Nigeria & Sierra Leone Trade Brief 2026

A micro corridor, an order of magnitude smaller than Nigeria's other West African trade relationships — mapping the 2023 fertiliser spike, the persistent animal-fats import anchor, and the mid-period trade balance flip.

Executive summary

A micro corridor, an order of magnitude smaller than Nigeria's other West African trade relationships.

Nigeria–Sierra Leone bilateral trade is minute relative to Nigeria's global trade — well under 0.01% of Nigeria's total exports in every year of 2021–2024 — and it does not follow a single-commodity pattern. Nigerian exports to Sierra Leone moved from $2.4m (2021) to $1.6m (2022), then jumped 243.8% to $5.5m (2023), before falling back 45.5% to $3.0m (2024). Unlike Nigeria's larger regional corridors, no single product dominates: the export basket is a diversified mix of manufactured and consumer goods — glass & glassware, pharmaceuticals, cereal preparations, electrical machinery — with no HS chapter exceeding 30% of the total in any year except 2023.

The 2023 export spike has a single, identifiable cause: a one-year Fertilizer shipment. Fertilizers (Ch. 31) do not appear in Sierra Leone's top-10 ranked imports from Nigeria in 2021, 2022, or 2024, but contributed $4.2m in 2023 — 76% of that year's $5.5m export total. Strip that single line out and 2023 exports would have been roughly $1.3m, in line with the corridor's other years. This is the same pattern of a single-year, single-product anomaly seen in Nigeria's larger corridors (e.g., the 2023 Mineral Fuels spike to Senegal), but at a scale two orders of magnitude smaller, and it plausibly tracks the same March 2022 opening of Nigeria's Dangote Fertilizer plant (3 million tonnes/year urea capacity) that reshaped several of Nigeria's regional fertiliser export lines that year.

A single persistent, but shrinking, import anchor. Animal or vegetable fats, oils & waxes (Ch. 15) is Sierra Leone's largest export to Nigeria in every year of the dataset — the corridor's only true anchor product on either side of the ledger — but it more than halved from $5.1m (2021) to $0.88m (2023), before partially recovering to $1.8m (2024). Organic Chemicals (Ch. 29) is the only other line to clear $200,000 in any year, appearing in 2022 ($299,603) and 2024 ($246,175) but absent from the 2021 and 2023 top-10 rankings entirely — an intermittent presence the trade data alone cannot explain.

The trade balance flips sign mid-period. Nigeria ran a bilateral deficit with Sierra Leone in 2021 (–$2.9m) and 2022 (–$1.0m), driven by the animal-fats import line outweighing Nigeria's smaller and more diversified export basket, then flipped to a surplus in 2023 (+$4.4m, inflated by the fertiliser spike) and 2024 (+$0.9m). At this scale, the swings are consistent with a handful of individual shipments moving the entire corridor total, rather than a structural shift in trade capacity on either side.

Sierra Leone is a small, disinflating, post-coup-attempt ECOWAS partner. With nominal GDP of roughly $7.5–8.4bn (2024–2025) and real GDP growth that slowed to 3.9% in 2024 from 5.7% in 2023 (projected to recover to 4.4% in 2025 and 4.8% in 2026), Sierra Leone is recovering from a severe 2022–2023 inflation shock — CPI fell from 47.7% (2023) to roughly 30% (2024) and into single digits by late 2025. The country is still working through the aftermath of a failed 26 November 2023 coup attempt on Freetown's main barracks and prisons, and President Julius Maada Bio's disputed June 2023 re-election, even as Bio completed a one-year term as ECOWAS Authority chairman in July 2026. Like Senegal, Sierra Leone is a full ECOWAS and AfCFTA member, so the ECOWAS Trade Liberalisation Scheme applies directly to this corridor — the binding constraint on its growth is scale and logistics, not tariff access.

Key findings

1. Nigeria-Sierra Leone bilateral trade is consistently minute, representing less than 0.01% of Nigeria's total exports annually.

   Bilateral trade between Nigeria and Sierra Leone remains minuscule, never exceeding 0.01% of Nigeria's total global exports between 2021 and 2024, indicating a very limited economic relationship on a macroeconomic scale.

