Container management: efficiently manage load carriers, inventories and flows.

Pallets, grid boxes, small load carriers and special containers are an essential part of many production and logistics processes. If suitable containers are missing at the right location, materials cannot be prepared, production orders cannot be supplied, or finished goods cannot be delivered.

At the same time, load carriers are often distributed across plants, warehouses, suppliers, customers and logistics service providers. Without a structured container management, it remains unclear how many containers exist, where they are located, who last received them and when their return can be expected.

The consequences can include overages, bottlenecks, long cycle times, additional coordination effort and unnecessary new purchases. This becomes especially problematic when different locations and business partners use their own spreadsheets, paper vouchers or separate systems.

A systematic container management therefore links inventory management, movement data, container accounts, return, disposition, maintenance and cost control. Barcode, RFID and mobile data capture can support data collection. An ERP system additionally provides the link to purchasing, goods receipt, warehousing, production, shipping, customers and suppliers.

What is container management?

Container management encompasses the planning, control, monitoring and optimization of load carriers and their movements.

The goal is to make suitable containers in the required quantity available at the right time and in the right place. At the same time, inventories, turnover times, losses and process effort should remain economically manageable.

Container management does not only consider the physical container. It also includes the associated information and processes:

• Container type and container properties
• Owner
• current location
• stock by site or partner
• incoming and outgoing movements
• loading status
• container account
• turnover and dwell time
• return
• cleaning
• inspection
• repair
• locking
• disposal
• costs and values

Depending on the company, the terms Ladungsträgermanagement, Lademittelmanagement, Leergutmanagement, Packmittelmanagement or Palettenmanagement are also used.

The terms overlap significantly. However, their concrete scope can differ. For example, pallet management often covers a narrower sub-area than company-wide container management with different load carrier types.

What are load carriers?

Load carriers are aids used to group, protect, store or transport goods, materials and components.

Typical load carriers include:

• Euro pallets
• one-way pallets
• plastic pallets
• grid boxes
• small load carriers
• large load carriers
• reusable crates
• trays
• racks
• Racks
• container
• barrels
• IBC containers
• rolling containers
• swap bodies
• special load carriers

Which load carriers are suitable depends, among other things, on the product, weight, dimensions, sensitivity, transport route, degree of automation and the requirements of the respective customer.

Transport containers

Transport containers protect and bundle goods during internal or external transport.

Storage containers

Storage containers are used for orderly and space-saving storage of materials, parts or products.

Small load carriers

Small load carriers are often used for smaller parts and components. Standardized dimensions can support storage, conveying technology and automated handling.

Large load carriers

Large load carriers are suitable for larger or heavier components and can be realized, for example, as grid boxes, large containers or special transport frames.

Special load carriers

Special load carriers are developed for specific products or processes. They can secure components, protect surfaces or enable a defined positioning.

Disposable and reusable containers: how to differentiate

For container management, the distinction between disposable (one-way) and reusable containers is particularly important.

One-way containers

One-way containers are typically not returned to the original cycle after use.

For their management, the following questions are particularly relevant:

• What is the current stock level?
• What quantities will be required in the future?
• When must replenishment be ordered?
• What lead time applies?
• What consumption is generated per product or order?
• How are disposal and recycling organized?

Reusable containers

Reusable containers are used repeatedly and, after emptying, are returned to the cycle.

This creates additional requirements:

• Document issuance and return
• Maintain container accounts
• Trace locations and responsible persons
• Return empties
• Monitor dwell times
• Organize cleaning and inspection
• Record damages
• Manage repairs
• Handle losses
• Make containers available again

Reusable containers therefore require active cycle management. A pure inventory management in one’s own warehouse is not sufficient.

What goals does container management pursue?

Ensure container availability

Production, warehousing and shipping should always have the required load carriers available.

Avoid bottlenecks

A looming shortage should become visible before it impacts production or delivery.

Optimize container inventories

The stock should be large enough to meet demand without holding too many load carriers unnecessarily.

Create transparency

Companies need an overview of inventories, locations, movements, balances and returns.

Shorten turnover times

The faster a reusable container is returned and reused, the more often it is available for further transports.

Reduce container losses

A traceable movement history helps clarify where a container was last used or to which partner it was handed over.

Reduce manual effort

Digital bookings and integrated processes can reduce paper vouchers, retroactive recording and manual reconciliation.

Support material flow

The container provisioning must be coordinated with material provisioning, production, warehousing and shipping.

Ensure container quality

Damaged, dirty or unsuitable containers must be identified early and removed from the available stock.

Make cycles more sustainable

Repeated use, demand-driven inventories and organized returns can reduce resource consumption and unnecessary transports.

