In the new regulations, it states that qualified inventory is deemed in transit if it is moving from vendor to a facility of the trade or business that is in a QOZ, or from a trade or business that is in a QOZ to a customer outside the QOZ. The regulations do not designate exact timing, but presumably from purchase date onward for inventory from vendor, and until delivery by carrier to the customer. The regulations likely will not make an exact measurement upon when the safe harbor will apply.
