DL-Methionine / HMTBa (Feed-Grade)

Global animal nutrition subsidiary of China National BlueStar Group; world's second-largest methionine producer (~25% global share). Operates Nanjing plant (~350,000 MT/yr DL-Met + 180,000 MT/yr liquid methionine). Key products: Rhodimet NP99, Smartamine, Rhodimet AT88.

Evonik Industries AG (XETRA: EVK; Essen Germany; MDAX listed); world's largest DL-methionine producer under the MetAMINO brand. Total DL-methionine capacity exceeds 700,000 MT/year across three continental hubs: Jurong Island Singapore (~340,000 MT/year — world's largest single methionine complex, expanded +40k MT August 2024), Theodore Mobile County Alabama USA (~245,000 MT/year), and Antwerp Belgium (~120,000 MT/year). The Wesseling Germany DL-Met line closed Q1 2021 as Evonik consolidated production to the three-hub network. Evonik first commercialized DL-methionine synthesis in the 1950s under predecessor Degussa. MetAMINO is Evonik's largest single product. ~30-32% global market share. In February 2022 Evonik announced a $176.5M investment in a new methyl mercaptan (MMP intermediate feedstock) plant at the Alabama site.

Sumitomo Chemical Co. Ltd. (Tokyo Japan; TYO: 4005; Sumitomo Group); #3 global DL-methionine producer at ~13% market share via Niihama Ehime Works (Ehime Prefecture Shikoku Japan). After a major expansion completed October 2018 (+100,000 MT/year new line), the Niihama facility reached ~250,000 MT/year — one of the world's largest single methionine plants. Also produces crop protection chemicals (agrichemicals), petrochemicals, and pharmaceuticals. The MetiPEARL / liquid methionine brand competes directly with Evonik MetAMINO and Adisseo Rhodimet in Asian poultry markets. Japan is the only significant Japanese methionine production base globally.

Novus International (Chesterfield / St. Charles MO USA; owned 80% Mitsui & Co. Japan + 20% Nippon Soda Japan); global animal nutrition company producing ALIMET (HMTBa — 2-hydroxy-4-(methylthio)butanoic acid), a liquid methionine hydroxy analog that is approved as bioequivalent to DL-methionine in poultry and swine diets. ALIMET plant at Chocolate Bayou TX near Alvin Brazoria County (~284,000 MT/year nameplate capacity; first shipment 1984). Also produces MFP (Methionine Feed Grade Powder) and gut health products. ~10-15% global methionine market share. Note: ALIMET is an analog (not identical to dry DL-methionine) — approved by FDA and EU for equivalent nutritional use in poultry. US-based production is Japanese-owned, not American-owned. Revenue ~$650M/year.

Chinese specialty chemicals company (Shenzhen-listed); the most significant new entrant in the global methionine market. Started commercial production of a 150,000 MT/year DL-methionine line in October 2023 (after delaying from the planned June 2023 start due to the 2023 methionine price crash). NHU's entry was a key catalyst for the 2023 global methionine oversupply event that cut prices roughly in half from COVID-era peaks. Also produces vitamins (Vitamin E, Vitamin A) — the company is a major factor in multiple feed additive markets simultaneously.

CJ CheilJedang Corporation (Seoul South Korea; KRX: 097950; subsidiary of CJ Group); South Korean food and bio conglomerate; world's largest L-lysine producer (~25% global share) via fermentation biotechnology. Operates the world's first and only commercial-scale bio-based L-methionine facility at Kertih Biopolymer Park Terengganu Malaysia (80,000 MT/year; opened 2015 using genetically engineered E. coli K-12 fermenting plant sugars — producing L-methionine rather than racemic DL-methionine). CJ's fermentation-route L-methionine is chemically distinct from synthetic DL-methionine but is approved as nutritionally equivalent in poultry diets. Also produces tryptophan, threonine, and other feed amino acids globally. Pet food market interest in fermentation-derived (non-petrochemical) amino acids is growing.