What tasks belong to container management?

Manage container master data

For each container type, the relevant properties are recorded.

These can include:

• Container number
• Container type
• Designation
• Dimensions
• Weight
• Payload
• Volume
• Owner
• Value
• Reusable or single-use labeling
• Cleaning requirements
• Inspection requirements
• associated products
• permitted locations

Maintain stock

Container stock must be traceable by container type, location, owner and status.

Possible stock types are:

• own plant
• own warehouse
• production area
• supplier
• customer
• forwarder
• external service provider
• cleaning
• repair
• transit

Capture container movements

Every relevant issuance, return or relocation should be documented promptly.

Typical movements are:

• goods receipt
• goods issue
• internal relocation
• issuance to suppliers
• issuance to customers
• handover to carrier
• empty return
• return to owner
• handover to cleaning
• handover to repair
• scrapping or disposal

Maintain container accounts

Container accounts document which quantities of a load carrier have been exchanged between the company and a business partner.

A container account can be maintained, for example, for:

• customers
• suppliers
• carriers
• plants
• warehouses
• external service providers

The balance shows which partner would have to return or receive containers. To keep the balance meaningful, movements must be booked in full, timely and according to uniform rules.

Plan container demand

The future demand depends, among other things, on:

• production program
• customer orders
• delivery call-offs
• packaging regulations
• container contents
• transport frequency
• turnover time
• return behavior
• safety stock
• cleaning and repair duration

Dispose of empties

Empty load carriers must be provided where they are needed for production, order picking or shipping.

Control return

Return management includes:

• recognize return need
• inform partners
• plan pickup
• coordinate full and empty transports
• book return
• clarify discrepancies
• report container back in stock

Condition control

Containers can be damaged, dirty or incomplete when returned, depending on their use.

Possible status values are:

• available
• occupied
• in transit
• at business partner
• dirty
• to be checked
• blocked
• in repair
• decommissioned
• missing

Organize cleaning and repair

For certain containers, defined cleaning, inspection and repair processes must be followed.

Monitor costs

Possible costs include:

• acquisition
• rental
• pooling fees
• transport
• return
• cleaning
• inspection
• repair
• storage
• shrinkage
• disposal
• administrative overhead

How does a container cycle work?

A container cycle describes the path of a load carrier from its provisioning through use to return and reuse.

A simplified cycle can include the following steps:

1. Determine container requirements
2. Provide empty containers
3. Load containers
4. Record issuance or shipment
5. Transport containers
6. Remove goods
7. Update empties stock at recipient
8. Trigger return
9. Transport empties back
10. Book return
11. Inspect containers and, if necessary, clean
12. Provide containers again

Open, semi-open and closed container cycles

Closed container cycle

In a closed cycle, containers move within a clearly defined circle of participants.

The participating locations and partners are known. This makes rules, accounts and responsibilities comparatively unambiguous to define.

Semi-open container cycle

In a semi-open cycle, there is a defined core of participants; additionally, other partners or external stations may be involved.

Open container cycle

In an open cycle, containers can be exchanged between changing or not fully controllable participants.

As openness increases, the requirements for identification, booking quality, partner coordination and traceability rise.

Quantity booking or single-container tracking?

Companies must decide whether to track load carriers by quantity or as individual objects.

Quantity-based container management

In quantity-based management, it is booked how many containers of a type are at a site or with a partner.

It is particularly suitable when:

• containers are largely interchangeable
• the unit value is low
• no individual history is required
• inventory and balances management is in the foreground

Single-container tracking

With single-container tracking, each load carrier has a unique identification.

Depending on the solution used, this allows, among other things, to trace:

• individual movement history
• current or last booked location
• owner
• condition
• inspection date
• repair history
• dwell time
• associated order or transport

Single-tracking is especially suitable for high-value, scarce, customer-specific or security-relevant load carriers.

The additional information gain must be weighed against tagging, capture and integration effort.

Container management in purchasing, production and shipping

Container management in purchasing

In the procurement process, containers are needed to transport materials from the supplier to the company’s own location.

Relevant questions are:

• Which load carriers must the company provide?
• Which load carriers does the supplier provide?
• When are empty containers needed?
• How are they handed over to the supplier?
• Which quantities were returned with the delivery?
• Who bears costs in case of loss or damage?

Container management in production

Within production, containers connect storage, material provisioning, workstations, intermediate storage and finished goods areas.

If suitable containers are missing, materials cannot be provided or a finished operation cannot be further transported.

