EU CBAM and carbon reporting for metal parts

What CBAM changes for a metal part

The Carbon Border Adjustment Mechanism puts a carbon cost on certain carbon intensive goods entering the EU. It is designed to sit alongside the EU emissions trading system, so that an importer of steel or aluminium does not get an advantage over an EU producer that already pays for its emissions.

For a buyer, the change is procedural before it is financial. The importer, or an indirect customs representative, becomes the declarant. The declarant needs the embedded emissions of the goods, a verification arrangement and an annual declaration. The obligation follows the import, not the contract.

The transitional period was about reporting. The definitive regime adds the financial element, with the exact treatment set by the regulation and the implementing acts. Because those instruments are updated, the practical rule is to check the current text and the current guidance rather than rely on a summary from last year.

Is the part in scope? Start with the code

CBAM is organised by CN code. The regulation lists the goods in scope, and the list is the scope test. A part that looks like steel to an engineer is not automatically a CBAM good, and a part that looks finished may still be caught if its code is listed.

The covered sectors include iron and steel, aluminium, cement, fertilisers, electricity and hydrogen. Within iron and steel and aluminium, the listed codes cover a range of semi finished and finished goods, with some downstream products added over time.

Start with the classification you already use for duty. Then check the code against the current CBAM list. If the code is listed, the good is in scope and the emissions question follows. If the code is not listed, keep the check on file, because the list can change and a reclassification can bring a part into scope.

There is also an importer level mass threshold. Confirm the current figure and how it is calculated, because it can remove small importers from the obligation without removing the need to know the data.

Direct and indirect emissions

Direct emissions come from the production process at the installation: fuel burned, process reactions and any on site generation of heat or electricity. Indirect emissions come from the electricity consumed in producing the goods.

The two are reported separately because the regulation treats them differently, and because a supplier may be able to document one and not the other. A supplier that buys electricity from the grid may have a supplier specific factor or a default factor, depending on the rules and the country.

For a part made from an intermediate product, the emissions of the precursor matter. A machined aluminium housing carries the emissions of the aluminium billet plus the emissions of machining, and the billet may itself carry the emissions of alumina and of the primary metal.

That chain is why a single number from a sustainability brochure is not enough. The declarant needs a figure that can be traced back to the installation and the production route.

The data a supplier has to produce

The request to a supplier should be specific. Ask for the production route, the installation identifier, the reporting period, the direct emissions, the indirect emissions and the precursor quantities and sources.

Ask for the calculation method as well as the result. A number without a method cannot be checked, and a verification body will ask how it was produced. The method should show the activity data, the emission factors and the allocation rules used where a site makes more than one product.

Ask who verified the data and to what standard. If the supplier has no verification yet, ask what they have and when verification is planned. An unverified figure can still be used in some circumstances, but the declarant needs to know which basis applies.

Actual data or default values

Where actual data is not available, default values can be used, but they are usually conservative. A default value is a planning tool and a fallback, not a substitute for supplier data in a competitive programme.

The commercial effect is straightforward. If two suppliers make a similar part and one can document lower emissions, the documented one may carry a lower carbon cost. That difference can be large enough to change a sourcing decision, especially for energy intensive inputs.

Start with the suppliers that represent the most volume or the highest carbon intensity. For the rest, use a default for the first model and set a deadline for actual data. That sequence keeps the programme moving without pretending the data is better than it is.

Verification and the declarant

Verification is an independent check of the emissions data and the method. It is not the same as a supplier's ISO 14001 certificate, which says something about the management system rather than the number.

The declarant is responsible for the declaration, even when the data comes from a supplier. That means the importer needs a file that connects the imported good to the installation, the reporting period, the emissions figure and the verification. If the supplier changes a number after the entry, the declarant needs to know.

Build the file at the purchase order stage, not at the annual declaration. Ask for the data with the order, check it against the previous period and flag a change before it becomes a correction.

Supplier readiness: a realistic timeline

A supplier that has never measured its emissions needs time. Metering, activity data, emission factors and an allocation method can take a season to put in place, and verification adds more.

Ask early and ask in writing. A questionnaire sent a month before the first shipment will produce estimates. A questionnaire sent at the qualification stage will produce a plan, and the plan can be built into the supplier scorecard.

For an Indian supplier, the practical questions are about electricity supply, fuel use, the share of secondary metal and the traceability of billet or ingot. Those four answers usually show whether the data will be usable.

If a supplier cannot meet the requirement, that is a sourcing fact. It belongs in the same review as quality, capacity and cost, not in a separate environmental folder.

Where it lands in the landed cost

Add a carbon cost line to the landed cost model, with the assumed price of carbon, the emissions per part and the share of emissions that carries a cost. Mark the price and the share as assumptions with a date.

Then run a sensitivity. If the carbon cost doubles, does the supplier still win? If the answer changes, the programme has a carbon exposure that should be discussed before the contract, not after the first declaration.

The line does not have to be precise to be useful. It has to be visible, sourced and reviewed. A buyer who can show the carbon line and its assumptions is in a much better position than one who discovers it in the annual declaration.
