What is the ruling on selling a portion of the raw materials provided by the financing entity for the bakery project for manufacturing purposes?

If the bakery is yours, and the ingredients were purchased by a party, then you bought them from that party and took possession of them, they become your property, and you are permitted to dispose of them by selling or utilizing them without seeking permission. If they stipulated that you should not sell them, then this condition is void because it contradicts the intended purpose. However, if your role is solely administrative, then it is appropriate to consult them regarding unauthorized dispositions.
