USDA allocates a share of the anticipated U.S. sugar market to sugar producers annually. This allotment basically determines the amount of sugar an individual company is allowed to sell that year. However, these allotments can be, and often are, adjusted based on harvest conditions.
Info. The United States (U.S.) is the fifth largest sugar producer and fifth largest consumer of sugar in the world. The U.S. sugar industry has enjoyed trade protection since 1789 when Congress enacted the first tariff against foreign-produced sugar. Since then, the U.S. government has continued to provide trade support and protection for its domestic sugar industry.
