Weekly price assessments and deal reports from the Argus nitrogen and phosphate market. Every report carries the date it was written, so you always know which week the numbers belong to.
Ammonium sulfate week 43, 2026: the allocation arrived, the tonnage did not
A week of allocation news and no tonnage. The second round landed at 1.3-1.7mn t, the split is unpublished, Brazil is covered into December and a 42pc nutrient premium caps how far this can run.
Read the report →Ammonium sulfate, 29 October 2026: the second allocation finally has a tonnage, and the compactor share is the number that decides Brazil
A number appeared this week where last week there was only a rumour: 1.3-1.7mn t, about a third of the first round. But the headline tonnage is not the tradeable number. The split is — and if compactors get 40pc, Brazil is the market that feels it first.
Read the report →Ammonium sulfate, 28 October 2026: the second allocation is out and the offers have not moved

Read the report →China shipped 2.85 million tonnes of ammonium sulfate in September 2026. The volume is the story
Nine months of Chinese ammonium sulfate exports grew 6.9%. September alone grew 26.4%. Everything that happened this year happened in the last four weeks of the period.
Read the report →Ammonium Sulfate, 23 October 2026: China FOB $215-220 on Offers, Not on Deals
Fob China moved up to $215-220/t and the domestic price stopped falling. The unusual part is that almost nothing traded at the new level, which tells you what kind of market this is.

Europe is now China's best ammonium sulfate outlet
Standard caprolactam-grade has sat at $210-215/t fob for three weeks, and that flatness is being read as firmness. Underneath it, the domestic price slipped below the export price and compacted material eased. A frozen quote on an empty offer stack is a pause, not a floor.
