Traceability economics depend on the work needed to sustain it

Selecting a software vendor or ledger architecture before defining the claim boundary, identification granularity and partner exchange method reverses the engineering sequence and locks the factory into unnecessary recurring costs.[S10][S12][S27] A traceability platform is an infrastructure layer for storing and exchanging custody observations; it cannot determine whether batch or serial tracking is physically observable on the spinning floor, nor can it substitute for missing upstream certificates.[S01][S10][S25]

Before issuing a request for proposals, GFT's build-or-buy methodology requires the sponsor to fix three architectural scope choices derived from Chapters 5, 8, 9 and 10.[S10][S12][S27]

Identification granularity (product model, production batch or serialised item): Under GS1 Digital Link URI syntax (Release 1.7.0, ratified August 2026) and the working UNECE / UN Transparency Protocol (UNTP) Digital Product Passport specification, identifiers can resolve at the product class level, the batch or lot level, or the unique serialised item level.[S12][S28] Because cotton bales are blended in spinning laydowns and fabric rolls are grouped in cutting lays, upstream provenance is physically bounded at the batch or campaign level; applying unit-level radio-frequency identification (RFID) or serialised QR tags to individual garments cannot create farm-level precision upstream, and EPCIS 2.0 explicitly does not require RFID.[S02][S10][S12] Choosing batch-level tracking for pilot evaluation avoids the recurring consumable and scanning cost of item-level serialisation unless a buyer contract specifically funds item-level anti-counterfeiting controls.[S10][S12]

Partner data exchange mode (controlled file templates versus automated APIs): While GS1 EPCIS 2.0 and Core Business Vocabulary (CBV) 2.0 support real-time capture and query interfaces, many ginneries, cooperatives, warehouses and commission finishers in West and Central Africa operate periodic accounting systems or face intermittent connectivity.[S10][S11] A practical system must therefore accept validated flat-file or spreadsheet uploads that map cleanly to EPCIS event fields and preserve cryptographic hashes of attached PDFs (such as weighbridge tickets and transaction certificates), rather than requiring every upstream partner to purchase an enterprise API connector.[S03][S10]

Hosting and ledger model (managed database, self-hosted repository or permissioned shared ledger): NIST IR 8202 explains how blockchain technology provides tamper-evident distributed ledgers, while NIST SP 800-161 Rev. 1 (updated November 2024) emphasises assessing cybersecurity and continuity risks across software and service supply chains.[S25][S27] As shown in Chapter 10, ledger immutability prevents silent retroactive alteration of a stored record, but it cannot verify that a physical bale weighed at a ginnery matched the number typed into the terminal, and an immutable ledger still requires an explicit EPCIS error-declaration workflow when human entry mistakes occur.[S10][S25] Similarly, whether verifiable credentials follow the W3C Verifiable Credentials Data Model v2.0, W3C Decentralized Identifiers (DIDs) v1.0, W3C Bitstring Status List v1.0 and the March 2026 W3C Verifiable Credentials Use Cases Note, or whether records are held in a conventional relational database with signed exports, depends on whether multiple untrusting parties need decentralised verification, rather than on marketing claims that a blockchain reduces audit costs.[S21][S22][S24][S1202]

When a garment manufacturer places its custody records and product passport URLs inside a proprietary software-as-a-service (SaaS) platform, vendor lock-in becomes a direct threat to commercial continuity.[S13][S27] Under the European Commission's Ecodesign for Sustainable Products Regulation (ESPR) implementation process, textile-specific Digital Product Passport fields remain to be defined through future delegated acts (with adoption of the textile delegated act indicatively planned for Q4 2027 as of the research cutoff), meaning that data schemas and disclosure rules will evolve over coming years.[S14] If a vendor controls the domain name printed on garment labels, stores events in an undocumented format, holds the private cryptographic signing keys without customer recovery rights, or charges punitive fees to export historical evidence, switching providers can invalidate years of issued product identifiers and audit trails.[S12][S13][S27]

To prevent lock-in, GFT evaluates candidate platforms and internal build options against the qualitative acceptance criteria in Exhibit 54, requiring executable proof during procurement rather than sales assurances.[S10][S13][S27]

Every row in Exhibit 54 translates a technical standard into a contractual and operational gate.[S10][S13][S27] Under GS1-Conformant Resolver Standard Release 1.2.1 (ratified August 2026), a conformant resolver publishes a machine-readable description file and routes requests across link types; by keeping the top-level domain or subdomain under the manufacturer's or brand's own DNS control and requiring a full export of the resolver routing table, the enterprise can redirect existing garment QR codes to a new host if a software contract ends.[S12][S13] Similarly, requiring bulk export of all EPCIS 2.0 events, UNTP Digital Traceability Events (DTEs) or Conformity Credentials, and linked PDF evidence files, and testing that export by restoring it onto an independent staging environment under NIST SP 800-161 Rev. 1 supply-chain continuity principles, ensures that historical custody records survive vendor insolvency or price increases.[S10][S27][S29][S30] Notice that Exhibit 54 assigns no synthetic points or market-share rankings to named software vendors; GFT has not benchmarked commercial providers in Cameroon, and procurement acceptance depends solely on passing these functional verification tests.[S27][S1201]

