ILAB has reason to believe that indium produced in South Korea is produced with an input produced with child labor, specifically zinc mined in Bolivia. Zinc from Bolivia was added to ILAB’s List of Goods Produced by Child Labor or Forced Labor in 2010 for child labor. Boys as young as age 13 commonly work in underground mines in Potosi and Oruro, where they are subjected to hazardous working conditions including narrow tunnels, heavy machinery, extreme temperatures, and exposure to dust and chemicals without ventilation. These conditions are widely found in the cooperatives sector, which produces 18% of Bolivia’s zinc. Zinc ore in Bolivia contains some of the world’s richest concentrations of indium, but workers are not compensated for the indium found in the zinc that they mine. Zinc concentrate from multiple sources is often mixed together, blending responsibly mined zinc with zinc mined with child labor, and subsequently exported. In 2022, South Korea imported over $385 million in zinc concentrate from Bolivia, representing 16.3% of its zinc concentrate imports, and some of these imports connected to child labor in the cooperatives sector in Bolivia were used to produce indium. South Korea is the world’s second-largest producer of indium, producing 22.2% of the global supply in 2022. This research suggests that further worldwide downstream products of zinc and indium, such as conductive glass, touchscreen devices, flatscreen devices, televisions, phones, tablets, semiconductors, solar panels, indium-tin oxide, and LEDs may be produced with an input produced with child labor.
