The surging global demand for critical minerals has sparked a renewed scramble for these strategic resources, posing significant challenges for producing countries as they seek to capture a fair share of the economic rents generated. Critical minerals differ from conventional extractive commodities in that the location of rent generation is moving downstream—from the mine to the plant—and toward intangible assets, including proprietary technologies, patents, and digital servitization platforms. Following a brief review of standard mining taxation instruments, this paper turns to China’s fiscal approach, which is central in the global critical minerals’ ecosystem. Drawing on this case, the paper outlines potential tax policy reform options for resource-rich economies. These include: (i) anchoring production pricing to transparent international benchmarks to mitigate transfer pricing abuses; (ii) establishing ring-fencing provisions for critical minerals produced predominantly as by-products; (iii) reasserting the source principle in bilateral and multilateral tax arrangements; (iv) revisiting the strict application of the VAT destination principle, particularly for unprocessed mineral exports; and (v) exploring the potential role for regional cooperation and international institutions.
