Key terms from the world of textile and fashion traceability.
The ability to identify and track the history, distribution, location, and application of products, parts, and materials throughout the entire supply chain, from raw material sourcing to the end consumer. Traceability enables the verification of sustainability claims by providing information about the origins, processes, and practices involved in the production of goods.
The voluntary sharing of information related to the social, environmental, and economic aspects of a company's operations with relevant stakeholders, such as suppliers, customers, regulators, and the general public. Transparency involves disclosing information that is relevant, accurate, timely, and accessible to facilitate informed decision-making and promote accountability.
The pursuit of social, environmental, and economic objectives in a balanced and integrated manner, ensuring the long-term viability and resilience of the fashion-apparel supply chain. Sustainability encompasses practices and strategies aimed at reducing negative impacts, fostering ethical business practices, and promoting resource efficiency and circularity throughout the supply chain.
Any filament, fibre, or yarn that can be made into fabric or cloth, and the resulting material itself. The term is derived from the Latin textilis and the French texere, meaning “to weave,” and it originally referred only to woven fabrics. It has, however, come to include fabrics produced by other methods. Thus, threads, cords, ropes, braids, lace, embroidery, nets, and fabrics made by weaving, knitting, bonding, felting, or tufting are textiles.
A tiered value chain represents a hierarchical categorisation of the various intermediaries and processes involved in the production, distribution, utilisation, and end-of-life management of a product. This framework facilitates the assessment of traceability and visibility throughout the product's lifecycle. Although the tier concept is not standardised, it offers a simplified depiction of the different and numerous stages. Actual value chains can be highly complex, with numerous intermediaries and sub-processes within each tier, as well as multiple components and materials in a single product. The tiered structure aims to improve comprehension and support informed decision-making in value chain management.
The tiers are generally categorised as follows:
The upstream part of the value chain include:
Tier 4: Raw material agriculture, farming, and extraction
Tier 3: Raw material processing
Tier 2: Material manufacturing
Tier 1: Final product manufacturing
Tier 0: Distribution
The downstream part of the value chain (essential for a transition to a circular economy) include:
Tier +1: Use
Tier +2: End of life
In practice, the tiered structure represents a complex network with numerous branches, highlighting the intricacy of modern value chains.
A structured set of product-level data, accessible via a data carrier (typically a QR code or NFC tag attached to the article), that follows a product through its life and discloses information about its composition, origin, environmental footprint, repairability, recyclability, and compliance status. Under the EU Ecodesign for Sustainable Products Regulation (ESPR, Regulation (EU) 2024/1781), Digital Product Passports will become mandatory for product groups designated by delegated acts. Textiles, apparel, and footwear are among the first priority groups, with application expected around 2027–2028. A DPP is not a single technology but a data discipline: brands must collect and verify the required attributes across multiple suppliers before any data carrier can be issued.
Regulation (EU) 2024/1781, which entered into force on 18 July 2024, replacing the previous Ecodesign Directive 2009/125/EC and substantially expanding its scope. The ESPR sets a framework for product-level ecodesign requirements — durability, reparability, recyclability, recycled content, presence of substances of concern, environmental footprint — and introduces the Digital Product Passport as the mechanism for disclosing those attributes. Detailed requirements per product group are set in delegated acts adopted by the European Commission; textiles and apparel are included in the first ESPR working plan. The ESPR also bans the destruction of unsold consumer goods, with a phased application for textiles.
A legally binding act adopted by the European Commission that supplements or amends a non-essential element of a base regulation, in this case the ESPR. For the Digital Product Passport, each product group receives its own delegated act specifying the data attributes a DPP must carry, the verification methods, the data carrier format, and the timeline. The textile delegated act, first of the priority groups, is in preparation by the Joint Research Centre (JRC) and the European Commission; a JRC Preparatory Study and a Methodology Report were published in 2024 and 2025, with adoption expected in the near term and application around 2027–2028. The exact schedule is the single most important variable for brand DPP planning.
Directive (EU) 2022/2464, which obliges large EU companies and EU-listed SMEs to report sustainability information according to the European Sustainability Reporting Standards (ESRS). For fashion brands above the CSRD thresholds, the standards covering environment (E1–E5), workforce in the value chain (S2), and consumers (S4) require traceability data that overlaps substantially with the data the ESPR will require for the Digital Product Passport. CSRD reporting is at the company and group level; DPP disclosure is at the product (SKU) level — both depend on the same underlying supplier data, which is why traceability work undertaken for one usually accelerates compliance with the other. The first wave of CSRD reports was published in 2025 for financial year 2024.
A binding obligation, set out in Directive (EU) 2024/1760 (Corporate Sustainability Due Diligence Directive, CSDDD), for in-scope companies to identify, prevent, mitigate, and account for actual and potential adverse human-rights and environmental impacts arising from their own operations, their subsidiaries, and their chains of activity. For fashion, the chain of activity extends from raw-material extraction through final manufacturing and into downstream distribution. The CSDDD entered into force on 25 July 2024 with phased application starting in 2027 for the largest companies. Earlier national instruments — France's loi sur le devoir de vigilance (2017) and Germany's Lieferkettengesetz (2023) — already imposed similar duties and remain in force.
