During the third Millennium BCE, grey wares were the most popular wares in the Indo-Iranian borderlands inwhich the Bampur Valley and the Sistan basin played a significant role. This research aims to compare grey waresof the above-mentioned regions in order to have a better understanding of possible cultural similarities in bothregions. Similarities between grey wares of the regions at the issue have been frequently explained in the light ofthe long-distance trade mechanism, and considered as a result of the (intentional or unintentional) exchange ofpottery techniques and design styles through commercial activities. Eighteen Grey ceramic sherds were sampledat Tepe Bampur and Shahr-i Sokhta, two key-sites, which are respectively located in the Bampur Valley and theSistan Basin. To compare the raw materials of the ceramic samples after their analyses, some clay samples were alsocollected from two specific natural clay deposits, located ۱۰ km north and ۴۵ km south of Shahr-i Sokhta, and fromthe bank and riverbed of the Bampur River. In addition, a clay sample was also collected from a clay deposit in thePirgel region, located ۱۰۰ km north of Tepe Bampur and ۳۰۰ km southwest of Shahr-i Sokhta. By means of XRFtechniques, it was attempted to compare different elements of the ceramic and soil samples. The results show thatthere are close similarities between the chemical elements of the grey wares collected at Shahr-i Sokhta and TepeBampur and soil samples from the Bampur Valley and the Pirgel region. Although these similarities are not seenwith soil samples of the Sistan Basin, the grey wares of these two sites were completely similar. Finally, it can bestated that the fine grey wares of the Sistan Basin were not locally manufactured but were probably imported fromthe Bampur Valley and other regions through long-distance trade during the third millennium BCE.
