The products in question are marketed as ALIMET and MHA worldwide.
The price hike is effective immediately, said Novus.
All existing contracts will be honored, it added.
A spokeswoman for Novus, which manufactures both its dry and liquid methionine sources in the US, told us price fluctuations are not uncommon in the methionine industry.
"Today’s industry-wide low prices are not sustainable to meet the growing global demand for animal protein. HMTBa, found in Novus’s ALIMET and MHA feed supplements, continues to be the methionine source of choice for many of the world’s leading protein producers, and the market is growing."
Last month saw German chemical group, Evonik, raise the price of its DL-methionine 99% feed grade product, branded as MetAMINO, by 7%.
