The Kalaye Electric Company was a small workshop on the outskirts of Tehran that served as Iran's primary centrifuge R&D and pilot enrichment facility between 1995 and 2002.  After media reports revealed its existence, the IAEA asked to visit the facility in February 2003. Tehran initially denied the IAEA request and engaged in substantial concealment efforts, such as renovating the entire facility and removing equipment.  When Iran eventually granted the IAEA access to the site in March 2003, Tehran prohibited the Agency from taking environmental samples.  However, Iran allowed the IAEA to take environmental samples during a subsequent inspection in August 2003. These samples revealed the existence of undeclared nuclear material, including natural, depleted, low, and highly enriched uranium.  Iran later admitted that it had used the facility for the production of centrifuge components and had conducted some testing with uranium hexafluoride (UF6), including the introduction of UF6 into a 19-machine cascade in 2002. 
At the end of 2002, Tehran had moved all enrichment equipment to the new Pilot Fuel Enrichment Plant in Natanz and began using the Kalaye Electric Company for centrifuge component production.  In 2006, United Nations Security Council Resolution 1737 placed sanctions on the Kalaye Electric Company for supporting Iranian proliferation activities. The resolution blocked the company from importing or exporting sensitive nuclear material and equipment and froze its financial assets.
