The figure from the customs system
Four of thirty-nine: UNCTAD, the Rwanda Trade Portal, Saint Lucia and the United Kingdom.
Where customs administrations and trade portals already publish an import duty calculator, where each figure comes from, and what each one includes. Every cell marked yes was seen on the page linked, on 22 September 2026; what could not be seen is marked with a question mark, not with a no. The UNCTAD row is the calculator described on the main page.
Thirty-nine calculators, one row each. Hover a cell to read the evidence behind it. The first row is the UNCTAD calculator; the rest are sorted by where their figure comes from.
