Regulatory data must be traceable, reviewable and supported by evidence.
Weetra checks whether regulatory figures and statements are supported by the documents behind them. CBAM is the main service in operation today. EUDR and the Digital Product Passport are developing areas with different legal requirements. For CBAM, you can start with the documents you already have through the €490 excl. VAT Evidence Check.
€490 excl. VAT per dossier
The €490 Evidence Check fee may be credited against a subsequent eligible Weetra review under the applicable commercial terms.
Start with a CBAM Evidence Check.
€490 excl. VAT per dossier
A rapid first review of visible evidence weaknesses. The client can correct the issues itself, stop if no deeper work is needed, or move directly to the review level the file justifies.
Evidence Check
Initial review. No Determination.
Documentary Review
What the current documentary record actually supports.
Detailed Documentary Review
A deeper comparison of documents, figures and calculations, with follow-up on inconsistencies where included.
Detailed Review
A detailed review of complex or high-risk files, tracing important figures back to their source documents and testing unresolved points.
This is not a mandatory linear journey. A file can stop after the Check or move directly to the Level the findings justify.
If no deeper review is required, no further engagement is recommended.
Three regulatory evidence domains
Weetra is an independent regulatory documentary review organisation. Its main operational focus today is CBAM. EUDR and DPP are developing areas with different legal requirements.
CBAM
Goods → producer → installation → emissions → supporting documents. CBAM is Weetra’s main operational focus today. EUDR and Digital Product Passport work are still developing; the site explains their documentary requirements without presenting them as equivalent commercial services.
EUDR
EUDR requires a clear trail from the product and commodity back to its production source, geolocation, legality records, deforestation-free status, risk assessment and due-diligence records.
Digital Product Passport
Digital accessibility does not make the underlying information reliable by itself. DPP data still needs reliable identifiers, clear sources, version history and durable access.
Why documentary evidence matters
CBAM rules require records detailed enough to support verification where applicable and later review. Weetra reviews the documentary record against that reality.
Regulatory references provide the legal context. Weetra does not provide legal advice or accredited verification.
Where do you sit in the documentary chain?
The same CBAM file should not be read the same way for an importer, a non-EU producer, a trader or an adviser acting for the client.
Check the evidence supporting your imported goods.
Goods, quantities, supplier, producer, installation, emissions and supporting records.
See the pathway →Non-EU producerCheck the evidence package supplied to EU customers.
Installation, production, monitoring, calculations, precursors and source records.
See the pathway →Trader / exporter / supplierCheck continuity between seller, producer and installation.
A commercial sale does not automatically prove where goods were produced.
See the pathway →Adviser / customs professionalCheck a client file before choosing review depth.
A focused first check can remain inside the adviser-led mandate.
See the pathway →What can Weetra find?
The first question is simple: which parts of the file can be confirmed from the documents, and which cannot?
Missing supplier evidence
Wrong installation attribution
Period mismatch
Quantity discrepancy
Outdated monitoring plan
Different documentary versions
Unsupported precursor information
A calculation that cannot be reproduced from the supplied records
What happens when deeper review is required
Scope and the set of documents are agreed
The mandate identifies the goods, suppliers, installations, periods, questions and documents in scope under review. Anything outside that boundary remains outside the conclusion.Relevant documents and reported figures are identified
Weetra identifies the records relied on for the positions in the file and the regulatory questions those records are expected to support. The objective is to understand what the file is actually asserting before testing whether the documentary basis holds together.Data are compared across sources
Quantities, installation identities, periods, supplier information, emissions data and supporting calculations are compared across the available records. Calculations are reproduced where the mandate, governing rule and necessary inputs allow it.Missing documents, inconsistencies and points that cannot be confirmed are documented
A missing document is not treated as the same thing as conflicting information, and a point that cannot be fully confirmed is not presented as a factual error. Each issue is described for what the documents actually show.Questions and corrections are handled when included
Where follow-up is included, Weetra identifies what needs clarification or correction. The client, supplier, adviser or relevant operational team provides the new material. Weetra then examines the updated file.Weetra issues its Determination and preserves the reviewed basis
The Determination records what the reviewed file supports at the agreed cut-off, including any limitations or conditions affecting finalisation. Where the engagement provides for it, supporting review records preserve the documentary basis needed to understand that conclusion later.The Levels describe review depth, not file quality.
