This guide is intended to explain the Industries and industrial supply chain. The later part of the guide is covering Industries DLC content and will not be relevant for players who do not have it. The guide is supposed to cover all the important game mechanics, general tips/good practices, troubleshooting and some mod recommendations. I have not included traffic details or road/rail layouts as it is a huge topic on its own. Lastly, the guide is not supposed to be a walkthrough for a brutally efficient industrial supply chain. It is to help players explore on their own and be creative.
 
 

Industry Overview: Importance

Industries are a critical part of any city. In Cities Skylines, they serve two key purposes. Provide jobs and provide goods to be sold at commercial places.
 
 
The main alternative for jobs is offices, but they only take educated workers. Other alternatives like commercial or jobs at services are not enough for the entire population. You can import goods, but it has limits and needs extensive traffic management.
 
 
Tip: There are two other ways of providing goods. ‘IT specialization’ for offices manufacture invisible goods that don’t have any truck traffic and ‘organic and local produce’ district specialization for commercial make half of their goods themselves.
 
 
 

Industrial Supply Chain

There are 4 basic natural resources in Cities skylines. Oil, Ore, Fertile land and Forestry.
 
Oil and Ore are not renewable, and they deplete as they are used. (You can use the inbuilt mod to turn off depleting). Fertile land and forestry are renewable and do not deplete. However, if you plant a lot of trees on fertile land, you’ll lose land fertility. Forestry is just a bunch of trees; you can plant some and the game will treat at natural resource. If you remove them, natural resources will go away. It is not very realistic or logical, but it is what it is.
 
 
Extractor buildings take the natural resources and turn them into raw materials. They need to be on the land where natural resources are present.
 
 
Processor buildings process the raw materials and turn them into processed materials.
 
 
Processed materials from all 4 industry types are used by a single type of generic industry to produce goods that are sold by commercial places.

Tip: Recycling centre turns garbage into processed materials that can be used by generic industries.
 
 
 

Industrial Zoning and District Specializations

Extractors, Processors and Generic industries all grow on industrial zones. By default, generic industries will grow on your industrial zones and just import Processed Materials if you don’t have industry specialization.
 
 
If you make a district and give it one of the specializations, it will only grow extractors and processors based on natural resources availability on the zoned land.

Because all the materials I mentioned so far can be imported or exported, You are not forced to balance them. However, you can use districts and specializations to reduce imports and control your traffic flow.
 
 
Confusing names: both raw materials and processed materials of a particular industry type are labelled the same on trucks and import-export UI. This can be confusing at times. So, keep it in mind.
 
 
This is my city’s farming specialized industry importing a lot of agricultural products(crops) and exporting a lot of agricultural products(processed material).

Industries DLC: Make your own profit!

The flagship feature of the DLC is the ability to build and operate your own industrial buildings, including extractors, processors, factories and warehouses. These buildings are huge and look great.
 
 
You own these industries, so you will get profits instead of taxes. On the flip side, if there are problems with the operation and supply chains, you will get losses instead of abandoned buildings. You will need to manage the supply chain much more carefully and warehouses will help you do that.
 
 
 

Materials and Supply Chain Overview

Before we start, here’s the complete supply chain and material list, including DLC, for your reference. We will go through it all.

This is the table for all the materials available in the industrial supply chain.

This is the supply chain flowchart from the wiki. The names are slightly different.
 
 
 

Industrial Areas: New Supply Chains

To start up with your own industrial area, you need to first draw your own industry area and put the main building.
 
 
Cities: Skylines Useful Techniques for Industries and Supply Chain - Industrial Areas: New Supply Chains - 5F69CD3
 
 
You will start with a few buildings unlocked, but as you get more workers and produce more, your areas will level up and unlock more buildings. You also have access to some policies, auxiliary buildings and bonuses based on the industry area level. They are quite self-explanatory. You will also have storage buildings for raw materials, which we will discuss with warehouses.
 
