Why Bangladesh's Costing Sheets Still Begin With Cotton: Fiscal Signals, the Man-Made Fibre Transition, and the Coordination Problem in Apparel Sourcing

Bangladesh built the world's second-largest apparel export industry on cotton, yet global apparel demand has shifted decisively toward man-made fibres (MMF). Roughly 70 per cent of Bangladesh's ready-made garment (RMG) exports remain cotton-based, while MMF apparel now accounts for a larger share of global apparel trade than cotton, and polyester alone represents well over half of world fibre production. This commentary examines that structural mismatch through a sourcing and merchandising lens, using the fiscal signals in Bangladesh's FY2026-27 national budget as its point of departure. The budget reduced value added tax on MMF yarn from Tk 6 to Tk 3 per kilogram, achieving parity with cotton yarn for the first time, while simultaneously proposing higher import duties on polyester staple fibre and PET resin, the basic raw materials of the synthetic value chain. Following industry objections, the PET resin duty was returned to its previous level in the passed Finance Bill, but the episode revealed an unresolved tension between protecting nascent domestic producers and lowering input costs for export diversification. The paper argues that the deeper obstacle is not any single tax rate but a coordination problem: manufacturers require credible long-term order commitments before investing in MMF capability, while buyers require demonstrated capability before committing long-term programmes. Drawing on documentary analysis of official publications, intergovernmental data, and trade reporting, the commentary situates this stand-off within Bangladesh's import dependence, its scheduled graduation from least developed country status in November 2026, and the competitive positions of China, Vietnam, and India. It distinguishes verified evidence from forward-looking analysis and sets out phased, actor-specific recommendations for brands, manufacturers, buying houses, sourcing teams, and policymakers.