A traceability system that appears profitable on a brand's or garment exporter's income statement can still fail operationally if it shifts uncompensated capture, segregation and administrative work onto upstream farmers, producer groups, ginneries and domestic subcontractors.[S06][S17] In multi-tier cotton chains, the actors nearest the raw material often face the tightest working-capital constraints and the highest transaction count per tonne of fibre, while the commercial reward for a verified origin claim accrues at the final brand or export invoice.[R03][S17]

Tracing cotton from northern Cameroon's production zone through ginning, spinning, fabric processing and garment assembly distributes distinct operational burdens across four tiers of participants.[R03][S06]

Smallholder producers and producer groups: Collecting delivery receipts, verifying group membership, maintaining clean harvest bags to prevent contamination, and consenting to personal-data processing impose time and coordination costs at the village collection point.[S06][S19] While inherited evidence notes that SODECOTON supports more than 220,000 cotton producers and injects roughly US$100 million a year into rural communities, individual smallholders cannot be assumed to own smartphones, maintain continuous data connectivity or absorb unpaid administrative form-filling without risking exclusion of smaller farms.[R03][R04][S17] Furthermore, as the European Data Protection Board (EDPB) small-business guidance states, an organisation may process only personal data that is necessary and proportionate for the envisaged purpose; demanding excessive farm-level personal identifiers raises both compliance costs and privacy risks without improving batch-level cotton provenance.[S19]

Ginneries and lint warehouses: Under the Aid by Trade Foundation Transparency Standard, keeping eligible seed cotton and ginned lint bales physically or temporally separated from conventional material, cleaning gin stands between campaigns, tagging every bale and registering shipments in tracking portals such as the Sustainable Cotton Tracker (SCOT) require dedicated warehouse space, campaign scheduling and clerical verification.[S06][S09] Notice that SCOT's operational FAQ explicitly states that SCOT is not an order system; counterparties must therefore maintain tracking confirmations alongside their ordinary commercial invoicing.[S09]

Spinners, weavers, dyers and toll subcontractors: Maintaining batch genealogy across bale laydowns, yarn lots, greige fabric rolls and dye batches requires smaller lot runs, more frequent line changeovers and explicit subcontractor tally sheets.[S03][S06][S10] When a garment maker serves three different international buyers who each demand a different spreadsheet template or proprietary portal login for the same physical custody events, clerical entry time multiplies without adding a single new physical observation.[S10][S1201]

Garment manufacturer and brand claimant: The downstream claimant bears the cost of final cutting-lay allocation, passport publication, customer-facing resolver maintenance and legal accountability for the public claim, while holding the direct commercial relationship with the institutional buyer or retail market.[S13][S14][S28] The OECD Due Diligence Guidance for Responsible Supply Chains in the Garment and Footwear Sector emphasises collaborative, constructive approaches across supply chains rather than shifting compliance burdens unilaterally onto upstream suppliers.[S17] Equally, as the International Labour Organization (ILO) definition of forced labour underscores, labour due diligence concerns coercion and voluntariness across formal and informal work arrangements; paying for a fibre-tracking software licence neither compensates upstream workers nor substitutes for independent labour risk assessment and remediation.[S17][S20]

To prevent supplier fatigue and smallholder exclusion, GFT proposes an operational cost-allocation schedule and a shared-data contract architecture across the supply chain.[S06][S10][S17] At the producer group and first-collection tier, pseudonymous delivery receipt capture, bag marking and privacy-compliant group roster maintenance are funded by the downstream programme or managing entity through field-agent capture support and direct service fees, with zero software fees charged to farmers.[S06][S17][S19] At the ginnery and lint storage tier, campaign segregation, bale tagging, moisture and tare logging, and dispatch confirmation are compensated through an explicit per-bale handling and documentation supplement in the lint procurement schedule, audited against matched receipt packs.[S03][S06][S09] At spinning, fabric and wet-processing mills, transformation event logging, roll-splitting records, subcontractor tracking and volume reconciliation are governed by a capture-once shared-data clause so the supplier records one canonical EPCIS 2.0 and CBV 2.0 event stream and exports buyer-specific views without duplicate manual entry.[S03][S10][S11] At the garment exporter and brand tier, claim-card definition, final batch release review, third-party assurance fees and passport hosting are borne by the commercial claimant, with transaction certificate and assay costs shared according to contracted order volume.[S05][S14][S1201]
