In many chemical plants, delivery capability depends not only on production capacity but also on inventory transparency. Where is each IBC located? How much product is left inside? When does a replenishment need to be made? Has the container been moved, shaken, or stored incorrectly? And how can safety, quality, and logistics processes be automated before bottlenecks arise?
Intermediate Bulk Containers, or IBCs for short, have long been more than just simple transport and storage containers in the chemical, specialty chemical, lubricant, paint and coatings, water treatment, and distribution industries. They are mobile inventory points in a complex supply chain. This is precisely why IoT sensors for IBCs are becoming a strategic tool: they provide digital visibility into fill levels, locations, consumption, and conditions.
But not every sensor technology is suitable for every chemical plant. Ultrasound, radar, weight sensors, pressure measurement, GPS tracking, NB-IoT, LTE-M, LoRaWAN, ATEX-certified hardware, ERP integration, and vendor-managed inventory each serve different purposes. Selecting just one sensor usually solves only a partial problem. In contrast, taking a holistic approach to IBC monitoring lays the foundation for automated reordering, better inventory planning, fewer emergency deliveries, and new digital service models.
This Cornerstone Guide explains which IoT technologies are relevant for IBCs, what chemical companies should consider when making their selection, and why modern smart IBC solutions today go far beyond mere level measurement.
Why Chemical Companies Should Monitor IBCs Digitally
Many companies know exactly how much material has left the plant. It’s much harder to determine how much product is currently still with the customer, in an off-site warehouse, in a consignment warehouse, or at a decentralized production site. This is precisely where typical problems arise:
A customer places a reorder too late. An IBC is empty, even though the ERP system still shows it as in stock. A container is in transit but cannot be located. A product is stored incorrectly. A field service team has to manually check inventory levels. The planning department bases its decisions on outdated consumption data. And in the worst-case scenario, this leads to production downtime, rush deliveries, or customer complaints.
IoT sensors for IBCs bridge this gap by turning the container into a digital data source. A passive container becomes a smart IBC that automatically transmits its fill level, location, and condition.
This offers clear advantages for chemical companies:
- Near-real-time transparency regarding IBC fill levels
- Automated reordering based on defined thresholds
- Fewer manual inventory checks
- Better planning of production, transportation, and scheduling
- Reduced safety stock
- Fewer express deliveries and emergency orders
- Greater customer loyalty through vendor-managed inventory
- Better traceability of containers and products
- Greater control over reusable IBC fleets
- New business models such as pay-per-use, consignment stock, or digital service contracts
In the chemical industry in particular, IBC monitoring is not just a matter of efficiency. It affects supply security, workplace safety, quality assurance, and the cost-effectiveness of entire supply chains.
What must an IoT sensor for IBCs really be capable of?
Many providers talk about “smart tanks,” “IBC tracking,” or “digital level measurement.” In practice, however, a single measurement parameter is rarely sufficient. A modern IBC sensor for chemical plants should not only know whether a container is full or empty; it should understand the entire context of its use.
Six capabilities are crucial:
1. Measure fill level
The foundation of every smart IBC solution is reliable level measurement. It answers the question: How much product is left in the IBC?
For chemical plants, it is crucial that the measurement functions reliably—even with different media, varying container types, movement, foaming, condensation, or difficult surfaces.
2. Detecting location
For decentralized customers, consignment warehouses, or reusable IBC fleets, level measurement alone is not enough. Companies need to know where a container is located: at the plant, at the customer’s site, in an off-site warehouse, in transit, or at the wrong location.
3. Monitor temperature
Many chemical products, additives, lubricants, food additives, or pharmaceutical intermediates are temperature-sensitive. Temperature data helps identify quality risks early on and better document storage conditions.
4. Tracking Movement and Impact
An IBC can be moved, transported, mishandled, or damaged. Motion sensors and shock detection provide important information for logistics, quality assurance, and complaint management.
5. Enabling automation
The real added value comes not from individual measurement values, but from processes: automatic reordering, consumption forecasts, inventory alerts, best-before-date logic, ERP interfaces, and digital workflows.
6. Easy to Retrofit
Chemical companies often operate existing IBC fleets. A good solution must therefore be retrofittable: quick to install, low-maintenance, robust, and deployable without complex infrastructure.
