The seller, exporter, producer and installation operator may all be different entities. Weetra checks whether the file keeps those roles connected instead of treating them as interchangeable.

A commercial document can establish a sale without establishing the production installation. The review can examine seller versus producer, exporter versus installation operator, goods attribution, batch or product relationships, the source of emissions data, supplier declarations, upstream evidence, period consistency and installation relationships.
The invoice identifies the seller. The emissions workbook identifies a plant. The file does not contain sufficient evidence connecting the goods on the invoice to that plant.
Seller, exporter, producer and installation operator are recorded as distinct roles where the evidence shows they are distinct.
Product, lot, batch and commercial references are examined for continuity with production and emissions records.
Supplier declarations are checked against the upstream records available; they are not treated as proof on their own.

Request an Evidence CheckWhen a deeper review is commissioned, Weetra records what was received, what was relied on, what conflicted, what was corrected, what changed and why the final conclusion was reached. That history makes the file easier for an adviser, verifier or authority to understand later.
An invoice can prove a sale without proving where the goods were manufactured. The seller may not be the producer, different documents may name different legal entities, and emissions data can lose its connection to the actual shipment as goods move through intermediaries.
Seller ≠ manufacturer; manufacturer ≠ installation operator; product descriptions differ; quantities or batches do not match; the installation reference disappears; the emissions file cannot be tied to the shipment; precursor information comes from another upstream source; or updated evidence does not reach every downstream party.
The €490 excl. VAT Evidence Check reviews the documents already in the commercial chain and focuses on whether seller, producer, installation, goods, quantities, periods and emissions evidence remain connected.
A deeper review is particularly useful when several intermediaries, producers or installations are involved, when upstream evidence arrives in different versions, or when a downstream party needs a clearer record of which source was ultimately relied on.
The reviewed record can preserve who supplied what, which producer and installation were ultimately relied on, which versions changed, what was corrected and what remained limited. That history can be valuable when the file later moves downstream.
Each finding identifies the documents concerned, what appears to be missing or inconsistent, why it matters, the corrective action to consider and the next step.
Start with the evidence already available. Receive findings, correct or obtain evidence, stop if no deeper work is needed, or move to a deeper review only where the file justifies it. If no deeper review is required, no further engagement is recommended.
A deeper Weetra review can record what was received, what conflicted, what changed, what was corrected, what was ultimately relied on and why the conclusion was reached. That history can later support internal review, professional advice, accredited verification or authority scrutiny.
The commercial supplier remains known, but the producing installation behind the emissions information is no longer evidenced.
The emissions file and commercial shipment refer to different or unclear reporting periods without a documented bridge.
Batch, shipment or invoice quantities cannot be reconciled to the production population used by the upstream emissions calculation.
Manufacturing installation → producer → trader / exporter → EU importer → CBAM declaration. At each handoff, the identifiers and documents needed to understand the reported information should remain intact.
