A new Rotterdam aluminium billet benchmark is providing traders with a calculated reference that separates the regional metal premium from assumed customs, logistics and CBAM costs.
Fastmarkets launched its weekly MB-AL-0440 aluminium 6063 extrusion billet premium, CIF Rotterdam, on 31 July. The assessment is derived from an existing delivered North Germany price rather than from a separate survey of Rotterdam transactions.
The methodology starts with the delivered value of the aluminium and deducts assumed duty, transport and carbon costs. It then isolates the underlying exchange price to calculate the premium. The CBAM element incorporates representative assumptions covering origin, emissions and certificate costs.
Benchmark assumptions differ from shipment liabilities
The Rotterdam reference is a market comparison instrument and does not establish the CBAM liability for an individual shipment. Actual costs can differ where the shipment has a different origin, tariff treatment, verified emissions profile or delivery arrangement from those assumed in the methodology.
The distinction is relevant when traders compare imported aluminium offers with European delivered prices. Applying one common reference can show how offers compare, but it does not eliminate differences in the physical or regulatory conditions attached to each transaction.
The calculation also distinguishes between different pricing bases. Buyers can compare a value excluding border and carbon costs with an all-in delivered price, but moving between those bases requires reconciliation of the individual cost components.
Shipment-level costs remain separate
The new reference can provide a common point for commercial negotiations, while the final cost of bringing billet into Europe remains dependent on the characteristics of the shipment.
Differences in origin, emissions, tariffs, transport and CBAM treatment can change the actual landed cost even when two offers are assessed against the same Rotterdam reference.
The benchmark therefore separates assumed carbon and border costs from the aluminium premium without replacing the transaction-level work required to establish the actual cost of imported metal.
