All of the leading firms in food manufacturing and agricultural input industries are multinational, offering product sales spread across several continents. One indicator of the degree of globalization of agricultural input markets is the global distribution of agricultural input sales. In 2006, member countries of the North American Free Trade Agreement (NAFTA--United States, Canada, and Mexico) accounted for about 23 percent of the global seed market and 30-36 percent of global sales of agricultural chemicals, farm machinery, animal feed, and animal health pharmaceuticals (including those for nonfood animals). The Europe-Middle East-Africa market (which is mostly Europe) had the largest aggregate seed sales in 2006, whereas Asia-Pacific countries used the most fertilizers and bought the most farm machinery. Together, Asia-Pacific and Latin America are indicative of the developing-country share of global agricultural input markets. They account for 37-51 percent of global sales of crop seed and chemicals, farm machinery, fertilizers, and animal feed.
