Import a Copper SX-EW Plant to Uganda (2026)

A copper SX-EW plant enters Uganda at zero customs duty, with the 18 percent import VAT deferrable for registered importers. The buyer behind the search is the Kilembe redevelopment: Uganda signed its first mineral production sharing agreement on 3 March 2025 to restart a deposit holding more than 6.5 million tonnes of ore at 1.77 percent copper.

Before any of the import mechanics matter, though, there is a flowsheet question that most equipment suppliers skip, and skipping it wastes everyone’s time. This page covers both: whether Kilembe is really an SX-EW project, and then, for whichever hydromet package does get bought, how the equipment physically and financially gets from your works to western Uganda.

Check the flowsheet before you quote

Solvent extraction and electrowinning earns its keep on feed that leaches in acid: oxide ores, supergene material, or leach liquor from a concentrate or tailings treatment step. Kilembe is not an oxide deposit. Its copper sits in sulphide mineralisation, and its cobalt sits in pyrite, which is why the one hydrometallurgical plant ever completed at the site was a bioleach, not a heap leach.

The government’s announced end products are copper cathodes and cobalt metal, per the Directorate of Geological Survey and Mines. Cathode output implies electrowinning somewhere in the chain. What has not been published is the route to it: a flotation concentrator feeding a smelter abroad, a concentrate leach, a tailings retreatment circuit, or some staged combination. Each of those buys a different equipment list, and only some of them include an SX train.

So the honest advice to a vendor is to sell against the blocks that survive every scenario first. Crushing, grinding, thickening, materials handling, tailings, water treatment, and the cobalt-side leach and EW package all have a place in any credible Kilembe flowsheet. A full copper heap-leach SX-EW package, the Zambian or Chilean pattern, may never be tendered here. Ask the developer’s engineers what the definitive study assumes before you build a bid around it.

Who signed, and where the project stands

The counterparty is named and private. Sarrai Group Limited and Nile Fibreboard Limited won the redevelopment against 14 competing bidders, and the production sharing agreement they signed in March 2025 was the first of its kind under Uganda’s mining law. The state’s commercial interest runs through the Uganda National Mining Company, so this is a private-led project with a government shareholder rather than a parastatal tender.

The asset itself is broader than a mine. The energy ministry describes it as a greenfield exploration area, a brownfield copper mine, a processing plant, and cobalt-rich tailings, per Mining Weekly’s report on the signing. The deposit figures on the government side are 6.5 million tonnes at 1.77 percent copper plus 5.5 million tonnes at 0.17 percent cobalt. Kilembe last produced at scale in the early 1980s, so almost everything on site dates from that era and the realistic assumption is new plant, not refurbishment.

Sarrai is the same Ugandan industrial group that owns Hima Cement, which tells you two useful things: it self-delivers large projects through appointed contractors, and it already has trade-finance relationships with the Kampala banks. The wider buyer map for the sector sits in our Uganda mining and minerals guide.

Uganda has run SX-EW before, on cobalt

The country is not new to this technology, and the precedent shapes where the near-term demand sits. The Kasese Cobalt Company plant, on the valley floor below the Kilembe mine, bioleached the mine’s stockpiled cobalt-rich pyrite in stirred tanks and recovered the metal as cathode through solvent extraction and electrowinning. At peak it produced about 1,100 tonnes of cobalt cathode a year, and it stopped in 2013 only because the stockpile ran out, per a peer-reviewed bioleaching review.

That history matters to a supplier in three ways. First, the cobalt lane is the proven SX-EW conversation at Kilembe, and the redevelopment package explicitly includes cobalt-rich tailings. Second, a bioleach-SX-EW restart is a brownfield-adjacent sell: the site once held acid handling, mixer-settlers, and a tankhouse, and the developer’s engineers will benchmark new quotes against that institutional memory. Third, thirteen years of standstill means the old equipment is a reference point, not a competitor.

What the plant pays at the border

Uganda treats imported process plant gently, and quoting the fiscal position correctly is an easy credibility win with the buyer’s finance team.

Charge	Treatment for SX-EW plant and equipment (HS 84/85)
Import duty (EAC CET)	0 percent as capital goods
VAT	18 percent, deferrable at import for VAT-registered importers, per PwC’s Uganda tax summary
Import declaration fee	1 percent of customs value; plant and machinery exempt under the 2025 external-trade amendments
Infrastructure levy	1.5 percent of customs value; same exemption applies

The deferment mechanics reward a supplier who knows them. The importer declares the deferred VAT in its return rather than paying cash at the border, and the URA discharge application falls due within 28 days of the deferment period ending, backed by evidence the machinery is installed. On a plant-scale invoice, not tying up 18 percent at the port is real working capital, and it can decide which budget year the order lands in.

