The first Extended Producer Responsibility (EPR) report is the one that intimidates teams the most. Once you understand the sequence, confirm obligation, gather packaging data, classify materials, calculate quantities, and submit through the right channel, the process becomes repeatable. This walkthrough breaks down a first packaging EPR report into manageable stages so the second cycle is a refinement, not a rebuild.

Before You Start: Confirm You Have an Obligation

Before any data work begins, confirm that your company is actually a "covered producer" in the jurisdiction where you plan to report. Every EPR statute defines the obligated party slightly differently, and the definition typically combines three tests: a producer definition (brand owner, importer, first domestic seller, or marketplace), a set of covered materials (often packaging by format and material type), and a de minimis threshold based on revenue, tonnage, or both.

Run those three tests for each jurisdiction. If your company sits below the de minimis threshold or sells only out-of-scope materials, you may have no reporting obligation at all for that period, though some jurisdictions still require a registration or exemption filing. For a primer on the foundational concepts, see our overview of what is EPR. For the threshold question specifically, our guide to small producer thresholds and de minimis rules across the UK, EU, and US walks through how the cutoffs differ by jurisdiction.

Documenting the obligation analysis in writing matters. If your company is later audited or asked to explain why it did not register in a given jurisdiction, the obligation memo is your defense.

Step 1, Register as a Producer

Registration almost always comes before the first report. Most jurisdictions require producers to register either directly with the regulator or through a designated Producer Responsibility Organization (PRO). Registration typically captures the legal entity name, tax or company identifier, contact details, the jurisdictions in which the producer operates, the product categories placed on the market, and in some cases a high-level estimate of tonnages.

Registration deadlines run on their own clock and usually precede the first reporting deadline by several months. Missing the registration window can lock a producer out of the reporting portal entirely or trigger late fees that compound before any tonnage is even reported. Plan registration as a distinct project with its own internal owner, and confirm what proof or documentation the PRO requires, such as an entity registration certificate, VAT number, or signed authorization for a representative.

Step 2, Build Your Packaging Inventory

The packaging inventory is the foundation of every EPR report. The objective is a complete list of every packaging component placed on the market during the reporting period, organized by SKU. Completeness matters more than precision at this stage: missing components are the single most common first-report error and the one most often surfaced in audits.

A useful inventory captures all three layers of packaging. Primary packaging is what directly contains the product, such as a bottle, pouch, or tube. Secondary packaging is the unit that groups primary packs for retail display, such as a multipack carton. Tertiary packaging is the transport and grouping packaging, including pallets, stretch wrap, corrugated shippers, and dunnage. Many first reports underreport tertiary packaging because the data sits with logistics teams rather than packaging engineers, but it is fully in scope under most EPR programs.

Build the inventory at the component level rather than the SKU level. A single SKU can include a bottle, a closure, a label, a shrink sleeve, and a corrugated shipper, each made of a different material with a different weight and recyclability profile. Treating each as its own row makes downstream calculations and material classification far easier.

Step 3, Capture Material and Weight Data

Most EPR fees are weight and material based, so each component needs a recorded material type and an empty weight. Source this data from packaging specifications, supplier data sheets, or direct measurement. When specifications conflict with reality, measurement wins, but specs are usually the right starting point.

Three rules make this step easier in every subsequent cycle. First, use consistent units across the inventory, typically grams per component. Second, treat each material layer separately, including caps, labels, liners, and laminate layers, since a multi-material component is rarely a single fee category. Third, record the source of each weight value so you can defend it later. Our guide to the packaging data model fields you actually need at SKU and component level details the data structure that supports reporting across multiple jurisdictions without rebuilding the spreadsheet every quarter.

Step 4, Classify Materials Correctly

Each component must be mapped to the jurisdiction's official material categories and recyclability classifications. Misclassification is one of the most direct ways to overpay or underpay fees, because base fee rates and any eco-modulation adjustments are tied to the material category. A bottle classified as PET versus a bottle classified as "other rigid plastic" can carry meaningfully different per-tonne fees.

Eco-modulation, where the fee per tonne is adjusted up or down based on recyclability, recycled content, or design choices, depends entirely on getting the classification right. For a deeper look at how design choices translate into fee differences, see our analysis of eco-modulation across jurisdictions. The same physical component can carry different classifications in different jurisdictions, which is why the data model should keep the underlying material attributes separate from the jurisdiction-specific classification mapping.

Step 5, Calculate Quantities Placed on the Market

With per-component weights and classifications in place, the calculation is straightforward in principle: multiply the per-unit packaging weight of each component by the number of units sold in the jurisdiction during the reporting period, then aggregate to the jurisdictional totals required by the regulator or PRO.

In practice, the difficulty sits in the attribution. Units sold need to be allocated to the correct country, the correct channel (own retail, wholesale, ecommerce, marketplace), and the correct legal entity. A unit shipped from a central warehouse can end up in three different jurisdictions, each with its own report. Our deep dive on channel and country attribution as a data engineering problem explains the patterns that hold up under audit. For the first report, even a simple, documented attribution rule is better than no rule at all.

Step 6, Submit Through the Correct Channel

Each jurisdiction designates a submission channel, typically the PRO portal, a regulator-operated portal, or in a few cases a direct file upload to an environmental agency. The format is usually a structured CSV or web form with strict validation: missing columns, unexpected material codes, or rounded weights can all trigger rejection.

Build in a submission rehearsal before the deadline. Export the report, run it against the validation rules, and resolve every error in the staging environment before the live submission. Keep the submission confirmation, including timestamp and reference number, alongside the source data. Most jurisdictions require the producer, not the PRO, to retain ultimate responsibility for the accuracy of the filing.

Step 7, Keep Evidence and Prepare for Audit

A submitted report is not a closed report. Regulators and PROs can request supporting evidence months or years after submission. Retain the source packaging specifications, the calculation workbook or system export, the material classification mapping, and the submission confirmation as a single, retrievable evidence package per reporting period.

The standard most teams should aim for is being able to reconstruct any submitted number in 24 hours or less. For a practical framework, see our walkthrough of getting EPR and PPWR audit ready in 24 hours.

Common First-Report Mistakes to Avoid

Most first-report problems cluster into a small set of patterns. The most common are an incomplete packaging inventory (usually missing tertiary or secondary packaging), inconsistent units across components, misclassified materials that distort fees, missing or incorrect channel and country attribution, and late or missed registration ahead of the first reporting cycle. Each one is preventable, and each one is far cheaper to fix in the first cycle than in the third.

A short pre-submission checklist for each cycle:

• Confirm every SKU has every component represented, including transport packaging.
• Verify all weights are in the same unit and tied to a documented source.
• Reconcile the material classification mapping against the current jurisdictional taxonomy.
• Validate channel and country attribution against actual sales records.
• Confirm registration is current and the reporting portal credentials work before the deadline week.
