Tanzania’s Black Pepper Numbers Don’t Agree With Each Other. Here’s Why That’s the Honest Story.

Tanzania’s own spice-industry association put it plainly to The Citizen in 2019: “We are scattered; every spice farmer survives on his/her own, which makes it very difficult to collect data.” Seven years on, that sentence is still the most honest starting point for Tanzania’s black pepper numbers — because almost none of the figures in circulation agree with each other.

Two production estimates, two different years, no reconciliation

One aggregator reproducing FAOSTAT data puts Tanzanian black pepper production at 457 tonnes in 2022. A different aggregator cites 437 tonnes for “2024” without a traceable original source. These are close enough to be describing the same underlying (small) industry, and far enough apart, with different attributed years, that treating either as a precise national total would be false confidence. No Tanzania Revenue Authority, Bank of Tanzania, or Ministry of Agriculture black-pepper-specific series exists to adjudicate between them.

Export figures that don’t sum to a clean trend

Tridge’s trade-intelligence data shows Tanzanian black pepper exports falling from 279.94 tonnes ($1,004,611) in 2022 to 254.56 tonnes ($803,546) in 2023 — a real year-on-year decline, with no source found explaining it. A separate, commonly-cited “2024” figure of 738 tonnes and $2.38 million in export value could not be independently confirmed in this review: the page it traces to (OEC) returned only a title when fetched directly, not the underlying trade table. We are not publishing that figure here, even though it is the one that shows up most often in search results — an unverifiable number does not become verifiable by being repeated.

Two different kinds of “price,” easily confused

A 2016 wholesale figure of TZS 22,000/kg, sourced to TASPA via allAfrica, is the oldest data point this platform holds for Tanzanian black pepper. A newer figure — roughly $3.23/kg as of January 2024 — is not a comparable domestic price: it is an export unit value, computed by dividing UN Comtrade’s export value by export volume. The two numbers measure different things eight years apart, on different sides of the farm gate, and should never be presented as a single trend line.

What is actually solid

Underneath the disputed macro numbers, two real businesses have independently-corroborated black pepper activity: Trianon Spices, whose Muheza (Tanga Region) factory location and black pepper product line are confirmed both by the company’s own site and by Dutch development-finance institution Invest International; and Horizon Group Africa, whose Tanzania black pepper handling is confirmed by two independent 2025 trade-press reports of a $5 million Aavishkaar Capital/KfW financing deal. A 2026 peer-reviewed agricultural survey independently places the crop’s real, if smallholder-scale, growing footprint in Morogoro Rural (Uluguru Mountains) and Muheza (East Usambara Mountains) — which is also, notably, where Trianon’s own factory sits. That convergence, from two unrelated types of source, is more trustworthy than any single trade-value figure in this piece.
