Fast-Moving Consumer Goods (FMCG) supply chains rely heavily on cross-border agreements that determine tariff regimes, non-tariff barriers, customs procedures, regulatory standards, supply chain mobility, and market entry strategies. International trade agreements influence not only cost structures but also product availability, packaging compliance, shelf-life logistics, and localization requirements. This paper synthesizes literature from trade economics, global value chain theory, consumer goods distribution, and international regulatory governance to propose the Trade-Driven FMCG Flow Framework (T-FMCGF). The model identifies five determinants: Tariff Structures, Standards Harmonization, Trade Facilitation Policies, Regional Value Chains, and Digital Trade Protocols. The study also compares FMCG flows under frameworks such as WTO, RCEP, EU Single Market, USMCA, AfCFTA, and ASEAN FTA
