The article outlines the expected impact of the EU-Mercosur agreement on the animal production sector in the EU, particularly in Poland. It focuses on the liberalization of customs duties for certain products from Mercosur countries, such as poultry, beef, and pork, with tariff quotas set for each. These quotas will gradually increase over six years, and imports exceeding the quotas will face the same customs duties as currently. The agreement also includes other sensitive animal products like milk powder, cheeses, and egg products, with some exceptions. Despite concerns, it is emphasized that beef from Mercosur countries will not significantly flood the Polish market, but may potentially hinder Polish exports within the EU. The article also stresses the importance of products meeting EU safety and quality requirements for access to the EU market.
