Data and reporting

    Tonnage reporting

    The annual declaration of packaging weight by material category placed on a market, and the basis for nearly every EPR invoice.

    Tonnage reporting converts sales volume into packaging weight by material and jurisdiction. The calculation is simple; the data lineage is not. It requires units sold resolved to the market of first placement, multiplied by verified component weights, classified into the scheme's material categories.

    Common errors are systematic rather than random: using shipped rather than sold units, missing intercompany transfers, ignoring promotional packaging, and applying a global bill of materials to a regionally different pack.

    Because schemes audit retrospectively, the reporting method should be documented and reproducible. An auditable trail from ERP extract to submitted figure is worth more than a precise number no one can reconstruct.
