CBAM (Carbon Border Adjustment Mechanism) is an EU mechanism for imported high-carbon products:first declare the embedded carbon emissions of the product, then pay the corresponding fee on the difference. Steel (including stainless steel) is within scope.
One-sentence assessment
The single most important thing to do now is turn 'carbon emission data per shipment' into a routine ledger— electricity consumption, fuel consumption, ratio of raw materials to scrap steel, net product weight and the corresponding customs code. Rule details will be adjusted, but this dataset is the foundation of all calculations; accumulating it first will not be wasted effort.
What the mechanism regulates
- Declaration object: specific goods imported into the EU (steel, aluminium, cement, fertilisers, electricity, hydrogen, etc.), with scope determined bygoods code;
- Declaration content: the product'sembedded emissions(direct emissions from the production process + relevant indirect emissions, such as purchased electricity), and quantity;
- Transitional period vs formal period: during the transitional period, declaration is the main requirement (no payment); from the formal period onward, importers must bear the corresponding cost on the difference between embedded emissions and EU free allowances;
- Data source:actual data from the production facilityis preferred; default values are used only when actual data is unavailable, and default values are usually higher than actual values, meaning higher costs.
The specific scope, calculation methods and timetable are subject to thelatest official EU texts— this must be stated clearly, because implementing rules have been adjusted continuously in recent years, and any second-hand account may be outdated.
Checklist of what exporters actually need to prepare
- Customs code alignment: the same batch of 'stainless steel sheet' with different thickness or processing method has different codes, and whether it is in scope may also differ. First clarify the codes for the categories you export;
- Production facility boundary: which production line, which furnace, which processes are counted in this batch of goods;
- Energy consumption data: electricity consumption per tonne of steel, fuel consumption (natural gas/coal/coke), emission factor of purchased electricity;
- Raw material data: ratio of scrap steel to hot metal/alloy materials (the scrap ratio directly affects emission intensity);
- Output basis: must reconcile with customs declaration quantity, net weight and yield, otherwise allocation cannot be calculated;
- Traceability: heat number — batch — order — customs declaration form must be linkable, so customers or verifiers can spot-check.
Why 'using default values' is usually a bigger loss
Default values are set at a relatively conservative industry level. If your actual emissions are lower than the default values (for example, electric furnace short-process, high scrap ratio), using default values is equivalent topaying for a higher amount of carbon. Conversely, only when actual data can be calculated clearly can optimisation and negotiation be discussed.
Common pitfalls
- Assuming 'stainless steel is a high-end material, so it is not covered' — coverage is determined by goods code, not by whether it is 'high-end';
- Waiting until customers ask for data before starting to accumulate it, resulting in being able to report only default values;
- Electricity consumption data covers only melting, omitting major energy-consuming processes such as rolling, annealing and pickling;
- Emission factors are directly taken from the national average, which does not match the facility's actual power supply structure;
- Data lacks documented basis, so when someone else takes over, it cannot be explained clearly.
What we can do: in the delivery process, cooperate in providingtraceability data on batch and weight basis(heat number, batch, net weight, material certificate accompanying the batch), to facilitate your connection with energy consumption data on the production side. As for the specific declaration basis and calculation methods, please refer to the latest official EU rules and the opinions of your customs declaration/compliance advisers.
