Purpose: The aim of the study was to evaluate impact of trade policies, tariffs, and sanitary and phytosanitary regulations on international livestock trade and market access for livestock producers in Brazil. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: it's evident that trade policies, including tariffs and non-tariff measures, significantly influence bilateral trade flows in livestock products. Reductions in tariffs generally lead to increased trade, while increases in tariffs have the opposite effect, demonstrating the importance of tariff liberalization for stimulating trade and enhancing market access. Unique Contribution to Theory, Practice and Policy: Theory of comparative advantage & new trade theory may be used to anchor future studies on impact of trade policies, tariffs, and sanitary and phytosanitary regulations on international livestock trade and market access for livestock producers in Brazil. Enhance capacity-building initiatives and technical assistance programs for developing countries to improve SPS compliance and facilitate trade in livestock products, thereby promoting inclusive trade practices. Negotiate comprehensive regional trade agreements (RTAs) that address trade facilitation measures, infrastructure development, and regulatory harmonization to maximize the benefits of market integration for the livestock sector.
