Tunisia's decisive endowment is not under the ground but on the factory floor. Automotive wiring harnesses and insulated wire (HS8544) are the country's single largest export line, at USD 2.99 billion in 2023, or 14.9% of all merchandise exports, up from USD 2.37 billion in 2022 (TrendEconomy/UN Comtrade); OEC records USD 3.23 billion for 2023 and ranks Tunisia the 13th-largest global exporter of insulated wire, with Germany, France and Italy the leading destinations. Production is anchored by Leoni, Yazaki, Sumitomo, Dräxlmaier and other harness makers serving European automakers. Around this sits a wider electrical cluster: HS85 as a whole reached USD 5.39 billion in 2023, some 26% of exports, with switching and protection apparatus (HS8536) a top line and boards (HS8537) produced for European industrial customers. Aerospace adds a second precision layer — the El Mghira aeropark near Tunis spans 200,000 square metres, hosts more than ten firms including Airbus Atlantic, Corse Composites, Figeac Aero, Mecahers, Latécoère and Safran, employs over 3,000 people and produces roughly 2.5 million parts a year (DG Trésor France, 2024). Textiles and apparel form a long-established EU nearshoring base of about 1,000 firms and some 160,000 workers, with combined knit and non-knit clothing exports of roughly USD 3.6 billion in 2024.
The mineral identity is phosphate. The Gafsa basin holds over 800 million tonnes of active reserves, the undeveloped Sra Ouertane deposit in the north is estimated at around 5 billion tonnes (Knowledge Ridge/CPG, 2022), and the USGS lists Tunisia's phosphate rock reserves at 2.5 billion tonnes — the fourth largest in the world (USGS MCS 2026). Groupe Chimique Tunisien transforms Tunisian rock into phosphoric acid, DAP, TSP, MAP and DCP across Gabès, Skhira, Sfax and M'dhilla, with installed capacity of 8.5 million tonnes of rock and 1.6 million tonnes of P2O5 a year. In agriculture, olive oil is the crown: output rebounded to 340,000 tonnes in 2024/25, a rise of 55%, and Tunisia ranked second worldwide in exports after Spain and ahead of Italy, capturing 27.9% of global olive oil exports with 226,472 tonnes, an increase of 23.3% over 2023/24 (IOC via News Tunisia). The olive sector spans approximately 1.7 million hectares, around 35% of cultivable land, supporting more than 300,000 producers. Tunisia is also the world's leading date exporter by value, led by the premium Deglet Nour variety, with roughly USD 256.7 million exported in 2023 and about 21% of world date export value.
Underpinning all of this is human capital. Per FIPA-Tunisia, the country has more than 260 university establishments and 1,000 professional training centres, produces more than 65,000 graduates annually, more than 30% of them in scientific and engineering fields, and is supported by a network of 47 engineering schools. Tunisia ranks 47th globally in the Harvard Growth Lab's Economic Complexity Index on 2024 data, having improved twelve positions over the prior decade — among the highest complexity ranks in Africa, typically first or second on the continent alongside South Africa. Harvard assesses Tunisia as more complex than expected for its income level. The strategic implication is stated plainly in the audit: Tunisia already possesses the diversified productive know-how, in electricals, light machinery, chemicals and precision assembly, that most African economies lack. Its constraint is scale, capital and market orientation, not capability.