This is precisely where the market diverges. Many solutions can handle individual tasks well. The most powerful systems combine level, temperature, location, motion, shock detection, software, automation, and integration into a single, comprehensive solution.
A Comparison of the Most Important Sensor Technologies for IBCs
Radar Level Measurement: The Robust Solution for Demanding Chemical Applications
Radar is one of the most powerful technologies for non-contact level measurement in IBCs. The sensor emits electromagnetic signals and uses them to determine the distance to the product surface. The level is then calculated from this data.
The major advantage: Radar is non-contact, robust, and less susceptible to many sources of interference that can affect other measurement methods. This is particularly relevant for chemical plants because media often react differently: Some liquids foam, others form vapors, some have changing surfaces, or are stored at different temperatures.
Radar is particularly well-suited for:
- Chemicals and specialty chemicals
- Additives
- Lubricants
- Paints, coatings, and binders
- Solvents
- Cleaning chemicals
- Water treatment chemicals
- Hazardous substances, provided that the hardware and operating environment are appropriately certified
Modern Smart IBC solutions are therefore increasingly relying on radar. However, radar alone is no guarantee of good data. What matters most is how the raw measurement values are interpreted, filtered, and translated into usable level information. In real-world IBC fleets, it’s not just the hardware that matters, but above all the measurement logic behind it.
A solution like the Packwise Smart Cap combines 60-GHz radar with an evaluation algorithm specialized for IBC applications. This turns a single measurement point into a reliable basis for decision-making regarding inventory, consumption, replenishment, and planning.
In short: For many chemical plants, radar is the best foundational technology for digital IBC level measurement. But it only becomes truly powerful when combined with industry-specific data intelligence.
Ultrasonic Sensors: Simple, Non-Contact, but Not Always Stable Enough
Ultrasonic sensors also measure non-contact. They emit sound waves that are reflected by the liquid surface. From this, the distance—and thus the level—is calculated.
Ultrasonic technology can be attractive for simple applications, especially when the media are non-critical and environmental conditions remain stable. The technology is widely used, relatively easy to understand, and can be deployed in many tanks or vessels.
However, there are limitations for chemical plants. Ultrasonic sensors can be affected by foam, vapors, condensation, temperature differences, installation conditions, or turbulent surfaces. For simple media, this may be sufficient. However, with demanding chemical products, mobile IBCs, or automated replenishment processes, data quality can become a risk.
Ultrasonic technology is particularly suitable for:
- simple liquids
- stable storage conditions
- applications without high requirements for process automation
- Cases where rough level information is sufficient
For chemical plants that rely on precise IBC inventory data, automatic reordering, and reliable consumption forecasts, radar is often the more robust choice.
Weight sensors: Good for mass measurement, but less flexible in mobile applications
Weight sensors measure the weight of an IBC rather than its fill level. The contents can be calculated from this, provided the tare weight and product density are known.
The advantage: Weight measurement is unaffected by foam, vapor, or surface conditions. It can be particularly useful when mass, rather than volume, is the decisive factor.
The disadvantage: Weight-based sensor technology is often less flexible in mobile IBC management. It requires suitable weighing points, pallet solutions, or stationary installations. This can be costly for decentralized customer sites, rotating IBC fleets, or rapidly scaling rollouts.
Weight sensors are particularly suitable for:
- stationary storage locations
- defined weighing stations
- reliable tare and density data
- Applications where mass is more important than volume
For dynamic chemical logistics, vendor-managed inventory, and mobile IBC fleets, a smart cap mounted on the container is often significantly more practical.
Pressure sensors: Precise, but in contact with the medium
Pressure sensors measure the hydrostatic pressure at the bottom of a container. This data is used to calculate the fill level. While the technology can be precise, it has one major drawback: it often comes into contact with the medium.
In the chemical industry, contact with the medium can be problematic. Material compatibility, seals, cleanability, corrosion, contamination, and regulatory approvals must be carefully evaluated. For aggressive, sensitive, or frequently changing products, non-contact measurement is often the safer and lower-maintenance option.
Pressure sensors are particularly suitable for:
- stationary systems
- known media
- controlled process environments
- Applications with suitable media-contacting materials
For flexible IBC fleets in the field, retrofit capability is often limited.
GPS and asset tracking: Important, but without fill level data, they’re only part of the solution
Asset tracking answers the question: Where is my IBC? This is important for chemical plants, but it is not sufficient on its own. A location signal says nothing about whether a container is full, half-full, empty, damaged, or stored incorrectly.
