The correct processing boundary is the narrowest one that can deliver the qualified product, collect cash and preserve a tested route into domestic lint conversion. A garment business does not need to own every stage from spinning to finishing on its first day. It does need to know which material transformation occurs, who controls each handover and where cash waits before an invoice is settled. GFT therefore proposes a cut, make, trim and finishing core, with spinning and knitting treated as optional partnered steps. No conversion partner or commercial commitment is asserted.
This choice separates two contributions that are often merged. Assembly can create domestic employment and manufacturing value using imported fabric. It cannot, by itself, count that fabric as Cameroonian lint transformed locally. In the OECD and FAO definition, cotton mill use is the transformation of cotton fibres by mills into yarn.[S29] The industrial question is therefore not how many stages appear on a project diagram. It is which additional stage improves accepted output and cash performance after its material losses, utility needs, environmental obligations and management burden are included.
Each proposed boundary should pass four tests. The product test establishes that a buyer accepts the resulting specification. The material test reconciles input, output, waste and origin. The operating test proves that people, utilities and partners can repeat the result. The cash test shows who finances stocks, conversion, rejects and receivables. A stage that fails any test should remain external, be remedied or stop, even if owning it would make an industrial map look more complete.

Garment assembly and lint transformation are different contributions
A material boundary begins with physical operations. Ginning separates lint from seed and cleaning can involve a trade-off between weight and quality.[S04]Spinning converts fibre into yarn. Fabric formation produces a woven or knitted structure. Wet processing can then wash, dye, print or finish that fabric before cutting, sewing, finishing and dispatch turn it into an accepted garment.[S02][S10][S29] These stages may occur in one company, across several companies or in different places. Their commercial ownership does not change their material sequence.
The distinction matters because a garment label can describe assembly geography while a national processing account describes fibre transformation. Imported cloth cut and sewn in Cameroon supports local assembly activity, but the cloth did not consume domestic lint. Domestic yarn knitted into fabric does consume lint, even if later sewing occurs elsewhere. OECD guidance on garment and footwear due diligence also directs attention beyond final assembly to company-specific risks across the supply chain, including subcontracting and materials.[S12] A credible operating model therefore records the assembly contribution and the fibre contribution separately rather than treating one as evidence of the other.
Exhibit 27 shows two launch routes that can produce garments while making different material claims. The imported-fabric route enters the model at cutting. The domestic-lint route enters at spinning and may use qualified external converters before the same cutting operation.
The flow prevents two accounting errors. First, garment dispatch must not be relabelled as domestic lint intake when the fabric was imported. Second, the same domestic lint must not be counted again as new national fibre transformation when yarn becomes fabric and fabric becomes a garment. Later stages can add value and change product form, but the national lint account needs one consistent first-conversion rule. Factory accounts can still record every internal transfer for cost and quality control.

7.2 The boundary record should follow each lot
7.2
GFT's proposed lot record carries material origin, supplier, weight and moisture basis at intake; conversion stage and responsible operator; output and measured loss; quality release; and the next custodian. The record closes only when the final product is accepted or the residual is assigned a verified destination. This is a measurement design, not a claim that a traceability system already operates.
¶ 05
The record also supports a commercial counterfactual. If a buyer would accept either imported or domestic fabric at the same specification, the sponsor can compare the two delivered costs and cash cycles without confusing a sourcing preference with a technical necessity. If the buyer requires domestic cotton content, the material record becomes part of product qualification. OECD due-diligence guidance makes company-specific risk identification necessary in either case; changing ownership of a stage does not remove the need to know its conditions.[S12]

