NOVEMBER - DECEMBER 2025ELECTRICAL BUSINESS REVIEW8IN MY OPINIONBy Bridget Grewal, Director of Packaging Continuous Improvement, Magna InternationalThe ability to track shipping containers filled with automotive components is quite valuable in today's just-in-time production world. Identifying when shipments will be delayed, or correcting the path of shipments off course, helps us ensure our manufacturing facilities can plan accordingly and meet the production needs of our customers. Until recently, leveraging technology to track returnable containers, those that are specially fabricated and hold significant value as a company asset, has been too expense. However, as is common with tech, the cost for implementing and using RFID, Bluetooth Low Energy (BLE) and low power, wide area (LBWA) solutions has come down, making the use of them now cost effective.Before we look ahead at how these technologies can greatly improve tracking for container fleets, let's review some history around this kind of effort. When I worked for a large automaker in the 1990s, tracking returnable shipping equipment started to gain traction as the industry adopted the use of standard hand-held and bulk containers. These kinds of fabricated containers held value, could be reused and replaced expendable cardboard shipping boxes. In 1994, our team of seven people launched returnable shipping assets valued at $21 million that year. The idea that we could dramatically lower the use of cardboard for shipping was a nod toward creating a more sustainable approach to moving parts from our suppliers to our assembly plants in North America.We built the cost of the returnable containers into the reimbursable packaging piece price, including an additional 4% to cover maintenance and repair of the fleet and lost containers. However, we quickly learned that controlling the movement of containers with packaging that all looks the same was very difficult and that 4% wasn't going to cover the loss we experienced. Shipments didn't always move directly from point A to point B. Sometimes, they sat in truck driver's driveway overnight, thereby delaying their expected delivery. I've since tried many ways to track containers ranging in value from as little as $5 to more than $1,500 in a cost-effective way. In the 1990s, using sensor technology wasn't financially feasible, but today, I see it as a much-needed tool to keep container fleets intact.The cost of tags and the infrastructure to scan and track them has come down substantially, and there are numerous service providers emerging with software to quickly identify containers that are out of cadence or off track. During the launch of a new container program, we can have manufacturers tag all the units with passive RFID or BLE tags. The RFID tags are the least costly, LEVERAGING TECHNOLOGY TO TRACK RETURNABLE SHIPPING CONTAINERS