The endowment in depth
Tunisia's mineral identity is phosphate. The Gafsa basin holds over 800 million tonnes of active reserves, while the undeveloped Sra Ouertane deposit in the north is estimated at around 5 billion tonnes; USGS lists national phosphate rock reserves at 2.5 billion tonnes, the fourth largest in the world (USGS MCS 2026). The production trajectory, not the geology, is the central story. Tunisia produced roughly 7.6 million tonnes of marketable rock in 2010 on USGS figures (8.13 Mt on official Tunisian crude/commercial figures) before the 2011 revolution triggered a collapse to about 2.28 Mt. Output has since plateaued in a 2.6-4.1 Mt band, recorded at 3.28 Mt in 2024 (MCS 2026), with CPG director-general Abdelkader Amidi confirming company output of 3.04 Mt in 2024 rising to 3.9 Mt in 2025. The national plan targets 14 Mt by 2030, a projection requiring more than a tripling of current output. Beyond phosphate, Tunisia produces lead and zinc from small deposits (Bou Jaber, Fej Lehdoum, Sidi Idris, where combined capacity targets of about 120,000 t/yr lead and 70,000 t/yr zinc were never fully realised), iron ore (production up 54% in 2021), gypsum, and Mediterranean solar-evaporation sea salt at over one million tonnes a year.
On energy, Tunisia is a modest and declining hydrocarbon producer that has been a net importer since around 2000. Crude output was about 29,200 barrels per day at end-September 2024, down from a 1980 peak of 118,000 b/d, anchored on the El Borma field (discovered 1964) alongside Ashtart, Miskar, Hasdrubal and the Nawara field, which came online in 2020 and supplied about 23% of domestic gas in 2024. Gas production has roughly halved since 2010 to 1.8 bcm in 2024. Installed power capacity is 5,944 MW across 25 plants producing 19,395 GWh in 2024, with state utility STEG controlling 92.1% of capacity; roughly 93.7% of electricity comes from fossil fuels, and Tunisia imports 62% of the gas used for power via the TransMed pipeline from Algeria. Energy self-sufficiency fell from 47% in 2023 to 45% in 2024 to 39% in 2025. Renewables stood at about 787 MW as of June 2025 (485 MW solar, 240 MW wind, 62 MW hydro) against a government target of 35% renewables and 4,850 MW by 2030.
Agriculture is smaller than industry but strategically vital, crowned by olive oil. Output swings with the alternate-bearing cycle, rebounding to 340,000 tonnes in 2024/25 (+55%) and reaching a record 500,000 tonnes in 2025/26, nearly 80% of it organic, making Tunisia the world's second-largest producer behind Spain. In 2024/25 Tunisia was the world's second exporter after Spain, capturing 27.9% of global olive oil exports with 226,472 tonnes; a structural weakness is that 80-91% of exports leave in bulk, with value-added bottling under 9%. Tunisia is also the world's leading date exporter by value, led by the premium Deglet Nour variety, shipping roughly USD 256.7 million (129,929 tonnes) in 2023 and capturing about 21% of world date export value. The olive sector spans approximately 1.7 million hectares, around 35% of cultivable land, supports more than 300,000 producers, and up to 10% of the population depends on it. The existing industrial base is the decisive endowment. Automotive wiring harnesses and insulated wire (HS8544) are the single largest export at USD 2.99-3.23 billion in 2023, making Tunisia the 13th-largest global exporter, anchored by Leoni, Yazaki, Sumitomo and Dräxlmaier. The El Mghira aeropark near Tunis (200,000 m2, 10-plus firms, over 3,000 employees, some 2.5 million parts a year) hosts Airbus Atlantic, Corse Composites, Figeac Aero, Latécoère and four Safran sites. Electrical machinery (HS85) totalled USD 5.39 billion in 2023, textiles and apparel span roughly 1,000 firms and 160,000 workers with combined clothing exports near USD 3.6 billion in 2024, and Groupe Chimique Tunisien transforms rock across Gabès, Skhira, Sfax and M'dhilla with installed capacity of 8.5 Mt rock and 1.6 Mt P2O5 a year, though running at only about 40% utilisation in 2025. Over 40 pharmaceutical plants cover around 80% of market needs by volume and 60% by value.