7.3 · the bodyExhibit 28 above; its figures are illustrative where marked.
Partnering allows a garment operator to test domestic lint conversion without immediately owning every upstream asset. In the proposed base case, the operator controls product specification, cutting, assembly, finishing and buyer acceptance. A qualified spinner or fabric former converts traced material under agreed service terms. This is a design option within GFT's Cameroon textile programme, not a statement that any spinner, knitter or buyer has agreed to participate.
A partnership is an operating interface, not a verbal allocation of capacity. The sponsor needs evidence that the converter can hold a production slot, process the specified lot, meet the quality tolerance and return the agreed material within the delivery window. The contract must state title to lint, yarn, fabric and residues; permitted loss and how it is measured; responsibility for moisture change and contamination; packaging; insurance; rejection and rework; and payment timing. Historical analysis of Cameroon's cotton and textile chain identifies interdependent industrial and logistics constraints, so a converter's machine availability alone cannot establish a reliable service.[S02]
The quality protocol should begin before bulk conversion. A representative lint lot is sampled against the intended yarn specification. The converter records settings, output, waste and defects. The fabric route then tests whether that yarn performs in the intended construction. Acceptance belongs to the product specification, not to a generic claim that local cotton is suitable for every use. Ginning evidence already shows why cleaning and weight effects must be considered rather than assuming that every input unit becomes saleable output.[S04]
7.4 Make, buy and partner choices distribute risk rather than remove it
7.4
Purchasing fabric concentrates effort on assembly but leaves the buyer dependent on fabric quality, origin evidence and replenishment. Toll conversion retains material ownership and can support a domestic lint claim, but it adds handovers, stock at another site and exposure to the converter's queue. Owning a stage increases direct control over scheduling and process records while adding capital, maintenance, supervision and utility obligations. IFC's environmental and social management guidance similarly makes risk management an operating responsibility rather than a procurement label.[S24]
Exhibit 28 positions illustrative boundary options against external dependency and internal commitment. The coordinates are a discussion aid, not measured scores. Their purpose is to force each option to carry both sides of the trade-off.
The exhibit does not say that partnered conversion is always preferable. A partner without spare capacity, compatible equipment or reliable quality can be more disruptive than an owned line. Conversely, an owned line without sufficient orders can turn control into idle fixed cost. The correct comparison uses the same product lot and delivery requirement, then prices the complete service: conversion fee, transport, loss, inspection, inventory, financing and failure recovery. Missing evidence remains a cost risk, not a zero.
A small paid trial is more informative than a large framework discussion. It reveals whether the converter can reproduce the sample, whether material returns reconcile and whether the final buyer accepts the result. Repetition then tests scheduling and cash, not just technical possibility. Only after those records exist should the sponsor compare partnership with ownership at scale.

Spinning needs a matching yarn demand and reliable utilities
Spinning should enter the boundary only when a specified yarn has a credible destination. That destination may be a fabric operation within the same programme or an external fabric maker, but an internal transfer is not independent proof of demand. The commercial test begins with the fabric and final product, then works backwards to yarn construction, quality tolerance, order cadence and delivered cost. This follows the derived-demand relationship between cotton use and downstream textile products.[S29][S32]
The technical test is equally specific. Fibre trials must show whether represented lint lots can produce the required yarn at stable settings and acceptable waste. The resulting yarn must then pass the intended fabric process. A laboratory result without a production lot can miss variation between bales, while a single production lot cannot establish repeatability across supply periods. GFT would therefore preserve lot identity, trial conditions, accepted output and residual weights so that the yield claim remains attached to its evidence.
¶ 02
Exhibit 29 demonstrates why installed stages cannot be sized from final fabric demand alone. It uses a normalised illustrative lint input and assumed conversion yields. These values teach the accounting method and are not Cameroon mill benchmarks.

Illustrative normalised model. Assume 100 units of lint, 90 percent spinning yield and 95 percent fabric-formation yield. Yarn output is 100 x 0.90 = 90; fabric output is 90 x 0.95 = 85.5; losses are 10 and 4.5. Assumptions demonstrate reconciliation only and are not technical benchmarks. S04 supports attention to weight loss and S29 defines fibre transformation into yarn.

Utilities and maintenance can invalidate an otherwise sound material case. The IMF's February 2025 review describes Cameroon's electricity sector as structurally in shortfall.[S07] That national statement does not quantify any candidate mill's supply, but it prevents a sponsor from treating power as an unexamined constant. Spinning release requires a measured load profile, connection evidence, interruption and voltage records, restart-loss trials, critical spares and demonstrated maintenance coverage. Backup economics must include lost production and quality effects, not only energy price.
The release package also needs stock finance. Lint may wait before conversion, yarn may wait for fabric slots and rejected material may wait for disposition. A positive conversion margin calculated on accepted output can coexist with a cash deficit if those intervals are unfunded. The proceed condition is therefore a matching yarn outlet, repeatable lot results, maintainable equipment, credible utility supply and a financed material cycle. No spindle count or plant size is justified without them.

