Overview & History
The DRC's Mining Code (Code Minier) is the foundational legislation governing the exploration, extraction, processing, and commercialisation of mineral resources in the country. The current code, enacted in March 2018 as Law No. 18/001, represents a comprehensive revision of the 2002 Mining Code that had governed the sector through the DRC's post-conflict mining boom.
The 2002 Mining Code, developed with World Bank technical assistance, was deliberately liberal in design — intended to attract foreign investment to a mining sector devastated by decades of mismanagement under Mobutu and the disruptions of the Congo Wars. It offered low royalty rates (2 percent for base metals), generous stability clauses that protected investors from legislative changes for 10 years, favourable tax depreciation schedules, and streamlined permitting procedures. The code succeeded in its primary objective: mining investment surged, production recovered, and the DRC re-established itself as a major copper and cobalt producer.
However, by the mid-2010s, a consensus had formed within the DRC government and civil society that the 2002 Code gave too much to investors and too little to the Congolese state and communities. Mining revenues, while growing in absolute terms, represented a smaller share of the sector's value than in comparable jurisdictions. The stability clauses prevented the government from adjusting terms as commodity prices rose. And the code's provisions for community development and environmental protection were widely regarded as inadequate and poorly enforced.
The 2018 revision was the result of several years of negotiation between the government and the mining industry. Mining companies, led by the industry association FEC and international chambers of commerce, lobbied intensively against many of the proposed changes. President Joseph Kabila signed the revised code into law despite industry objections, and the implementing regulations were subsequently enacted.
Key Provisions of the 2018 Code
The 2018 Mining Code introduced changes across virtually every dimension of the regulatory framework. The most consequential provisions relate to fiscal terms, strategic mineral classifications, state participation rights, and the legal protections available to mining companies.
| Provision | 2002 Code | 2018 Code |
|---|---|---|
| Copper Royalty Rate | 2% | 3.5% |
| Cobalt Royalty Rate | 2% | 3.5% (10% as strategic mineral) |
| Gold Royalty Rate | 2.5% | 3.5% |
| Diamonds Royalty Rate | 2.5% | 3.5% |
| Strategic Mineral Surcharge | None | Up to 10% royalty rate |
| Super-Profits Tax | None | 50% on excess profits |
| Stability Clause Duration | 10 years | 5 years |
| State Free-Carry Interest | 5% | 10% |
| Community Development Contribution | 0.2% of turnover | 0.3% of turnover |
| Repatriation of Export Proceeds | 40% within 15 days | 60% within 15 days |
Royalty Structure
The 2018 Code significantly increased royalty rates across all mineral categories. For copper, the standard royalty rose from 2 percent to 3.5 percent of the gross commercial value of production. For cobalt, the rate also increased to 3.5 percent under standard classification, but the designation of cobalt as a "strategic substance" (substance strategique) permits the government to impose a royalty of up to 10 percent — a provision that was activated in practice when cobalt was formally designated as strategic.
Royalties are calculated on the basis of gross commercial value — the value of the mineral product at the point of sale minus allowable transport and insurance costs. This calculation method has been a source of dispute, as mining companies and government auditors frequently disagree on the applicable deductions. Transfer pricing concerns are particularly acute for companies that sell to affiliated trading entities, raising questions about whether reported sale values accurately reflect market prices.
The royalty regime applies differently to industrial and artisanal mining. Artisanal miners and their cooperatives are subject to simplified fiscal arrangements, though in practice tax compliance in the artisanal sector is minimal. The EGC's monopoly on artisanal cobalt purchasing was intended in part to facilitate revenue collection from the artisanal sector, though implementation challenges have limited its fiscal impact.
Strategic Minerals Designation
One of the most significant innovations of the 2018 Code is the concept of "strategic substances" (substances strategiques). The code empowers the government to designate any mineral as strategic by presidential decree when it is deemed to be of particular importance to the national economy. Strategic mineral designation triggers several consequences: royalty rates can be increased to up to 10 percent; additional government oversight and approval requirements apply to production and export decisions; and the government retains enhanced rights to intervene in the supply chain.
As of 2025, the following minerals have been designated as strategic substances:
| Mineral | Designation Date | Royalty Rate | Rationale |
|---|---|---|---|
| Cobalt | 2018 | Up to 10% | Global supply dominance, battery demand |
| Coltan (Tantalum) | 2018 | Up to 10% | Electronics industry importance |
| Germanium | 2018 | Up to 10% | Semiconductor applications |
| Lithium | 2023 | Up to 10% | Battery value chain potential |
The strategic mineral designation has been both praised and criticised. Advocates argue it gives the DRC appropriate leverage over minerals for which it holds dominant global market positions. Critics, including many mining companies, argue that the designation introduces regulatory unpredictability — the government can change the royalty rate for strategic minerals without the legislative process required for a formal code amendment, creating uncertainty for investment planning.
The strategic mineral framework provided the legal basis for the DRC's 2025 cobalt export intervention, demonstrating its practical significance. The government argued that its authority over a designated strategic substance permitted it to restrict exports in the national interest — a position that has precedent in other resource-rich countries but nonetheless unsettled investors accustomed to the more permissive 2002 regime.
Super-Profits Tax
The 2018 Code introduced a super-profits tax (Impot sur les Super Profits) that applies when a mining company's operating margin exceeds the margin projected in its original feasibility study by more than 25 percentage points. In such circumstances, the excess profit is subject to a 50 percent tax, payable in addition to standard corporate income tax (30 percent) and royalties.
