 2025/2083) | India Exporter Impact |
|---|---|---|---|
| De minimis threshold | No threshold. All importers were required to file declarations. | EU importers below 50 t/year net weight are exempt from CBAM declarations. | Significantly reduces data provision obligations for Indian exporters selling to small EU buyers. |
| Aluminium Scope 2 methodology | Included, but the methodology for captive power vs grid vs PPA/REC treatment was ambiguous. | Clarified to use the actual emission factor of the verified electricity source. PPA/REC must demonstrate additionality. | Forces Indian smelters to choose between actual RE delivery documentation or the national GEF. RECs alone are insufficient. |
| Scrap anti-circumvention (Article 7a) | No explicit provision. Secondary producers could claim low embedded emissions regardless of the scrap source. | Pre-consumer scrap must now carry the emission factor of the original primary production process. | Indian secondary aluminium using pre-consumer scrap from coal-based primary smelters must update embedded emission calculations. |
| First declaration deadline | 31 May 2027 (covering 2026 imports). | 30 September 2027 (covering 2026 imports). | Indian exporters and their EU customers have 4 additional months to finalise verified emission data for 2026. |
| CBAM-domestic carbon pricing review | Contained a general Article 30 review mandate. | Specifically mandates a Commission review of Article 9 (carbon price deduction) by 31 December 2028. | CCTS-CBAM interaction will be formally reviewed by 2028, leading to a potential strengthening of the deduction mechanism. |
| CBAM Registry operating procedures | Contained initial registration requirements. | Updated authorised declarant renewal requirements and CBAM account management rules. | Administrative update. EU importers of Indian goods should confirm their Registry registration is up to date. |
The Article 7a scrap provision: who it affects in India's aluminium sector
Article 7a of the amended CBAM Regulation creates the most significant compliance headache for India's secondary aluminium producers. Before the Omnibus, a secondary aluminium producer purchasing machining chips, dross, or off-specification billets from Vedanta's Jharsuguda primary smelter could treat this pre-consumer scrap as a zero-emission input. They could claim the low embedded emission of secondary aluminium (0.5 to 0.8 tCO₂/t) for their final product because the scrap, regardless of origin, represented recovered material that avoided new primary production.
Article 7a closes this loophole. It requires that pre-consumer scrap carries forward the embedded emission factor of the original production process. A secondary producer using Jharsuguda pre-consumer scrap (which comes from a facility with roughly 16.5 tCO₂/t embedded emissions) must now calculate a weighted average embedded emission for its final product. This calculation must reflect both the coal-primary-sourced scrap's emission factor and the secondary melting electricity emission factor, weighted by the proportion of each in the final product's metal content. If a secondary producer uses 100 percent Jharsuguda pre-consumer scrap, the embedded emission of their final product will closely mirror the primary smelter's heavy footprint, completely erasing the secondary producer's low-carbon advantage.

The Omnibus clarification on PPA and REC treatment for aluminium Scope 2 and why it matters.
The original CBAM Regulation was notoriously ambiguous about whether an aluminium smelter purchasing RECs could use the low emission factor of that REC-attributed generation for Scope 2 purposes, or if they were forced to use the national grid average. The Omnibus clarifies this. The actual emission factor of the electricity physically consumed at the smelter is the relevant figure, subject to strict additionality requirements for any renewable attribution. A smelter purchasing RECs from existing renewable projects without additionality cannot use the renewable emission factor; it must use the national grid GEF. However, a smelter that has a physical PPA with new additionality-verified renewable capacity, accompanied by metered delivery, can use the actual renewable emission factor for the quantity of energy physically delivered. While this aligns CBAM's electricity treatment with the GHG Protocol's market-based accounting rules, it means that Indian smelters relying on legacy REC purchases to claim low Scope 2 emissions must urgently recalculate their compliance metrics.
Frequently Asked Questions
When does the Omnibus amendment apply? Does it affect 2025 imports or only 2026 onwards?
The Omnibus amendments officially apply from January 2026, marking the start of the definitive CBAM period. The transitional period (October 2023 to December 2025) operated entirely under the original Regulation EU 2023/956. CBAM declarations filed for the transitional period are not retroactively affected by the Omnibus. The first CBAM annual declaration, due 30 September 2027 covering 2026 imports, must apply the Omnibus-amended rules in full. Any embedded emission data Indian exporters have already provided to EU customers based on the old methodology should be reviewed against the Omnibus amendments and updated before the 2026 data is officially submitted.
Does the 50-tonne de minimis threshold apply per product category or across all CBAM goods combined?
The 50-tonne threshold applies to the total combined weight of all CBAM-covered goods imported by a single EU importer in a calendar year. It is not applied per category. For example, an EU importer buying 30 tonnes of steel billets and 25 tonnes of aluminium wire from India in 2026 has combined CBAM imports of 55 tonnes. Because they are above the threshold, they must file a CBAM declaration covering all those goods. Because this threshold applies at the importer level, Indian exporters cannot safely assume their EU customers are exempt without explicitly confirming the customer's total CBAM import volume across all global suppliers.
What does the mandated December 2028 review mean for the CCTS-CBAM Article 9 deduction?
Article 9 of the CBAM Regulation allows carbon prices paid in third countries, including India's CCTS, to reduce the net CBAM certificate obligation for exporters from those regions. The Omnibus mandates that the Commission conduct a specific review of this Article 9 deduction mechanism by December 2028. They will assess whether the domestic carbon pricing instruments of third countries meet the stringency and transparency requirements to justify a meaningful deduction. If the review concludes that India's CCTS is sufficiently robust (featuring verified MRV, active market pricing, and strict enforcement), it could recommend strengthening the deduction calculation. This would make CCTS compliance a direct and highly valuable tool for reducing CBAM costs by 2029.
