Fonterra remains at No 6 among the dairy company powerhouses of the world with a French company tightening its No 1 spot.
The privately held Lactalis was found in Rabobank's latest Global Dairy Top 20 report to have strengthened its position.
Lactalis' turnover rose to $US26.7 billion ($NZ43 billion) last year - an increase of $US4.7 billion or 16.2 per cent on the previous year and it now sits well clear of Switzerland's Nestle, generating $US21.3 billion.
Fonterra was sixth on the list for the third year in a row with 2021 sales of $US14.8 billion, up by $US1.2 billion.
Rabobank senior agri analyst Emma Higgins said Lactalis' double-digit percentage sales growth was driven by it buying the KraftHeinz's US natural cheese business and Groupe Bel's Royal Bel Leerdammer, Bel Italia, Bel Deutschland and Bel Shostka Ukraine.
