Lysine prices are highly sensitive to the cost of raw materials, primarily corn starch and liquid ammonia, which are used in the fermentation process. Additionally, energy costs in the manufacturing region and environmental protection policies (which can lead to temporary factory shutdowns) play a major role. Buyers should monitor the global soybean meal market, as Lysine is often used as a cost-effective substitute for protein in animal diets; when soybean prices rise, Lysine demand and prices typically follow.