2. Nigerian exports to Sierra Leone are diversified, with a significant spike in 2023 due to a one-off fertilizer shipment.

   Nigeria's export basket to Sierra Leone is a mix of manufactured and consumer goods, but a $4.2 million fertilizer shipment in 2023 accounted for 76% of that year's exports, a single anomaly not seen in other years.

3. Sierra Leone's exports to Nigeria are anchored by Animal or Vegetable Fats, Oils & Waxes, though this trade has declined significantly.

   Animal or Vegetable Fats, Oils & Waxes (Ch. 15) consistently formed Sierra Leone's largest export to Nigeria, but its value plummeted by 82.7% from $5.1 million in 2021 to $0.88 million in 2023, recovering partially to $1.8 million in 2024.

4. The trade balance between the two nations flipped from a Nigerian deficit to a surplus mid-period.

   Nigeria's bilateral trade balance with Sierra Leone shifted from a deficit of -$2.9 million in 2021 and -$1.0 million in 2022 to a surplus of +$4.4 million in 2023 (due to the fertilizer spike) and +$0.9 million in 2024.

5. Market size, logistics, and underlying economic scale are the primary constraints to corridor growth, not tariff barriers.

   Despite both countries being ECOWAS and AfCFTA members, suggesting tariff-free trade, the corridor's growth is limited by the small market size, high logistics costs, and the modest scale of both economies' tradeable goods sectors.

6. Sierra Leone is experiencing sharp disinflation and economic recovery amidst political instability.

   Sierra Leone's CPI fell dramatically from 47.7% in 2023 to roughly 30% in 2024, projected to reach single digits by late 2025, even as the country navigates the aftermath of a failed November 2023 coup attempt and disputed 2023 elections.

7. Key data anomalies, such as the 2023 fertilizer export and the decline in animal-fats imports, require further verification.

   To understand the corridor's true potential, further investigation is needed to confirm if the 2023 fertilizer shipment represents a repeatable commercial development and if the decline in Sierra Leone's animal-fats exports signifies a genuine supply-side issue or market diversion.

BILATERAL TRADE SNAPSHOT

Nigeria's exports to Sierra Leone have never exceeded $5.5m in any year of the 2021–2024 period, and imports from Sierra Leone have never exceeded $5.3m — a corridor roughly 100–300 times smaller than Nigeria's trade with Senegal over the same years. Both flows moved in different directions across the period: exports troughed in 2022 ($1.6m) and peaked in 2023 ($5.5m) on the back of the one-off fertiliser shipment, while imports declined almost continuously from $5.3m (2021) to $1.1m (2023) before a partial rebound to $2.1m (2024).

The trade balance swung from a Nigerian deficit in 2021–2022 to a Nigerian surplus in 2023–2024, tracking the decline in Sierra Leone's animal-fats exports and the one-year fertiliser spike almost exactly. At no point does the bilateral balance exceed $5m in magnitude — a scale at which a single shipment or reporting adjustment can flip the sign of the entire corridor, which counsels caution in reading any one year's balance as a trend.

Set against Nigeria's global trade — exports ranging $58.1bn–$71.6bn and imports $48.1bn–$67.4bn across the same four years — the Sierra Leone corridor represents between 0.002% and 0.009% of Nigeria's total export book in any given year. This is not a corridor where bilateral trade policy is likely to move Nigeria's aggregate trade figures; its relevance is regional and developmental rather than macroeconomic.

EXPORT PROFILE

Unlike Nigeria's larger West African corridors, no single product dominates Nigeria's exports to Sierra Leone in a persistent way. The most consistent lines — Glass & Glassware (Ch. 70), Pharmaceutical Products (Ch. 30), and Preparations of Cereals, Flour, Starch or Milk (Ch. 19) — appear in all four years but each stays within a narrow $29,000–$347,000 band, never approaching half of any year's total. The one exception is 2023, when a single, non-recurring Fertilizers (Ch. 31) line worth $4.2m accounted for 76% of that year's $5.5m export total — without it, 2023 exports would sit at roughly $1.3m, below both 2021 and every other year. Electrical Machinery (Ch. 85) and Beverages, Spirits & Vinegar (Ch. 22) are the next most persistent lines, each present in three of the four years, while Cars, Tractors, Trucks & Parts (Ch. 87) and Used Clothes & Textile Articles (Ch. 63) appear only in 2021–2022. Cocoa & Cocoa Preparations (Ch. 18) resurfaced strongly in 2024 at $1.4m — its highest level in the dataset — after two years of decline (from $102,015 in 2021 to $30,137 in 2022 and absent from the 2023 top 10 entirely), a swing large enough to be the second story of the export side after the 2023 fertiliser spike.

