As an industry that generates trillions of dollars in sales and employs millions globally, the chemical industry is ubiquitous when it comes to products and technology. Adapting to the ever-increasing competition, ever-evolving regulatory environment, and ever-changing customer needs has become an obvious challenge for any chemical enterprise. No matter how established a chemical company is, a well-organized inventory tracking system is irreplaceable for its success.

A leading player in the global chemical industry that has operations in 36 countries and produces 6 varieties of chemicals recently transformed its inventory tracking operations into a digital monitoring system to keep up. Let us have a look at their transformation story.

Challenges with Inventory Tracking in Chemical Industry

The Challenges They Faced

This chemical company was using returnable containers in the form of ISO and tonner tanks to safely store and transport liquid and gaseous chemicals to their customers. This meant that they endured a reverse logistics operation of the returnable assets from their customer and distributor sites around the world back to their factories, giving rise to the following challenges:

Challenge #1

Lack of Control over Tank Inventory

The company had 23,000 assets to monitor spread across 210 customer facilities. They had a large number of tonner tanks in their database, but they did not know their exact locations. Once a tank was delivered, they had several distributors that distributed them in specific areas. Therefore, they had no idea whether a tank would be lying in their facility, in a customer's facility, or with a consultant/distributor. Additionally, tanks were getting unintentionally exchanged with other chemical company's chemical tanks at the client location which were not always of the same quality as theirs. This forced them to buy new high-quality tanks every time a tank was exchanged, which increased capital expenditure.

Challenge #2

Inability to Orchestrate Dispatches/Retrievals Efficiently

Within their own locations, there were multiple processes (like the biennial audit of tanks), during which, the tanks could not be sent to the clients. This forced them to manually reconcile the data while dispatching. Since the data based on which tanks were to be dispatched was prepared by the supply chain (SC) department, the loading department had to capture data manually in the loading area, which was then given back to the SC department, who would pick up the tanks and send them back to the loading department. This created data voids within departments affecting effective collaboration and orchestration.

Challenge #3

Manual Logistics Data Entry

When the loading department received a list of tank inventory that they had to load onto trucks, they had no idea where the tanks were because they did not know the exact location within the warehouse. They had over 2,000 filled tanks at their facility at any point in time. So, every time a truck docked for loading, they had to manually search for the tanks listed in the invoice within a large warehouse or yard to load onto the truck.

Challenge #4

Incomplete Tank Data

Since the empty and filled tank locations were placed nearby, a filled tank often found itself mistakenly stored in the empty tank location. There was no way to keep track of the empty/full status of tanks lying at customer locations. This increased the probability of more tanks getting stuck at customer locations, which caused dispatch delays, disruption of manufacturing processes, and poor customer experience. It was also causing overstocking of tanks, which locked up their working capital. They needed a system to know the tank status — whether it was empty/filled — apart from the tank’s location at customer locations.

Challenge #5

Underutilization of Vehicle Capacity

Without proper data about the location of tanks, trucks were not being used to their maximum capacity. For instance, when a truck went to pick up empty tanks from one customer, and they had only two empty tanks, the truck would only carry two tanks from a customer location to their own facility although it had the capacity to backhaul more from another customer location nearby.

These challenges led to a labor-intensive, inefficient supply chain operation around the management of tank inventory.

They Evaluated RFID to Solve It, But to No Avail

The chemical company tried solving it using RFID (Radio Frequency Identification) tags, which involved automatic scanning of the tonner tanks. The problem with RFID however was the extensive infrastructure it required and the lack of accuracy. The heavy infrastructure requirements of RFID in the form of readers, antennas, LAN, and Wi-Fi further limited its use outside their own facilities. Moreover, installing this infrastructure across 210 customer facilities even without accounting for the maintenance aspect, would have taken years.

Therefore, they started looking for innovative solutions and visibility experts to implement a reliable inventory monitoring system, and that’s when Roambee came into the picture.

And Then Roambee Brought in the Right Solution

Roambee came in as a complete package from sensors to data actionability, enabling them to save time and effort in managing their returnable asset inventory better. It offered them solutions to the problems they were looking to fix for years.

Solutions to inventory tracking challenges in chemical industy


Solution #1

Better Inventory Management with Real-time Sensors

With Roambee’s inventory tracking system using infrastructure-less options like its BeeTrac or using its BeeBeacon-based Bluetooth Low Energy (BLE) technology, they were able to get real-time location data without any of the hassles of RFID installations. They were able to physically locate the tonner tanks that were in their database and manage their inventory better across their own and customer locations with ease.

Estimated Impact: RFID would have cost them $3,000 per location to install while Roambee did it at a fraction of the cost due to its infrastructure-light and infrastructure-less technology options. Further, installation and maintenance-related site visits across the 210 customer locations were eliminated.

Solution #2

Real-time Dispatch/Retrieval Inventory Lists

Real-time location of the inventory at their own facility and at their customer locations, without relying on anyone for scanning, allowed this chemical giant to manage large volumes of dispatches and retrievals effectively. Knowing the location of empty and full tanks at an overall site-level enabled them to reduce loading times.

Estimated Impact: Person hours & detention reduced significantly due to 0 instances of searching for stock prior to loading.

Solution #3

Automatic Data Capture and Dispatch Analytics

With real-time location and inventory lists, they could now segregate the tanks that were due for quality checks in advance and make sure that these specific ones were not dispatched to a client location. With Roambee data they know when the last filling was done and which tanks cleared the 48-hour monitoring period, simplifying long and convoluted processes.

Estimated Impact: During the first 3 months of the implementation, there were no instances of inventory mix-ups.

Solution #4

Real-time Tank Fill Status Alerts

Roambee’s real-time location and condition sensing data enabled the estimation of tank status changes automatically even at customer locations, and if a filled tank was still in the empty tank storage area, the system flagged it. These timely warnings not only helped reduce delays in dispatch but also helped eliminate possible hazards.

Further, the new inventory tracking system helped create a process where the chemical company could automatically get a list of all the tanks with quality checks upcoming within the next 6 months, and their real-time locations so they can keep an eye on tanks that are not quality-checked yet. When a tank is to be transported, the rule is to have it filled 48 hours in monitoring so that you are aware if there is any leakage or chance of leakage.

Estimated Impact: Regular dispatch delays had a direct cost impact, which the new solution eliminated. It also helped optimize tank inventory, saving thousands of dollars in working capital. Additionally, they could potentially suffer customer dissatisfaction and brand impact which one cannot place a cost on.

Solution #5

Real-time Dashboards to Optimize Vehicle Utilization

Roambee's data and dashboards enabled them to check if there were empty tanks with other customers at nearby facilities that could be picked and loaded in the remaining space available on a truck. This helped optimize truck capacity utilization and save trips.

Estimated Impact: Even a 10% improvement in truck utilization reduces your transport cost significantly when you are spending millions of dollars in just transport fees.

The Strategic Impact on Business

With Roambee’s tank inventory monitoring solution, the chemical company was not only able to save manual scanning time and eliminate human errors, but they also digitalized their tonner & tank management with real-time inventory locations, empty/filled tank alerts, automatic data capture, and useful analytics.

The solution transformed the way this chemical giant dealt with its inventory, helping them make more informed and confident decisions.

Many chemical enterprises are now realizing the increasing importance of digitalizing their inventory monitoring systems and focusing on better, more accurate, and easily accessible data. This is just the beginning of the transformation of the chemical industry using infrastructure-light or infrastructure-free visibility technologies.

The smart move to stay competitive is to join the digitalization brigade early and be proactive in reducing costs and errors that could cost you big!
