The appropriate TTB officer shall make investigation and take such action as the facts may warrant. Where the detained merchandise has been withdrawn for transfer and deposit in a manufacturing bonded warehouse, the merchandise shall be deemed not to have been deposited in said warehouse, and the designated officer shall hold in abeyance the processing of TTB Form 5100.11 until advised by the district director of customs that the detained merchandise may be entered for deposit. Where the detained merchandise has been withdrawn or entered for deposit in a foreign-trade zone or a customs bonded warehouse, it shall be deemed to not have been deposited in the zone or the warehouse and the customs officer shall hold in abeyance the processing of the application, notice, or claim, TTB Form 5100.11, 5110.30, 1582–A (5120.24), 1582–B (5130.6), or 1689 (5130.12), as the case may be, and Zone Form D, until advised by the district director of customs that the detained merchandise may be entered for deposit.
