The EU’s carbon border tax entered its definitive phase in January 2026. Here’s what it means for your margin, your reporting, and your competitive position — and the five things to do this quarter.
This piece is the action guide we share with Indian exporters in covered sectors. It covers what CBAM actually is, what it costs in 2026 and what it will cost by 2030, and the five things to do this quarter regardless of what your buyer has asked you for so far.
What CBAM actually is, in one paragraph
CBAM is a carbon tariff on imports into the EU. For each tonne of CO₂-equivalent emissions embedded in a covered product, the EU importer must buy a CBAM certificate at a price linked to the EU Emissions Trading System (EU ETS) — essentially the same carbon price that EU producers in the same sector already pay. The mechanism is designed to prevent “carbon leakage” — EU producers losing market share to foreign competitors who don’t face equivalent carbon costs. From a buyer’s perspective, CBAM raises the landed cost of carbon-intensive imports. From a seller’s perspective, it makes embedded emissions a price-relevant attribute of your product.
Where we are now: the timeline
| Period | Phase | Financial obligation (% of full) |
| Oct 2023 – Dec 2025 | Transitional (reporting only) | 0% |
| 2026 | Definitive begins | 2.5% |
| 2027 | Definitive (ramp) | 5% |
| 2028 | Definitive (ramp) | 10% |
| 2029 | Definitive (ramp) | 22.5% |
| 2030 | Definitive (ramp) | 48.5% |
| 2031 | Definitive (ramp) | 61% |
| 2032 | Definitive (ramp) | 73.5% |
| 2033 | Definitive (ramp) | 86% |
| 2034 onward | Full implementation | 100% |
The financial percentage in the third column reflects the share of the full theoretical CBAM cost that EU importers actually pay, calibrated to the phase-out of free allocations under EU ETS. In 2026 the bite is small. By 2030 it’s serious. By 2034 it’s the full unmitigated cost.
The reporting obligation, however, is full and immediate. EU importers have to file quarterly CBAM reports during the transitional phase and annual CBAM declarations from 2026 onward. They cannot file accurately without data from you.
Sectors covered today — and what’s coming
Initial CBAM scope (already in force):
- Iron and steel, including downstream products (screws, bolts, structural steel)
- Aluminium, primary and certain semi-finished
- Cement
- Fertilisers (urea, ammonia)
- Electricity (cross-border imports)
- Hydrogen
Under active EU review for inclusion in the next expansion (likely 2027–2028):
- Organic chemicals
- Polymers (selected categories)
- Indirect emissions across more sectors
- Downstream goods (e.g. fabricated steel products)
If you export anything in the initial scope, CBAM is your problem now. If you export downstream products containing CBAM materials (e.g. machinery built from imported steel), it’s a problem you’ll inherit before 2030.
The financial impact: three worked examples
Three reference scenarios, all using an EU ETS price of approximately €80 per tonne CO₂ (early 2026 indicative; ETS prices have moved between €60 and €100 in the past two years).
Indian flat-rolled steel sold to Germany
| Line | Value |
| FOB Mumbai, per tonne steel | €700 |
| Embedded emissions (Indian blast-furnace average) | 2.2 tonnes CO₂e per tonne steel |
| EU ETS reference price | €80 per tonne CO₂ |
| Theoretical full CBAM cost (when 100% phased in) | 2.2 × €80 = €176 per tonne steel (~25% of FOB) |
| CBAM cost in 2026 (2.5% factor) | €4.40 per tonne steel (~0.6% of FOB) |
| CBAM cost in 2030 (48.5% factor) | €85.40 per tonne steel (~12% of FOB) |
| CBAM cost in 2034 (100% factor) | €176 per tonne steel (~25% of FOB) |
Indian primary aluminium sold to Italy
| Line | Value |
| FOB Mundra, per tonne aluminium | €2,200 |
| Embedded emissions (coal-grid Indian smelter average) | 16 tonnes CO₂e per tonne aluminium |
| EU ETS reference price | €80 per tonne CO₂ |
| Theoretical full CBAM cost (when 100% phased in) | 16 × €80 = €1,280 per tonne aluminium (~58% of FOB) |
| CBAM cost in 2026 (2.5% factor) | €32 per tonne (~1.5% of FOB) |
| CBAM cost in 2030 (48.5% factor) | €621 per tonne (~28% of FOB) |
| CBAM cost in 2034 (100% factor) | €1,280 per tonne (~58% of FOB) |
The aluminium case is the most extreme of the three. Indian aluminium is largely produced from coal-fired electricity, with embedded emissions well above the EU benchmark. Without rapid decarbonisation or sourcing changes, exporters in this category face a structural cost disadvantage by 2030.
Indian cement sold to a Mediterranean buyer
| Line | Value |
| FOB, per tonne cement | €85 |
| Embedded emissions (Indian average, OPC) | 0.8 tonnes CO₂e per tonne cement |
| EU ETS reference price | €80 per tonne CO₂ |
| Theoretical full CBAM cost (when 100% phased in) | 0.8 × €80 = €64 per tonne cement (~75% of FOB) |
| CBAM cost in 2026 (2.5% factor) | €1.60 per tonne (~2% of FOB) |
| CBAM cost in 2030 (48.5% factor) | €31 per tonne (~37% of FOB) |
| CBAM cost in 2034 (100% factor) | €64 per tonne (~75% of FOB) |
Cement is the most existentially affected category. By 2034, the full CBAM cost approaches the FOB price itself. Indian cement exports to the EU at full CBAM are not commercially viable without major reductions in clinker emissions or substitution with blended cements.