Fabric construction constrains the next stage
Weaving and knitting are not interchangeable capacity labels. Weaving interlaces warp and weft yarns, while knitting forms fabric through interlooping. The chosen garment and its performance specification determine which structure is relevant; the structure then shapes yarn requirements, machine settings, finishing and defect control.[S02][S12][S29] A national desire to process more lint cannot decide between them.
Consider candidate products rather than assumed orders. A stable woven workwear specification would direct trials towards a particular woven construction, seam performance and finish. A basic jersey product would direct them towards a knitted structure and its dimensional behaviour. These examples are diligence pathways, not evidence of buyer demand. They show why a fabric decision starts with the accepted end use rather than with whichever machine is available.
¶ 02
The order pattern matters as much as the construction. Frequent style, width, colour or gauge changes create setup work and learning time. Small batches can leave insufficient volume to absorb changeovers, while large batches can create greige or finished stock that the buyer has not yet accepted. Textile process guidance also links fabric preparation and finishing to quality and resource outcomes, so fabric formation cannot be specified without considering the subsequent process.[S10]
A numerical comparison requires vendor and trial evidence that is currently absent: the exact machine configuration; achievable rate on the intended construction rather than a catalogue maximum; setup and cleaning time; energy and air requirements; consumables; waste and downgrade rates; installation and building needs; spare-parts support; and the competence required on each shift. Output must be measured after quality acceptance. Until those inputs exist, claiming that weaving is always cheaper than knitting, or the reverse, would confuse equipment preference with product analysis.
¶ 04
The practical option is to qualify the fabric route through samples and paid production lots before purchasing a full line. External fabric trials can reveal yarn incompatibility, finishing defects and actual batch sizes while preserving the choice to partner later. If owned formation remains attractive, its business case should use the demonstrated construction and order pattern, not a generic textile utilisation assumption.
¶ 05
7.7 Trial records must separate machine possibility from accepted output
7.7
A fabric trial needs a common inspection boundary across purchased, partnered and owned routes. Record the construction and input yarn before the run, then reconcile greige output, finished output, downgraded material, rework and residual stock. Inspection should occur after the intended finishing route because a roll that appears acceptable before finishing may fail the buyer's dimensional or appearance requirement afterwards. Textile manufacturing guidance links process control to both quality and resource effects, so rejected fabric belongs in the material and cost calculation rather than in a separate operational footnote.[S10]
The trial record should also preserve the conditions under which the rate was achieved. A demonstration attended by a supplier's specialist does not establish that the proposed shift team can repeat it. Settings, operator support, stoppages, changeovers and maintenance interventions need to be visible. When comparing external and internal options, the sponsor should use the same acceptance rules and include transport and inspection time between stages. This prevents a high catalogue rate or a carefully selected sample from becoming an unsupported capacity assumption.

Wet processing changes the environmental and utility boundary
Adding dyeing, printing or finishing is not a simple extension of dry fabrication. It introduces process water, thermal energy, chemical storage and handling, wastewater treatment, sludge management and additional worker and community risks. The IFC textile guidelines address these manufacturing impacts and monitoring needs, while noting that their boundary excludes agriculture and polymer synthesis.[S10] The guidelines are a 2007 technical reference, not a Cameroon permit or evidence that any proposed facility complies.[S10]
This changes the investment question. An internal wet-processing operation needs credible dry-season water availability, applicable abstraction and discharge permissions, treatment designed for the actual chemistry, safe chemical handling, emergency arrangements and monitoring records. IFC Performance Standard 3 frames resource efficiency and pollution prevention as necessary responses to industrial pollution risk.[S26] Performance Standards 1 and 2 add management, consultation, grievance and worker-condition duties that cannot be delegated to equipment suppliers.[S24][S25]

A qualified external wet processor remains an alternative worth testing. Outsourcing can avoid immediate treatment and utility capital while providing process evidence, but it adds transport, batch queues, chain-of-custody handovers and dependence on another operator's environmental performance. OECD guidance expects a company to identify priority risks in its own circumstances, including those beyond final assembly.[S12] The sponsor therefore needs records of the external site's water and effluent controls, chemical practices, worker protection, lot identity and corrective actions. Sending material elsewhere does not make those questions irrelevant.
The comparison must use equivalent fabric quality and useful output. A shorter domestic route is not automatically a lower-impact route, and an integrated site is not automatically cleaner than a qualified external one. UNEP's value-chain roadmap warns that addressing production impacts alone is insufficient, which directs attention to the wider system rather than a single factory boundary.[S15] Transport saved by co-location may be offset by inefficient utilities, poor treatment or high rejection. The counterfactual must be stated before any sustainability claim is made.
Cash exposure also changes. Wet processing can impose minimum batch sizes, chemical purchases, treatment consumables, laboratory testing and longer rework loops. A failed shade or finish can hold the whole lot while additional water, heat and chemicals are consumed. The unit-cost model should therefore include compliant treatment, monitoring, rejects and downtime, with the timing of each cash payment visible. Omitting these items would make internal wet processing look cheaper by moving necessary costs outside the model.

