4. Additional regulatory and surveillance actions will be imposed on the subject shippers and subject freight forwarders who fail to submit or implement a corrective action plan (CAP) acceptable to the CAD, or comply with the applicable enhanced control and surveillance measures specified under the scheme. To better manage the potential risks on aviation safety, relevant entities in the air cargo industry would be notified such that they may also consider stepping up their control, surveillance and inspection measures on the consignments tendered by the subject shippers and/or subject freight forwarders in parallel, in accordance with their own risk management approach.

You may wish to step up control and surveillance measures on the above companies in accordance with your company‘s risk management approach.
