In 2013-2015, Chinese feed vitamin production is expected to be around 220,000-280,000 tons, with exports occupying 75-80 percent of that figure, according to reports. China has become an important global vitamin-producing and -consuming country, and in recent years exports have accounted for about 80 percent of the total output. In 2012, China produced 240,000 tons of vitamins, including exports of 187,000 tons.

So far, there have been more than 220 types of approved additives in China, including nearly 70 domestic types with standards and 57 types of allowed medicated additives. In 2011-2012, China's additive premix remained between 6.1-6.4 million tons. By type, amino acids, vitamins, medicated additives and biological enzymes account for a high proportion of the feed additives market, up to 80 percent and more, according to reports.

With respect to the amino acid feed additives segment, as China gives priority to pig and poultry breeding, coupled with restricted level of feeding, the actual consumption structure of feed amino acids is oriented by methionine and lysine. In 2012, China's lysine production and consumption were 855,000 tons and 610,000 tons, respectively, showing overcapacity and market competition. But limited by technical barriers, only one local enterprise - Chongqing Unisplendour Chemical Co. Ltd. - had realized methionine industrialization by the end of 2012. In 2012, China consumed 194,000 tons of methionine, including imports of 183,000 tons

In terms of the medicated additives segment, although Europe, the U.S. and other developed countries have already exercised strict control over the production and application of antibiotic drugs in feed, the proportion is still high in China. Feed-grade chlortetracycline (FG CTC) is one of them. In 2012 the world's overall production capacity of FG CTC reached 100,000 tons/a, of which China-based Jinhe Biotechnology Co. Ltd., Zhumadian Huazhong Chia Tai Co. Ltd. and Pucheng Zhengda Biochemistry Co. Ltd. accounted for roughly 85 percent.