Container management in warehousing

The warehouse needs transparency about:

• available containers
• occupied containers
• empties
• blocked containers
• returns
• locations
• container accounts

Container management in shipping

In shipping, it must be checked whether there are enough suitable load carriers available for the planned deliveries.

Packaging regulations can specify:

• which container type is used
• how many parts a container contains
• how parts are positioned
• which protective means are required
• which markings should be applied
• which customer requirements apply

Container management in various industries

Automotive industry

In the automotive industry, standardized small load carriers, large load carriers, and special racks are commonly used.

Relevant requirements can include:

• tight delivery cycles
• delivery call-offs
• customer-specific packaging regulations
• high part variety
• cross-site loops
• clear container accounts
• rapid return of empties
• quality and cleanliness requirements

Machinery and plant engineering

For large or delicate components, customer-specific transport frames and special load carriers may be required.

Retail

In retail, pallets, roll containers, crates and other load carriers move between central warehouses, branches, suppliers and logistics partners.

Food industry

In the food industry, hygiene, cleaning, separation of product flows and traceability can be of particular importance.

Chemistry and pharmaceuticals

Depending on the contents and process, safety, cleaning, testing and documentation requirements can be relevant.

Electronics industry

Sensitive components may require special protective or transport containers.

Typical problems without systematic container management

Unknown inventories

Different lists and data records mean that no one reliably knows the actually available stock.

Container shortages

Containers are missing where they are needed for production, storage or shipping.

Excess stock

Due to uncertainty, additional containers are procured, even though other locations have sufficient empties.

Shrinkage

Container movements were not fully documented or responsibilities are not clearly defined.

Long dwell times

Empty containers remain unnecessarily long at customers, suppliers, forwarders or internal locations.

Inconsistent container accounts

Business partners maintain different balances and cannot clearly attribute movements.

High reconciliation effort

Differences are resolved by phone, email, and spreadsheets.

Unplanned new purchases

A lack of transparency can lead to last-minute purchases of containers.

Missing condition information

Damaged or dirty containers are mistakenly considered available.

Media breaks

Paper records are transmitted late or incorrectly into spreadsheets and systems.

How software supports container management

A container management software digitally maps inventories, movements, accounts and loops.

Possible functionalities include:

• Container master data
• Inventory management
• Container accounts
• Movement history
• Location assignment
• Partner assignment
• Returnable packaging requests
• Return management
• Dwell time monitoring
• Repair and cleaning status
• Discrepancy clearance
• Analyses
• Warnings
• Mobile data capture
• Interfaces to other systems

Barcode

A barcode can identify a container type or a single load carrier.

Capturing generally requires line-of-sight to the code and a suitable scanner or a mobile device.

RFID

RFID uses an electronic data carrier that is read via radio waves.

Whether RFID is suitable for a process depends, among other things, on range, environment, container material, data requirements and cost-effectiveness.

Mobile data capture

Smartphones, tablets or mobile scanners can support bookings directly at goods receipt, goods issue, ramp or storage location.

IoT sensors

For certain high-value or critical containers, additional sensor or location data can be used. The benefit must match the value of the container and the concrete information needs.

Container management with ERP

An ERP system connects container management with the business processes in which container movements occur.

These include:

• Purchasing
• Delivery call-offs
• Goods receipt
• Warehouse
• Materials management
• Production
• Picking
• Sales
• Shipping
• Transport
• Accounting

Deriving container movements from business transactions

A shipment can, for example, trigger both a goods movement and a movement of the used load carriers.

Linking container demand with orders

Customer orders, production quantities and packing regulations provide information about which containers are needed and when.

Linking container accounts with business partners

Suppliers, customers and forwarders can be linked to their respective container accounts.

Consider inventories and material flow together

The container supply is planned not in isolation from production, storage and shipping.

Allocate costs

Depending on process and system configuration, acquisition, rental, repair or loss can be mapped financially.

Container management with Abas ERP

Abas ERP connects container and packaging material processes with materials management, purchasing, production, warehousing, sales and shipping.

Manage packaging materials

Different packaging materials and load carriers can be mapped with their relevant attributes.

Model complex packaging structures

Depending on the specific process, different container and packaging levels can be connected.

Trace locations and movements

Container movements can be documented with the associated logistics processes.

Investigate dwell and residence times

Movement and inventory data provide a basis to detect unusual turnover times or long-term stock with individual partners.

Integrate data capture methods

Depending on the system landscape and process, manual bookings, barcode capture, RFID or connected mobile solutions can be used.

Connect automotive processes

For automotive suppliers, linking delivery call-offs, shipping, packaging materials and container movements is particularly relevant.

Which specific functions, interfaces and data capture methods are available must be checked depending on the used Abas version, configuration and connected solutions.