CBAM Evidence Check
Focused first check for visible documentary weaknesses. No Weetra Determination.
CBAM Documentary Review
Reviews what the existing CBAM documentary record currently supports.
CBAM Detailed Documentary Review
Compares documents, figures and calculations across the file, with follow-up on inconsistencies when included.
CBAM Detailed Review
A detailed review of complex or high-risk CBAM files, tracing important figures back to source documents and testing unresolved points more closely.
A Level III file is not “better” than a Level I file. Depth changes what is examined, not what the evidence will reveal.
A deeper review leaves a file another professional can understand later.
The report records the Determination. The supporting review record preserves the basis that led to it.
When a Determination Package is included, another professional can see which documents were examined, what did not match, what was corrected, what remains unresolved and why Weetra reached its conclusion. Accredited verifiers and other professionals remain responsible for their own work and conclusions.
CBAM documentary evidence review
CBAM is Weetra’s current operational focus. Weetra examines whether the documents connect goods, installations, embedded emissions and the calculations relied on.
CBAM is operational. EUDR and DPP are developing evidence domains.

Latest regulatory developments
CBAM 50-tonne threshold: Commission publishes first assessment
The Commission assessed the CBAM 50-tonne single mass-based threshold using data for 1 April 2025 to 31 March 2026. It found that the threshold would exempt 0.87% of embedded emissions, below the 1% limit. The assessment does not itself change the current 50-tonne threshold.
Information System rules simplified ahead of application
Commission Implementing Regulation (EU) 2026/1565 amended the EUDR Information System rules, including due-diligence statement submission and simplified statements for certain micro or small primary operators. Documentary implication: reference numbers, corrections and supply-chain handoffs need disciplined record keeping.
Digital Product Passport Registry launched
The Commission launched the DPP Registry and testing environment following Implementing Regulation (EU) 2026/1778. Harmonised DPP standards were published through Implementing Decision (EU) 2026/1736. Documentary implication: unique identifiers, source history, versioning, storage and persistence become practical implementation questions.

2026Read overview →From the file you have to a reviewed record another professional can understand.
The starting point is simple. Review depth changes only when the evidence problem justifies it.
The evidence already available
Commercial, customs, supplier, installation, monitoring, calculation, precursor and verification-related records, according to the file.
How the documents connect
Identity, quantities, periods, installation attribution, how the calculation was built, which document versions were used, what conflicts and what could not be confirmed.
Findings at the commissioned depth
The Evidence Check returns focused findings. Deeper reviews can result in a Determination under professional responsibility and, when included, a Determination Package.
Correct, stop, or move to a deeper review
If the file can be corrected internally, no further engagement is required. A deeper review is recommended only when the evidence justifies it.
A conclusion is only useful if another professional can see how it was reached.
Weetra does not sell a favourable result. The scope, documents reviewed, inconsistencies, corrections, unresolved points and final conclusion remain clearly recorded within the engagement.
Defined mandate
The goods, entities, installations, period, document set and review depth are defined so the conclusion cannot go beyond the evidence examined.
Human accountability
Tools may assist with consistency checks. A named reviewer remains responsible for any Weetra Determination.
Visible limitations
Missing documents, inconsistencies and unresolved points remain visible rather than being reduced to a cosmetic score.
Independent regulatory evidence review, built for files that may be questioned later.
Weetra is a Paris-based regulatory documentary review organisation focused on whether regulatory information can be traced to the documents that support it. CBAM is its main operational focus today.
