TSP price (World Bank benchmark)

TSP

TSP (triple superphosphate), spot, import US Gulf. Monthly average of the World Bank benchmark, as published.

Customs unit value

Customs unit value: world average of declared values per tonne (FOB equivalent), annual. Not a market price and not comparable month by month with the benchmark; as an average of contract prices it lags the benchmark in fast-moving markets.

Monthly customs unit value

World customs unit value: declared value per tonne of all import routes of at least 1,000 t in the month (cost, insurance and freight included), outliers excluded. An average of contract prices: it follows the benchmark with a lag and includes freight.

• Benchmarks differ in location and delivery terms; a customs unit value is an annual average of declared values, not a market price.
• Customs unit values average the contract prices of a whole year, so they lag spot benchmarks when markets move fast (2008-2009, 2021-2023).