IMPORT PROFILE

Sierra Leone's exports to Nigeria are anchored, in every single year, by Animal or Vegetable Fats, Oils & Waxes (Ch. 15) — the only product in either direction of this corridor that is both persistent and consistently the largest line. But its trajectory is one of steady erosion: $5.1m (2021) → $2.2m (2022) → $0.88m (2023), an 82.7% cumulative decline over three years, before a partial rebound to $1.8m in 2024 that still leaves it 65% below its 2021 level.

Relationship at a Glance

Micro-scale, diversified corridor — no single-commodity dominance on either side; Nigeria exports a mixed basket of manufactured/consumer goods, Sierra Leone exports a shrinking animal-fats line plus a thin manufacturing tail

Asymmetry Analysis

Nigeria's exports to Sierra Leone are a diversified basket of manufactured and processed goods — glass, pharmaceuticals, cereal preparations, electrical machinery — reflecting Nigeria's larger manufacturing and processing base rather than any single natural-resource endowment. Sierra Leone's return flow is smaller in most years and anchored by a single primary/processed commodity, Animal or Vegetable Fats, Oils & Waxes, which does not correspond to Sierra Leone's own best-known global export commodities (iron ore, rutile, diamonds, cocoa). As with Nigeria's other West African partners, Sierra Leone's headline mineral exports (iron ore in particular, the mainstay of its export economy since 2011) do not show up at scale in the bilateral data with Nigeria, reflecting a demand mismatch rather than a supply constraint: Nigeria is not a natural buyer of Sierra Leonean iron ore, which is destined overwhelmingly for international steel markets

Trade Potential Gap

Two structured opportunities stand out, both modest in absolute scale but large in relative terms for a corridor this small. First, Nigeria's diversified manufactured-goods export basket — pharmaceuticals, cereal preparations, glass, electrical machinery — could scale meaningfully if Sierra Leone's own consumer market continues to recover alongside disinflation (CPI falling from 47.7% in 2023 toward single digits by late 2025) and GDP growth normalises toward the 4.4–4.8% range projected for 2025–2026. Second, resolving the corridor's two data anomalies — confirming whether the 2023 Fertilizer shipment reflects a genuine, repeatable buyer relationship (plausibly tied to Nigeria's Dangote Fertilizer plant, opened March 2022) and whether Sierra Leone's declining animal-fats exports reflect a supply-side contraction or diversion to other markets — would clarify whether either side of this corridor has real headroom to grow beyond its current $1–$5m range.

AfCFTA and ECOWAS Framework

Sierra Leone, like Senegal, is a founding-era ECOWAS member state and has ratified the AfCFTA agreement, meaning the ECOWAS Trade Liberalisation Scheme (ETLS) already applies directly to this corridor without the cross-bloc complications that would arise with a non-ECOWAS partner. That the corridor nonetheless remains two to three orders of magnitude smaller than Nigeria's trade with Senegal — despite operating under the same tariff and rules-of-origin framework — strongly suggests that market size, logistics cost, and the underlying scale of both economies' tradeable-goods sectors, rather than any tariff or regulatory barrier, are the binding constraints on this relationship's growth.