Pure IBC tracking is therefore primarily relevant for logistics and container management:
- Where is the container located?
- Has the IBC been moved?
- Has the container left the warehouse?
- Is the IBC with the correct customer?
- Are there any losses in the reusable fleet?
- When can empty containers be picked up?
The greatest added value is achieved when tracking is combined with fill level measurement, temperature data, motion data, and software processes. It is precisely this combination that turns a tracker into a true Smart IBC solution.
The key question: Sensor or system?
Many companies start by asking, “What kind of IBC sensor do we need?” A more strategically sound question is:
What problem do we want to solve digitally?
Is it just a matter of occasionally checking the fill level of a single container? Or is the goal to automate an entire chemical supply chain?
For simple use cases, a single sensor may be sufficient. For industrial chemical companies with many customers, multiple locations, hazardous materials, returnable containers, consignment warehouses, or recurring consumption patterns, a system is required.
A high-performance IBC monitoring system consists of:
- robust sensor hardware
- contactless level measurement
- Temperature, motion, and shock detection
- Location data
- Cellular or LPWAN connectivity
- Battery life spanning several years
- ATEX options for hazardous areas
- Easy retrofitting
- Web dashboard and app
- ERP and REST API integration
- Automated alerts
- VMI and reorder logic
- Consumption forecasts
- Data history and reporting
Packwise follows precisely this system approach: The Smart Cap delivers data directly at the IBC, while Packwise Flow uses this data to generate inventory intelligence, VMI processes, best-before date logic, forecasts, and operational workflows. This means the solution goes far beyond traditional level sensors.
Where Packwise Smart Cap Excels
1. Radar Level Measurement for IBCs
The Packwise Smart Cap uses 60-GHz radar for contactless level measurement in IBCs. For chemical plants, this is a decisive advantage because no direct contact with the medium is required and the measurement is designed for mobile containers.
The difference lies not only in the radar itself. What’s crucial is the combination of sensor technology, real-time measurement data, and specialized analysis. The Smart Cap was developed specifically for IBC applications, not as a generic tank solution. This allows it to better address the typical challenges of mobile chemical containers.
2. Mobile Multi-Sensing Instead of a Single Measurement Value
Many solutions provide either fill level or location. The Packwise Smart Cap combines multiple data points in a single device:
- Fill level
- Temperature
- Location
- Motion
- Shock
This combination is particularly valuable for chemical plants. In practice, inventory, quality, and logistics are all interconnected. An almost empty container at a customer’s site has different implications than an almost empty container at our own plant. A full IBC subjected to shock can pose a quality risk. A temperature-sensitive product requires different processes than a non-temperature-sensitive raw material.
Multi-Sensing makes the IBC not only visible but also interpretable.
3. Packwise Flow: From Measurement Data to Automated Process
Level data is only valuable if it leads to decisions. Packwise Flow connects IBC data with operational workflows:
- digital inventory management
- automatic threshold alarms
- Vendor-Managed Inventory
- Best-Before Date (BBD) logic for shelf life and product age
- ML-powered consumption forecasts
- Replenishment planning
- Customer portals
- Scan App
- ERP and REST API integration
This transforms IBC Monitoring into a tool for supply chain automation. Chemical companies can proactively supply customers instead of waiting for orders. Planning and sales teams can identify consumption patterns early on. Production planning and logistics operate based on real-time data rather than manual feedback.
That’s the real leap: from sensor to digital inventory platform.
4. Retrofit and “Deploy & Forget”
A common reason why IoT projects fail is the complexity of implementation. Additional infrastructure, manual configuration, complicated installation, or high maintenance requirements slow down rollouts.
The Packwise Smart Cap is designed for easy retrofitting of existing IBC fleets. The goal: install, activate, use. This plug-and-play capability is crucial, especially for large fleets. A chemical plant does not have to retrofit every location to start using digital IBC monitoring.
5. Focus on ATEX and Chemical Applications
Chemical applications have different requirements than traditional asset-tracking projects. Explosion-hazard zones, hazardous substances, safety processes, quality documentation, and rugged hardware are key selection criteria.
Packwise is designed for industrial liquids and chemical-related applications. This is evident not only in the hardware but also in the use cases: chemicals, specialty chemicals, lubricants, paints and coatings, water treatment, distribution, pharmaceuticals, and food ingredients.