What changes in the buyer-supplier conversation
Until now, your EU buyer has cared about price, quality, lead time, and certifications. From 2026 onward, embedded emissions joins that list — and not as a soft preference. It’s a hard cost line on his import bill.
Three concrete shifts in conversation we’re already seeing:
- Buyers are asking for installation-specific verified emissions data, not industry defaults. The EU Commission’s default values for non-EU producers are deliberately punitive — typically 1.5–2× actual best-case emissions for the same product. Suppliers who can provide actual verified data save buyers money. Suppliers who can’t, lose share.
- Long-term contract pricing is including CBAM escalators. Multi-year EU offtake contracts now routinely include clauses adjusting for CBAM cost rises year by year, with the supplier expected to absorb a defined share of the increase.
- Buyer-side CBAM declarants are scrutinising entire supplier portfolios. EU importers above 50 tonnes annual covered-good imports must register as authorised CBAM declarants and bear personal liability for the accuracy of declarations. They cannot rely on supplier good faith — they need verified data, ideally audited.
The Indian carbon price exemption
CBAM allows EU importers to deduct any explicit carbon price the producer has already paid in the country of origin. India launched its Carbon Credit Trading Scheme (CCTS) in 2024 with phased coverage of energy-intensive sectors.
In principle, this is a major potential offset. In practice as of early 2026:
- The Indian carbon price under CCTS is materially lower than the EU ETS reference price.
- Coverage is being phased in sector by sector; not all CBAM-relevant Indian producers are yet captured under CCTS.
- Documentation requirements for the offset are demanding — exporters need verified evidence of the specific carbon price paid, not just sector-level participation.
This area will evolve significantly between 2026 and 2030. The trajectory matters: if Indian carbon prices rise toward EU levels (or India introduces a CBAM-equivalent of its own), the offset becomes meaningful. If they don’t, Indian producers carry the full CBAM cost on top of any domestic carbon obligations.
The five things to do this quarter
1. Measure your actual installation emissions
If you’re using EU default values for emissions data, you’re losing money for your buyers — and they will eventually find a supplier who isn’t. Engage a verifier to measure and certify your actual per-tonne emissions for each covered product line.
Practical first step: identify a credible third-party verifier accredited under the EU’s Implementing Regulation. The Bureau of Energy Efficiency, NABCB-accredited certifiers, and several international agencies (TÜV, DNV, SGS) are active in India.
2. Build an emissions data system per shipment
CBAM data is reported per shipment, not annually. You need a system that ties every export consignment to its installation, production batch, and verified per-tonne emissions.
This is operational work, not a one-off audit. The system has to feed your sales documentation routinely. Suppliers who can deliver this data alongside the commercial invoice — without their buyer asking — will win share.
3. Engage your buyers on multi-year CBAM clauses
If your contracts run beyond 2026, the CBAM cost ramp will affect both sides. Better to address it explicitly now than discover the impact at contract renewal in 2028. Two questions to raise with major buyers:
- How are they planning to share the CBAM cost increase between supplier price and their margin?
- Would they prefer a longer-term commitment in exchange for a defined emissions-improvement trajectory from your end?
4. Map your decarbonisation options
Even modest emissions reductions translate directly into CBAM cost savings — for your buyer in 2026, more for them in 2030, and increasingly for you as the cost gets shared back. Areas worth costing out:
- Renewable electricity sourcing (PPA contracts, captive solar)
- Energy efficiency retrofits in your most carbon-intensive process steps
- Substitution of inputs (e.g. blended cements, recycled aluminium feed, scrap-based steel)
- Process changes (electric arc furnace where viable, alternative reductants)
You don’t need a complete decarbonisation strategy in 2026. You need a credible pathway you can show buyers, with quantified milestones.
5. Document your Indian carbon price exposure
If your facility is covered under CCTS or pays any other explicit Indian carbon price, document it carefully — emission allowances purchased, rates paid, time periods covered. Even if the offset against CBAM is small in 2026, the documentation infrastructure you build now will pay off as Indian carbon prices rise.
Five common misconceptions
- “CBAM is the EU’s problem, not mine.” The financial obligation sits with the EU importer, but the cost is passed back through procurement decisions. By 2028, suppliers without verified emissions data will be uncompetitive on price even if their FOB looks identical.
- “It’s only 2.5% of the full cost in 2026, so I have time.” The cost ramps to ~50% by 2030 and 100% by 2034. Building the emissions measurement and reporting infrastructure takes 12–18 months. Start now.
- “My buyer hasn’t asked for actual emissions data, so we’re fine.” The reporting obligation on EU importers is full from 2026. They will ask. The earlier you have the data ready, the stronger your competitive position.
- “Indian carbon prices will offset everything.” Possibly true by the late 2020s, definitely not true today. Plan for the worst case where your offset is small, and treat any larger offset as upside.
- “CBAM only matters for big exporters.” Small exporters face the same per-tonne cost. The fixed costs of measurement and verification are higher per tonne for smaller producers — meaning small exporters often face a worse competitive position, not a better one.
The competitive opportunity
CBAM creates a structural pricing advantage for cleaner producers. An Indian steel mill with verified emissions of 1.6 tonnes CO₂/tonne steel (achievable with electric arc furnace + scrap feed + renewable electricity) faces materially lower CBAM cost than the 2.2-tonne industry average — even after the 2030 ramp.
For exporters who invest in measurement, verification, and decarbonisation early, CBAM is not a headwind. It’s a moat. Cleaner producers will systematically take share from dirtier ones across every CBAM-covered category between now and 2034.
The exporters who treat CBAM as a compliance burden will lose share. The exporters who treat it as a pricing advantage will win it.