Freight: Mombasa is only half the journey

Every tonne of an SX-EW plant reaches Uganda by sea to Mombasa and then by road up the Northern Corridor, crossing at Malaba or Busia. Kenya moved on the corridor’s chokepoints in April 2026 with a reform package, including the removal of police roadblocks, that targets cutting Mombasa-to-Malaba transit from 76-80 hours to 36-48 hours. Plan on the old numbers until the new ones are proven, and remember Kasese sits another 400-plus kilometres west of Kampala. The standard gauge railway is under construction and irrelevant to any delivery quoted in the next few years.

The cargo profile is what makes hydromet freight distinctive. Mixer-settler tanks and cells are bulky but light, so they price on volume and often justify shipping as panels and linings for site assembly by a local fabricator. Rectifier transformers and overhead cranes are the abnormal loads that need escort planning and route surveys on the inland leg. Splitting the scope that way, engineered components from the OEM, tankage and structural steel fabricated in Uganda or Kenya, cuts landed cost and scores local-content points with the developer.

Consumables deserve a line in the same freight plan, because they decide the operating case. An operating SX-EW circuit drinks sulphuric acid and organic extractant continuously, and Uganda produces neither at scale, so every year of operation rides the same corridor as the plant did. A vendor who shows up with a reagent logistics plan, not just an equipment quote, is answering the question the feasibility engineers are actually stuck on.

Paying for it: shillings, letters of credit, and cover

The Uganda shilling floats with central bank smoothing, and capital-goods importers face no allocation queue for dollars. Price 2026 offers inside a UGX 3,450 to 3,800 per dollar band and invoice in dollars or euros; a copper project’s revenue is dollar-denominated anyway, so the currency match is natural.

Plant-scale letters of credit clear through Stanbic, Absa, Standard Chartered’s corporate desk, dfcu, or Centenary, with confirmation typically added in London, Frankfurt, or Dubai. The customary shape is an advance against bank guarantee, the bulk against shipping documents, and retention to commissioning. Export-credit cover follows origin: Sinosure for Chinese-built packages, UKEF, Euler Hermes, or SACE for European ones, and on a first-of-its-kind Ugandan copper project the financing wrap will be weighed as heavily as the metallurgy.

Where the RFQs will surface

Do not wait for a portal. As a private developer, Sarrai Group procures through its own project team and whichever EPC or EPCM house it appoints, so the entry point is vendor registration with the group and a technical relationship with the study engineers while the flowsheet is still open. The state-side slice is smaller: work funded through UNMC or the ministry runs under public procurement rules, and Uganda’s e-GP portal became mandatory for all public procuring entities on 1 July 2026, so register once and set category filters.

One registration you do not need: the Petroleum Authority’s National Supplier Database covers the oil and gas chain only. Mining suppliers sell direct. Country-level context on banking, tax, and logistics sits in the Uganda industrial procurement guide.

The channels that will not sell a leach plant

The conventional routes into East African mining were built for consumables and commodity kit, and a configured hydromet plant defeats all of them. Mining Indaba in Cape Town is where Uganda’s ministerial delegations appear, but it runs at investment level; the engineers writing Kilembe’s equipment list are not walking the aisles. The Uganda International Trade Fair at UMA’s Lugogo grounds in Kampala is a consumer-goods and SME show, and no one specifies a tankhouse from a stand there.

A resident field rep covering one pre-FID copper project is an impossible cost case, and Kampala’s importer-distributor houses stock pumps and spares, not solvent extraction circuits. The Chinese and Indian supply channels attached to the region’s contractors are effectively closed loops; if you are not already inside one, a distributor will not pull you in. What works is direct, early, technical contact with the named developer and its study engineers. That is the channel papaverAI runs: systematic outbound at USD 150 to 300 per qualified lead, and unlike a fair budget that starts from zero each year, the cost per lead falls as the engine learns the buyer set.

FAQ

Will the Kilembe redevelopment buy a copper SX-EW plant or a concentrator?

Unpublished so far. The ore is sulphide, which conventionally points to flotation and a concentrate route for the copper, while the cobalt in the tailings has a proven bioleach-SX-EW history on site. Suppliers should track the developer’s feasibility work and quote against the flowsheet blocks that appear in every scenario.

Do SX-EW equipment suppliers need Uganda’s National Supplier Database registration?

No. The NSD run by the Petroleum Authority of Uganda is a precondition for the oil and gas supply chain only. Mining equipment sells directly to the project companies, or through the e-GP portal at egpuganda.go.ug where the buyer is a public entity spending government funds.

How long does delivering an SX-EW package to western Uganda take?

Indicatively: four to six weeks of ocean freight to Mombasa, several days to a week up the Northern Corridor to Kampala, then the 400-plus kilometre leg to Kasese, longer for abnormal loads needing escorts and route surveys. Door to door, plan months, and sequence heavy electrical items around bridge and road constraints.

Can an SX-EW plant in Uganda count on grid power?

Electrowinning is a continuous, power-hungry load, and Uganda’s generation position is stronger than it has ever been, with the 600 MW Karuma plant commissioned in 2024. A cellhouse still needs a dedicated supply agreement and backup strategy, so put the power study in the same workstream as the equipment specification.
