What This Indicator Measures
Weekly FOB China assessment of compacted ammonium sulphate in USD/mt.
Ammonium Sulphate: A physical price for ammonium sulphate, a nitrogen-and-sulphur fertilizer (about 21% N and 24% S). Standard, granular and compacted grades are separate markets.
Specification · stated by the source for this series
- Compacted grade, from the series name.
- Approximately 21% nitrogen and 24% sulphur by mass.
- Grade (standard/compacted/granular) is part of the series definition.
Basis: FOB China
- FOB (free on board): the price covers the product loaded on the vessel at the named origin; sea freight and insurance to the destination are excluded, so FOB values from different loading areas are not delivered-cost equivalents.
- China is a Pacific exporter of urea and ammonium sulphate; FOB China values refer to loadings at Chinese ports and are subject to Chinese export policy.
Unit: USD/mt
- Most series are USD per metric tonne of product, not per tonne of nitrogen. NOLA barge series are USD per short ton (907.18 kg); Rouen and German inland series are EUR/mt.
- FOB origin and CFR destination values differ by freight and insurance and are not interchangeable.
