On 17th April, Freight Waves published an article (informative and well worth reading) about the US air cargo supply chain. It looks at the effect of 9/11 on security in the supply chain. It looks at the security arrangements, such as how third-party industry participants who tender air cargo such as freight forwarders and third-party logistics firms (3PL) must be certified annually for the Indirect Air Carrier Standard Security Program, administered by the Transportation Security Administration (TSA). Shippers, freight consolidation centres and others can apply with the TSA to become a Certified Cargo Screening Facility (CCSF), and 2019 has seen introduction of the Third-Party Certified Canine Screening Program for private canine companies to perform security screening for air cargo at airline, handler, forwarder or other facilities. Air cargo shippers can also enrol and qualify, through an airline or indirect air carrier, in the TSA’s Known Shipper Management System. The article, after looking at the structures and organisations, then looks at technologies used, as well as sniffer dogs. Looking at air cargo entering the US, outside of US international air cargo bound for the US is managed through a Customs’ programme called Air Cargo Advance Screening (ACAS), which uses a risk-based approach and intelligence-sharing of many data sources to assess a shipment before boarding an aircraft. From 2021, all cargo boarded on all commercial transport aircraft will need to be 100% secured under ICAO requirements, which will drive further process changes for shippers, airlines and indirect air carriers.
