CBAMReturn

For customs brokers & freight forwarders

From January 2027, every affected client will ask you about CBAM.

You file their customs entries, so their carbon border tax questions will land on your desk — data collection from overseas suppliers, threshold tracking, a new HMRC return cycle. You don't want to build software, and your clients can't afford enterprise carbon platforms. That's the gap CBAMReturn fills: your client relationships, our compliance engine.

The deadline structure your clients face

1 Jan 2027UK CBAM starts — liability accrues on covered imports from day one
£50,000Registration threshold: rolling 12-month customs value, tested monthly, plus a 30-day forward test
31 Jan 2028Registration deadline for every client who crosses during 2027
31 May 2028First return and payment, covering the whole of 2027
From 2028Quarterly returns — a standing compliance cycle, forever

The trap: the May 2028 return is built from data collected during 2027 — and a return filed on default values can never be amended to real supplier data afterwards. Clients who start collecting late pay for it, permanently.

What CBAMReturn does

Scope & threshold

Import ledger in, CBAM lines flagged by commodity code, rolling £50k position tracked monthly — built on the statutory Schedule 16 goods list.

Supplier data

A portal and plain-English template that accept the files overseas mills actually send, with verification requirements built in.

Liability & return

Default versus actual side by side, per-line provenance, building into an HMRC-ready return well before each deadline.

Client workspaces

One organisation per client, roles for your staff and theirs, a checksummed records vault and an audit trail per client, a portfolio view across all of them, exportable as one zip when the engagement ends.

Supplier portal

Send each overseas supplier a private upload link; their file is checked on the spot and, if usable, lands in the client's vault and moves the chase status without anyone re-keying anything.

Security

Two-step verification for every login, a signed-in device list, sign-out-everywhere, and a session model that revokes for real.

Operations

Automated test gate on every change, nightly backups with a rehearsed restore, five-minute uptime checks, and a rules watch on eight primary sources.

Your systems

A read-only API (position per client, portfolio across clients) with per-organisation keys, bulk client import from a CSV, and an engagement record of who is the liable person and who files.

Everything is dated and verified against primary sources (Finance Act 2026 + the regulations made in July 2026) and re-versioned as the rules finalise through 2026 — that tracking is our full-time job, not yours. See it working: the worked example runs a fictional importer's ledger and two supplier files — one tidy, one a mess — through the engine, line by line.

Three ways to partner

Referral

You introduce affected clients; we handle everything; you take a share of first-year revenue. Zero operational lift.

White-label

Your brand on the portal, our engine underneath. Your clients never leave your ecosystem; CBAM becomes a service you offer rather than a question you dodge.

Wholesale seats

Volume pricing on client accounts. Client workspaces are live today: each client is its own organisation with its own ledgers, records vault and audit trail, and the portfolio view shows every client's threshold position, liability and supplier-data coverage in one table.

Early partners shape the product and the commercials before terms are set for the wider market — we're speaking to a small number of brokers and forwarders ahead of the 2027 start.
