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.

Everything is dated and verified against primary sources (Finance Act 2026 + HMRC's draft regulations) and re-versioned as the rules finalise through 2026 — that tracking is our full-time job, not yours.

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 plus a multi-client dashboard: every client's threshold position, data-collection status and liability in one view.

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.