The human-capital base underwrites this industrial density. Tunisia has more than 260 university establishments and 1,000 professional training centres, produces over 65,000 graduates annually with more than 30% in scientific and engineering fields, operates a network of 47 engineering schools, and ranks first in Africa for graduates in scientific and engineering fields, supported by the CEMIA centre of excellence (600 trainees a year) and 15 sectoral training centres. French companies employ roughly 70% of aerospace workers, reflecting deep francophone technical ties, and the offshore "totalement exportatrice" regime supplies a disciplined, cost-competitive engineering and assembly workforce. On logistics, Radès is the main container port with El Mghira about 10 km away, served alongside Enfidha-Hammamet and Tunis-Carthage airports; 98% of foreign trade by value moves by sea, and EU proximity underpins the nearshoring model. The binding physical weakness is the Gafsa-Sfax/Gabès phosphate rail corridor, whose ageing wagon fleet is repeatedly cited by CPG as a production constraint.
Economic complexity & comparative advantage
Tunisia ranks 47th globally in the Harvard Growth Lab's Economic Complexity Index (2024 data), an improvement of 12 positions over the prior decade and among the highest ECI ranks in Africa, typically first or second on the continent alongside South Africa. OEC, using an HS96 methodology, records a slightly different rank of 50th, having moved from 60th to 50th over two decades, with the discrepancy reflecting methodology rather than substance. Harvard assesses Tunisia as more complex than expected for its income level and projects around 3.3% annual growth to 2034, placing it in the top half of countries. The strategic implication is that Tunisia already possesses the diversified productive know-how, in electricals, light machinery, chemicals and precision assembly, that most African economies lack; its binding constraint is scale, capital and market orientation, not capability.
OEC records Tunisia exporting 239 products with a revealed comparative advantage above 1. The highest-specialisation lines are Pure Olive Oil (RCA index 87.8), Flax Yarn (59.2), Phosphatic Fertilizers (55.4), Phosphoric Acid (46.5) and other Olive Oil (40.9), with RCA above 1 also covering insulated wire, non-knit suits, dates, electrical switching apparatus and vehicle parts. Crucially, the highest-PCI, most knowledge-intensive exports include auxiliary machinery for textile machines, flow, level and pressure measuring instruments, and additive-manufacturing machines, evidence of latent sophistication that sits above the country's current income and scale. The picture is of an economy whose product space is unusually deep for the region but whose output remains EU-captured and fiscally constrained.
The trump card · the single strongest continental position
Tunisia's one category to anchor continental supply is automotive wiring harnesses and insulated wire (HS8544). It is the country's single largest export, recorded at USD 2.99 billion by TrendEconomy and USD 3.23 billion by OEC in 2023, equivalent to roughly 14.9% of all merchandise exports and making Tunisia the 13th-largest global exporter of insulated wire, with Germany, France and Italy the top destinations. Production is anchored by a mature multinational ecosystem, Leoni, Yazaki, Sumitomo and Dräxlmaier among others, serving European automakers and drawing on a proven engineering and assembly workforce. As African vehicle assembly expands in Morocco, Egypt and South Africa, harnesses are the highest-value, most labour-embedded input that African plants cannot yet source at scale on-continent, and Tunisia already makes them to European OEM standards. No other African economy combines this depth, quality certification and cost position; the audit judges this to be capability that exists today, not aspiration.
The honest limits are structural rather than technical. The capacity is contractually embedded in EU value chains under the offshore regime, so a continental pivot must run on incremental, ring-fenced African-destined lines rather than the substitution of existing higher-margin EU volumes, or it risks cannibalising the very base that makes the cluster credible. Delivery therefore depends on operationalising AfCFTA rules of origin and PAPSS payments so goods clear duty-free, and the audit's own recommendation is to first quantify spare and incremental capacity across the Leoni, Yazaki, Sumitomo and Dräxlmaier plants; if audited spare capacity is below about 10% of output, the anchor emphasis would shift toward fertilisers. Within those conditions, Tunisia could credibly serve as the continent's harness and cable hub, redirecting incremental capacity toward African assemblers while retaining its EU base.
