What to check first

• Confirm which aluminium products are in scope: the sector covers unwrought aluminium, powders and flakes, semi-finished forms (bars, wire, plate, foil, tube), and a broad range of finished articles.
• Check each product's full CN code with the goods checker rather than relying on the chapter heading, so downstream articles are not missed.
• Request embedded-emissions data from your aluminium suppliers, including any upstream smelting data behind semi-finished forms.
• Estimate your cumulative annual net mass against the 50-tonne de-minimis threshold before assuming an exemption applies.
• Follow the officially published certificate price when planning cost exposure, and note the key 2026–2027 dates.

Read aluminium scope as a chain of product forms

The current aluminium list spans unwrought metal, powders, semi-finished forms, and selected downstream articles. That range makes commercial labels unreliable shortcuts: ‘extrusion’, ‘sheet’, ‘foil’, ‘container’, or ‘fabricated aluminium part’ still needs the exact customs record. Follow how product form changes through the chain while using the reviewed Annex I goods data for the current covered-goods lookup.

Aluminium procurement often groups products by alloy, temper, finish, or end use. Annex I is organised by customs entries instead. Unwrought metal sits nearer the start of the metal chain; bars, profiles, wire, plate, sheet, strip, foil, tubes, and fittings describe semi-finished or converted forms; structures, containers, stranded products, and other articles reach further downstream. The presence of these different forms is why neither ‘primary aluminium only’ nor ‘every aluminium-containing product’ is a safe description of current scope.

Create one scope record per imported line. Retain the code used in the customs declaration, official description, purchasing description, alloy or grade where relevant to traceability, physical form, dimensions, finish, and lookup source date. Do not infer the code from an alloy certificate, metal content, or the supplier’s use of a broad word such as extrusion. A profile that is cut, drilled, assembled, or supplied as part of a system may have a different customs record from the billet or unworked profile behind it.

Product change control is especially useful for aluminium. A buyer may move from coil to formed panels, from plain foil to backed or printed material, from tube to a fitted assembly, or from standard profiles to prepared structural components. Capture the imported presentation, not only the base metal. If a product is redesigned, bundled with non-aluminium components, or supplied under a new customs description, reopen the lookup rather than copying the status from the previous SKU.

• Separate unwrought, powder, semi-finished, and downstream-article records instead of treating aluminium as one product row.
• Keep exact customs and product descriptions beside alloy, temper, form, dimensions, finish, and commercial SKU.
• Record when cutting, backing, printing, fitting, assembly, or preparation for structural use changes the imported product.
• Use the current derived goods checker for the code lookup; keep proposals clearly labelled and outside adopted results until reviewed after adoption.

Map primary metal, casthouse, and semi-finished production

An aluminium evidence chain usually needs more than the final extruder or rolling mill. Map the smelter or primary-metal source where relevant, the casthouse that produced ingot, billet, or slab, and the rolling, extrusion, drawing, tube, foil, or fabrication sites that made the imported form. Keep each operator and installation separate even when they belong to one corporate group.

A common chain begins with primary metal production, moves through a casthouse, and then reaches a rolling mill or extrusion plant. Other chains may combine primary and recycled inputs, remelt purchased metal, or use intermediate metal bought from several producers. Downstream conversion can include rolling, extrusion, drawing, annealing, slitting, coating, printing, forming, machining, welding, and assembly. The exact route varies by product. The preparation record should preserve the supplier’s description rather than force every order into a single standard diagram.

Start at the imported product and work upstream. Identify the final producing or fabricating site, its input metal form, and the supplier of that input. Continue until the records reach the installation context needed for the emissions data being offered. A direct extruder may provide a product figure that includes upstream billet information, or it may provide only the extrusion stage. Record which is true. A distributor may have traceability to an extrusion batch but no smelter data; keep both the useful link and the missing upstream field visible.

Do not collapse legal entities and installations. A multinational aluminium supplier can operate several smelters, casthouses, rolling mills, and extrusion plants with different energy arrangements and reporting records. A corporate average or brand claim should not be silently attached to every site. Record the operator, installation, process, reporting period, material flow, and source reference that the supplier actually identifies.

• Metal source: primary, remelted, recycled, or mixed description as supplied, without turning the label into an emissions conclusion.
• Casthouse: site, operator, output form, alloy or product family, period, and link to incoming metal sources.
• Conversion: rolling, extrusion, drawing, foil production, tube making, heat treatment, coating, or other operations by site.
• Fabrication: cutting, machining, forming, joining, assembly, finishing, packaging, and the connection to the imported SKU.

Follow evidence through smelter, cast, rolling, and extrusion handoffs

Aluminium data can break at the handoff between primary metal, cast product, and semi-finished production. A durable record identifies the batch or allocation reference available at each stage, the quantity and period covered, the source installation, and whether upstream information is included. It does not assume that a downstream processor’s number contains the smelter history.

At the smelter or primary-metal stage, retain the operator and installation, reporting period, production route description, output covered, data basis, and supporting report reference. At the casthouse, record incoming metal categories as supplied, output form, alloy family where relevant, and the method the supplier used to connect input metal with billet, slab, ingot, or other cast product. At the rolling or extrusion stage, retain the input cast-product source, process site, product family, and allocation or batch explanation.