The French loi n° 2020-105 relative à la lutte contre le gaspillage et à l'économie circulaire (Anti-Waste Law for a Circular Economy), adopted on 10 February 2020. Article 13 introduced a product-level fiche d'information environnementale requirement for textile articles sold in France, covering recycled content, country of fabrication for several supply-chain stages, presence of hazardous substances, and microfibre release for synthetic textiles. AGEC pre-dates and partially anticipates the ESPR Digital Product Passport for textiles; brands selling on the French market have, in effect, already been required to publish a subset of DPP data points since 2023.
A standardised European life-cycle assessment methodology developed by the European Commission's Joint Research Centre, used to measure a product's environmental performance across multiple impact categories (climate change, water use, land use, resource depletion, toxicity, and others). For apparel and footwear, sector-specific rules are set out in the Product Environmental Footprint Category Rules (PEFCR) for Apparel and Footwear, finalised in 2025. The PEFCR is expected to be the reference methodology for the environmental data points required by the ESPR textile delegated act. PEF results are not directly comparable to other LCA methodologies (ISO 14040/14044, GHG Protocol) and require sector-specific datasets that many brands do not yet have on file.
Under the ESPR, a substance that: (a) meets the criteria laid down in Article 57 of REACH and is identified under Article 59(1) (Substances of Very High Concern, SVHC); or (b) is otherwise classified as hazardous under Regulation (EC) No 1272/2008 (CLP); or (c) negatively affects the re-use and recycling of materials in the product. The Digital Product Passport must declare the presence of substances of concern above the relevant thresholds. For textiles, this includes a long-running list of chemicals already restricted under REACH Annex XVII (azo dyes, phthalates, certain perfluorinated compounds among others) and a wider set of substances flagged for downstream recyclability concerns.
The shedding of small (under 5 mm) textile fibres from a garment or fabric during manufacturing, use, and end-of-life. Synthetic microfibres are one of the dominant sources of primary microplastic pollution in the ocean; natural-fibre microfibres also contribute to terrestrial and aquatic loads. Several EU instruments now require microfibre data at the product level: France's AGEC law has required a microfibre-shedding indicator on synthetic textiles since 2023, and the ESPR textile delegated act is expected to introduce a harmonised test method (likely the ISO 4484 family) and a DPP disclosure obligation.
A documented system that records the transfer of ownership, custody, and physical handling of a product or material at every stage of its journey through the supply chain. A chain-of-custody scheme is what makes a traceability claim verifiable: it links the certified raw material at Tier 4 to the finished article sold to the consumer. The four most-used models are identity-preserved (the certified material is kept physically separate at every stage), segregated (separate from non-certified material but mixed across certified sources), mass balance (certified and non-certified material can be mixed, but certified output volumes cannot exceed certified input volumes), and book-and-claim (certificate trading detached from physical flow). The DPP framework favours the first three; book-and-claim is more contested.
A chain-of-custody model in which certified and non-certified inputs to a production process may be physically mixed, on condition that the volume of certified output sold downstream does not exceed the volume of certified input bought. Mass balance is the dominant model for materials where physical segregation is uneconomic — chemical recycling, some biomass-derived polymers, occasionally fibre-to-fibre recycled cotton — because it preserves the certification claim without requiring parallel production lines. Mass balance is contested: the certified fibre that a consumer believes is in their garment may not, physically, be there at all. Whether mass-balance claims will satisfy DPP requirements depends on the specific delegated act and on the integrity of the underlying scheme.
The proportion, by mass, of recycled material in a product or component. Under the ESPR, declared recycled content will become a mandatory DPP data point for most textile categories, with verifiable rules on the boundary between pre-consumer (industrial scrap recovered before reaching a consumer) and post-consumer (waste collected from end users after use) recycled material. Verification today most commonly relies on chain-of-custody certifications such as the Global Recycled Standard (GRS), the Recycled Claim Standard (RCS), or the Recycled Polyester Certification, but the ESPR delegated acts may introduce more prescriptive measurement methods.
The combined operational, financial, and human cost imposed on supplier factories that have to host multiple, partially overlapping audits — from different brand customers, different certification schemes, and different regulators — within short windows. Audit fatigue is widely documented in the multi-tier garment supply chain, where a single facility may host 30 or more audits per year, each with substantial preparation costs and lost production time. The fragmentation of audit frameworks is one of the structural reasons traceability data quality remains uneven across the fashion sector, and one of the driving arguments for the convergence efforts behind the ESPR and the Digital Product Passport.
A textile certification standard developed by four member organisations (IVN, JOCA, OTA, Soil Association) that defines requirements at every processing stage — from organic-fibre harvest through final manufacturing — for a textile product to be labelled as organic. GOTS covers fibre composition (minimum 70% certified organic fibres for the "made with organic" label, minimum 95% for "organic"), restricted chemicals at processing, social criteria across the supply chain (based on ILO conventions), and a third-party chain-of-custody verification. GOTS is widely used in EU markets and is one of the more credible references for DPP-grade traceability data on organic-cotton claims.
A textile-product certification, issued by the international OEKO-TEX association, that verifies tested articles are free from a defined list of harmful substances above specified thresholds. The standard covers chemicals regulated under REACH Annex XVII and others on OEKO-TEX's own list, updated annually. STANDARD 100 is the most widely cited textile chemical-safety certification in fashion DPP discussions, but it covers product-level testing only — it does not verify environmental management, social conditions, or supply-chain origin. Complementary certifications (such as STeP for facility management or MADE IN GREEN for traceability) sit alongside STANDARD 100 in the OEKO-TEX system.
