Sum of all reported bilateral flows of the product in the year, in tonnes of product, after FertRadar adjustments (phantom tonnes imputed, reclassifications, duplicate codes removed).
Value
Declared value of the flows, FOB equivalent (freight and insurance excluded), in US dollars.
Unit value
Value divided by quantity over flows with a quantity. A customs average across contracts and grades, not a market price.

2025 is a FertRadar estimate from the monthly customs declarations (UN Comtrade), hatched in the charts. Replaced by the annual data when published.
Values exclude freight and insurance (FOB equivalent). Unit values are customs averages over shipments under different contracts, not market prices.
Publication rules: routes shown when above 1% of the total or 10,000 t (the rest under "others"); unit values only for at least 1,000 t; year-on-year changes only when both years are at least 1,000 t; supplier concentration only for importers of at least 50,000 t.
