What to gather first
Everything in a submission derives from one thing: a complete list of packaging components, each with a material, a weight, and the volume of units that went out in the period. If any of those three is missing for a component, that component cannot be reported correctly, and estimating it is how producers end up with tonnage they cannot defend.
For every packaging component:
- Material, at the granularity the RPD material categories require
- Component weight, per unit, in grams
- Packaging level: primary, secondary or transit
- Intended use: household or commercial
- The activity that brought it into scope
- Units supplied in the reporting period, so weight becomes tonnage
- Recyclability rating from your RAM assessment, for household packaging
- Recycled content, where the component is plastic and Plastic Packaging Tax also applies
The component weights are the item most producers do not have. They live with suppliers, they are rarely on a specification sheet in a usable form, and collecting them by email across a few hundred SKUs is a multi-month exercise the first time it is done.
The submission, step by step
- Confirm your classification. Turnover and tonnage decide whether you are a small or large producer, and that decides what the submission has to contain.
- Register on the Report Packaging Data service, using the Government Gateway account for the organisation that holds the obligation.
- Establish the reporting period. Large producers report January to June and July to December separately. Small producers report the full calendar year.
- Assemble component data for the period: material, weight, level, use, activity and units supplied.
- Split household from commercial. Only household packaging attracts disposal fees, and the split cannot be inferred from a product list where a SKU sells through more than one channel.
- Attach RAM ratings to household components, recorded against the methodology version that applies to the supply year.
- Aggregate to tonnage per material, per level, per use, per activity - the shape the upload expects.
- Validate before you upload: totals that reconcile to your volumes, no blank required fields, materials mapped to the service categories rather than to your own names.
- Upload the file and work through any validation errors the service returns.
- Keep the working. The file you submitted, the data behind it and the assessments that produced the ratings are your evidence if the submission is queried.
Deadlines
| Producer | Deadline | Period covered |
|---|---|---|
| Large | 1 April | July to December of the previous year |
| Large | 1 October | January to June of the current year |
| Small | 1 April | The whole of the previous calendar year |
Registration deadlines sit alongside these. A producer newly crossing a threshold has to register as well as report.
Why submissions get sent back
- Materials mapped to internal names rather than the service's categories, so a whole category reads as zero and another is overstated
- Blank fields in columns that are required for the activity type on that line
- Tonnage that does not reconcile to the volumes on the same line, usually because a component weight was entered per pack rather than per unit
- Household packaging submitted with no recyclability rating attached
- Transit packaging omitted entirely, which shows up as a total that looks implausible against turnover
- The same component reported twice under two activities, double-counting the tonnage
Almost every item on that list is a data-shape problem rather than a filing mistake. A submission built from a component-level record that already holds the material mapping, the household split and the rating does not produce them, because there is nothing left to reconstruct at submission time.