Sierra Leone: A Fragile Post-Coup-Attempt Recovery

Sierra Leone's most consequential recent security event was the failed coup attempt of 26 November 2023, when gunmen — reportedly linked to a former president's bodyguard detail — attacked Freetown's main Wilberforce military barracks and the Pademba Road Prison complex, freeing nearly 2,000 inmates before being repelled by government forces. At least 14 soldiers, one police officer and one prison guard were killed, with three attackers also reported dead. The attack came five months after President Julius Maada Bio's disputed re-election in June 2023, a vote that the United States, United Kingdom, Ireland, Germany and France jointly criticised for a lack of transparency in the tabulation process, and which the European Union's Election Observer Mission described as opaque, citing statistical inconsistencies. In the aftermath, dozens of soldiers were charged with mutiny, treason and murder, with convictions and sentencing — including a 182-year sentence handed to a former presidential bodyguard — continuing well into 2025.

Sierra Leone: A Sharp Disinflation Alongside Slowing Growth

Sierra Leone's real GDP growth slowed to 3.9% in 2024 from 5.7% in 2023, with the African Development Bank attributing the deceleration mainly to persistent inflationary pressure; growth was driven by services, mining and agriculture on the supply side and by private consumption and investment on the demand side. The African Development Bank projects growth accelerating again to 4.4% in 2025 and 4.8% in 2026, driven by continued expansion in mining, agriculture and services. Nominal GDP stood at roughly $7.5–$8.4bn across 2024–2025 estimates, making Sierra Leone one of the smallest economies among Nigeria's ECOWAS partners.

On the Trajectory (2025-2027 Outlook)

The base-case scenario for 2025–2027 is a corridor that continues to oscillate in the $2–$4m range for Nigerian exports to Sierra Leone, without the 2023 fertiliser shipment repeating, alongside a gradual, partial recovery in Sierra Leone's animal-fats exports as its own agricultural and processing sector stabilises with disinflation. This assumes the 2023 spike was genuinely a one-off transaction; if instead it reflects the start of a repeat buyer relationship tied to Nigeria's Dangote Fertilizer plant's regional distribution strategy, a return to $4–$5m-plus export years within the outlook window is plausible but cannot be confirmed from the Trade Explorer data alone.

For the Reader's Action

For a trade ministry or policy body, this corridor's small scale means the priority is less about tariff negotiation — ETLS and AfCFTA already apply — and more about verifying whether the 2023 Fertilizer shipment and the multi-year decline in Sierra Leone's animal-fats exports reflect genuine commercial developments or reporting artefacts, since both currently rest on Trade Explorer aggregates alone. Given the corridor's immateriality to Nigeria's aggregate trade figures, this is better treated as a developmental and diplomatic relationship-building exercise than a trade-policy priority.

Frequently asked questions

What is the overall scale of trade between Nigeria and Sierra Leone?

Bilateral trade between Nigeria and Sierra Leone is minute, typically representing well under 0.01% of Nigeria's total global exports annually. Nigerian exports have never exceeded $5.5 million and imports from Sierra Leone never exceeded $5.3 million in the 2021-2024 period, making it 100–300 times smaller than Nigeria's trade with Senegal.

What products does Nigeria primarily export to Sierra Leone?

Nigeria's exports to Sierra Leone consist of a diversified mix of manufactured and consumer goods, including glass & glassware, pharmaceuticals, cereal preparations, and electrical machinery. There was a significant, one-off spike in 2023 due to a $4.2 million fertilizer shipment, which accounted for 76% of exports that year.

What products does Sierra Leone primarily export to Nigeria?

Sierra Leone's exports to Nigeria are primarily anchored by Animal or Vegetable Fats, Oils & Waxes (Ch. 15), which has been the largest and most persistent line. However, the value of these exports declined by 82.7% from $5.1 million in 2021 to $0.88 million in 2023, with a partial recovery to $1.8 million in 2024.

What is the current trade balance between Nigeria and Sierra Leone?

The trade balance flipped during the 2021-2024 period. Nigeria initially ran a deficit of –$2.9 million in 2021 and –$1.0 million in 2022, but then shifted to a surplus of +$4.4 million in 2023 (inflated by the fertilizer spike) and +$0.9 million in 2024.

What are the main factors limiting trade growth between Nigeria and Sierra Leone?

Despite both countries being ECOWAS and AfCFTA members with applicable trade liberalization schemes, the primary constraints on trade growth are market size, logistics costs (due to no shared land border), and the underlying scale of both economies' tradeable-goods sectors, rather than tariff or regulatory barriers.
