Is CBAM Just Another Tariff? What Every Importer Needs to Know in 2026

CBAM is not a Tariff – Here’s Why

When CBAM came into force, many importers assumed it was simply another customs charge. It isn’t. And treating it like a standard tariff could cost your business far more than expected.

A tariff is usually a fixed duty based on the value, quantity, or customs classification of imported goods. CBAM, by contrast, is a carbon cost. It places a price on the greenhouse gas emissions embedded in certain imported goods, which means the final cost depends not only on what the product is, but also on how and where it was made.

That is a major shift for importers. Two identical steel products can attract very different CBAM costs if they were produced in factories with different emissions intensity. In other words, CBAM turns supplier carbon data into a real commercial issue.

What makes CBAM different ? 

CBAM is not designed to replace customs duties, anti-dumping duties, VAT, or any other import charge. It sits on top of them. That means importers may face both traditional border costs and an additional carbon-based cost on the same shipment.

This is why CBAM should be treated as part of your landed cost model, not just as a compliance formality. If it is ignored, margins can be overstated, pricing can be inaccurate, and supplier negotiations may miss a major cost driver.

How CBAM cost is calculated

CBAM cost is driven by embedded emissions in the imported goods. In practical terms, the calculation depends on – 

• The emissions associated with the product.
• The country and production method used.
• Whether the supplier can provide verified actual emissions data.
• Whether any carbon price has already been paid in the country of origin and can be claimed under the rules.

If you do not have verified emissions data from your supplier, EU rules can require you to rely on default values. In many cases, those default values are less favourable than supplier-specific actual data, which can increase your exposure.

That is why emissions data is not just a sustainability issue anymore. It is a pricing, sourcing, and procurement issue.

Why do suppliers matter so much? 

Under CBAM, your cost exposure is directly linked to the quality of the data your supplier gives you. If the supplier cannot provide accurate, verified emissions information, you may be forced to use defaults that may not reflect the true carbon intensity of the product.

This creates a new commercial pressure point. Importers now need to ask suppliers questions that were rarely asked before – 

• What are your product-level embedded emissions?
• Can these emissions be verified?
• What methodology was used?
• Is there carbon pricing already paid in the origin country?

For some businesses, this will lead to better supplier transparency. For others, it may trigger a rethink of sourcing decisions altogether.

Who needs to pay attention? 

CBAM applies to certain carbon-intensive goods, including steel, aluminium, cement, fertilisers, hydrogen, and electricity. If your imports are within scope and your annual volume crosses the relevant threshold, you may need to register, report emissions, and eventually purchase and surrender CBAM certificates.

Even if your business is not yet in full payment mode, you should still start tracking now. The reason is simple: CBAM reporting and cost planning are connected. If you wait until the payment deadline, you may already have months of avoidable exposure built up.

Why does the first year matter? 

Many businesses make the mistake of treating CBAM as a future problem. It is not. The earlier reporting phase is exactly when companies should be building internal systems, collecting supplier data, and estimating exposure.

The first surrender and payment deadline for 2026 imports is later, but the real work starts much earlier. If you do not capture the right data now, you will struggle later when costs need to be reported, accrued, and passed through to customers.

For finance teams, that means CBAM should be built into forecasting and landed cost calculations. For sales teams, it affects quoting. For procurement teams, it affects supplier selection. For compliance teams, it affects reporting accuracy and risk.

What Irish importers should do now

If you are importing CBAM-covered goods into Ireland, the sensible next steps are:

1. Check whether you are in scope
   Review your annual import volumes and check whether your goods fall within CBAM categories.
2. Ask suppliers for emissions data now
   Do not wait until reporting becomes urgent. The earlier you start, the better your chance of getting usable data.
3. Build CBAM into pricing and margin models
   If CBAM is likely to affect your costs, it should be reflected in sales pricing and procurement decisions.
4. Review contracts and supplier terms
   If emissions data is missing or unreliable, you may need to revisit commercial terms.
5. Get internal ownership clear
   CBAM is not only a compliance issue. It affects finance, customs, procurement, sales, and sustainability.

The Bigger Picture

CBAM is more than a border rule. It is a signal of where trade policy is heading: toward carbon transparency, emissions accountability, and data-driven import compliance.

Businesses that understand this early can reduce exposure, improve supplier negotiations, and protect margins. Businesses that ignore it may end up paying more than they expected, and too late to change course.

CBAM is more than another tariff; it is a carbon cost, and businesses that recognise this early will be better positioned to manage risk and protect margins.
