The Comsigua DRI plant began operations in 1998 as a joint venture between Kobe Steel, Tamsa México, and the Corporación Venezolana de Guayana.[2] The plant's full name - Complejo Siderúrgico de Guayana - reflects the owners' original vision of creating a larger steel complex comprising two DRI plants, an EAF melt shop and continuous casting facilities.[2] However, financial concerns caused the project to be limited to iron reduction only.[2]

Comsigua produced more than 1 million tonnes of briquettes annually during its first several years of operation, but production dropped off sharply after the plant was nationalized in 2009.[2] Tenaris, the parent corporation of Tamsa México, successfully brought legal charges for breach of international treaty, forcing the Venezuelan government to pay compensatory damages of US $31.7 million in 2011.[2] Comsigua's DRI production, which plummeted to near zero by 2016[2], has recovered somewhat in recent years but continues to be negatively impacted by Venezuela's fragile economy. Comsigua barely achieved 25% of its operational capacity in 2020, and workers have reported that the plant is falling apart and in serious need of new investment.[3]
