Multiple sources, including UN and UNCTAD officials, state that about one-third of global fertilizer trade passes through the Strait of Hormuz, and this was true as of 2026-10-24. Other sources give somewhat lower figures (about 30%, or 20-30%), and the claim says 'supply' where the sources mostly say 'trade', but these differences are within rounding of 'approximately one-third'.

This claim is about the present, so it is judged as of the day it was checked.

What was said

… It makes sense for soft power. Then Linda McMahon canceled the farm-to-cafeteria program. Then Trump's tariff pushed China away, our largest purchaser of soybeans. Then all of your farm machinery runs on diesel, and finally, a third of the fertilizer in the world goes through the Strait of Hormuz.

What we found

Supports. A UN task force head states that one-third of all fertilizers in the world go through the Strait of Hormuz, and UN News reports one-third of global fertilizer trade passes through the corridor in normal times.[2]

Supports. UNCTAD data cited in a Yahoo article and by Weathernews state that about one-third of world fertilizer shipments, or of global seaborne fertilizer trade, normally pass through the strait.[3][4]

Supports. The Globe and Mail reports that approximately one-third of the world's fertilizer passes through the Middle East trade corridor, citing the Strait of Hormuz bottleneck.[5]

Context. Reuters cites about 30% of traded fertiliser passing through the strait, and FAO states up to 30% of internationally traded fertilizers normally transit it, a figure close to one-third.[1][6]

Context. Some estimates are lower, such as a 20-30% range for fertilizer exports in an IEEE-linked analysis, so the precise share depends on the measure and dataset used.[7]
