Supplier emissions data collection
Replace email chaos with secure supplier intake and Magic Links. Keep an audit trail for compliance and procurement.
Supplier portal, progress tracking, audit events
UK CBAM readiness
Check your UK imports before 1 January 2027.
Check commodity-code scope, assess the two £50,000 registration tests, upload actual and expected import records, and download a readiness report with supplier evidence gaps.
Start the self-service check without a card. An optional £299 reviewed pilot includes a corrected report and a short results call, arranged and paid manually. The UK check does not submit an HMRC return or start a subscription.

Built for operations
Quarterly workflows for supplier intake, audit trail, and export-ready submission packs.
Make CBAM reporting repeatable.
CBAM execution depends on supplier cooperation, consistent calculations, and correct submission files. GrandScope is built for that reality.
Calculation
Embedded emissions calculation
Compute report values consistently and apply controlled default values when suppliers do not reply.
Repeatable methodology, fewer spreadsheet errors
Submission
Annex 5.1 XML ZIP export
Generate a portal-ready XML plus attachments packaged as a ZIP and validate structure before submission.
Annex 5.1 structure alignment, reduced rejection risk
How EU CBAM reporting works in GrandScope
A 3 step pipeline from shipment data to a submission-ready export.
01
Import shipments and CN codes
Enter CN codes or upload a CSV from your freight system. Group shipments by supplier and reporting period.
02
Collect supplier inputs
Send suppliers a secure link to provide emissions and activity data. Track completion and follow up only when needed.
03
Export, validate, and file
Generate an Annex 5.1 XML ZIP export and validate structure before submission to reduce last-minute rework.
Start with one report, scale to your full import book.
Use a free report to test the workflow, then expand to multi-entity operations.
Who GrandScope is for
Designed for EU import operations: importers, freight forwarders, and indirect representatives across the EU.
For importers
Run quarterly reporting without chasing dozens of suppliers. Keep documentation aligned with what procurement and auditors demand.
- Quarterly workflow by shipment and supplier
- Attachment management and audit trail
- Consistent data quality controls
For freight forwarders
Standardize CBAM across clients with repeatable intake and reporting. Reduce client escalation and operational drag.
- Multi-client workflow
- Supplier follow-up automation
- Export packs built for portal upload
CBAM covered goods and scope
CBAM initially applies to cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen. Importers must report embedded emissions during the transitional phase.

Common blocker: supplier silence
Waiting for suppliers to learn Annex 5.1 kills reporting timelines. Use structured intake and controlled default values to keep filings on schedule.

FAQ: EU CBAM reporting and Annex 5.1
Direct answers for operations, compliance, and procurement teams.
What is EU CBAM and who needs to report?
The Carbon Border Adjustment Mechanism is the EU policy tool that puts a fair price on carbon embedded in certain imported goods. During the transitional phase, importers report embedded emissions for covered goods.
How do I submit a CBAM report?
Reporting declarants can create reports in the portal or upload an XML file with attachments packaged in a ZIP. The XML is structured according to the Annex 5.1 XSD.
What penalties apply if reports are missing or incorrect?
Penalties can be between EUR 10 and EUR 50 per tonne of unreported embedded emissions, depending on the competent authority assessment and the case.
Can I use default values if a supplier does not reply?
GrandScope supports controlled fallback to default values so you can file on time, then replace with supplier specific values as data becomes available.
What information do I need from suppliers for CBAM reporting?
You typically need supplier activity data and embedded emissions inputs for covered goods, plus supporting documentation where available. When suppliers do not respond in time, controlled default values can keep submissions on schedule.
What is Annex 5.1 and why does XML validation matter?
Annex 5.1 defines the reporting structure used for portal uploads. If the XML structure does not match the Annex 5.1 XSD, uploads can fail and create last-minute rework. Validation helps catch structural issues before submission.
How do CN codes affect CBAM scope and reporting?
CN codes determine whether a shipment line is in scope and how it should be categorized for reporting. Incorrect CN mapping can lead to missed covered goods, inconsistent data, and preventable portal errors.
What documentation should I keep for CBAM audit readiness?
Keep supplier submissions, calculation inputs, default value rationale where used, and any supporting documents associated with your reporting period. A clean audit trail reduces time spent answering internal reviews and competent authority questions.
What changes when the definitive regime starts on 1 January 2026?
The transitional phase focuses on reporting. From 1 January 2026, requirements expand toward certificate management and financial settlement linked to embedded emissions. Being operationally ready means having repeatable data collection and calculation workflows.
Can freight forwarders or indirect representatives report on behalf of clients?
Many forwarders and indirect representatives support clients with shipment data, supplier follow-up, and preparation of submission packs. The reporting declarant remains responsible for correctness, so standardized intake and validation are key.
Make CBAM boring.
Predictable reporting beats heroic last-minute compliance every quarter.
