External data can bound a market but cannot nominate a winner

A customs import table records border crossings of classified merchandise, not retail demand. When a planning team extracts apparel import series from the United Nations Comtrade database, it observes data sourced directly from national authorities and submitted to the United Nations Statistics Division under international merchandise trade conventions.[S41] Those records capture formal consignments declared at customs ports. They do not record garments produced and sold by domestic tailors, stock held in wholesale warehouses between seasons, unrecorded cross-border trade, or the date and price at which a final consumer buys an item. Treating an annual or monthly customs inflow as a direct proxy for retail sell-through confuses wholesale supply entering a territory with consumer demand clearing at the point of sale.[S06][S41]

4.2 Customs classifications aggregate heterogeneous garments and channels

International trade platforms organise apparel flows primarily under Harmonized System (HS) Chapter 61 (articles of apparel and clothing accessories, knitted or crocheted) and Chapter 62 (articles of apparel and clothing accessories, not knitted or crocheted), alongside Chapter 63 for other made-up textile articles and worn clothing. The International Trade Centre (ITC) Trade Map system provides both values and quantities for the trade flows of goods across these tariff headings.[S43] Even at the six-digit subheading level, a single customs line groups garments that differ in silhouette, fabric weight, stitch density, branding, sizing, retail channel and target occasion. New-item forecasting research demonstrates that clothing and footwear demand depends on fine-grained merchandising attributes, selling price, product age and store context.[S02][S03] Because a customs declaration strips away those merchandising attributes, a six-digit HS flow can bound the volume of a broad category entering formal distribution, but it cannot identify which design attributes or price points will win inside that category.[S02][S43]

Market context in Cameroon illustrates why channel and product boundaries must remain explicit before any trade series touches a forecast prior. Inherited sector evidence records that Cameroon's domestic textile player CICAM saw its domestic market share fall from about 85 percent three decades ago to about 5 percent in the baseline period, while informal employment accounts for about 90 percent of total employment across the economy.[R11][R16] At the consumer level, inherited market estimates put Cameroon clothing and footwear expenditure at about US$94.70 a person in 2024, corresponding to about 8.0 pieces a person, while domestic apparel eCommerce revenue was estimated at US$20.32 million in 2023 and projected to reach US$33.61 million by 2027 at an annual growth rate of 13.41 percent.[R26] Each figure describes a different boundary: total personal expenditure, physical piece intake, formal online channel revenue, or domestic mill share. None is identical to customs-reported imports under HS Chapters 61 and 62, and none measures the sell-through velocity of a newly launched local garment line.[R11][R26][S41]

Exhibit 16 contrasts these distinct channel and customs buckets on a common monetary scale, joining the sourced 2023 Cameroon apparel eCommerce baseline with illustrative customs and informal inflow slices to show why an analyst must decompose category supply before setting a market bound.

Exhibit 16 establishes a foundational rule for Part I of the workflow: the largest volume entering a clothing market may sit in worn clothing or informal distribution rather than formal new-apparel customs lines, and even formal HS 61 and HS 62 lines represent landed wholesale shipments rather than consumer purchases.[R16][S41][S43] The exhibit cannot establish addressable demand for a specific Cameroonian factory offer; instead, it forces the commercial team to specify which customs headings, price tiers and distribution channels its proposed garment contests.

4.3 Policy and regional trade rules alter supply ceilings without guaranteeing sales

Trade series also reflect tariff regimes and preferential access rules. In the inherited register, Cameroon's eligibility under the United States African Growth and Opportunity Act (AGOA) was terminated effective 1 January 2020 and remained listed as ineligible for calendar year 2025.[R18] Within Africa, textiles and clothing remained among unresolved tariff categories under the African Continental Free Trade Area (AfCFTA), where 92.3 percent of lines had been agreed excluding vehicles, textiles and clothing.[R23] Continental market-research sources in the register estimate the Africa textile market at about US$37.3 billion in 2025, projected to reach US$49.41 billion by 2030 at 4.73 percent a year in one series, and projected to reach US$72.7 billion by 2035 at 6.9 percent a year with fashion and apparel representing 48.1 percent of the 2024 market in a second vendor series.[R24][R25]

A cold-start team treats these vendor projections and trade-policy rules as scenario boundaries rather than model inputs.[S08][S0403] Vendor market-size reports carry grade-C status and use incompatible definitions, so GFT retains both series without averaging them.[R24][R25] Tariff-line resolution or preferential access changes the competitive ceiling of an export channel, belonging in conditional scenarios rather than in the statistical prior for domestic weekly sell-through.[R18][R23][S08]
