One Recycled Content Evidence Record, Three Jurisdictions: A Cross-Jurisdiction Model
UK PPT, EU PPWR, and US state recycled content mandates each have their own evidence rules. Here is how to build the evidence record once and produce jurisdiction-specific outputs without re-collecting supplier data three times.

The duplication problem
Recycled content claims show up in at least three regulatory regimes producers care about: UK Plastic Packaging Tax (the 30% threshold), EU PPWR (Article-level recycled content mandates for plastic packaging), and US state mandates (California SB 54, Washington's recycled content requirements, New Jersey, and others coming online).
Most producers handle this with three separate evidence collection workflows, each jurisdiction-specific, each starting from scratch with suppliers, each producing its own filing artifact. The result is supplier fatigue, inconsistent claims, and a recycled content number that mysteriously varies depending on which form is being filled out.
A unified evidence model collects the data once at the supplier level, then maps to jurisdiction-specific outputs. The supplier interaction is one workflow. The filings are derived.
What the jurisdictions actually require
Each regime has its own rules, but the underlying data is largely the same. The differences are in thresholds, in evidence formats, and in which inputs count.
UK Plastic Packaging Tax. Per-component, 30% threshold, measured by weight, with HMRC-aligned evidence (supplier declaration, mass balance or segregated, batch-level traceability). Refer to HMRC's current published evidence guidance.
EU PPWR. Article-level mandates for minimum recycled content in certain plastic packaging categories (contact-sensitive vs non-contact-sensitive, with different thresholds). Phased increases through 2030 and 2040. Mass balance methodologies are referenced but rules are still being clarified through implementing acts.
US state mandates.
- California SB 54minimum post-consumer recycled content for plastic packaging, with phased increases. Verification through CalRecycle reporting.
- Washington staterecycled content requirements for specified plastic products and packaging, with annual reporting.
- New Jersey, Connecticut, othersstate-specific PCR thresholds with their own evidence expectations. Refer to each state's current PCR rule for 2026 status.
The common ground:
- Recycled content measured as a percentage of plastic content by weight.
- Distinction between post-consumer and pre-consumer recycled content (most US state mandates count only post-consumer; UK PPT counts both).
- Evidence chain from resin supplier through converter to finished component.
- Mass balance vs segregated methodology distinction.
The unified evidence record
The data captured per component should be sufficient for any of the three jurisdictions:
At the resin level (per supplier, per resin grade):
- Supplier name, site, and contact for compliance correspondence.
- Resin grade identifier.
- Recycled content percentage, broken into post-consumer and pre-consumer.
- Methodology: mass balance vs segregated (with the specific mass balance scheme name, if applicable).
- Independent certification reference (third-party cert ID, scope, validity).
- Supplier declaration document reference, with effective date and renewal date.
- Production-period evidence (batch records, mass balance ledgers) reference.
At the component level (per component, per production run):
- Component identifier and parent SKU.
- Production date or production run identifier.
- Resin grade(s) used and proportions.
- Calculated recycled content percentage at the component level (which may differ from resin-grade level due to additives, coatings, or multi-resin construction).
- Total component weight.
- Plastic-content weight (for "predominantly plastic" determinations).
At the placement level (per filing period, per jurisdiction):
- Volume of components placed on market in that jurisdiction.
- Country/state allocation of that volume.
- Calculated jurisdiction-specific filing inputs (UK PPT taxable tonnage, PPWR per-category recycled content percentage, US state PCR compliance).
How the same record drives different filings
Once the evidence record is in place, each jurisdiction's filing is a derivation:
- UK PPT filing. Filter components above 30% (and meeting evidence quality thresholds), exempt. Sum components below 30%, taxable tonnage times HMRC rate.
- PPWR claim. For each PPWR plastic category, take placed-on-market volume times component-level recycled content percentage, weighted by volume, category recycled content percentage. Compare against PPWR thresholds.
- California SB 54. For each covered category, sum post-consumer recycled content (excluding pre-consumer) times placed-on-market volume, category PCR percentage. Compare against SB 54 schedule.
Same underlying records, three different aggregations. No supplier was emailed three times.
Common failure modes when this is not unified
Failure 1, Different recycled content numbers in different filings. UK PPT filing claims 32%; California SB 54 filing claims 28%. The numbers are inconsistent because the underlying data was collected separately under different definitions. The discrepancy is detectable in audit and indefensible without unified records.
Failure 2, Pre-consumer counted where it should not be. UK PPT counts pre-consumer; most US state mandates do not. A unified record without the post/pre split forces a choice: either count it everywhere (inflates US state claims) or count it nowhere (under-claims UK exemptions).
Failure 3, Mass balance methodology drift. PPWR and UK PPT may accept different mass balance methodologies. A claim certified under one scheme may not satisfy the other. Without methodology metadata, the producer cannot defend which claims went where.
Failure 4, Stale supplier declarations. A supplier letter from 2024 supports the 2025 filing. By 2026, the supplier site, the resin grade, or the methodology has changed. Without renewal tracking, the claim is technically defensible only because no one has checked.
What this means operationally
Build the supplier evidence workflow once. Make every supplier provide the full set of fields, regardless of which jurisdiction triggered the request. Track effective dates and renewal dates as first-class metadata. Run jurisdiction-specific outputs as views over the underlying record, not as separate spreadsheets.
The investment is in the supplier interaction and the data model. Once those are in place, adding the next jurisdiction is a mapping exercise.
What to do in 2026
- Inventory your current supplier evidence by what fields it actually contains. Most evidence collected for UK PPT lacks the pre-consumer/post-consumer split needed for US state mandates.
- Standardize the supplier declaration template to capture the full unified field set.
- Convert legacy point-in-time letters into effective-dated records with renewal cadence.
- Reconcile the recycled content numbers being filed across jurisdictions. Differences should reflect rule differences, not data quality.
How Packgine helps
Packgine maintains supplier evidence records once, with the post-consumer/pre-consumer split, methodology metadata, and effective dates required for every jurisdictional output. UK PPT exemptions, PPWR claims, and US state PCR filings all derive from the same underlying records. When a supplier or a regulation changes, the impact propagates automatically across all filings.
