While S. K. Manjul regards the OCP to be a culture which developed independent from the (Late) Harappan culture, according to archaeologist Akinori Uesugi (2018, p. 6) Ochre Coloured Pottery culture (c. 1900-1300 BCE), to which Sinauli's burials belong, was a Late Harappan expansion of the previous Bara style (c. 2300-1900), a regional culture of the Harappan civilization from the Ghaggar valley, calling it the Bara-OCP cultural complex: "During the early second millennium BCE, the Bara-OCP (Ochre-Coloured pottery) cultural complex expanded from the Ghaggar valley to the western part of the Ganga valley. This cultural complex [...] has its origin rooted in the Indus Civilization in the preceding period, its eastward expansion indicates the colonization of the western Ganga valley probably giving great impetus to the Neolithic-Chalcolithic communities in the Ganga valley to transform into a more complex society."
