The advice follows a meeting between several UK hauliers, growers and Container Centralen to discuss "Operation Chip It", under which businesses must fit RFID tags to Container Centralen trolleys by 10 January 2011 to protect the pool against fakes.
A HTA representative said: "The HTA strongly urges all growers and retailers to review their Container Centralen trolley usage and register their requirements as soon as possible.
"Failure to do so could result in trolley gridlock as Container Centralen clients refuse to exchange trolleys that are not in the pool. With the concentrated peak period between Easter and the May Bank Holiday in 2011, this could bring the industry to a halt."
The issue has been highly controversial because of the £400 cost of scanners and fears that the system will be time-consuming. The HTA suggested agreements to remove the need to scan at every stage of collection and delivery.
