Resources Hearts of Iron IV Guide
Last update: 06 July 2016
The below chapter provides all of the information on all resources available in the game. You have to remember that there are filters that will help you find information on resources available in individual regions.
While planning on expansion into individual territories, you first have to obtain intel on resources and define your war goals basing on that. If you want to wage a war against another nation, it would be good to get something more from it, than just a strip of land for building new factories. Of course, your territorial expansion will result in greater amount of resources at your disposal. This is when to take a closer look at your trade policy and decide whether all of the agreements are really as profitable and as necessary.
Oil
In this case, apart from geologic resources, you can also take advantage of synthetic refineries. Thanks to this, you do not have to only rely on basic resources available in the region, but also you can obtain the material thanks to technologies that you develop.
Construction | Demand |
Aviation | Low |
Navy | Medium |
Cars | Low |
Mechanized units | Medium |
Mechanized artillery | Medium |
Tanks | Low |
Note: You can easily note that, when it comes to oil, it is material that is required for construction of many units, but its supply is not the key for their production. Thanks to several refineries and trade contracts, you can establish many production lines for the above types of units without worrying that you will run out of supply of oil to maintain military and civilian factories in full operation.
Aluminum
Mining for natural resources is the only way of obtaining aluminium. If your factories cannot satisfy your needs, you will have to take advantage of trade agreements.
Construction | Demand |
Aviation | High |
Gear for support battalions | Low |
Note: Aluminum is the basic material that you use in production of all types of planes. If you decide to develop aviation, remember that you should obtain as much of this material as possible. Also, you will require it for production of gear for support battalions, but demand here is not as high.
Rubber
Just like in the case of oil, you can obtain rubber from synthetic refineries. In this case, the income from trade may not be as high, but they should satisfy low demand.
Construction | Demand |
Aviation | Medium |
Cars | Low |
Mechanized vehicles | Low |
Mechanized artillery | Low |
Note: Rubber is necessary to build all types of planes. Still, it is not as important as aluminum, but you will require much of it, if you decide to develop your aviation. Partially, it is also used for production of cars, but local resources should be able to cover that demand.
Wolfram
This material is only obtainable through trade and local markets.
Construction | Demand |
Artillery | Medium |
Mechanized artillery | Medium |
Aviation | High |
Note: Nearly all types of artillery require wolfram, so you should focus on obtaining it, if you want to provide individual divisions with artillery. In the case of aviation, you require this material only for jets, but requirement of assembly lines here is 3 units, which is not too much.
Steel
This material is only obtainable through trade and local markets.
Construction | Demand |
Weaponry | High |
Gear for support battalions | Medium |
Cars | Low |
Mechanized vehicles | High |
Artillery | High |
Tanks | High |
Navy | High |
Note: High demand for steel should not be a surprise. It should be noted that steel is not required only for production of planes. You can notice increased demand for this material in all assembly lines. In the case of firearms, demand for this material grows with development of technology. As for the rest of the areas, this material is necessary at each production stage and if you do not have enough of that coming from your geographical situation, you will be devoting the most of your convoys to importing it.
Chromium
This material is only obtainable through trade and local markets..
Construction | Demand |
Navy | Medium |
Tanks | High |
Note: Chromium is especially important for production of armored vehicles. Regardless of the type, you will have to deal with increased demand. Additionally, some of the assembly lines of the navy also use chromium. Demand in this case is medium, because some of the units do not require chromium at all. Still, there are units that will have to import it in larger quantities.
