What it captures
Packaging by material and the weight placed on the market, split by the relevant categories — the basis Defra uses to assess obligation and fees.

The Defra RPD submission, explained.
Under UK packaging Extended Producer Responsibility, producers report the packaging they place on the market to Defra. Here is what the Report Packaging Data (RPD) submission asks for in plain terms — and why a submission has to reconcile to the kilogram rather than round a gap away.
Why tonnage must reconcile
The reported tonnage drives a modulated fee. If the figure can’t be tied back to the underlying placements, the number — and the bill — can’t be defended.
Flag, never invent
Where a required field can’t be resolved, a sound submission records the gap rather than filling it with a guess — an invented value is worse than a flagged one.
How Terrametri handles it
A submission that ties to the kilogram or writes no file.
Terrametri derives tonnage from your product and placement data, catches duplicate placements before they count, and produces a Defra RPD export that reconciles or refuses — see UK packaging EPR. This guide is general information, not legal advice; confirm your obligations against the current Defra guidance.
