Imjin Mill Foreman’s Office is a Rare key in MW4 DMZ. It opens the foreman’s office at the Rice Mill in Imjin Farmland, a suite of small rooms upstairs that the game labels Mill Foreman Office. Below is where the door is, the route from the packaging hall and everything we found in its 17 containers.
- The door is at the Rice Mill in Imjin Farmland, grid D8, upstairs next to a sign that reads Office.
- Go in through the packaging hall marked 04, take the metal stairs up and follow the walkway and covered corridor.
- Behind the door are a few small rooms with 17 containers, mostly military lockers and ammo boxes.
- Ours held an Encrypted Archive, Infantry Invasion Plans and an Epic Medkit, at least $6,750 in loot.
- Only worth it if you are already at the Rice Mill. The loot is not great.
Where the Imjin Mill Foreman’s Office Door Is
The foreman’s office is at the Rice Mill in Imjin Farmland, grid D8. The way in is the packaging hall, the white building with a Packaging sign and the number 04 next to its open roller door. The office itself is upstairs, a plain wooden door with a sign that reads Office next to it. The Rice Mill was a Medium threat area in our run. You can also find the door under the keys layer on our interactive MW4 DMZ map.

How to Get the Imjin Mill Foreman’s Office Key
The Imjin Mill Foreman’s Office key is field loot, so it can drop from ordinary containers on Hajin. We do not know of a fixed spawn for it. On another run one came out of a jacket in Mirae General Hospital, where the Hospital Chemical keys are too, but keys roll randomly, so do not count on that spot. Every other key and the door it opens is in our MW4 DMZ keys guide.
The Route to the Door
- Walk into the packaging hall through the open roller door marked 04.
- Take the metal stairs just inside on the right up to the walkway, and follow it past the double doors with the Grain Silo sign.
- Go through the covered corridor with the barred windows. At the end, turn to the door with the Office sign and use the key.
What Is Inside the Imjin Mill Foreman’s Office
The door opens into an office, and from there a few small rooms connect to each other, one with a map table and one with bunk beds and a workbench. All 17 containers are in those rooms, so you can loot the whole suite without going back outside. Clear the rooms first, because AI can be inside.

From one opening in our own run. Loot is random, so your room can roll differently, and we add every new run of this key. Values are per item, from the in-game tooltips. The loot value adds up every item with a known value and the cash, so it is a lower bound: crafting resources and items without a value are not in it.
Most of it is gear. Six military lockers, two footlockers and two military bags held medical items, lethals, tacticals and armor plates, with a few crafting parts and resources on the side. The green weapons cabinet, which the game calls a Cache, gave the best spread, a Defibrillator, a Recon Drone and Infantry Invasion Plans. The rifle case on the workbench held a Rezi 12 shotgun and an Encrypted Archive worth $2,000, the most valuable item of the run. One military locker also had an Epic Medkit. Counting only items with a known value, the loot in the rooms was worth at least $6,750.

Is the Imjin Mill Foreman’s Office Key Worth It?
Only if you are already at the Rice Mill. The loot is not great, mostly gear and crafting parts, so it is not worth a trip on its own. If you are there anyway, the climb from the packaging hall is short and the 17 containers sit close together, and the Hoesik Supply Room is a short walk away.