Commercial traceability will not always follow one physical unit from smelter to finished profile. Metal can be pooled, cast in batches, remelted, or sourced under mass-balance or allocation systems described by the operator. Do not invent a one-to-one heat history when the supplier does not provide one. Preserve the supplier’s allocation explanation, scope, period, and controls as evidence for later review. Use the specialist evidence and verification guidance to assess whether that evidence can support a declared actual-emissions figure; this overview does not make that determination.

When an extruder, roller, or fabricator changes billet, slab, or coil supplier, create a dated chain version. Link affected purchase orders or import lines to that version. If several sources are mixed, keep them separately identified where the data allows and record the supplier’s aggregation basis. The goal is to prevent a well-documented source from masking an unavailable source within the same product family.

Keep electricity context factual and installation-specific

Electricity can be an important part of aluminium production context, particularly at energy-intensive stages, but a country label, power contract, renewable claim, or grid headline does not by itself establish a CBAM emissions result. Record the installation’s electricity information, period, boundary, source, and method description without drawing an unsupported conclusion.

Ask what the supplier’s figure includes. A primary-metal record may identify electricity consumption and an emissions basis for the producing installation. A casthouse, rolling mill, or extrusion site may report its own purchased electricity separately. Some product records may include upstream electricity information; others may stop at the local conversion process. The same word ‘indirect’ can be used loosely in commercial documents, so retain the document’s definitions and refer method questions to the adopted emissions-calculation material.

Keep market instruments and physical supply descriptions as facts supplied by the operator. A power-purchase agreement, certificate, self-generation claim, grid connection, or renewable percentage may be relevant evidence, but do not decide its official treatment from the claim alone. Record the installation, contract or source reference, covered period, claimed quantity, and relationship to the reported production. Do not substitute a national grid story for installation evidence or infer one plant’s data from another plant in the same country.

Changes in power source or production schedule need versioning. If a supplier revises its electricity evidence, reporting boundary, or production allocation, preserve the old and new records and identify affected goods periods. This supports later review without claiming that electricity data is verified, accepted, or sufficient. It also keeps the page clear of unsupported conclusions such as ‘hydro-powered aluminium has no CBAM exposure’ or ‘recycled aluminium is automatically low emission.’

• Identify the installation and production stage to which the electricity information belongs.
• Retain the reporting period, quantity basis, source document, boundary, and supplier’s method description.
• Separate local conversion-site electricity from upstream primary-metal information.
• Record contracts, certificates, self-generation, or grid claims as evidence references, not as automatic official treatment.

Connect semi-finished metal to downstream aluminium articles

Downstream aluminium records should link the imported article to its billet, slab, coil, foil, wire, tube, or profile inputs and to the sites that transformed them. Preserve component and source changes, especially for structures, containers, assemblies, and ‘other articles’, where a broad commercial description can hide multiple production chains.

For a simple profile, the link may run from billet batch to extrusion lot to finishing and shipment. For a façade element, frame, tank, compressed-gas container, cable product, or fabricated bracket, the chain can include several aluminium forms plus purchased components and outsourced operations. Record the bill-of-material or production reference used by the supplier, but do not assume every component follows the same customs entry or emissions basis as the imported article.

Keep transformation records concise and physical: cut, extruded, rolled, drawn, annealed, coated, printed, formed, machined, welded, assembled, or packed. Identify the site and period. If the supplier applies one product footprint to a family of shapes or sizes, record the family definition and allocation explanation. Do not silently apply it to a new alloy, temper, wall thickness, finishing route, or fabricated configuration outside that definition.

Documents can have different jobs. An alloy certificate may establish composition; an extrusion report may show process and batch; an energy invoice may support a site record; a footprint study may describe a broader boundary; and a verifier report has its own status. Link them without treating one as a substitute for all the others. If the chain remains incomplete, the preparation status is ‘upstream source unavailable’ or another factual gap, not zero and not a negative scope verdict.

Organise aluminium supplier follow-up by production stage

Aluminium requests work better when they are directed to the party that owns each stage. The smelter or primary-metal producer, casthouse, rolling mill, extruder, fabricator, trader, and importer may each hold different parts of the record. A stage-based request register makes those ownership gaps visible without duplicating the specialist supplier template.

Ask the direct supplier first for a chain map tied to the ordered goods: final site, input form, upstream producer or source, reporting period, and document references. Then direct follow-up questions to the data owner. The casthouse should not be assumed to own an extruder’s allocation record, and the extruder should not be assumed to own the smelter’s monitoring plan. A trader can coordinate permissions and introductions, while each document retains its original issuer.

Separate product questions from emissions questions. Product identity covers code, description, alloy, temper, form, finish, dimensions, and order references. Chain questions cover operators, installations, input metal, and transformations. Data questions cover period, units, boundary, actual or default basis, electricity context, source documents, revisions, and verification status. This structure helps procurement obtain a usable answer even when the supplier cannot complete every field at once.

End the aluminium review with an actionable queue, not a cost output. Flag missing smelter links, unknown input-metal sources, mixed cast-product sources, corporate averages without installation coverage, electricity claims without period or boundary, reused reports after a source change, and fabricated articles with no component map. Assign each gap to a person and continue to the supplier-request, evidence, calculation, threshold, or verification route when that specialist job begins.