Integration can improve control over scheduling, process settings and material records. It does not create demand or remove the underlying conversion cost. The sponsor exchanges dependence on an external converter for responsibility for capital works, maintenance, utilities, quality, environmental performance and a larger management span. The relevant comparison is not the partner's visible fee against the owner's visible operating cost. It is the complete cost and cash exposure per accepted unit under the same specification and delivery conditions.
A make, buy or partner review should start with the failure modes. Purchased or partnered input can arrive late, fail inspection or become unavailable when another customer takes the slot. An owned stage can suffer the same material problems while also carrying idle labour, spares, debt service and repair obligations. Direct control is valuable only when the organisation can detect and correct deviations. Otherwise, ownership can make a failure more expensive without making it less likely.
The financial boundary must also consolidate internal transfers. Lint sold to a spinner, yarn transferred to a fabric unit and fabric transferred to assembly are not three independent additions to national value. Within one venture, transfer prices help attribute performance but must be eliminated when assessing the whole operation. Within a national processing account, the first qualifying lint transformation is counted once while later value creation is assessed separately. This protects the decision from rewarding a longer chain merely because more invoices appear inside it.
The incremental investment question is narrower than a total chain comparison. Ask what changes if the next stage is added: saleable output, buyer acceptance, conversion loss, external fees avoided, internal operating cost, inventory, payment timing, capital expenditure and downside exposure. Continue to credit the existing garment operation only with what it can earn independently. A weak upstream stage should not be hidden inside a profitable assembly business, and a viable assembly business should not be forced to subsidise an unproven mill.
7.10 Cash can bind even when conversion appears cheaper
Every extra physical stage creates another place where material and cash can wait. Owned conversion may reduce an external service payment while increasing raw-material stock, work in progress, spares and fixed operating commitments. Partnered conversion may reduce fixed investment while requiring deposits, minimum lots or longer queues. Buying finished fabric may simplify the cycle while exposing the assembler to supplier credit terms and import replenishment. None of these routes is cash-light by definition.
This arithmetic gives the operations and finance teams a common variable: days between cash payment and cash recovery. Material trials should record those days at every handover, including inspection and dispute. The sponsor can then test whether integration shortens the cycle in practice or merely moves stock from a supplier's balance sheet to its own. That distinction is especially important where production ramps before buyers have established repeat payment behaviour.
Ownership becomes more credible when qualified demand is repetitive, external conversion fails the product or delivery requirement, and the internal stage can operate safely at a funded utilisation level with acceptable resource performance. Partnering remains preferable when volumes are uncertain, specialist competence is scarce or external service offers a better downside result. Buying remains sensible when the input is standard, qualified supply is competitive and domestic transformation of that input is not a necessary programme objective. These are conditional choices, not a fixed sequence towards maximum integration.

Expansion needs a repeatable stage-gate package
A repeatable gate prevents each new stage from being approved through a different story. The decision memo should present the same product, material, operating, environmental and cash evidence whether the proposal concerns assembly, spinning, fabric formation or wet processing. It should also identify what remains unknown and who must resolve it. IFC's management-system guidance supports consultation and grievance mechanisms as part of that operating discipline, rather than treating environmental and social review as a late permit attachment.[S24]
Exhibit 30 summarises the proposed package. Its release evidence is cumulative: an upstream stage cannot waive the buyer and cash evidence required by the existing operation.

Illustrative GFT gate design informed by the sources listed. It is a proposed decision framework, not an approved investment plan, current permit assessment or claim that evidence has already been obtained.
The table produces four legitimate outcomes. Proceed means the evidence supports the defined stage at the defined scale. Defer means a specific missing item must be resolved before reconsideration. Outsource means the product can continue through a qualified external route while ownership remains unproven. Stop means the stage fails its commercial, technical, cash or environmental and social case and should not be kept alive to preserve an integration narrative.

7.12 The gate must protect the viable operation from the proposed one
7.12
Decision rights should be explicit. The commercial role owns buyer evidence and acceptance. Operations owns process capability and maintenance. Finance owns the cash cycle and downside sensitivity. The environmental and social role owns impact review, consultation and corrective-action evidence. Worker-safety considerations belong in the operating release, consistent with the worker-management emphasis in IFC Performance Standard 2.[S25] An independent reviewer should challenge whether the evidence supports the proposed boundary rather than simply confirming that documents exist.
¶ 02 · 1 source
consistent with the worker-management emphasis in IFC Performance Standard 2S25
A failed upstream gate must have a contained consequence. If spinning does not meet its release conditions, the garment operation may continue with qualified purchased or partnered fabric, provided its own product and cash gates remain sound. If wet processing cannot demonstrate lawful and effective controls, finished fabric can be sourced externally while the site case is reconsidered. The programme's objective is retained value through viable production, not ownership of every process at any cost.
¶ 03
The same discipline creates a useful measurement history for the proposed cotton-value-flow and ramp-planner interfaces. cotton-value-flow would reconcile origin, transformation and loss at the selected boundary. ramp-planner would test whether accepted output and cash collection support the next release. These are proposed analytical interfaces, not evidence that the tools or an operating factory have been validated. Detailed production-flow, wet-processing and inventory methods remain with the companion specialist papers.
The strongest boundary is therefore conditional and reversible where practical. Early assembly builds product and workforce evidence. Partnered conversion tests the domestic-lint route. Owned spinning, fabric formation or wet processing enters only when its incremental evidence is stronger than the alternative. Expansion becomes a sequence of earned commitments rather than a single bet on a fully integrated chain.
