Old Kolkata traders remember octroi, the tax charged when goods crossed a city boundary. Europe has built a modern version, and it does not tax weight or value. It taxes the carbon released while your metal was made. This is the EU Carbon Border Adjustment Mechanism, or CBAM, and in 2026 it moved from reporting to real money.
If you export steel, aluminium, fertiliser, cement or products made from them to Europe, or sell to someone who does, this guide is for you. It explains how CBAM works, what the certificate price is, which dates matter and what an Indian manufacturer can do now.
A note on accuracy: CBAM rules have been amended several times, and some dates differ between sources. We flag those below. Always confirm with the European Commission’s CBAM pages before you file anything.
The EU makes its own factories pay for carbon through the Emissions Trading System. Without a border charge, a European buyer could simply import the same metal from a country with no carbon price, and the factory would move abroad. This is called carbon leakage. CBAM closes the gap by making importers pay the same carbon price on the emissions locked into imported goods.
Think of a toll gate that weighs not your truck but your chimney. The cleaner your production, the smaller the bill.
| Period | What applies |
|---|---|
| October 2023 to December 2025 | Transitional phase. Importers only reported emissions. No payment. |
| 1 January 2026 | Definitive phase begins. Authorised declarants must buy CBAM certificates for emissions in imports. |
| 2026 | Certificate price is set from the EU ETS average, published by the Commission. Purchases open in February 2027. |
| 2027 | First annual declaration and surrender. Sources give 31 May 2027 and 30 September 2027. Verify the current date. |
This difference matters. A missed deadline means penalties, and the penalty can cost more than the carbon itself.
The CBAM certificate price follows the EU carbon market. Quarterly prices published so far for 2026 are:
The price rose about 9% from Q2 to Q3. For an importer, every tonne of embedded carbon in your goods costs roughly that much. A tonne of steel with 2 tonnes of embedded CO2 would carry about €165 at the Q3 price, before any deduction for a carbon price already paid in the country of origin. That figure is an illustration, not a quote, since actual emissions depend on the plant and the process.
The core list is iron and steel, aluminium, cement, fertilisers, electricity and hydrogen. The Commission has moved to bring in more downstream goods made from these metals, such as fasteners, wire, structures and certain machinery parts. Check your customs code. If your product falls in a covered code, or is made of covered material, your European customer will start asking for emissions data.
Copper itself is not at the heart of the scheme today. But a copper manufacturer that also buys steel or aluminium inputs, or sells copper-bearing products with steel or aluminium parts, can be pulled in through the supply chain. SMARTE advises treating this as a watch item, not a closed one.
The EU is a major export market for Indian steel and aluminium. India’s power grid still leans heavily on coal, so many Indian plants have higher embedded emissions per tonne than European or some Middle Eastern rivals. Under CBAM, that gap becomes a price. Indian trade bodies and the government have objected to the scheme, and talks continue, but exporters cannot plan around hope.
Chanakya warned against fighting a neighbour’s gate with arguments alone. Build the road that avoids it. In CBAM terms, the road is verified low-carbon production and clean data.
The most important lever is step one. If you cannot prove your emissions, the EU applies default values, which are usually higher than real values. Good data can cut the bill. Bad data raises it.
Take a tonne of primary aluminium. Smelting is power hungry, so most of its carbon comes from electricity. Suppose a coal-powered smelter reports 14 tonnes of embedded CO2 per tonne of metal, and a hydro-powered smelter reports 4. At the Q3 certificate price of €82.32, the first carries about €1,152 of carbon cost before deductions and the second about €329. The numbers are illustrative, since real values vary by plant, but the gap of roughly €820 a tonne is larger than many exporters’ entire margin.
The lesson is that where your power comes from can matter as much as what you charge. A buyer in Rotterdam will look at two quotes with the same price and choose the one with the smaller carbon line.
A copper products maker that uses steel fixtures, aluminium frames or packaging in finished goods should ask its European customers one question this month: do any of our products, or parts, fall under a CBAM customs code? A short written answer from the customer is worth more than a month of guessing. If the answer is yes, start the data work. If the answer is no, record the reply and review it each quarter, because the list of covered goods has been growing.
There is also an opportunity. Manufacturers that can show clean, verified production data stand out in a market where most competitors cannot. In the language of brand, carbon proof is a trust signal, much as ISO marks were a generation ago.
Keep these in one folder, updated each quarter. When a European buyer emails on a Friday afternoon asking for figures by Monday, the exporter with a ready folder wins the order.
| Path | What happens | Best response |
|---|---|---|
| Rules tighten | More downstream goods and indirect emissions are added | Get data for the whole product, not only the metal |
| Rules ease | Pressure from trading partners softens details or timing | Keep the data work. Customers will still ask for it |
| Rules spread | Other countries copy the EU model | Treat carbon data as a permanent part of the product |
Whichever path comes, the exporters with clean data and a verified low-carbon claim will win orders that others lose. Carbon is becoming a spec, like tensile strength or purity.
The EU Carbon Border Adjustment Mechanism makes importers pay for the carbon emitted in making certain goods, so they face the same carbon price as European producers.
The definitive phase began on 1 January 2026. Certificate purchases open in February 2027, and the first annual declaration falls in 2027.
It follows the EU ETS average. Published 2026 quarterly prices were €75.36 in Q1, €75.28 in Q2 and €82.32 in Q3.
Copper is not a core covered good today, but steel and aluminium content in products can bring copper manufacturers into scope through the supply chain.
Measure and verify emissions, use cleaner power and recycled inputs where provable, and give European customers accurate data rather than default values.
CBAM is not a European curiosity. It is a template for how the world will price metal in future, with carbon sitting beside price, purity and delivery on the order sheet. The cost is real, the dates are close and the best response is data. If you want a CBAM readiness check for your product list, talk to SMARTE.
Certificate prices and the declaration date range come from secondary market sources gathered during research. Verify them against the Commission before use.