6. ERP Integration and Data Sovereignty
For chemical companies, an IoT solution is scalable only if it fits into existing system landscapes. Level data must be integrable into ERP, scheduling, customer portals, BI systems, or internal workflows.
Packwise supports this integration via REST API and ERP connectivity. This allows sensor data not only to be displayed but also to be directly incorporated into operational processes.
Typical Use Cases for IoT Sensors on IBCs
Vendor-Managed Inventory in the Chemical Industry
Vendor Managed Inventory, or VMI for short, is one of the strongest use cases for smart IBCs. The supplier assumes responsibility for the customer’s inventory and proactively restocks before materials run low.
Without IoT data, VMI often relies on estimates, manual reports, or regular inspection trips. With smart IBC data, VMI can be automated:
- The fill level is measured regularly.
- Consumption is tracked.
- Threshold levels trigger restocking processes.
- Forecasts indicate when a container will be empty.
- Customers enjoy supply reliability.
- Suppliers increase customer loyalty and predictability.
For chemical companies with recurring deliveries, VMI is a direct lever for revenue security and service quality.
Automatic reordering of chemicals
Many customers wait until the IBC is nearly empty before placing an order. This leads to rush deliveries, stress in scheduling, and unnecessary safety stock.
With IoT-based IBC monitoring, reordering can be automated. As soon as the level falls below a defined threshold, an alarm, an order recommendation, or an automated workflow can be triggered. In combination with consumption forecasts, the system not only identifies when a reorder is needed but also determines the optimal delivery time.
High-intent use cases here include:
- automatic chemical reordering
- digital consumption monitoring
- IBC residual quantity monitoring
- Replenishment planning for production chemicals
- Replenishment for specialty chemicals
- Automated scheduling for IBCs
Consignment Stock and Pay-per-Use
Many chemical companies provide goods to customers but do not bill until they are consumed. This requires reliable consumption data. IoT sensors on IBCs enable transparent inventory and consumption tracking.
This lays the foundation for:
- Consignment Stock
- Consumption-Based Billing
- Pay-per-use models
- Digital service contracts
- Transparent customer portals
- Less manual reconciliation
For suppliers of chemical products, this can be a real competitive advantage: The customer no longer has to place orders, take measurements, or submit reports. The supplier manages inventory as a digital service.
Empty Container and Reusable IBC Management
IBC fleets are expensive. If containers are lost, remain with the customer for too long, or aren’t returned on time, unnecessary costs arise.
Using location data, movement data, and fill-level information, empty container management can be significantly improved:
- Identify full IBCs in use
- Identify empty IBCs for pickup
- Reduce downtime at the customer’s site
- Prevent losses
- Increase turnover rate
- Plan fleet requirements more effectively
- Digitize deposit and return processes
The difference between simple tracking and Smart IBC Monitoring is crucial here: A location alone does not indicate whether a container can be picked up. It is the combination of location and fill level that makes the process intelligent.
Quality and Temperature Monitoring
In many industries, it’s not just the quantity that matters, but also the condition of the product. Temperature data, shock events, and movement history can provide indications of quality risks.
Typical Applications:
- Temperature monitoring of sensitive liquids
- Alarm for excessively high or low temperatures
- Verification of storage conditions
- Shock alarm for transport damage
- Support for complaint investigations
- Best-by-date and shelf-life logic
The combination of fill level and status data can create significant added value, particularly for specialty chemicals, pharmaceutical intermediates, food ingredients, additives, and high-value liquids.
Which wireless technology is best suited for IBC monitoring?
NB-IoT and LTE-M
NB-IoT and LTE-M are particularly attractive for many industrial IoT applications. They utilize cellular networks, are energy-efficient, and are well-suited for small data sets such as fill level, temperature, location, or status reports.
For chemical companies with distributed customer sites, these technologies are often attractive because there is no need to set up a proprietary gateway infrastructure.
LoRaWAN
LoRaWAN is particularly well-suited for factory premises, warehouses, or locations where dedicated gateways can be operated. The technology is energy-efficient and well-suited for regular sensor data. However, for widely dispersed customer sites, the infrastructure can become a limiting factor.
Mobile Network-Based Solutions
Traditional cellular connectivity can be useful where higher availability, more frequent data transmission, or international coverage is required. However, energy consumption and the cost structure should be taken into account.