The super-profits tax was designed to capture windfall gains when commodity prices rise substantially above the levels assumed when mining investments were approved. In principle, it ensures that the state shares in commodity upswings. In practice, the tax has proven difficult to administer and contentious in its application.
The principal challenge lies in determining the benchmark against which super-profits are measured. Feasibility studies submitted at the time of permit applications may not reflect current cost structures, production volumes, or processing configurations. Mining companies argue that comparing actual margins to historic feasibility projections is inherently unreliable and penalises operational improvements. Government auditors counter that companies systematically understate projected profitability in feasibility studies to establish artificially low baselines.
As of 2025, the super-profits tax has generated limited revenue relative to its theoretical potential. Several major mining companies have challenged assessments through administrative appeals and arbitration proceedings. The tax remains a source of friction between the government and the mining sector.
Stability Clauses
Stability clauses in mining legislation are contractual or legislative provisions that protect investors from changes in the fiscal or regulatory regime for a specified period. The 2002 Code provided robust stability protections: for 10 years from the date a mining permit was granted, the holder was protected against any change in the fiscal, customs, or exchange control regime that would adversely affect its investment. This provision was a key attraction for early investors in the DRC's post-conflict mining revival.
The 2018 Code reduced stability clause protections in two significant ways. First, the duration was shortened from 10 years to 5 years. Second, the scope was narrowed — the new stability clause does not protect against changes in royalty rates for strategic minerals, does not prevent the application of the super-profits tax, and does not limit the government's ability to require repatriation of export proceeds.
The transitional provisions of the 2018 Code generated particular controversy. Mining companies argued that their existing stability protections under the 2002 Code should be honoured until their expiry. The government's position was that the 2018 Code superseded the 2002 provisions and that the new fiscal terms applied immediately to all operations. After extensive negotiation, a compromise was reached under which companies that had invested under the 2002 Code received a transitional period of reduced impact, but the fundamental principle that the new code applied to existing operations was upheld.
The weakening of stability protections remains one of the most frequently cited concerns among mining investors in the DRC. Investment decisions in the mining sector involve capital commitments of hundreds of millions or billions of dollars over project lives of 20 to 40 years. The ability of the government to alter fiscal terms within the life of a project introduces a risk premium that affects project economics and, by extension, the volume of minerals available for transport through the Lobito Corridor.
OHADA & Legal Framework
The DRC became a member of OHADA (Organisation pour l'Harmonisation en Afrique du Droit des Affaires) in 2012, joining 16 other African countries in a framework for harmonising business law. OHADA's Uniform Acts cover commercial law, company law, secured transactions, insolvency, accounting, and arbitration, among other areas. The DRC's accession was intended to improve legal certainty and reduce the perception of regulatory risk.
OHADA provides a framework for commercial dispute resolution through the Common Court of Justice and Arbitration (CCJA) in Abidjan, offering an alternative to DRC domestic courts, which are widely perceived as lacking independence and predictability. Several mining disputes have been referred to OHADA mechanisms, though the relationship between OHADA commercial law and the DRC's sector-specific mining legislation (which is not harmonised under OHADA) creates jurisdictional complexity.
The mining code operates within a broader legal framework that includes the DRC Constitution (which vests mineral resources in the state), the Investment Code, the Foreign Exchange Regulation, environmental legislation, and various presidential decrees and ministerial orders. The interaction between these instruments is not always consistent, and the practical application of law in the DRC is significantly affected by institutional capacity constraints, corruption, and the limited reach of the formal legal system outside major urban centres.
For investors in the Lobito Corridor, the legal framework is directly relevant. The corridor's infrastructure concessions, mineral offtake agreements, and cross-border transport arrangements all operate within the DRC's legal environment. Regulatory risk — the possibility that the government will change the rules in ways that affect project economics — is consistently cited as one of the most significant obstacles to investment in the DRC's mining and infrastructure sectors.
Impact Assessment
The 2018 Mining Code has had measurable impacts on the DRC's mining sector and broader economy, though its effects are debated.
Positive Impacts
Government revenues from mining have increased, both as a result of higher royalty rates and growing production volumes. The strategic mineral designation has given the government a tool to exert influence over critical supply chains, as demonstrated by the cobalt export intervention. The increased community development contribution (from 0.2 percent to 0.3 percent of turnover) has in principle directed more resources to mining-affected communities, though the actual expenditure and quality of community projects varies widely.
Negative Impacts
Several planned mining investments have been delayed or scaled back in response to the higher fiscal burden and reduced stability protections. The regulatory uncertainty associated with the strategic mineral designation and the super-profits tax has increased the DRC's risk premium relative to competitor jurisdictions. Some companies have redirected investment toward Zambia, which offers a more predictable (though not necessarily more favourable) fiscal regime. The complexity of the 2018 Code and its implementing regulations has also increased compliance costs, particularly for mid-tier operators without dedicated regulatory affairs teams.
Corridor Implications
The mining code directly affects the Lobito Corridor's commercial prospects. Higher fiscal burdens can reduce the profitability of mining operations, potentially limiting expansion plans and the volume of minerals available for corridor transport. Conversely, the government's ability to direct mineral exports through the corridor — as contemplated in the US-DRC Strategic Partnership Agreement — depends on the regulatory authority established under the mining code. The interaction between mining regulation and corridor economics will be a defining dynamic for both the sector and the infrastructure project in the years ahead.