 
Your DLC extractors will need to be placed on natural resources and you can see how much raw materials they will produce while placing. The raw materials from DLC extractors are named properly now; Oil, Ore, Crops and Raw forest products. They are functionally the same as raw materials produced by zoned extractors and completely interchangeable.
 
 
In a logical world, this should resolve the naming problem we saw earlier. But paradox decided to stay true to their name and now you’ll see your DLC farming extractor, which is meant to produce crops, send ‘agricultural product’ to a zoned processor, which will be processed to make ‘agricultural products’ again.
 
 
You can see my crops storage accepting ‘agricultural product’ and my crop farm sending ‘agricultural product’.

Your DLC processors use the raw materials to make newly introduced special goods. You have eight of them, two per industry type. They cannot be imported, and they do not have any substitutes. They are primarily used by unique factories, but generic zoned industries can also use them to make commercial goods.

Unique Factories: Truly Colossal!

These are some of the most gigantic and unique looking buildings in the game. They take some combination of the eight special goods as input material and produce unique factory goods which act like commercial goods.
 
 

  • All unique factories goods are functionally the same despite different names (like electronics, cars) shown on the building info view.
  • Unique factories do not belong to any particular industry type, and consequently can be placed anywhere on the map.
  • They need multiple input materials, so they will stop working even if just one of them is missing. But, they can make a huge amount of profit if your supply chains are functioning properly.
  • You can also control their production rate between 50% to 150%. The operating cost is proportional to the production rate.
  • Apart from special goods, some unique factories will ask for crops directly.
  • Shipyard makes huge ships. So, they do not need trucks to send to customers. Customers just sail their ships away.

 
 
 

Managing Supply Chain:

Supply

 
 
The first part of managing the supply chain is ensuring you have enough supply. This is not exactly a confusing task because the exact input/output numbers for all DLC buildings are known. Just look out for productivity bonuses and multipliers.
 
 
The wiki has all the production rates, costs, multipliers and other numbers. – [paradoxwikis.com] 
 
 
The raw materials and special goods can be used by zoned industries. This means if your supply chain is very lean and zoned industries poach your materials, you will face problems. Keep redundancies at each step of your supply chain to ensure your unique factories do not run out of input materials.
 
 

For example, if your unique factory needs 100 tons of special goods, make 110 tons of them. To make 110 tons of special goods, you might want to make 120 tons of raw material. The exact production buffer needed is unique to your situation, so play around a bit.

 
 

Transportation:

 
 
The second and more challenging part of the supply chain is transportation. There can be an entire guide on this topic. Traffic is an obvious suspect; but even with good traffic, you can end up having a lot of problems with no obvious solution. I will explain the fundamental game mechanics and why they cause problems.
 
 

The core problem in industries DLC is that buildings do not care about the distance when they buy input material or sell output material.

 
 
This is unrealistic and coupled with the following game mechanics they cause a lot of headaches.
 

  • Buildings have a limited number of trucks.
     
     
     
     
     
    All the buildings and warehouses in the industrial supply chain have trucks that they only use to sell. They will never send their own trucks to bring anything. If buildings keep selling to distant places including exporting out of town, they will run out of trucks. Soon, they will run out of internal storage to keep output material as well. In this case, they will stop working and throw a misleading ‘not enough buyers’ error.
     
     
     
     
     
    Tip: Always check the number of trucks being used when you see this error. If all the trucks are being used, then you are running out of trucks. If the number is flickering, they have trouble finding a path to their destination, check the road networks, especially one-ways.
  • Buildings order quite late and only once.
     
     
     
     
     
    They expect very quick delivery. If they had ordered from a nearby place, it would be okay. But these people expect next day delivery even if they had ordered from another galaxy. You will often find buildings that bought from across the city or outside map and refuse to reorder when the truck is stuck in transit. Soon, they will run out of raw materials, complain about it and stop working.
  • Fun happens when these two problems coincide. A building will order from someone who does not have any truck available. One building will complain ‘not enough buyers’ and another will complain ‘not enough raw materials’. More often than not, they’re right next to each other…

 
So, what’s the solution? Warehouses!!
 