Satellite
Satellite connectivity can be a viable option for very remote locations. For many chemical plants, however, it is not the first choice but rather a supplement for specific remote applications.
What Really Matters
The best connectivity is the one that fits the application profile. An IBC at your own plant has different requirements than an IBC at a customer’s site, on a farm, at a water treatment plant, or along an international transport route.
For most Smart IBC projects, these questions are more important than the wireless standard itself:
- Where are the IBCs located?
- How often does data need to be transmitted?
- Is there network coverage?
- How long should the battery last?
- Does data need to be transmitted indoors or outdoors?
- Are the IBCs stationary or mobile?
- Which countries and customer locations need to be covered?
A good solution abstracts this complexity for the user. Chemical plants don’t want to manage wireless technology. They want reliable inventory data.
ATEX, Retrofit, and Safety: Especially Important in the Chemical Industry
In chemical plants, potentially explosive atmospheres, corrosive substances, or special safety requirements may be relevant. Therefore, IoT sensors for IBCs should be evaluated not only based on their range of functions but also on their industrial suitability.
Key considerations include:
- Is the hardware suitable for the intended environment?
- Are there ATEX options for hazardous areas?
- Is the measurement contactless?
- Does the sensor need to come into contact with the medium?
- Can it be installed non-invasively?
- How is the battery replaced or maintained?
- How robust is the housing?
- Does the solution work with mobile IBCs?
- Is there any experience with chemical applications?
This is precisely where it becomes clear whether a solution was built for industrial chemical processes or rather originates from the general asset tracking market.
Selection Matrix: Which IoT technology is right for which chemical plant?
Application 1: Monitoring IBC fill levels at your own plant
If IBCs are primarily located at the company’s own plant, warehouse, or production facility, reliable level measurement is crucial. Location data is less important, while temperature and movement may be relevant depending on the product.
Recommended Solution: Radar-based level measurement with a digital dashboard
Key considerations: measurement stability, easy installation, battery life, integration into existing processes
Application 2: Automatically replenishing customer inventory
When products are delivered to customers on a regular basis and the supplier wants to manage inventory, more than just level data is needed. Key factors include consumption trends, thresholds, forecasts, reorder logic, and the customer’s perspective.
Recommended Solution: Smart IBC with radar, location data, Packwise Flow, VMI logic, and ERP integration
Particularly important: automation, consumption forecasting, customer portal, and reliable data quality
Application 3: Managing a reusable IBC fleet
For large IBC fleets, the focus is on turnaround times, empty containers, location transparency, and loss prevention. Here, the combination of location, movement, and fill level is crucial.
Recommended Solution: IBC tracking plus fill-level sensors in a single device
Particularly important: location data, movement data, empty container detection, fleet overview
Application 4: Monitoring hazardous materials and hazardous areas
When IBCs are used with hazardous substances or in potentially explosive atmospheres, safety requirements must be assessed early on.
Recommended Solution: Retrofit-capable, non-contact sensors suitable for the application, with an ATEX option
Particularly important: certification, non-contact measurement, rugged hardware, and experience with specific chemicals
Application 5: Documenting Quality and Shelf Life
For sensitive products, temperature, motion, shock, and shelf life are critical factors. Simple level measurement alone is not sufficient.
Recommended Solution: Multi-sensing solution with temperature, shock, motion, and best-before date (BBD) logic
Particularly important: data history, alarms, quality documentation, and customer approval processes
Why the best solution doesn’t just measure—it makes decisions
A single sensor answers a single question. An intelligent IBC system answers several:
- How much is left in the container?
- Where is the container located?
- When will it be empty?
- Do we need to reorder?
- Was the IBC moved?
- Was there a shock event?
- Is the product still within its shelf life?
- Which customer needs a restock next?
- Which delivery routes can be combined?
- Which IBCs can be picked up?
- Which inventory levels are critical?
For modern chemical companies, this decision-making capability is crucial. IBC monitoring is not an isolated IoT project, but rather a building block for a digital supply chain, automated scheduling, and customer-centric service models.
Packwise Smart Cap and Packwise Flow are particularly powerful because they combine hardware, sensors, software, and process logic. The Smart Cap captures the relevant data directly from the IBC. Packwise Flow transforms this data into actionable insights for inventory management, VMI, best-before dates, ML forecasting, and operational workflows.