Key metrics in container management

Container stock

Shows the available quantity per container type, owner, location or process status.

Available stock

Considers only containers that can actually be used for a new deployment.

Turnover time

Measures the duration of a container turnover from outgoing to re-availability.

Dwell time

Shows how long containers stay at a location or with a business partner.

Throughput

Describes how often a container, or the average container stock, is used within a given period.

Shrinkage

Shows containers whose stock or whereabouts can no longer be traced.

Repair rate

Relates containers requiring repair to an appropriate reference quantity.

Return rate

Compares issued and returned reusable containers within a defined period.

Container balance

Shows the calculated balance of a container account with a business partner.

Utilization

Evaluates how well the capacity of a container is used during loading.

For each metric, the calculation, time period, data source and responsibility must be clearly defined.

Implementing container management: step by step

1. Analyze the starting position

First, the following is recorded:

• which container types are used
• how many containers are available
• who the owner is
• which sites and partners are involved
• how movements are documented today
• where bottlenecks and surpluses occur
• which costs arise

2. Document container cycles

For each relevant container type, describe the actual path between provisioning, use, transport, unloading and return.

3. Define goals

Possible goals are:

• Improve stock transparency
• Reduce bottlenecks
• Shorten turnover times
• Better understand shrinkage
• Reduce manual bookings
• Standardize container accounts
• Structure repair processes

4. Segment containers and partners

Not every load carrier requires the same administrative and tracking effort.

Relevant criteria are:

• Value
• Criticality
• Turnover quantity
• Interchangeability
• Lifespan
• Loss frequency
• Inspection requirement
• Number of participants

5. Define booking rules

It must be clear:

• which movement is booked
• when the booking occurs
• who is responsible
• which data are required
• how corrections are made
• how discrepancies are handled

6. Choose identification methods

Depending on the process, decide whether quantity booking, barcode, RFID or another identification is used.

7. Integrate system landscape

ERP, Materials Management, Transport Management, mobile applications and other systems require clearly defined roles and interfaces.

8. Implement a pilot process

A limited cycle with clear participants and measurable problems is suitable for an initial practical test.

9. Train employees and partners

Participants must understand:

• why bookings are necessary
• when they are performed
• which information is captured
• how errors are corrected
• who is responsible for discrepancies

10. Check results

After implementation, inventories, turnover times, discrepancies and recording quality are compared with the starting position.

Typical mistakes in container management

Only consider your own site

Returnable containers often move across corporate boundaries. A purely internal view would therefore be incomplete.

Booking container movements belatedly

Subsequent recording leads to outdated inventories and makes traceability more difficult.

Using inconsistent booking rules

When sites and partners book the same processes differently, conflicting balances arise.

Tracking every container individually

Individual tracking creates additional effort and is not required for every standardized or low-value container.

Only recording stock

Stock alone does not automatically show why containers are missing, how long they are in transit or where delays occur with which partner.

Not considering conditions

A damaged or dirty container must not be planned as available.

Not involving business partners

An cross-company loop only works if involved partners treat data and movements according to agreed rules.

No responsibilities defined

Without clear responsibilities, container accounts, discrepancies and returns remain unprocessed.

Choosing software before the process

The solution must fit the container cycle, the desired accuracy and the existing system landscape.

Expecting unproven technological advantages

RFID, IoT or AI do not solve unclear master data, responsibilities or booking rules. Technology can only build on a defined process.

Conclusion: Container management connects load carriers and material flow

Container management is much more than the management of pallets, crates or cage pallets. It connects load carriers with material flow, production, warehousing, shipping and collaboration with suppliers, customers and logistics service providers.

The central goal is to make suitable load carriers available on demand. At the same time, inventories, turnover times, shrinkage and administrative effort should remain controllable.

A reliable inventory management is as important as the complete capture of container movements. Container accounts show which load carriers have been exchanged between business partners. Dwell and turnover times reveal where returns are delayed or container stock is tied up.

Software supports the central management of this information. Barcode, RFID and mobile applications can facilitate bookings directly at the process location. The suitable identification method depends on the container value, the required traceability and the complexity of the loop.

An ERP system expands container management to the business context. Customer orders, delivery call-offs, goods receipts, production requirements, packing regulations and shipping operations provide information about current and future container needs.

However, the decisive factor remains process quality. Unclear responsibilities, late bookings and inconsistent container accounts cannot be solved by new technology alone. Companies need binding booking rules, well-maintained master data and coordinated collaboration with all involved partners.

When properly implemented, container management provides transparency over inventories and cycles, supports reliable supply for production and shipping, and provides a solid basis for the economical use of load carriers.