 
 

Warehouses

Industries DLC introduces many options for storing all kinds of materials. They have their own fleet of trucks and can act as a large buffer because of their much larger storage capacity. Using them properly requires a bit of thought. Let’s see how they function.
 
 
All 4 types of raw materials have their own special storage facilities that can not be utilized for any other material. They are found in specific industry tab. All processed materials and goods are stored in general storage facilities.
 
 
Warehouses will solve the problem of limited trucks. But, they can not do anything if your buildings decide to ignore a full warehouse nearby and order from another side of the map. Unique factories are especially notorious for this. Spread out industrial areas will keep cross ordering across the city and cause problems. The only vanilla solution for this problem is to place everything nearby or hope your industries get lucky when they order randomly.
 
 

Accounting problem:

 
 
Apparently, all your buildings buy goods for free from your other buildings. That means the last building in the supply chain will claim all the profits. Consequently, your industrial areas will always make a loss if they send most of the materials to unique factories or warehouses. Unique industries will always get all the processed materials for free since those cannot be imported or made by zoned industries. This is why your budget panel does not reflect the actual performance of the industries.
 
 
Also, the industrial cash flow number and production number in the industrial overview window will fluctuate quite a bit because the profit is only registered when the trucks drop off materials or goods to someone else.
 
 
Here’s an example of my city attributing most of the profits to my unique industries and warehouses. (Ignore fishing, it is part of sunset harbor DLC, not industries DLC.)

Warehouse Modes

Warehouses operate in three modes and they are ALWAYS happy to buy and sell to industrial buildings.
 
 

  1. Empty

     
     
     
     
     
    In this mode, the warehouse aggressively tries to sell off everything. This means it will sell to other warehouses as well as export. This mode is suitable for materials that you do not need for input nearby. This mode ends up using a lot of trucks and you might want to have multiple small warehouses instead of one large one to increase truck count.
     
     
     
     
     
    If a warehouse on empty mode is consistently using all the trucks and still not able to decrease inventory level, you should consider having another warehouse nearby on empty mode.
     
     
     
     
     
    A warehouse on the empty mode will not stop accepting material from the industrial buildings. It will just try to sell it off afterwards.

  2. Fill

     
     
     
     
     
    In this mode, the warehouse aggressively tries to buy material and stay at 100% inventory level. It will buy from other warehouses/industries and import if possible. This is suitable for material that you need as input for nearby industries and you are not producing it in the vicinity. Because trucks are only used for selling, a warehouse in fill mode is unlikely to use up all the trucks, so you can start with a smaller warehouse.
     
     
     
     
     
    If the inventory level is consistently low, it is a sign that you are running out of material. Either you have too much demand and you need more storage capacity, or your supply is struggling and you need to increase it.
     
     
     
     
     
    A warehouse on fill mode will not stop selling material to the industry. It will just try to buy more afterwards.

  3. Balanced

     
     
     
     
     
    The balanced mode is a mixture of fill and empty mode. Above 75% inventory level, the warehouse will try to actively sell like it is on empty mode. Below 50%, it will try to actively buy things like it is on fill mode. Between 50% and 75%, it will act passively. It will neither import nor export, just buy if someone needs to sell and sell if someone needs to buy.
     
     
     
     
     
    This mode is suitable for a material that you are producing and using nearby. You can probably get away with keeping all the warehouses in the balanced mode because the behaviour is dynamic.
     
     
     
     
     
    Ideally, you should have slightly more supply than demand. In such case, your warehouse on balanced mode, acting as a buffer between nearby supply and demand buildings should sit slightly below 75% inventory level and have 3 or more trucks available. When your warehouse gets more than 75% level, the warehouse is able to sell off locally or export the extra supply and still have a few trucks in reserve for local delivery.
     
