Oportax

Product

What Oportax does,
in detail.

Four jobs to do: track your imports, get verified emissions data from your suppliers, see your liability in real time, file with HMRC. Here's how each one works.

1

Import tracking

Drop in your customs broker export, ERP feed, or CSV. Oportax parses, deduplicates, and maps each line to a CBAM commodity code. In-scope and out-of-scope are separated automatically. Edits and corrections leave an audit trail.

In the product

  • Broker, ERP and CSV imports, with column names matched for you
  • Automatic in-scope flagging by commodity code
  • Line-level liability calculation as data is added
  • Period-aware (annual to 2028, quarterly thereafter)
2

Supplier engagement

Every supplier of in-scope goods needs to provide embedded emissions data. Oportax handles outreach for you — multilingual, with automatic chasing, sent on your behalf with your name in the sender line and your own contact copied in. You can send the first one from your own mailbox instead, or authenticate your domain if you have IT support.

In the product

  • Multilingual templates auto-translated and reviewed before sending
  • Three send strategies per supplier: Oportax sends, you send, or copy-paste link
  • Domain authentication so replies come back to you
  • Day 7, 14, 21 automated reminders
  • Mark offline responses (phone, WhatsApp) into the same workflow

Reporting and insight

Liability updates live as supplier data comes in. Sector breakdowns, supplier exposure, year-on-year trend. Decarbonisation modelling lets you see what switching suppliers would do to your bill.

In the product

  • Quarterly liability dashboard
  • Supplier comparison ranked by emission intensity
  • Decarbonisation modelling: "if I replaced X with Y..."
  • Period-over-period trend
4

HMRC filing

When the period closes, Oportax generates the return — PDF for review, CSV for HMRC's process, plus the full audit trail behind every figure.

In the product

  • Return document with full audit trail
  • Board sign-off checklist
  • Full revision history for every imported line
  • Direct HMRC API submission (when their API is live)
