Material Composition Under ESPR: What Textile Brands Must Actually Disclose
A technical breakdown of fiber declarations, percentage thresholds, and recycled content requirements in the EU's Ecodesign for Sustainable Products Regulation.
- The ESPR requires **machine-readable fiber composition** linked to each product's Digital Product Passport, going beyond current labelling rules.
- Fiber percentages must be declared down to **specific thresholds**, with "minor fibers" aggregated only when below defined limits.
- Recycled content claims require **chain-of-custody documentation** and will eventually need third-party verification.
- Material data must be **updatable and versioned** — a static PDF or sewn-in label no longer suffices.
- The delegated act for textiles is expected in 2025, with enforcement likely from mid-2027.
Beyond the Sewn-In Label#
For decades, textile composition disclosure meant one thing: a small label stitched inside the garment listing fibers and percentages. The EU Textile Labelling Regulation (No 1007/2011) established the rules — fibers above 2% must be named, the rest can be grouped as "other fibers."
The Ecodesign for Sustainable Products Regulation (EU 2024/1781) changes the game. Material composition is no longer just consumer information — it becomes structured data within the Digital Product Passport, accessible to regulators, recyclers, and the entire value chain (European Commission, 2024).
This shift has concrete implications for how brands collect, verify, and transmit fiber data.
What the ESPR Actually Requires#
The ESPR framework regulation establishes the architecture; the specific requirements come through delegated acts per product category. For textiles, the Commission has signaled that material composition will include:
| Requirement | Current (Reg. 1007/2011) | Under ESPR |
|---|---|---|
| Fiber names | Standardized EU terms | ISO 2076 codes + EU terms |
| Percentage precision | Integer %, ±3% tolerance | Exact %, tolerance TBD |
| Recycled content | Voluntary claim | Mandatory field if claimed |
| Data format | Physical label | Machine-readable (JSON-LD) |
| Accessibility | Garment only | Digital Product Passport |
| Updatability | Static | Versioned, auditable |

The key change: composition data must be interoperable. A recycler in Germany scanning a QR code on an Italian-made garment must retrieve structured data they can feed directly into sorting systems.
Fiber Declaration: The Technical Details#
Naming Conventions
The ESPR aligns with international standards. Expect fiber identification to require:
- ISO 2076:2021 generic names (e.g., "polyester" not brand names like "Dacron")
- CAS numbers for chemical identification where applicable
- Harmonized codes for novel fibers not yet in Regulation 1007/2011
Percentage Thresholds
Current rules allow "other fibers" aggregation for fibers under 2%. The ESPR delegated act is expected to tighten this for recyclability purposes. Draft discussions suggest:
- Fibers ≥ 1% by weight: individual declaration required
- Fibers < 1%: may be aggregated, but total must be stated
- Coatings, finishes, membranes: separate declaration if > 5% of product weight
(European Commission, DG GROW stakeholder consultation, 2024)
Recycled Content: Proof Required#
Claiming "30% recycled polyester" on a label today requires minimal documentation. Under the ESPR, recycled content becomes a verified data point with specific requirements:
- Definition alignment: "Recycled" must match ISO 14021 (pre-consumer vs. post-consumer distinction)
- Chain of custody: Documentation from feedstock to final product
- Mass balance rules: How blended recycled/virgin materials are allocated
- Verification: Self-declaration initially; third-party certification likely required by 2028
The Commission has indicated that recycled content claims without traceable documentation will be treated as non-compliant — not merely unverified (European Commission, Green Claims Directive proposal, 2023).
The Versioning Problem#
Here's what many brands overlook: DPP data must be updatable. If a supplier corrects a fiber percentage after production, or recycled content certification is later revoked, the passport must reflect this — with an audit trail.
This means:
- Static exports (PDFs, spreadsheets) are insufficient
- Data systems must support versioning with timestamps
- Corrections must be transparent, not silent overwrites
Frequently asked questions
Does ESPR replace the current textile labelling regulation?
No. Regulation 1007/2011 remains in force for physical labels. The ESPR adds a digital layer — the DPP — with more granular, machine-readable data. Brands must comply with both.
When do these requirements take effect?
The ESPR entered into force in July 2024. The delegated act for textiles is expected in 2025, with an implementation period of 18–24 months. Most analysts expect enforcement from mid-2027 (European Commission, ESPR implementation roadmap, 2024).
What if my suppliers can't provide this data?
This is the operational challenge. Brands will need to either upgrade supplier requirements or find alternative sourcing. The regulation creates strong incentives for vertical integration and supplier consolidation — a structural shift already underway.
Material composition might seem like a solved problem — after all, brands have been labelling garments for decades. But the ESPR transforms composition from a compliance checkbox into a data infrastructure challenge: structured, verified, versioned, and machine-readable.
Trama builds the data layer that makes this practical — extracting composition data from existing product information, structuring it to ESPR specifications, and keeping it audit-ready as requirements evolve. Because the hard part isn't knowing your materials. It's proving it, at scale, to a machine.