Frequently Asked Questions About IoT Sensors for IBCs
What is an IoT sensor for IBCs?
An IoT sensor for IBCs is a connected device that collects data such as fill level, location, temperature, movement, or impact directly from the intermediate bulk container and transmits it digitally. This enables chemical companies to automatically monitor inventory, consumption, and container movements.
Which technology is best suited for IBC level measurement?
Radar is particularly well-suited for many industrial chemical applications because it measures without contact and can withstand harsh conditions. Ultrasonic technology may be sufficient for simple applications, but it is more dependent on environmental conditions. Weight and pressure sensors are suitable for specialized or stationary applications.
What is a Smart IBC?
A Smart IBC is an IBC that uses sensors and connectivity to provide digital data. This includes fill level, location, temperature, movement, impact, and consumption information. When combined with software, this data can enable automatic reordering, VMI, empty container management, and consumption forecasts.
Why isn’t fill level alone enough?
Fill level only shows how much product is in the container. Additional information is important for operational decisions: Where is the IBC located? How quickly is it being consumed? Has it been moved? Were there any temperature deviations? Is a replenishment needed? That’s why multi-sensing and software are crucial.
How does IoT support vendor-managed inventory in the chemical industry?
IoT sensors provide consumption and fill level data at the customer’s site. This enables the supplier to proactively plan restocking, define thresholds, forecast consumption, and automate orders. This reduces bottlenecks, manual coordination, and emergency deliveries.
Can IoT sensors be retrofitted to existing IBCs?
Yes, modern solutions are retrofit-compatible. A Smart Cap can be retrofitted to existing IBCs without replacing the entire container. For chemical companies, this capability is crucial because it allows existing fleets to be digitized quickly.
What role does ATEX play in IBC sensor technology?
When IBCs are used in potentially explosive atmospheres, the sensor technology must be suitable for the specific zone and application. Chemical plants should assess ATEX requirements early on and use only solutions that are appropriate for the operating environment.
How long does the battery in an IBC sensor last?
Battery life depends on the measurement interval, transmission interval, wireless technology, site conditions, and sensor technology. For industrial IBC solutions, battery life spanning several years is important to ensure that rollouts remain cost-effective and require minimal maintenance.
Can IBC Monitoring be integrated into ERP?
Yes, high-performance solutions offer API and ERP integrations. This allows fill level data, consumption values, alarms, and reorder information to be transmitted directly to existing systems.
For which industries is Smart IBC Monitoring suitable?
Smart IBC Monitoring is particularly well-suited for the chemical, specialty chemical, lubricants, paints and coatings, water treatment, food and beverage, pharmaceutical, agricultural, logistics, and distribution industries, as well as all companies that handle liquid products in mobile containers.
Conclusion: Choosing the right IBC sensor technology is not just a matter of technology
Anyone looking to digitize IBCs should not simply choose between radar, ultrasound, weight, or tracking. The key factor is which business problem needs to be solved: measuring fill levels, automating inventory, proactively supplying customers, ensuring quality, managing returnable containers, or developing new service models.
For simple applications, a single sensor may suffice. However, for chemical companies with decentralized customers, mobile IBC fleets, and recurring consumption patterns, more is needed: reliable level measurement, multi-sensing, long battery life, easy retrofitting, ATEX compliance, software logic, ERP integration, and automated processes.
This is precisely where the difference between a measuring device and a Smart IBC platform becomes apparent.
The Packwise Smart Cap combines 60-GHz radar level measurement with temperature, location, motion, and shock data. Packwise Flow uses this data for inventory management, vendor-managed inventory, best-before-date logic, machine learning-based forecasts, and integrable workflows. This transforms the IBC from an analog container into a digital inventory point in your supply chain.
For chemical companies, this means: less flying blind, fewer manual checks, fewer emergency deliveries—and significantly more control over inventory, customer supply, and container fleets.
Make your IBC fleet visible
With Packwise Smart Cap and Packwise Flow, you can digitize fill levels, locations, consumption, and replenishment processes directly at the IBC. This allows you to identify early on when customers need replenishment, which containers have been moved, and where inventory levels are becoming critical.
Digitally monitoring your IBC fleet lays the foundation for more efficient chemical logistics, automated reordering, better customer service, and data-driven decisions in the supply chain.