     
     
     
     
    If a balanced mode warehouse is consistently staying above 75% level and running out of trucks, it indicates that you have too much local supply and you do not have enough trucks to sell it. You should place more warehouses or upgrade to increase truck count. Of course, you can also make more demand buildings nearby since you have the supply.
     
     
     
     
     
    If the warehouse is consistently sitting well below 50%, it indicates that demand is high and your supply might be struggling. Check the supply and consider putting more warehouses.

 
 
 

Cargo Transportation Options and Traffic Tips

You are not limited to trucks and roads when it comes to cargo transfer in Cities Skylines. You can use cargo trains, ships and airplanes. Using them properly can help you massively. They can reduce the number of trucks needed because trucks only need to drop off locally.
 
 
Trains are easiest to use, but without mods, you might be plagued with almost empty cargo trains going around the city jamming your network. Making a functional train network requires some work, but it can be very rewarding.
 
 
Cargo ships and Airplanes do not suffer from traffic since they just phase through each other. But, placing them is tougher. Cargo harbours need access to shipping paths and Airports take a lot of space.

Traffic tips:

  • Avoid placing industrial buildings or warehouses directly facing the road. Make a dead-end alley for the entrance. This will ensure the trucks can come and go from either direction and they do not stop other vehicles when they are loading/unloading.
     
     
     
    Just make sure there’s no traffic light at all the alleys. It is okay if an alley has 4-5 buildings on it, but do not make it very long.

  • Avoid excessive one-ways in the Industrial areas because they can cause complications. Very dense industrial areas will also cause traffic issues.
  • Cargo stations, harbours and airports can end up causing a lot of road traffic at the entrance because they have an inherent limit of how fast they can absorb the trucks. Use dedicated one-way roads for these buildings instead of putting them directly on main roads. If there are significant backlogs near the entrance, make another building instead of creating very long buffers.
  • Rail network is shared between passenger and cargo trains and they can interfere with each other. You should try to make sure that all your stations have a bypass that is shorter, so other trains actually prefer to use it. You might need to separate cargo and passenger traffic by building multiple rail networks.
  • You can disable intercity train traffic on passenger train stations. Allowing intercity traffic on only a few passenger stations can free up the rail network significantly.
  • The edge of the map absorbs trains at a rather slow rate, so you might need to rely on mods to help you there. Ships and planes do not suffer from such issues.

 
 
 

Recommended Mods

These are some mods that can help you better enjoy industries DLC without worrying about buggy behaviour and idiosyncrasies. The mods mentioned here offer many functionalities, but I am only mentioning the main reason I included them in the list. I have not included quintessential road traffic mods like TMPE or road anarchy.
 
 

  • Extra Landscaping Tools – Allows you to put natural resources like oil, ore and fertile land wherever you want.
  • Extended Game Options – Allows you to change the depletion rate of oil and ore.
  • More Effective Transfer Manager – Fixes a lot of supply chain issues by improving buy/sell algorithms for all services by using the geographical distance between buildings. It also has a few great options for warehouses and export. It is a plug-n-play mod and I always use it.
  • Enhanced District Service – It is an extremely powerful mod that allows you to micromanage all the buy/sell relations for industries and services. It is a lot of work though.
  • Industries Rebalanced – Changes a lot of numbers like production rate and truck’s cargo capacity for industries DLC buildings to make them more realistic.
  • Optimized Outside Connections – Allows your trains, ships and planes to wait for cargo before moving, effectively reducing the number of them on the network.
  • More Network Stuff – Allows you to make custom ship path, so you can place harbour more easily.
  • Upgrade Untouchable: Convert stations – Allows you to edit roads connected to cargo harbours, You should consider using one-way roads with it.

 
 
 

Ending thoughts

Industries DLC can be a lot of fun and there is no one right way to build and manage. The knowledge here is a collection of my own experience, experiments and years of interaction with the community. I hope this guide helps you understand the game mechanics and allows you to be creative in your own city. Any feedback, suggestion and discussion are always welcome.
