How to Collect Packaging Data from Your Orders for EPR
Building a per-SKU packaging spec sheet, from the first weighing to the quarterly audit
To collect packaging data for EPR, build a packaging specification sheet for every SKU: weigh each component in grams – primary box, shipping carton, void fill, tape and labels – then multiply by the units sold per country per reporting period. Components under 5 percent of total weight can usually be reported under the dominant material.
Manually weighing every component for every product variation takes hours you do not have, but guessing is not an option: inaccurate reporting exposes you to retroactive fees and marketplace suspensions.
Key takeaways
- You must track the material type and weight in grams for every packaging component, from the primary box to the shipping tape.
- Creating a packaging specification sheet for each stock-keeping unit is the foundation of accurate reporting.
- Composite packaging rules dictate whether you report mixed materials separately or under the dominant material.
What packaging components do I need to track?
According to the United Kingdom extended producer responsibility for packaging guidance, producers must collect data on the packaging activity, the class (primary, secondary, shipment, or tertiary), and the material weight.
This means you cannot just weigh the product box. You must track the primary product packaging, the secondary grouping packaging, the outer shipping cartons, the void fill (like bubble wrap or paper padding), and even the tape and labels.
How do I calculate packaging weight per order?
The most reliable method is to create a packaging specification sheet for each active stock-keeping unit. This involves physically weighing each packaging component in grams using a highly accurate scale, or requesting this exact data directly from your suppliers. You then multiply the weight of each component by the exact number of units sold within a specific reporting period and destination country.
For merchants with hundreds of product variations, the Canadian multi-material stewardship board guidelines recommend an average bill of materials method. With this approach, you calculate the average weights of materials for groups of similar products instead of weighing every single minor variation. By understanding how EPR fees are calculated, you will see that accurate per-gram tracking directly controls your total compliance costs.
How do the 5 percent rules affect composite packaging?
Packaging made of multiple materials requires careful classification. Many Producer Responsibility Organisations apply a component threshold rule for reporting. If an ancillary component, such as a paper label on a plastic bottle, weighs less than 5 percent of the total packaging weight, you may report it under the dominant material category.
If it weighs more than 5 percent and can be separated by the consumer, it must be reported as a distinct material. Furthermore, if you use inseparable composite packaging, such as a paper mailer lined with plastic bubble wrap, authorities often require you to declare the entire package under a composite fraction. This attracts severe penalties, which is why eco-modulation rules heavily favour mono-materials.
Every EPR report is based on correct packaging data, and if an authority audit uncovers a calculation mistake, you are financially responsible for the retroactive costs and penalties.
Stop wrestling with complex spreadsheets and manual weight calculations every quarter. Let Gramta automate your compliance reporting directly from your real order data.
How do I handle Amazon FBA packaging?
If you use Amazon FBA, Amazon adds its own shipping boxes, tape, and void fill to your products. In most European markets, this extra packaging counts towards your obligation because you hired the fulfilment centre to ship the order.
You must ask Seller Central support for an outbound packaging specification to include in your own data logs. Failing to account for this added material is a primary reason sellers face enforcement under strict Amazon Extended Producer Responsibility rules.
How can I avoid data reporting errors?
The most common mistake is failing to update your specification sheets when a supplier changes a box size or switches void fill materials. A quarterly packaging audit is essential. You must check every active stock-keeping unit to verify that the material, weight, and supplier remain identical to your baseline data.
Because many reporting systems, like the German LUCID packaging register declarations, demand strict data consistency, any unrecorded change in your supply chain leads directly to an inaccurate filing.
Do not risk compliance fines because of messy packaging data. Start using Gramta today to automatically track your material weights and generate audit-proof reports for every European market.

Frequently asked questions
- What packaging do I need to weigh for my EPR report?
- You must account for every component used to ship your product, including primary product boxes, secondary grouping materials, shipping cartons, void fill, tape, and labels.
- How do I report packaging made of multiple materials?
- For components weighing less than 5 percent of the total package, you can typically report them under the dominant material. Inseparable composite materials are usually reported under the heaviest material fraction.
- Do I pay for the packaging Amazon FBA adds to my orders?
- Yes, in most European markets, if you hire a fulfilment partner like Amazon FBA to ship your goods, you remain legally responsible for reporting and paying the EPR fees for that added outbound packaging.
