Since trusted shipper programs (C-TPAT, FAST And NEEC ) were established several years ago, participants have experienced reduced border wait times and improved just-in-time inventory delivery reliability. Established jointly by the U.S. Customs and Border Protection and its Mexican counterpart, Aduana, trusted shipper status was granted to shippers who met pre-approved security criteria. Their cargo travels in a secure supply chain and is pre-screened, resulting in fewer inspections and reductions in border crossing times. Even so, some companies choose not to join the programs. To find out why, researchers conducted a survey among manufacturers, assembly plants, customs brokers, importers, logistics providers and transportation companies. The survey revealed the reasons why some of the companies do not join trusted shipper programs, and the researchers recommended several ways membership can be increased. Among the recommendations, researchers suggest the establishment of a strategic plan that gains access to the leaders and decision-makers of manufactures to explain the benefits of joining the trusted shipper programs. Companies were also encouraged to form a partnership with public- and private-information providers to help decision-makers better understand the benefits of joining trusted shipper programs.
