Obstruction of customs: negligent trailer-driver conduct now triggers joint liability and recovery of scanner repair costs. Negligent driver conduct causing damage to the Container Monitoring System (CMS) that leads to scanner breakdowns will render the transport operator and the container freight station (CFS) jointly responsible; repair costs will be recovered from them. Such negligent acts, including queue-jumping and apparent intent to avoid scanning, will be treated as obstruction of a customs officer and pursued under applicable customs and criminal law, alongside administrative recovery and enforcement measures.
