What This Indicator Measures
Daily FOB China assessment of standard caprolactam 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
- Standard caprolactam, explicitly stated in the daily price table of Argus Nitrogen, 3 September 2026.
- 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.

Computed Summary
Statements below are calculated by CommodityScope from the loaded history only. Each one names its period and method; none explains why a value moved.
The latest assessment of $192.00/mt on 3 Sep 2026 is up $12.00 (+6.7%) from the previous daily assessment (20 Aug 2026).
Method: Computed by CommodityScope as the difference between the two most recent loaded daily observations (14 calendar days apart).
The source edition itself printed a day change of 0.00, which is kept separately from the computed figure above.
Method: Published change copied from the edition; it may reference an assessment date that is not loaded here.
Over the loaded history (19 Mar 2026 – 3 Sep 2026), the highest assessment was $295.00/mt on 7 May 2026 and the lowest was $180.00/mt on 20 Aug 2026.
Method: Minimum and maximum of the published midpoint over the loaded history (19 Mar 2026 – 3 Sep 2026, 17 observations). This is not an all-time record.
- No completed calendar month with at least 8 daily observations is loaded, so the latest value is not compared with a monthly average.
Price Changes and Historical Range
Published changes are copied from the source edition. Computed changes are CommodityScope calculations between loaded daily observations; the two are shown separately and may differ when an intermediate edition is not loaded.
