In week 45 of 2026 (October 30 to November 5), 37 surveyed Chinese amino acid plants produced 81,600 tonnes, down 5,000 tonnes week on week, with utilization at 63%, down 3 points. Lysine output fell to 55,800 tonnes with utilization at 56%, while corn processing held flat at 184,800 tonnes.
Lower amino acid output reduces demand for corn as feedstock and tightens lysine supply, which is mildly supportive for lysine prices.
