OECD and IGF: Lithium Price Framework by Transfer Pricing

August 16, 2024

Background

Transfer Pricing is fundamental in globalized economies, especially in highly internationalized industries such as mining. These prices refer to the values at which transactions among companies of the same multinational group under the Arm’s Length principle, i.e., be comparable to those applied among independent companies. In the mining sector, specifically for lithium, the correct application of these principles is essential to avoiding tax base erosion and ensuring that producing countries, such as Argentina, Bolivia, and Chile, rich in lithium reserves, receive a fair share of the revenues generated by their natural resources, reflecting actual market conditions.

Transfer Pricing in Lithium Mining

Transfer Pricing is essential to prevent mining multinationals from using differences in tax regimes in different jurisdictions to shift profits to low-tax countries, a practice that significantly reduces tax revenues in developing countries. In the lithium industry, the complexity of the value chain, which includes extraction, processing, and international marketing, makes the application of Transfer Pricing particularly relevant.

The recommended and most widely employed approach to ensure that Transfer Pricing respects the Arm’s Length Principle is the Comparable Uncontrolled Price (CUP) method, which compares prices charged in controlled transactions (among companies of the same group) with prices charged in independent party transactions in comparable circumstances. For lithium, the proposed framework considers three key factors: First, product characteristics involve the purity of the lithium, its origin (brines or hard rock), and concentrations. Second, economic conditions entail the circumstances of the sale (global demand, technological advances, or changes in environmental regulations). Third, contractual terms involve the terms and conditions of related party transactions (payment terms, delivery conditions, transportation costs, and any other relevant factors).

Conversely, the volatility in lithium prices presents an additional challenge. Its high demand has generated fluctuations in its price in international markets. Therefore, producing countries must use price references from reliable sources, such as the Fastmarkets and Argus Media indices, which publish data on lithium sales prices in different markets. These indices allow tax authorities to establish reference prices reflecting market conditions, ensuring controlled transactions comply with international regulations.

Challenges and Opportunities for Developing Countries

One of the biggest challenges facing developing countries is the lack of access to reliable information on international lithium transactions and the limited administrative and technical capacity to regulate these transactions adequately. It can lead to aggressive tax planning practices by multinational mining companies, reducing tax bases and tax revenues in the countries where extracting the resources.

The recommendation is for countries to implement Advance Transfer Pricing Agreements (APAs) to mitigate these risks. These agreements allow companies and tax authorities to fix in advance the prices applicable to controlled transactions, thus reducing uncertainty and ensuring stability in tax revenues. APAs are particularly useful in the lithium context, where price fluctuations and the complexity of value chains can create uncertainty for companies and governments.

In addition, lithium-producing countries must strengthen their capacity to monitor and regulate international transactions by improving data collection, using reliable reference prices, and strengthening international cooperation in the fight against tax evasion.

In conclusion, the proposed framework for Transfer Pricing in the sale of lithium provides a comprehensive guide for developing countries to protect their tax interests against aggressive planning by multinationals. By applying the CUP method and considering product characteristics, economic conditions, and contractual terms, tax authorities can ensure that related party transactions reflect market prices and do not harm local tax revenues.

Tax authorities in developing countries should also use prices quoted in international markets, such as those published by Fastmarkets and Argus Media, to establish reference prices. These indices reflect market fluctuations and can be adjusted according to the specific characteristics of the lithium traded, such as purity and transportation costs.
